Examination of the prevalence of viral diseases shows that the spread of these diseases follows a climatic pattern. Influenza, for example, is one of these diseases whose pattern of prevalence is seasonal and depends on air temperature in some parts of the world, although in the tropics these changes are less. Numerous mechanisms have been proposed to explain these changes, but our understanding of this phenomenon remains insufficient. Due to the viral nature of the disease, the corona spread is expected to follow a specific climatic pattern.
