What is important is to realise 85-90 % of all types of virus hepatitis heal completely. In a small proportion of people the healing gets delayed due to various factors, including super added infections. Only a small proportion in hepatitis B infection become carriers of the virus and again some have prolonged liver inflammation leading to liver damage. However, with improved and exciting technology physicians are able to make the correct diagnosis and prognosticate favourably and curative treatment to eradicate the virus altogether in almost all the countries. The answer to your question depends on the persistence of the infection and how able one remains, as chronic hepatitis can be physically disabling. If this is not the case there is no reason why one should not take part in international sporting events as long as the athlete is able to cope. Carrier state is also important to consider, as eradication treatment is currently available. I sincerely hope I have answered your question.
