ZIKA: W.H.O. Clarifies Advice on Sex and Pregnancy in Zika Regions. “A spokeswoman said the agency made the announcement to clear up earlier confusion over whether it was advising women to avoid pregnancy during the epidemic. The W.H.O. is not offering such advice, although, she conceded, officials did appear to have said as much in June. The W.H.O. also suggested that men and women who visit and return from areas with mosquito-borne Zika transmission practice protected sex or abstinence for six months. The advice to wait that long — instead of eight weeks, the previous limit — is based on new evidence about the persistence of the virus in semen.”

This just gets better and better.
