With this article, we are starting out on a series about viruses.
We all know something about them. Have you ever had a cold? Of course! How about chicken pox? Warts? Hepatitis?
If you’ve had any of these (and many, many more), then you have come up against one of our smallest, and the strongest, of our disease enemies—the viruses.
The word “virus” comes from Latin, and it means slimy liquid, stenchy, poison. And that is strange because viruses don’t have any of these characteristics at all.
