Open-Population HIV Transmission & Demographics Engine
Stochastic Inbound & Outbound Migration Rates with Dual Barrier Protection
1. Gender Demographics
Definition & Biological Reality:
Female Population Ratio: Percentage of females in the population. Females face up to double the transmission risk per penile-vaginal act due to mucosal surface area and anatomical vulnerability.
2. Migration Dynamics
In & Out FlowDefinition & Migration Logic:
Monthly Turnover Rate: Percentage of people moving out and replaced by arrivals monthly.
Inbound Prevalence: Probability that a brand-new arrival entering the community is already infected.
Outbound Selection Bias: Targeted probability rate of infected individuals exiting the community cohort.
3. Barrier & Medical Defense
Definition & Protection Logic:
Condom Usage Frequency: Ratio of sexual acts using physical protection (~80% reduction).
Continuous PrEP Days: Days on PrEP building tissue concentration up to maximum ~99% effectiveness.
4. Adherence Regularity
Definition & Habit Logic:
PrEP Daily Adherence: Probability of maintaining daily pill intake. Lapses lead to fast tissue concentration decay.
5. Activity Rate
Definition & Exposure Logic:
Monthly Exposure Acts: Number of potential exposure encounters per person monthly.
6. Population Scale
Definition & Scale Logic:
Population Scale: Number of individual active digital twin units simulated in real time.
