DALLAS (AP) — Health officials on Tuesday reported that a person in Texas has become infected with the Zika virus through sex in the first case of the illness being transmitted within the United States amid the current outbreak in Latin America.

The unidentified person had not traveled but had sex with a person who had returned from Venezuela and fallen ill with Zika, Dallas County health officials said. The U.S. Centers for Disease Control issued a statement saying lab tests confirmed the non-traveler was infected with Zika.

The virus, which has been linked to birth defects in the Americas, is primarily spread through mosquito bites, but investigators had been exploring the possibility it could be sexually transmitted. There was a report of a Colorado researcher who picked up the virus in Africa and apparently spread it to his wife back home in 2008, and it was found in one man’s semen in Tahiti.

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

The CDC says it will issue guidance in the coming days on prevention of sexual transmission of Zika virus, focusing on the male sexual partners of women who are or may be pregnant. The CDC has already recommended pregnant women postpone trips to more than two dozen countries with Zika outbreaks, mostly in Latin America and the Caribbean, including Venezuela. It also said other visitors should use insect repellent and take other precautions to prevent mosquito bites.

In the epidemic in Latin America and the Caribbean, the main villain identified so far is called Aedes aegypti — a species of mosquito that spreads other tropical diseases, including chikungunya and dengue fever. It is found in the southern United States, though no mosquito-borne transmission has been reported in the continental United States to date. There have been about 30 cases in the U.S. in the last year, all travelers who brought it into the country.

The World Health Organization on Monday declared a global emergency over the rapidly spreading Zika virus, saying it is an “extraordinary event” that poses a threat to the rest of the world. The declaration was made after an emergency meeting of independent experts called in response to a spike in babies born with brain defects and abnormally small heads in Brazil since the virus was first found there last year.

WHO officials say it could be six to nine months before science proves or disproves any connection between the virus and babies born with abnormally small heads.

The CDC said that in the recent Texas case, there’s no risk to a developing fetus.

Zika was first identified in 1947 in Uganda. It wasn’t believed to cause any serious effects until last year; about 80 percent of infected people never experience symptoms.

The most common symptoms are fever, rash, joint pain and red eyes. The illness is usually mild with symptoms lasting several days to a week. Symptoms usually start two days to a week after being bitten by an infected mosquito.

While Thompson told the television station that the case of sexual transmission is “a game-changer,” he added that he didn’t want people in Dallas County to overreact. Health officials and Thompson noted that sexual partners can protect themselves by using condoms to prevent spreading sexually transmitted infections.

Colombia: 3,100 Known Zika Cases in Pregnant Women

From VOA News

Colombian President Juan Manuel Santos said Saturday that more than 3,100 pregnant women in his country were infected with the mosquito-borne Zika virus.

But Santos, speaking on national television, said there was no evidence yet definitively linking the virus to the devastating fetal developmental disorder known as microcephaly, which leaves newborns with deformed skulls and underdeveloped brains.

There is no vaccine or treatment for the virus, and scientists have not yet established a direct link between Zika and a spike in birth deformities reported in neighboring Brazil.

In his address, Santos also said U.S. medical investigators would soon arrive in his country to help probe the virus, which he said had most likely infected more than 25,600 Colombians. On Friday, Colombian officials linked Zika to the paralyzing Guillain-Barre syndrome, which authorities said had killed at least three people in the country.

Santos’ address came as health officials in Brazil continued to voice strong suspicions that Zika has triggered a dramatic increase in microcephaly cases.

Brazil’s Ministry of Health on Wednesday reported 4,180 cases of Zika-related microcephaly since October, while just 147 such cases were recorded there in all of 2014.

The spike has triggered worldwide alarm and warnings for pregnant women to avoid traveling to Latin American and Caribbean countries where Zika cases have been reported.

Live virus in saliva, urine

On Friday, Brazilian health officials said they had found live samples of the Zika virus in saliva and urine samples — a discovery that prompted official warnings that casual kissing “increases the risk” of infection.

However, researcher Paulo Gadelha stopped short of calling for an “anti-kissing” policy, and said colleagues were still trying to determine whether body fluids could spread Zika to new patients.

Brazil entered the alcohol-fueled Carnival season Friday, a time when people commonly kiss strangers they meet at huge street parties.

In other recent developments, the World Health Organization has advised health personnel across the globe not to accept blood donations from people who recently returned from countries affected by the Zika virus.

For its part, the United Nations has urged the Latin American countries affected by Zika to provide women, men and adolescents access to comprehensive sexual and reproductive health services, including contraception and safe abortion services.

Zika has spread to 24 countries in Latin American and the Caribbean. There have been a small number of cases reported in the United States, and experts say they expect to see small outbreaks of Zika in several states bordering the Gulf of Mexico.

However, authorities do not expect widespread U.S. outbreaks, in part because human exposure to mosquitoes is limited in the United States by the widespread use of air conditioning and window screens.
