The topic of this site is medical information about viral and bacterial infections.
Viruses are genetic code information, that is capsulated in protein. They are very tiny and small, much smaller than bacterias. They are a kind of parasitic living. In fact not really a living beeing. Because they are not much more than genetic information. Without a living cell, they can't replicate themselves.
To prevent infections, it is wise knowing viral infections better.
The word Virus is taken from Latin. It means poison or toxin. Of course, a Virus is an infectious micro agent. Itself it is nothing more than genetic information capsulated in protein. Without a living cell, it can't "live" or replicate itself.
But there are many more Viruses like, Bornea Disease, Dengue Fever, Lassa Fever, Yellow Fever, Rabies, Herpes Simplex, Infectious mononucleosis, Marburg Virus, Roseola Virus, Tick-borne Meningoencephalitis and many more.
