CHICAGO (Reuters) - The Zika virus may be particularly adept at entrenching itself in parts of the body that are shielded from the immune system, making it harder to fight off and possibly lengthening the timeframe in which it can be transmitted, top U.S. experts said on Friday.
Researchers reported that Zika virus can be detected in semen for 62 days after a person is infected, adding to evidence of the virus’s presence in foetal brain tissue, placenta and amniotic fluid. Their work is part of an international race to understand the risks associated with Zika, a rapidly spreading mosquito-borne virus thought to be linked to thousands of cases of birth defects in Brazil.
