Hepatitis B found in wrestlers’ sweat

Some Olympic-level wrestlers have traces of the hepatitis B virus in their blood and sweat and they may risk spreading it to their teammates and opponents, a study suggests.

Researchers in Turkey obtained blood and perspiration from 70 male wrestlers competing in a Turkish National Championship. Nine had small but detectable amounts of hepatitis B virus in their blood, eight had it in their sweat, and one man had it in both.
