In the aftermath of the Texas outbreak, the U.S. Centers for Disease Control and Prevention and the World Health Organization are pushing for the use of mosquito repellent.
In the weeks following the outbreak, there have been a number of deaths from mosquito-borne diseases and more than 50 reported cases of dengue fever in the United States.
On Wednesday, the head of the National Institutes of Health said there’s no reason to stop using repellents.
“If we don’t continue to be able to get people to use repellants, then I think it’s going to be a very, very bad thing,” said Dr. Stephen Silber, director of the NIH’s Office of Preparedness.
The CDC and WHO have issued guidelines for how people can protect themselves from the disease and are also urging pregnant women to get tested for the virus.
The American Academy of Pediatrics recently issued a statement saying that pregnant women should get tested regularly.
The CDC and the CDC-funded National Institute of Allergy and Infectious Diseases have both said that Zika is not transmitted through mosquito bites.
But as the virus continues to spread, the use and spread of repellant is increasingly a concern.
