  A virus with a strange-sounding name has been around for a long time but only in parts of the world. Now, chikungunya is traveling the world. (5)Health officials first identified chikungunya in 1952 in East Africa. Chikungunya starts like the flu. Sufferers get fever, and head and muscle pain. Some people also develop a skin condition. But (6)what separates chikungunya from other viruses is the extreme pain and swelling in the joints of hands and feet. Doctor Scott Weaver is director of the Institute for Human Infections and Immunity at the University of Texas in the United States. He explains how this virus differs from other flu-like sicknesses. "It starts off like many other flu-like infectious diseases with fever and headache and body aches. But what distinguishes it from most others is that the pain is focused on the small joints like the hands, the wrists and the ankles. And that’s accompanied by swelling. And the combination of swelling and pain can leave people pretty severely incapacitated." (7) Chikungunya rarely kills. But it can incapacitate people who get it, meaning they can barely move.
