Bacteriology:

How might climate change and over population impact the incidence of a disease? Use a specific example to illustrate your answer.

Answer 1

Question

The climate change play an important role in the incidence of diseases, specifically the incidence of infectious disease caused by harmful microbes. The different microbe need specific climate in which they could grow more easily, increase their population and spread from one organism to another. For example, the warmer , wetter climatic conditions brought by climate change make easy for the transmission of various diseases like dengue fever and chikungunaya.

The other factor increases the incidence of disease is over-population. This is because increased number of individuals increases the rate of transmission as microbes have high chance to get pass or transmit from one individual to another.

For example, malaria disease spread very fast as temperature increases, rainfall and humidity increases. This is because mosquitoes that cause malaria have high proliferation rate at these climatic conditions. Also, malaria is having high frequency in the countries like African countries where population is high as mosquitoes get human host in high frequency to transmit the disease.
