Wrestlers should be vaccinated against hepatitis B Photo: David Monniaux, Wikipedia
Reading Hepatitis B could possibly be transmitted in a previously unknown way: Researchers have detected the liver-damaging virus in the sweat of wrestlers and therefore require a mandatory vaccination for all martial artists. Selda Bercet-Yücel examined seventy athletes who participated in the Turkish championship in the Olympic wrestling. In nine athletes, she diagnosed a hidden form of the viral disease, the so-called occult hepatitis B infection, and in eight of them she was able to detect hereditary substance in sweat.

Although it has not been proven that hepatitis B can actually be transmitted via sweat, researchers at least do not exclude this possibility. In sports with body contact such as rugby, boxing or wrestling open wounds are not uncommon. About these or about mucous membranes, viruses contained in the sweat could possibly be transmitted, write the scientists.

In another infectious disease, the AIDS immunodeficiency disease, the international boxing and wrestling federations have decided to subject all athletes to regular mandatory tests in the future. In these sports should also be tested for hepatitis B, and the athletes should be vaccinated against the virus at the beginning of their career, Bercet-Yücel suggests. Because the hepatitis B virus is much easier to transfer, because it is more stable and occurs in blood in higher concentrations. Hepatitis B is the world's most common virus infection: over 350 million people are chronically infected with the virus. The virus against which a vaccine exists attacks the liver and can cause liver cirrhosis.
