Sweat may spread hepatitis B virus
Findings from a study of Olympic wrestlers indicate that hepatitis B virus is found in the sweat of infected individuals, and so sweating might be a way that the virus could be passed between participants in contact sports.
Bleeding wounds and mucous membranes have been implicated in hepatitis B transmission during contact sports, but until now no study had looked to see if sweat carries the virus.
Dr S Bereket-Yucel, from Celal Bayar University in Izmir, Turkey, tested for DNA of the hepatitis B virus in blood and sweat samples from 70 male Olympic wrestlers.
The results indicated that nine (13 per cent) of the wrestlers had the hepatitis B virus in their blood.
However, these were deemed "occult" infections because no antibodies to the virus were detected in any of the wrestlers, according to the investigators' report ahead of print by the British Journal of Sports Medicine.
In eight of the nine participants whose blood tested positive, DNA for hepatitis B was also detected in sweat.
Based on these results, "Evidence is emerging that the incidence of occult HBV in Olympic wrestling is higher than expected and that transmission of HBV may also occur through sweat," the researcher concludes.
"The advice of sports organisations about HBV testing should be changed," they recommend, "making it obligatory for all participants involved in contact sports and playing under adult rules to be vaccinated against hepatitis B."

We all have have protective immunity to HepB...which means there's nothing stopping us from challenging sweaty patients to impromptu wrestling matches (for fun and profit)!!!
This could have some pretty major ramifications for IMVS, I mean if they have trouble blood-testing all the med, dental and nursing students, then imagine the strain if they had to test all of the state's (contact)sportsmen and women as well.
A very interesting read! Cheers Amy
Great to see you all learning from the many sources of information that surround you. Thanks for sharing your findings with us Amy ,and Stuart, your case based scenario is quite amusing!!!
Thanks for making this blog both interesting and fun!!
