C
limate change has been suggested to elicit significant impact on the interactions between pathogens and their hosts. Vector-
borne diseases are predominantly sensitive to climatic factors because temperature variability can alter vector development
rates, transmission dynamics, as well as cause alteration in their geographical distribution. Schistosomiasis, ranked the second
most widespread among neglected tropical diseases is caused by flatworms belonging to the genus
Schistosoma.
Symptoms of
the parasitic infections include acute and chronic diseases, predisposition to cancer of the bladder, as well as pulmonary and
portal hypertension and in extreme cases, death. This study employs a deterministic climate-based model using differential
equations to investigate the impact of rainfall and temperature on the population dynamics of schistosomes in South Africa.
Numerical simulations of the system were done using mathematical models to examine the effect of climate variability on the
transmission dynamics of schistosomiasis. Results showed climate variability increases reproduction number of schistosomes
and snails. Hence, schistosomiasis transmission was suggested to be seasonal. Snails’ reproduction was found to peak during
summer and at the minimum during spring and autumn. So, sensitivity analysis showed reproductive number of schistosomes
is more sensitive to the reproduction rate of snails and the probability of infections. Finally, the model used suggested future
opportunity for modification and refinement for effective prediction of climate variability on the transmission dynamics of
schistosomiasis.
