US urges condom use or abstinence to avoid Zika virus

Miami: US health authorities on today urged people to use condoms or refrain from sex if they live in or have traveled to areas where the Zika virus is circulating.

The new interim guidelines from the US Centers from Disease Control are aimed at pregnant women and their partners, and at people of childbearing age who are concerned about Zika, a primarily mosquito-borne virus which has been linked to birth defects.

Earlier this week, US health officials confirmed the first case of sexually-transmitted Zika, involving a person who had traveled to Venezuela and infected a sexual partner in Texas upon return.

“Men with a pregnant sex partner who reside in or have traveled to an area of active Zika virus transmission and their pregnant sex partners should consistently and correctly use condoms during sex (vaginal, anal, or oral) or abstain from sexual activity for the duration of the pregnancy,” said the CDC in a statement.

“Consistent and correct use of latex condoms reduces the risk of sexual transmission of many infections, including those caused by other viruses.”

The CDC urged couples in which a partner is not pregnant to “consider using condoms consistently and correctly during sex or abstaining from sexual activity.”

But as to how long such measures should be followed, the agency could not say.

“The science is not clear on how long the risk should be avoided,” said the CDC statement, urging people to talk about testing with their healthcare providers.

“Research is now underway to answer this question as soon as possible.”

Meanwhile in Brazil, the nation’s top research institute said that Zika has been detected in urine and saliva, but added that there was no proof the virus could be transmitted through those fluids.

Asked during a conference call with reporters how likely it might be that Zika could spread through saliva and urine, Frieden said “we just have no data to inform that.”

Thousands of children in Brazil have been born with shrunken heads in the past year — a birth defect that could result from Zika infection, though a definitive cause has not yet been proven.

Until now, cases of Zika-linked microcephaly have been mainly in Brazil and in Hawaii, where a woman who had traveled to Brazil recently had a baby with the birth defect.
