The Coronavirus has been in the news. As of January 2020, nearly 10,000 cases and over 200 deaths have occurred. It is thought to have originated in bats in the Wuhan area of China but has mutated enough to affect humans. Over 5,000 different viruses are known to exist but many more are discovered every month so this number is only the tip of the iceberg. There are cold viruses, Herpes, influenza or flu viruses, Hepatitis B, HIV viruses, and many others. There are no vaccines for most viruses.
