Attributes

Start of monitoring

startDate=string

An optional date for the start of monitoring. If given, dates may be used to specify when other events (surveys, intervention deployments) occur; alternately times relative to the start of the intervention period may be used to specify event times. Setting this to 1st January of some year might simplify usage of dates, and putting the start a couple of years before the start of intervention deployment (along with some extra surveys) may be useful to check transmission stabilises to the expected pre-intervention levels. As an example, if this date is set to 2000-01-01, then the following event times are equivalent (assuming 1t=5d): 15t, 75d, 0.2y, 2000-03-16. Must be in the form YYYY-MM-DD, e.g. 2003-01-01.

option

Attributes

Delay between reports

period=string

Units: User defined (default: steps)

Delay between reports; typically one time step but can be greater. Can be specified in steps (e.g. 1t) or days (e.g. 5d).

During initialization

duringInit=boolean

Units: Days Min: 1 Max: unbounded

Also output during initialization. By default this is disabled (only intervention-period data is output). This should not be used for predictions, but can be useful for model validation. In this mode, 'simulation time' is output as the first column (in addition to 'timestep'), since 'timestep' is dis- continuous across the start of the intervention period.

option

→ scenario → monitoring → continuous → option

<option
    name=string
  [ value=boolean ] DEFAULT VALUE true
  />

Attributes

Option name

name=string

Name of an option (monitoring measure or model option).

Indicator of whether option is required

value=boolean

Default value: true

Option on/off switch (true/false). Specifying value="true" is the same as not specifying a value; specifying value="false" explicitly turns the option off. If an option is not mentioned at all, it is left at its default value (normally off, but in a few cases, such as some bug-fix options, on).

</SurveyOptions>

option

Documentation (element)

List of all active survey options. See model/mon/OutputMeasures.h for a list of supported outputs. Should also be on the wiki.

Attributes

Report only for new cases

onlyNewEpisode=boolean

Default value: false

If set, some statistics exclude humans who have been treated in the recent past (precisely, when the time of last treatment was before the current step and no more than health-system-memory days/steps ago). This is a rough replacement for the REPORT_ONLY_AT_RISK option, with one difference: the maximum age of treatment for REPORT_ONLY_AT_RISK was fixed at 20 days. Affected measures include (as of version 35): nHost (0), nInfect(1), nExpectd (2), nPatent (3), sumLogPyrogenThres (4), sumlogDens (5), totalInfs (6), totalPatentInf (8), sumPyrogenThresh (10), nSubPopRemovalFirstEvent (62), sumAge (68), nInfectByGenotype (69), nPatentByGenotype (70), logDensByGenotype (71), nHostDrugConcNonZero (72), sumLogDrugConcNonZero (73).

  />

Attributes

Option name

name=string

Name of an option (monitoring measure or model option).

Indicator of whether option is required

value=boolean

Default value: true

Number identifying measure in output

outputNumber=int

Number identifying this monitoring measure in the output file (3rd column). Normally this is determined from the measure, but it can be set manually, e.g. for when the same measure is recorded twice (to accumulate across different categories).

Report by age category

byAge=boolean

If true, the measure is reported for each age category. If false, values are summed across all age categories and only the sum reported. If not specified, separate categories will be reported if the measure supports this.

Report by cohort

byCohort=boolean

If true, the measure is reported for each cohort separately. If false, values are summed across all cohorts and only the sum reported. If not specified, separate categories will be reported if the measure supports this.

Report by mosquito species

bySpecies=boolean

If true, the measure is reported for each mosquito species separately. If false, values are summed across all species and only the sum reported. If not specified, separate categories will be reported if the measure supports this.

Report by parasite genotype

byGenotype=boolean

If true, the measure is reported for each parasite genotype separately. If false, values are summed across all genotypes and only the sum reported. If not specified, separate categories will be reported if the measure supports this.

Report by drug type

byDrugType=boolean

If true, the measure is reported for each drug type separately. If false, values are summed across all drug types and only the sum reported. If not specified, separate categories will be reported if the measure supports this.

Survey times (time steps)

surveyTime

Documentation (element)

List of survey times

Attributes

Detection limit for parasitaemia

detectionLimit=double

Units: parasites/microlitre Min: 0

Deprecated: limit above which a human's infection is reported as patent. Alternative: do not specify this; instead specify "diagnostic".

Name of monitoring diagnostic

diagnostic=string

Name of a parameterised diagnostic to use in surveys (see scenario/diagnostics).

Survey time

→ scenario → monitoring → surveys → surveyTime

<surveyTime
  [ repeatStep=string ]
  [ repeatEnd=string ]
  [ reported=boolean ] DEFAULT VALUE true
  >
    string
</surveyTime>

Documentation (element)

Units: User defined (defaults to steps) Min: 0

Time of a survey. A report will be made for those measures enabled under SurveyOptions. Reported data is either from the moment the survey is done (immediate data) or is collected over the time since the previous survey, or in some cases over a fixed time span (usually one year).

Times can be specified in time steps, starting from 0, or as a date (see monitoring/startDate), or in days (e.g. 15d) or years (e.g. 1y). Relative times mean the time since the start of the intervention period, and must be non-negative (zero is valid, but some measures, e.g. nUncomp, will be zero).

The simulation ends immediately after the last survey is taken.

Attributes

Step of repetition

repeatStep=string

Units: User defined

See repeatEnd's documentation.

End of repetition (exclusive)

repeatEnd=string

Units: User defined

Either both repeatStep and repeatEnd should be present or neither. If present, the survey is repeated every repeatStep timesteps (i.e. if t0 is the initial time and x is repeatStep, surveys are done at times t0, t0+x, t0+2*x, ...), ending before repeatEnd (final repetition is the one before repeatEnd). Note that repeatEnd may be specified as a date but repeatStep must be a duration (days, steps or years).

reported

reported=boolean

Default value: true

For normal surveys, reporting=true. If set false, quantities are measured but not reported. The reason for doing this is to update conditions set on reportable measures. Multiple surveys may be given here for the same date, e.g. if using "repeatStep" for both reporting and non-reporting surveys. These are combined such that a maximum of one survey is carried out per time-step, and the survey is reported if any of the listed surveys for this date is configured as "reporting". Note that adding non-reporting surveys will not affect value output by reported surveys, with the exception that generated psuedo-random numbers may be altered (specifically, when any stochastic diagnostics are used in surveys).

subPop

Documentation (element)

Allows the configuration of multiple cohorts (output segregated according to membership within specific sub-populations).

If this element is omitted, monitoring surveys cover the entire simulated human population.

It does not affect the "continuous" outputs (these never take cohorts into account).

Sub-population

→ scenario → monitoring → cohorts → subPop

<subPop
    id=string
    number=integer
  />

Documentation (element)

Consider a certain sup-population a cohort, and segregate outputs according to membership. Where multiple sub-populations are listed, segregate output according to all combinations of membership: e.g. if sub-populations A and B are listed, there will be outputs for "member of A and B", "member of A but not B", "B but not A" and "not a member of A or B". Listing n sub-populations implies 2^n sets of outputs (each is further segregated by age groups, survey times and enabled output measures, which could lead to excessive program memory usage and output file size).

To identify outputs, each sub-population has a power of two number as identifier (see "number" attribute). Each of the 2^n output sets is identified by a number: the output set is the output from humans who are members in some set of sub-populations (S1, S2, ...) and not members in some others (T1, T2, ...); the number identifying the set is the sum of the numbers identifying the sets S1, S2, etc.

In the output file, the output set is identified by multiplying this number by 1000 then adding it to the age group column.

Attributes

Sub-population identifier

id=string

Textual identifier for the sub-population (i.e. for an intervention component, since sub-populations are defined as the hosts an intervention component is deployed to).

Sub-population number

number=integer

Units: dimensionless Min: 1 Max: 2097152

Number identifying a sub-population; used to define identifiers of output sets. This number must be a power of 2 (i.e. 1, 2, 4, 8, ...). See documentation of subPop element.

Documentation (type)

Simple treatment model, targetting liver- and/or blood-stage infections. This is all-or-nothing treatment which, when deploymed, completely clears all infections of the targetted stages. This makes it unsuitable for modeling resistance, but suitable for use with simple infection models.

Infections are considered liver-stage when less than five days old and blood-stage after that. Effects are described independently for the two stages.

Attributes

Length of liver-stage effect

Units: User defined

Controls action on liver-stage infections. 0 means no action, -1 step is a compatibility option to act like treatment before schema version 32 (which removed infections retrospectively), 1 step or any duration which equals some whole number of steps n>0 means to clear all liver-stage infections found on the next 1 or n steps. Note on -1 compatibility option: the main difference to 1 step (clearing on the next timestep) is that parasite densities will be reduced immediately, and thus from the point of view of surveys and mass screen and treat interventions a peak in density which is immediately treated through case management will not be seen. Can be specified in steps (e.g. 1t, -1t) or days (e.g. 5d).

Units: User defined

Controls action on blood-stage infections. 0 means no action, -1 step is a compatibility option to act like treatment before schema version 32 (which removed infections retrospectively), 1 step or any duration which equals some whole number of steps n>0 means to clear all blood-stage infections found on the next 1 or n steps. Note on -1 compatibility option: the main difference to 1 step (clearing on the next timestep) is that parasite densities will be reduced immediately, and thus from the point of view of surveys and mass screen and treat interventions a peak in density which is immediately treated through case management will not be seen. Can be specified in steps (e.g. 1t, -1t) or days (e.g. 5d).

It is sometimes desirable to model delays to treatment-seeking in uncomplicated cases. While treatment of drugs can be delayed within case management trees to provide a similar effect, this doesn't delay any of the decisions, including diagnostics using the current parasite density.

Instead a list of dailyPrImmUCTS elements can be used, describing successive daily probabilities of treatment (sum must be 1). For example, with a list of two elements with values 0.8 and 0.2, for 80% of UC cases the decision tree is evaluated immediately, and for 20% of cases evaluation is delayed by one day.

For no delay, use one element with a value of 1.

Attributes

interpolation

interpolation=("none" or "linear")

Interpolation algorithm. Normally it is desirable for age-based values to be continuous w.r.t. age. By default linear interpolation is used. With all algorithms except "none", the age groups are converted to a set of points centred within each age range. Extra points are added at each end (zero and infinity) to keep value constant at both ends of the function. A zero-length age group may be used as a kind of barrier to adjust the distribution; e.g. with age group boundaries at 15, 20 and 25 years, a (linear) spline would be drawn between ages 17.5 and 22.5, whereas with boundaries at 15, 20 and 20 years, a spline would be drawn between ages 17.5 and 20 years (may be desired if individuals are assumed to reach adult size at 20). Algorithms:

none: input values are used directly
linear: straight lines (on an age vs. value graph) are used to interpolate data points.

Prophylactic treatment

→ scenario → healthSystem → DecisionTree5Day → treatmentSevere → clearInfections

<clearInfections
    timesteps=string
    stage=("liver" or "blood" or "both")
  />

Documentation (element)

This clears infections according to several options: it can clear all blood stage infections, all liver stage infections or both, and it can act on multiple timesteps. To have a probability of no action add another treatment option (which does nothing) and set the probabilities of selection appropriately.

This allows immediate (legacy) or delayed action, a prophylactic period, and selection of which stages are targeted. It is a simple model but appropriate enough for use with the five day timestep when assuming no resistance and that drug failure is mainly caused by bad drugs or compliance.

The old treatment action for the five-day timestep model is essentially this, with immediateAction (timesteps=-1) and stage=both, except for the IPT model's SP action, which was more like with timesteps>1 and stage=blood.

Attributes

Length of effect

timesteps=string

Units: User defined (defaults to steps)

The number of timesteps during which this action remains in effect (e.g. 2 means clear infections during the next two timestep updates). Full clearance of the targeted stages occurs during this time. A special value of -1 means act immediately (retrospectively); this the old behaviour. A value of 1 means act on the next timestep only. Both of these can be thought of as a model for short-acting effective drug treatment; the main differences are that the latter means parasite densities will remain high from the point of view of surveys and diagnostics (i.e. mass screen and treat) used before the next timestep and that the latter will also remove infections starting the next timestep. Arguably the latter is a better model, but the differences are perhaps small, excepting where immediate treatment of fevers (i.e. through the health system) can hide high parasite densities from reporting and mass-screen-and-treat diagnostics. For use by interventions, the latter model has nicer behaviour in that the order of deployment of multiple interventions deployed at the same time does not matter, and that the former model retrospectively treats infections which may already have caused fever, thus may have a lower health impact than it should. It is recommended to use the new model (value 1, or greater than 1 if prophylactic effect is desired) unless wanting to emulate the old behaviour. Values of 0 or less than -1 are not allowed. Can be specified in steps (e.g. 1t, -1t) or days (e.g. 5d).

Target stage

stage=("liver" or "blood" or "both")

Controls whether liver-stage or blood-stage infections are cleared, or both. Infections are considered liver-stage for one 5-day timestep, blood-stage but pre-patent for some number of timesteps (latentp - 1), then start the patent blood stage. If stage is set to "liver", infections are only cleared during their first timestep; if stage is set to "blood", infections are cleared during pre-patent and patent blood stages; if stage is set to "both" all infections are cleared. The old behaviour (oddly considering the drugs it is meant to emulate) is to clear both stages, except for the IPT model of SP action, which cleared only patent blood-stage infections.

Units: User-defined (defaults to years) Min: 0

(Time) scale parameter of distribution: this is either the age of complete decay (smooth-compact, step and linear functions) or the age at which the parameter has decayed to half its original value (exponential, weibull and hill). Not used when function="constant" (i.e. no decay). This value can be specified in years, days or steps (e.g. 2y, 180d or 100t). When the unit is not specified years are assumed. The value is used without rounding except when sampling an age of decay, when the rounding happens as late as possible.

Note that with m=0, the median of the variable and the median value of L is unchanged, and thus the time at which the median decay amongst the population of decaying objects reaches half (assuming exponential, Weibull or Hill decay) is L.

Traps attract and kill mosquitoes. They are modelled as a non-human-host where the probability of mosquitoes surviving feeding is zero (since otherwise the simulator would assume surviving mosquitoes have had a blood meal), and where this "host" is initially not present.

Each deployment has a fixed maximum lifespan, after which the traps from that deployment are removed (it is up to the user whether this is after availability is effectively zero or sooner, either coinciding with a redeployment or causing a reduction in overall effectiveness of traps).

Documentation (element)

A parameterisation of an effect achieved by one component of an intervention. (An intervention is described as the effects of a set of components plus deployments of those components. This describes the components individually, not deployments or which components comprise an intervention.)

Each element describes one component: its effects, decay of the(se) effect(s), and related stuff (e.g. description of indirect decay and of usage levels).

Different interventions can deploy the same component to the same perso. In most cases this will just deploy a fresh instance (e.g. a new bed net will replace the old (nobody uses multiple bed nets), or a new drug dose will act on top of previous doses, or in the case of a vaccine, effect depends on the total number of previous inoculations (including from other interventions).

Where multiple components of the same type (but with different ids) are deployed (whether within a single intervention or by multiple interventions), they act independently (e.g. two bed nets deployed to a single host would act to reduce attractiveness or survival of mosquitoes biting that host twice — this may be useful to simulate some novel vector intervention since the two nets may have separate parameters).

This can be combined with MDA to achieve mass screen and treat (MSAT) or other types of mass screening intervention.

When deployed to a host, this simulates a test of patent malaria (microscopy, RDT or some such), then triggers deployment of whichever intervention components are configured (deployments for both positive and negative test outcomes can be configured).

The use of the screening itself is reported (if enabled), but not the outcome. Deployment of interventions triggered by the screening may be reported, however.

Decay curve for insecticide content of nets. Documentation: see DecayFunction type or https://github.com/SwissTPH/openmalaria/wiki/ModelDecayFunctions

The distribution of decay rates over nets is covariant with the distribution of ripRate and holeRate over nets. This distribution is generated by taking one sample per net from a Gaussian distribution with mean 0 and standard deviation 1. For each variable, the sample is multiplied by the respective sigma and a constant added such that, once exponentiated, the mean of the variable over nets is 1. The variable is then exponentiated and multiplied by the required mean rate for the respective variable.

Specifies the rate at which nets are disposed of over time. Documentation: see DecayFunction type or https://github.com/SwissTPH/openmalaria/wiki/ModelDecayFunctions

In the current model, nets are disposed of randomly (no correlation with state of decay) such that the chance of each net surviving until age t is the value of this decay function at time t. Equivalently (where a large number of nets are distributed at the same time), the proportion of nets remaining in use should match this decay function over time.

Humans are removed from the intervention component's sub-population on disposal (attrition) of their nets. Currently this event is not reported.

Effect of IRS on attractiveness of humans to mosquitoes relative to an unprotected adult human. Parameterisations should take into account that mosquitoes do not always bite indoors.

Attractiveness of the human is multiplied by exp(P×log(p)) where P is the insecticide factor, p=1−exp(-insecticideContent×insecticideScalingFactor).

Documentation (element)

Units: dimensionless Min: 0 Max: 1

Effect of IRS on survival mosquitoes as they seek to bite a human after choosing that human, relative to the same person not protected by IRS. Parameterisations should take into account that mosquitoes do not always bite indoors. This parameter has been added since some data shows IRS to have a preprandial killing effect.

Killing proportion is calculated as K = B + P×p where B is the base (without protection) probability of death, and P is the insecticide factor, p=1−exp(-insecticideContent×insecticideScalingFactor).

Survival of mosquitoes is adjusted via multiplication by (1−K) / (1−B). To keep this in the range [0,1], we require that B+P ≤ 1 and P ≥ 0.

Documentation (element)

Recruitment of a host into a sub-population.

All human-targeting intervention deployments recruit simulated humans into a sub-population which can be used for the purposes of cumulative deployment, deployment only to a sub-population and defining a cohort. This pseudo-intervention can be used to define a sub-population without also deploying some intervention.

Documentation (type)

Each human intervention component corresponds to a sub-population: those who have received or are considered to be protected by the intervention component. Humans automatically become members of this sub-population when receiving an intervention component; this element controls how humans are removed from the sub-population.

ITN attrition also removes humans from sub-populations.

Note that sub-populations do not directly correspond to an intervention's effects: lack of effectiveness does not imply removal from the sub-population (except as explicitly configured here) and removal from the sub-population does not halt an intervention's effects.

Sub-populations may be used to define a cohort, to restrict deployment of other interventions and to use cumulative deployment mode. A sub- population may or may not correspond (roughly) to humans protected by some intervention.

Attributes

Time to first episode only

onFirstBout=boolean

Default value: false

If true, remove individuals from the sub-population at the start of the first episode (start of a clinical bout) since they were recruited into the sub-population. This is intended for cohort studies which measure time to the first episode, using active case detection. Reports delayed due to health-system memory are forced out when this occurs. Note that this can increase the number of uncomplicated cases reported across the entire population; for this reason reports are not forced on recruitment or most removal options. This does not prevent re-recruitment in the case that recruitment settings could conceivably recruit the same individual twice.

Time to first treatment only

onFirstTreatment=boolean

Default value: false

If true, remove individuals from the sub-population when they first seektreatment since they were recruited into the sub-population. This is intended for cohort studies which measure the time to first episode, using passive case detection. Reports delayed due to health-system memory are forced out when this occurs. Note that this can increase the number of uncomplicated cases reported across the entire population; for this reason reports are not forced on recruitment or most removal options. This does not prevent re-recruitment in the case that recruitment settings could conceivably recruit the same individual twice.

Time to first infection only

onFirstInfection=boolean

Default value: false

If true, remove individuals from the sub-population at completion of the first survey in which they present with a patent infection since they were recruited into the sub-population. This intended for cohort studies which measure time to the first infection, using active case detection. Reports delayed due to health-system memory are forced out when this occurs. Note that this can increase the number of uncomplicated cases reported across the entire population; for this reason reports are not forced on recruitment or most removal options. This does not prevent re-recruitment in the case that recruitment settings could conceivably recruit the same individual twice.

Remove from sub-population after

afterYears=double

Units: Years Min: 0

If given, membership to the sub-population of humans who have received this intervention component expires after the given number of years. Note that future deployments renew membership (e.g. if this parameter is 4 years and the intervention is redeployed 3 years from now, expiry happens after 7 years). This provides a crude way of modelling a cohort protected by some intervention. A few interventions provide more detailed ways of modelling expiry of protection. In any case, "expiry of protection" is an abstract concept and does not imply that all protection has ceased, even in the simulator. This may also be useful for cumulative deployment. Minimum duration is zero, which implies the human is effectively never a member of the sub-population; a duration of one timestep implies the human is a member of the sub-population while any futher interventions are deployed on the same time as this human becomes a member and on the next update of the human (including transmission and health system events) but not beyond that. If this attribute is not given, the simulated human is a member until death or some other option triggers removal. Input is rounded to the nearest time step.

Documentation (element)

If conditions are specified, deployment of this intervention will only go ahead if all specified conditions are true. Condition statements are evaluated only during surveys, so deployment is enabled or disabled depending on the results of the most recent survey. So called unreported surveys can be used to reevaluate conditions without increasing granularity of output.

Conditions are evaluated for the whole population, not for individual age-groups or cohorts.

This affects all types of deployment.

Cumulative coverage

→ scenario → interventions → human → deployment → timed → cumulativeCoverage

<cumulativeCoverage
    component=string

Documentation (element)

If this element is not specified, standard deployment occurs, where a portion of the population as given by the coverage property of this campaign is selected, and interventions are deployed to all of these people (regardless of previous coverage).

If this attribute is specified, instead, the population is divided into two sets: those who are a member of a certain sub-population and those who are not (see "subPopRemoval" element). If the proportion of people in the first set is less than the desired coverage, then the proportion of people from the second set needed to increase total coverage to the desired coverage is calculated. This proportion is then used as the probablity of selection from the second set into a third set of people who then receive all interventions deployed by this campaign.

Note that selection is stochastic so the final coverage level may not be exactly that desired. Note also that the component used when selecting people need not actually be one of the components deployed by this intervention, although that is the intended use case.

locus

Documentation (element)

A specification of genotypes of infection parasites.

May be omitted; in this case there is no modelling of genetic differences of infections (resistance, fitness).

Attributes

samplingMode

samplingMode=("initial" or "tracking")

This controls how genotypes are determined for new infections during the intervention period. Prior to this (in initialisation phases), genotypes are always sampled using the specified initial frequencies. Mode "initial" continues to sample genotypes using initial frequencies (i.e. independent of the success of parent generations of parasites). Mode "tracking" samples genotypes based on the success parent generations of parasites have in infecting mosquitoes, tracked per genotype. It is possible that in the future a recombination option will be added to this list, however designing a suitable model is not trivial.

Locus

→ scenario → parasiteGenetics → locus

<locus
    name=string
  >
IN THIS ORDER:

</locus>

allele

Documentation (element)

Describes a locus, or a point at which an infection may vary. The genotype of an infection is determined by choosing one allele at each locus. Initial frequencies of alleles are specified independently for each locus, but subsequent infections are selected according to success of genotypes.

Alleles at loci can affect fitness and resistance to any number of drugs.

Attributes

Attributes

Name

name=string

Name of the allele; used to refer to it elsewhere.

Initial frequency

initialFrequency=double

Specification of how commonly this allele occurs during warmup relative to other alleles of the same locus. During the simulation's initialisation phases, the frequency at which each allele of each locus occurs is fixed. After the initialisation phase, frequency of alleles is modelled as an emergent property of the success of genotypes.

Fitness factor

fitness=double

Fitness factor of the allele. This is multiplication factor used to speed up or slow down replication of parasites. For example, if a genotype has an allele with a fitness factor of 1 at one locus and another allele with a fitness factor of 0.8 at a second locus, then the parasites with the genotype will replicate 20% slower than the baseline.

Parasite density units / methodology

units=("Other" or "Garki" or "Malariatherapy")

Parasite densities, as estimated according to standard microscopy methods, the Garki method, and as derived from Malariatherapy data are not equivalent. Internally, a "bias" factor is used to convert values estimated by one methods to values comparable with another (see AJTMHv75 supplement 2 pp20-21). This option allows specification of which methodology the density given in the diagnostic specification is measured with. Values allowed are: Malariatherapy, Garki and Other. If not specified, Other is assumed, unless the GARKI_DENSITY_BIAS model option is used, in which case this option must be specified.

This element defines probabilites when and how many hypnozoites are released from the liverstage into the blood.

The gap between the start of a new brood of hypnozoites and its release are defined as follows:

latentP + latentRelapseDays + randomReleaseDelay

randomReleaseDelay is based on one or two lognormal distributions, which are defined in firstRelease and optionally secondRelease.

You can define 2 release distributions, which get added together and represent the probability of hypnozoites which get released before winter (first release) or after (second release).

You can omit the secondRelease element if no release to the blood happens after winter.
