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).

</decisions>
Documentation (type)
Description of decisions for a case management tree. A generic view of this tree would be that each decision is deterministic, or based on probabilities which may depend on other decisions. Probabilistic decisions are described here.
In general, each decision has a name, a defined set of outcome values, and a set of dependent decisions mentioned by name. The following decisions, with their associated outcomes, are provided by the code (and may not be included here):
- case (uncomplicated only): Returns "UC1" if there is no recent history of a malarial case, or "UC2" if there is.
- result: Dependent on decision "test", this performs a parasite density test. Output is one of "none" (no test performed), "positive", "negative".
The following decisions must be described here:
- test (uncomplicated only): Outputs must be "none", "microscopy" or "RDT" to describe which test the "result" decision uses.
- treatment: Describes which treatment to use. Values aren't restricted but must match up with a treatment described in the corresponding "treatments" section.
- hospitalisation (complicated only): none, immediate or delayed.

</decision>
Documentation (type)
A decision describes rules for choosing between a set of values.
Lexically, it can contain symbols matching "[_.a-zA-Z0-9]+", round brackets: (), braces: {} and colons. Whitespace is ignored except to separate symbols.
Syntactically, it must match one TREE, where SYMBOL is a symbol described above. (Here, "x|y" means x or y, "x+" means x occurs once or more, brackets show grouping.) TREE := BRANCH_SET | OUTCOME BRANCH_SET := BRANCH+ BRANCH := DECISION '(' VALUE ')' ( ':' OUTCOME | '{' TREE '}' ) OUTCOME, DECISION, VALUE := SYMBOL
For each BRANCH_SET each BRANCH must result in the same DECISION. The DECISION must be one of the dependencies mentioned in "depends". This may be:
- another decision, in which case the VALUE immediately following in brackets must correspond to one of its output values. The BRANCH_SET immediately containing this BRANCH must represent each output value of the same decision exactly once, and no parent BRANCH_SET may be for the same DECISION.
- "p": this entry indicates a probabilistic decision. Where the value is a probability, the sum of all values for the BRANCH_SET must be 1 and the decision must be associated directly with OUTCOMEs (not sub-TREEs).
- "age": this entry indicates an age-test. The VALUE must have the form "a-b", indicating that this branch will be taken for individuals aged such that a <= age < b, where a,b are non-negative real numbers or the special value "inf", and a <= b. All VALUEs in the BRANCH_SET must cover all possible (non-negative real) ages, with no overlap (hence, smallest a must be 0 and greatest b must be inf).
Semantically, each OUTCOME must be one of the values associated with this decision.

Units: Dimensionless Min: 0.0 Max: 1.0
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 → ImmediateOutcomes → treatmentActions → CQ → clearInfections
<clearInfections
timesteps=int
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=int
Units: Timesteps Min: -1
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.
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.

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.

Describe an effect on emergence of pupa into adults: this value is the proportion of emerging pupa which are killed by this intervention.
This can be used as a crude way of modelling larviciding. It ca also be used to increase emergence by giving a negative value. The emergence rate is "old rate" × (1 - factor) where factor is the value given here; thus, for example, using -1 will double emergence.

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).

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 net on survival mosquitoes as they seek to bite a human after choosing that human, relative to the same person not sleeping under a net. Parameterisations should take into account that mosquitoes do not always bite indoors.

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.

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.

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.

<restrictToSubPop
id=string

Documentation (type)
If this element is specified, deployment is restricted to some sub-population (specified via the "id" attribute); otherwise the target population is the entire simulated population. Either way, other deployment restrictions (age, time, number of vaccine doeses) still apply.
Attributes
Sub-population identifier
id=string
The identifier (short name) of the sub-population (i.e. the "id" of some intervention component). Also see the "complement" attribute.
Complement
complement=boolean
Default value: false
If this is not specified or is false, deployment is restricted to the sub-population of people protected by the intervention component who's id is given. If complement is set to true, deployment is instead restricted to the complement of that sub-population, i.e. to those
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.

Units: mosquitoes. emergence: seasonality of emergence pupa into adults. Units: mosquitoes. larvalResources: seasonality of larval resources. Units: X.
Annual EIR
annualEIR=double
Units: Inoculations per adult per annum Min: 0
If this attribute is included, EIR for this species is scaled to this level. Note that if the scaledAnnualEIR attribute of the entomology element is also used, EIR is scaled again, making this attribute the EIR relative to other species. With some seasonality inputs, this attribute is optional, in which case (if scaledAnnualEIR is also not specified) transmission depends on all parameters of the vector. With some seasonality inputs, however, this parameter must be specified.

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.

Standard deviation
multStdDev=double
Units: None Min: 0
Each human is assigned a weight multiplier from a normal distribution with mean 1 and this standard deviation at birth. His/her weight is this multiplier times the mean from age distribution. A standard deviation of zero for no heterogeneity is valid; a rough value from Tanzanian data is 0.14.
