Solution
Diseases spread on a large scale during periods of heavy rainfall and floods because it provides the optimum conditions for the growth of vectors that transmit diseases. After heavy rainfall and floods, water gets accumulated at places and acts as breeding grounds for mosquitoes and other vectors. These vectors lead to transmission of the microorganisms to their host and result in the development of disease.
For example, malaria is caused by a virus that is transmitted by a mosquito.
