Americans don’t know much about Zika virus, poll shows
Florida, Texas most threatened states
WASHINGTON — Americans don’t know a lot about the Zika virus that is linked to birth defects and creeping steadily closer, according to a new poll that found about 4 in 10 say they’ve heard little to nothing about the mosquitoborne threat.
Even among people who have been following the Zika saga at least a little, many aren’t sure whether there’s a vaccine or treatment — not yet — or if there’s any way the virus can spread other than through mosquito bites.
Still, with mosquito season fast approaching, more than half of the population supports a variety of efforts to control summer swarms — from spraying pesticides to releasing genetically modified mosquitoes, says the poll conducted by The Associated Press-NORC Center for Public Affairs Research.
The government is considering a field trial in the Florida Keys of genetically altered male mosquitoes, which don’t bite. When they mate with wild females, the offspring quickly die. The poll found 56 percent of people would support introducing such mosquitoes into areas affected by Zika.
“I think it’s kind of the wave of the future, to be honest,” said Janis Maney, 63, of Pensacola, Fla., who sees mosquitoes nearly year-round in her warm climate. She’s open to “anything that would control those little buggers.”
The Zika virus has exploded throughout Latin America and the Caribbean. While adults typically suffer mild, if any, symptoms, there’s an increasingly strong link between infections in pregnant women and fetal death and devastating birth defects — babies born with small heads that signal a damaged brain.
U.S. health officials are warning pregnant women and those attempting to conceive to avoid traveling to Zika-affected areas. More than 300 cases of Zika have been diagnosed in the U.S., all so far associated with travel.
While experts don’t expect an epidemic here, they worry that small clusters of cases are likely, particularly in Florida or Texas, if the insects bite returning travelers and then someone else.
“We have only weeks to prepare before the mosquitoes, and perhaps the virus, get ahead of us,” said Dr. Edward McCabe of the March of Dimes.
Leah Zeleski, 27, of Lincoln, Neb., said she won’t travel too far south this summer. A nursing student, Zeleski calls this a “very scary” time for women of childbearing age and wonders what scientists will discover next about Zika’s risks, unknown until the current outbreak began in Brazil last year.
Zeleski said she’ll wear insect repellent and cover up during mosquito season.
The AP-NORC Center poll found that among people who’ve heard about Zika, 90 percent know mosquitoes can spread it but there are some other key gaps in knowledge:
About 1 in 5 couldn’t say whether Zika was linked to birth defects.
Zika also sometimes spreads through sexual intercourse, but 14 percent wrongly thought it couldn’t, and another 29 percent said they didn’t know. That’s worrisome, because the Centers for Disease Control and Prevention says men who’ve traveled to Zika-affected areas either should use condoms with their pregnant partners or avoid sex until the baby’s born.
More than half didn’t know if there was a vaccine or treatment for Zika — there is not — or a diagnostic test. There are tests but they’re not perfect, and they’re being used primarily with pregnant women.
