U.S. Officials Launch A Zika Travel Advisory For Southeast Asia

The difference between Southeast Asia’s “endemic” and Latin America and the Caribbean’s “epidemic”:

It’s important to note like the map above that there’s a difference between the Zika “epidemic” sweeping South and Central America and the Caribbean ― for which officials issued a travel alert ― and the lower-level “endemic” in Southeast Asia, for which officials issued a travel consideration

According to the CDC, Zika virus has been present in parts of Southeast Asia for years, and a large portion of the local population has likely developed immunity to the virus. Occasional Zika cases may occur, but it’s less likely that there will be a virus outbreak there than in virgin Zika territory. (Of course, travelers without such immunity may always be vulnerable.)

In comparison, Latin America and the Caribbean are experiencing a Zika epidemic. In those countries, the Aedes aegypti mosquito that primarily transmits the virus is present, and because there haven’t been reports of Zika virus in the area in the past, it’s unlikely that any local population has built up immunity. In Brazil, for example, where Zika virus spread rapidly this year, there have been 1,800 confirmed cases of Zika-related microcephaly.

Practically speaking, there’s not a big difference between the travel consideration and the travel warning. Both advise pregnant women or couples who are planning to become pregnant to consult a medical professional before traveling to an area with Zika virus, and to take steps to avoid mosquitos bites if they do decide to travel.

On September 30, the CDC changed its guidelines for men who have recently visited an active Zika outbreak area and want to conceive. Men should now wait at least six months following their last possible Zika exposure to conceive, up from an eight-week waiting period under the agency’s previous guidelines, regardless of whether or not they’ve experienced Zika symptoms.

For babies exposed to Zika virus in-utero, the effects can be devastating. Infants born with microcephaly typically have abnormally small heads and can have developmental disabilities. And even those born with normal-sized heads can have damage from the infection, including brain abnormalities and joint malformation linked to the virus, according to a report published in August in the journal Radiology.

The article has been updated to reflect the CDC’s latest Zika recommendations for men trying to conceive.
