Highest rates of infection were observed in non-Qatari nationals, particularly those of African origin. There was no clear trend with age and immunity level, but cycling was found to have significantly higher rates of Hepatitis B infection. There was no difference in infection rates between contact and non-contact sports.CONCLUSION: The risk of Hepatitis B transmission in football was assessed at one transmission in 12.5 million football matches, but the high rate of non-immunity suggests that sportsmen competing in Qatar are at elevated risk of Hepatitis B infection should they be exposed. This imbalance of infection and immunity rates requires further investigation and urgent redress.
