Malaria is characterized by “uncontrollable shaking” while “Yellow fever is characterized by weakness and dizziness”.(Pinheiro & Rosa Ap, 1978) C. Why are yellow fever and malaria not threats at present in North America? The reason that both of these viruses are no longer present in United States of America is because of the fact that government has initiated vaccination programs, which has made it possible to eradicate both these diseases from the U.S and there is “strict laws for vaccination of immigrants and travelers coming from countries where malaria is still present and also for tourists travelling from US to abroad”.

To decrease the ratio of sick people, it is necessary that people take vaccination, live and eat hygienically and as the saying goes, “Prevention is better than cure” should be given priority. Looking at the concept of warm and cold weather, people in cold countries are less sick as compared to people warm countries i.e. India, China, and Pakistan etc. It’s not about how less people get sick depending on the climate it’s about the precaution and prevention they do. Most of us spend winter trying to stay heated, but a little bit of experience of cold weather may not be such a bad factor.
