📍 Select KFD District — Auto-Fill Simulation

Built-in data from kfd_new1.php for Chikkamagaluru and Shivamogga. Selecting a district updates all mapped dashboard inputs and reruns the simulation.

👤 Human Basic Reproduction Number — R_H

Complete human-focused analysis using your supplied R_H equation, with epidemiological simulation, R_H(t), what-if, sensitivity, control comparison and district analysis.

R_H = − H_Sβ_MH(α−1)N_Mδ_M + β_nHθN_T(G+δ_T) + β_PHN_Pκ

Definitions: H_S = susceptible humans; N_T, N_P, N_M = total ticks, primates and mammals. α becomes active at the intervention day in the KFD simulation.

R_H Parameters

Formula only

Human population compartments are linked to the Simulation Dashboard. Susceptible humans are calculated automatically.

Human Population Compartments

Total Human Population (N_H) Infected Humans (H_I) Recovered Humans (H_R) Vaccinated Humans (H_V) Susceptible Humans (H_S) — automatic

H_S = N_H − H_I − H_R − H_V

Other quantities appearing in the supplied R_H equation are shown below.

Note: N_T, N_P and N_M are calculated totals from the corresponding compartments and are shown as live read-only values.

Run the simulation to calculate R_H.

Human R_H Interpretation

—

R_H<1 / R_H>1 is interpreted here according to the supplied index. This does not replace the existing KFD NGM-based R₀.
