Why are viruses more common here?
The population density of continents is one of the main causes of this. The likelihood of people coming into contact with animals rises with population density. The likelihood of illnesses spreading increases significantly under such circumstances. Approximately 60% of the world's population currently resides in Asia and the Pacific. As a result of population growth, direct interactions between humans and animals have begun. There are numerous harmful viruses in these wild animals that have not yet been identified. Consider bats, a little species that is always present and comes in over 100 different types. These viruses spread from person to person to infect people.
Experiencing changes in these domains is another important factor. Researchers have shown that similar shifts occurred in britain during the 18th and 19th centuries as a result of industrialization. During that era, britain faced numerous illnesses, including cholera and typhoid.
In Africa, cases of human illness from animal-borne infections date back hundreds of years. But in the past, this virus was limited to Africa because there were no transit options. In addition, inadequate health care and social instability are significant factors that contribute to the spread of these illnesses.
