DOVER, DE (Dec. 20, 2016) - Many people like to plan getaways to warmer climates during the holidays to escape the chilly northeast coast weather. If you're one of them, the Division of Public Health (DPH) reminds you that Zika is still active in many south and central American countries, southeast Florida and even Southeast Asia. Since there is no vaccine for Zika virus yet, stopping a mosquito bite, and practicing safer sex if you are involved with someone who could be exposed, is still the best protection against the disease.

DPH confirmed last week that Delaware Zika cases are now at 17. The most recently announced case involves a female resident of Sussex County, for whom pregnancy is not at issue. All cases were caused by mosquito bites while traveling abroad. All but one of the Delaware Zika cases are in adults and none is pregnant. Of the 17 Delaware cases, nine are in New Castle County, three are in Kent County and five are in Sussex counties.

Anyone who is traveling abroad and gets bitten by a mosquito carrying Zika virus or, has unprotected sex with someone who has been exposed to the virus, including a local in that country, could get the disease. That same Delawarean could return home and spread it here through sexual activity or during pregnancy. To prevent spreading Zika during sexual activity, barrier methods (condoms, dental dams) should be used.

Women who are trying to become pregnant and have been diagnosed with Zika virus or have symptoms of Zika, should wait at least eight weeks after symptoms first appeared before trying to conceive. Men who have been diagnosed with Zika virus or have symptoms are advised to wait at least six months after symptoms first appeared before having vaginal, oral, or anal unprotected sex.

For an updated list of countries impacted by Zika visit: The most recent CDC data (Dec. 14, 2016) shows that 4,617 people in the U.S. and DC have been infected with Zika virus, as have another 34,268 in the U.S. Territories.

"While mosquito season is over in Delaware, Zika remains a constant threat in other countries that are favorite travel spots for vacationers," said DPH Director Dr. Karyl Rattay. "It's important to constantly remind people of the need to protect themselves while traveling and that pregnant women should avoid countries where Zika transmission is active." Dr. Rattay stressed that pregnant women and their sexual partners need to be tested if they recently traveled to Zika affected areas. If the sexual partner has confirmed Zika, the couple should abstain from sex or use condoms and other barrier methods until the baby is born.

To reduce the risk of mosquito bites while traveling, use Environmental Protection Agency-registered insect repellents; stay in places with air conditioning or that use window or door screens to keep mosquitoes outside; sleep under a mosquito bed net if you are outside and not able to protect yourself from mosquitoes; treat clothing and gear with permethrin available in pharmacies or purchase permethrin-treated items; and wear long-sleeved shirts and long pants.

Zika is a generally mild illness caused by a virus primarily transmitted through the bite of infected Aedes mosquitoes. About one in five people infected with the virus develop the disease, and most people who are infected do not develop symptoms. The most common symptoms of Zika virus infection are fever, rash, joint pain, and conjunctivitis (red eyes). However, while it is often mild, Zika has been linked to serious birth defects in infants whose mothers were infected during the pregnancy and rare but serious health complications in adults.
