How to Protect Yourself from Zika Virus

Posted: May 5th, 2016 at 12:00AM - by e7 Health

Zika is a virus that is spread primarily through the bite of an infected Aedes mosquito. Illness that results is typically mild and includes fever, rash, redness of the eyes, and joint pain that lasts for a few days to a week. Most people who contract Zika virus either do not know that they are sick, or only show mild symptoms that resolve on their own like a cold virus.

The primary concern with Zika virus is infection that occurs in pregnant women. Zika virus has been shown to cause a rare birth defect called microencephaly, as well as other severe brain defects in the developing fetus.

As of February 1, 2016, Zika has been declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization (WHO) with outbreaks occurring in areas of the Caribbean, Central America, South America, and the Pacific Islands, and the outbreak is still spreading. At the writing of this article, no cases of Zika virus have originated in the United States, although cases have appeared in the United States from travelers who have returned from Zika areas. The number of cases of Zika occurring in the United States due to recent travelers is expected to increase.

Although the spread of Zika virus is primarily through the bite of an infected mosquito, there have been reported cases of Zika virus spread through other modes of transmission. A man who becomes infected with Zika virus can pass on the disease through sexual contact. This can occur before symptoms begin, while symptoms are apparent, and after symptoms resolve. Wearing condoms can help prevent spread through sexual contact. Zika virus has also been found in blood transfusions, although none of these cases occurred in the United States.

Since there is currently no vaccine to protect you from the Zika virus, preventing mosquito bites is your main protection from the virus, and pregnant woman should avoid travel to Zika areas. If traveling to Zika areas, stay in accommodations with air conditioning and screens on windows and doors to avoid mosquitoes. Long sleeve and long pants should be worn, and insect repellent with DEET is recommended for exposed areas of skin.

Making an appointment at a credible travel medicine clinic with a travel clinician should be scheduled as soon as you know your itinerary when traveling to a possible Zika area.
