This Is Why New Diseases Keep Showing Up In The World

The world is becoming increasingly connected, and that includes the spread of disease. In the past, diseases would often stay isolated to certain areas of the world. But now, with international travel and trade, diseases can spread quickly to different parts of the globe.

This was demonstrated recently with the outbreak of Ebola in West Africa. The disease had never been seen in that region before, but it was able to spread rapidly due to the close contact between people and animals there. As a result, Ebola has now killed over 11,000 people in West Africa.

Similarly, the Zika virus has also been spreading rapidly around the world. The virus was first identified in 1947, but it wasn’t until 2015 that it began causing large outbreaks in Brazil and other countries in South America. Zika is now a global health concern, as it can cause birth defects in babies whose mothers are infected with the virus.

So why do new diseases keep appearing? One reason is that our population is growing and we’re coming into closer contact with other species of animals. This increases the chances that a disease will jump from an animal to a human.

Another reason is that we’re damaging the environment in ways that make it easier for diseases to spread. For example, deforestation can lead to more contact between humans and animals, as well as increasing the risk of flooding (which can spread waterborne diseases).

Finally, some new diseases are simply the result of mutations in existing bacteria or viruses. These mutations can make the diseases more virulent, or make them resistant to drugs.

Whatever the reason, it’s clear that new diseases are a growing problem in our world. And it’s one that we need to be prepared for.
