Answer:
Essay title:
<em><u>What has really changed with the diseases?</u></em>
Explanation:
Some of the diseases that existed in the past still exist today, we can mention some examples such as:
tuberculosis, yellow fever and leprosy.
In the past, these diseases were difficult to control and as there was little scientific knowledge about the mechanism of action and spread of the disease, this caused these diseases to spread more rapidly. Today, thanks to advances in science, the mechanism of disease spread is already known, and it is also possible to take preventive measures more quickly to prevent their spread.
To make an analysis we can compare the yellow fever disease and the coronavirus, both diseases have some similarities, for example they were imported, the yellow fever from Africa and the Coronavirus from Asia, both diseases had a rapid spread, but as differences we can say that today we have a greater professional and scientific knowledge that allowed us to quickly create vaccines to prevent coronavirus, while with yellow fever the world had to wait until 1937 so that a vaccine against the yellow fever virus could be created.
