Texas has been hit by an outbreak of the Zika virus, with the Centers for Disease Control and Prevention warning people in the state to stay home if they have symptoms and have recently traveled to a country with the virus.
A woman in Texas tested positive for the virus after being exposed to mosquitoes, and officials have also identified the city where the infection started as a possible site for a potential outbreak.
More than 2,000 people in Texas have tested positive with Zika, and there have been at least 13 confirmed cases.
In Dallas, officials have issued travel advisories for the city and counties of Irving and Plano, where the disease has been found.
The virus is transmitted via the bite of an infected Aedes aegypti mosquito.
Officials say mosquitoes are spreading the disease by breeding in contaminated drinking water.
In Texas, there have already been two cases of people with the Zika infection contracting the disease.
Two of those cases have been in Dallas.
The other two cases in Dallas were in the Dallas suburb of Irving, and the third case in the city of Plano was in a Dallas suburb.
Officials have not yet determined the cause of either of the cases, but said there was no indication the Zika strain was the same strain that has caused a spike in cases in the United States.
“There’s not any evidence that the virus is present in Plano,” Dallas County Judge Clay Jenkins said in a statement on Thursday.
Officials also said that if you are pregnant or have recently become pregnant, you should postpone getting pregnant.
There have been no new confirmed cases in Texas.
The CDC has issued two travel advisors for Dallas and Planos, saying that they are a “high-risk area” for the spread of the virus and the areas are also known to be a “major hot spot for mosquito breeding.”
