Mosquitoes that can transmit the Zika virus have been found to live in nearly all U.S. states, according to maps released this week by authorities trying to assess the public health threat.

The maps show the two breeds of virus-carrying mosquitoes, the yellow fever and the Asian tiger mosquito, can live in the nation's northernmost states of Michigan, New Hampshire, Washington state and Minnesota, according to the U.S. Centers for Disease Control and Prevention (CDC).

Zika Map June 8 2016 Zika, which has been linked to numerous cases of the birth defect microcephaly in Brazil, has spread rapidly in Latin America and the Caribbean. Microcephaly is marked by small head size that can lead to severe developmental problems in babies.

Map shows locations of reported cases of Zika Virus in the United States, according to the CDC, and is updated as new reports are made available.  As of this date, there are 132 cases in Florida, 8 in Palm Beach County.


CDC Awards $700,000 to Florida to Fight Zika Virus

Best Bug Sprays for Protection from Zika Virus

The Zika virus and other viruses are carried by certain mosquitoes. With lots of outdoor activities just around the corner, how do you protect yourself?

“DEET is definitely the most effective,” says dermatologist Dr. Brian Horvath.

Using a product containing 10 to 30 percent DEET will do the trick.

“The 10 percent will last around two hours. 30 percent will last about five hours,” he says. “Anything beyond 30 or 40 percent at the most doesn’t really have any increased effectiveness.”

DEET, the active ingredient in many insect repellents, has been around since the 1940s.

It is safe in pregnancy, and babies as young as two months old can use it. Just don’t eat it, and with young children, don’t put it on their hands.

“DEET is a neurotoxin, so if children were to ingest it, it could potentially affect their nervous system,” says Dr. Horvath.

For some, the smell and stickiness of DEET is a problem. There is an alternative, FDA approved in 2005, called picaridin.

“There are some studies that suggest it’s as effective, if not slightly more effective then DEET in certain situations,” says Dr. Horvath. “It’s a synthetic version of a pepper plant derivative. So some people think of it as being more a natural insect repellent, though it is still made in factories.”

What should you avoid? Essential oils like peppermint and rosemary, which have to be applied every 20 minutes to be effective.

One standard product isn’t such a glowing option.

“Citronella definitely is not very effective at preventing insect bites. Lemon oil of eucalyptus may be slightly better than some other essential oils. But still nowhere as effective as DEET or picaridin.”

These products are thought to work by creating a vapor barrier. So it’s important to apply sunscreen before bug spray, so as not to disrupt that barrier.
