HIV
a '9' on Richter Scale of Viral Diseases [Nature
2001;412:271]: This is a report in the "Commentary" section
which presents a virologic "Richter scale," ranking viruses
on a scale in which 10 represents all deaths from infectious diseases
due to viral infections in 1999. HIV registers 9.1. Other rankings
are: hepatitis B and hepatitis C-8.6, measles-8.3, dengue-5.8, polio-4.7,
Ebola-2.8, hantavirus-1.3 and West Nile virus-0.3. The only virus
that comes close to HIV historically is Spanish influenza, which
killed over 20 million in 1918-19, and smallpox.
