Abstract:
There is a global rise in the emergence of infectious diseases and the enigmatic coronavirus disease 2019
(COVID-19) being the most recent one. It is ravaging the world with little understanding of its etiology and
factors affecting its transmission dynamics. Meanwhile, seasonal variations in weather are major factors
impacting infectious disease transmission patterns. Developing countries are likely to be most affected by
weather changes, largely because of challenges such as inadequate drainage and sewage management
systems, healthcare facilities, education, and funding to efficiently mitigate infectious diseases. In Nigeria,
weather conditions alternate between rainy and dry seasons. Conditions such as rainfall, flood, and
humidity have been reported to influence infectious disease transmission. Thus, understanding the impact
of weather changes in transmission dynamics and immune response to COVID 19 will help in preventive
measures and policy making to curtail its spread most especially in Nigeria as the rainy season fully sets
in.
