Hantavirus ‘can pose sexual transmission risk years after infection’, experts say
Spanish health ministry provides update on cruise ship hit by hantavirus
A peer-reviewed study revealed that hantavirus genetic material persisted in a 55-year-old man’s semen for 71 months (nearly six years) after his initial infection.
This finding, from scientists at Switzerland’s Spiez Laboratory, suggests the male reproductive tract may act as a reservoir for the virus, indicating a potential for sexual transmission years after initial infection.
Hantavirus typically spreads through rodent exposure and can cause a severe illness with a high fatality rate, making its long-term persistence a significant public health concern.
Experts are now advocating for the World Health Organisation (WHO) to revise its guidance, recommending extensive safe-sex advice for male patients, akin to protocols for Ebola survivors.
The current WHO advice suggests a 42-day quarantine for high-risk contacts, but new research implies a need for longer-term monitoring and precautions, such as condom use.
