The Most Lethal Viruses Known To Mankind

HIV

Since the human immunodeficiency virus (HIV) was first formally recognized in the 1980s, it has killed more than thirty-six million individuals worldwide. Since then, powerful antiviral drugs have become available to help infected individuals live longer, though there is currently no cure for the condition. The virus tends to spread throughout low and middle-income countries, where ninety-five percent of new infections develop. The virus, which attacks the immune system, is spread through body fluid contact of infected persons by means of sexual intercourse or by sharing needles.
