| Abstract: |
| Inspired by Kouakep [16], we consider in this note a wellposed model with differential susceptibility and infectivity adding continuous age structure to an ODE model for a ``Baka" pygmy group in the East of Cameroon (Africa). Assuming a very low contribution of carriers to infection compared to acute infection, we estimate a probability $p(a)$ (to develop symptomatic Hepatitis B state at age $a$) and acute carriers' transmission rate. The value $R_0$ = 2:67 $>$ 1 of the basic reproduction number estimated from
data in the east of Cameroon confirms that HBV is endemic in the Baka pygmy group. |
