Abstract
Busia and Malaba are the busiest border crossing points for truckers using the Northern Corridor connecting
landlocked countries of Uganda, DR Congo, South Sudan and parts of Rwanda to Mombasa port. On average, Malaba and
Busia clears 1000 and 600 trucks respectively per day. Delays in clearance of the trucks causes long queues at crossing points
and influx of truckers in these respective towns. The truckers spent this time in the company of commercial sex workers and
interact with the local communities in these towns, hence this is a conduit of spread of HIV/AIDS in these regions. This paper
designed a model to study the HIV/AIDS dynamics in this border towns. The reproduction number, the disease-free
equilibrium and endemic equilibrium points determined using the Next Generation Matrix (NGM) method. From the analysis
of the model, it is found that delays in clearance time increases the force of infections from females to males. It is found out
that also found out that increase in force if infections to males from females increases the male HIV infections. This is due to
prolonged time of sexual interactions as the trucks await clearance and also due to higher number of male truckers than
females. Furthermore, the analysis shows that delays in clearance time leads to increase in both male and female HIV/AIDS
infections which causes an increase in the number of AIDS cases in this border crossing points
