Sun Rays Suppress Spread of Chickenpox

A virologist at St George's Hospital, University of London suggests that sunrays (UV light) suppresses the spread of chickenpox to other people. He relates this phenomenon to the disease spreading less in tropical areas.The virus responsible for chickenpox is varicella-zoster virus(the herpes virus) is now believed to die in presence of sunlight.

Citing his study in Virology Journal, Rice writes about how "chickenpox is much less common in parts of the world with high levels of UV rays compared with places where the levels are low, and why (that) in temperate zones, the disease peaks in winter and spring, when UV rays are at their lowest."
