A latest case of Zika virus has been reported in Dallas, Texas on Tuesday, but it does not seem to be brought by mosquito carrying virus but through sexual contact according to health officials.

The person who was affected with the virus has not been to any of the affected areas in the Latin Americas. But the partner happened to just returned from Venezuela.  This is the first case reported about a non-traveler contacting the disease in the mainland US. There have been seven other Zika cases in Texas but these are all related to foreign travel.

“It’s very rare but this is not new. We always looked at the point that this could be transmitted sexually.” said Zachary Thompson, director of the Dallas County Health and Human Services, in a report by Aljazeera.

According to Centers for Disease Control (CDC), the lab test has shown that the person who did not travel to any of the infected area has the signs of Zika infection.

CDC said that it will issue a new set of protective guidelines on the prevention of sexual transmission of the Zika virus. It will focus on the male sexual partners of the women.

Anne Schuchat, principal deputy director for CDC said “ We don’t believe this was spread through mosquito bites, but we do believe it was spread through a sexual contact.”

After this incident, male partners are advised to use condoms and women to avoid semen contact. Pregnant women has also been recommended to cancel foreign trips to the affected areas, mostly South America and the Caribbean.

Would be blood donors returning from any of the Zika-affected countries are advised to wait at least 28 day before donating blood.

On Monday, World Health Organization proclaimed an international emergency after a sudden influx of Zika cases in South American countries.

The decision came after the independent experts analysed the spike in the birth defect cases and increasing health anomalies in newly born babies. It has put the virus in the same category of Ebola, according to a report by BBC. 

Using insect repellent is strictly advised for Latin America and Caribbean visitors to avoid any mosquito bite.
