Information on Zika virus.

What we know

  • Zika is mainly spread by the bite of a mosquito infected with Aedes (Ae. Aegypti and Ae. Albopictus). These mosquitoes bite during the day and at night.
  • Zika can move from a pregnant woman to her fetus. Infection during pregnancy can cause certain birth defects.
    There is no vaccine or medication for Zika.
  • Local transmission of mosquito-borne Zika virus has been reported in the continental United States.

How Zika spreads

  • Through mosquito bites
  • From a pregnant woman to her fetus
  • Through sex
  • Through blood transfusion (very likely but not confirmed)

Zika symptoms

Many people infected with the Zika virus will have no symptoms or will only have mild symptoms. The most common symptoms of Zika are

  • Fever
  • Rash
  • Joint pain
  • Red eyes

Other symptoms include:

  • Muscle pain
  • Headache

Symptoms can last from several days to a week. People generally do not get sick enough to go to the hospital, and very rarely do they die from Zika. Once a person has been infected with Zika, they are likely to be protected from future infections.

Why Zika is risky for some people???

Zika during pregnancy can cause a brain birth defect called microcephaly and other serious brain defects. It is also related to other problems, such as miscarriage, fetal death and other birth defects. There has also been an increase in reports of Guillain-Barré syndrome, a rare disease of the nervous system, in areas affected by Zika.

How to prevent Zika???

There is no vaccine to prevent Zika. The best way to prevent mosquito-borne diseases is to protect yourself and your family from mosquito bites.

  • Clothing

    • Wear long-sleeved shirts and long pants.
    • Treat your clothes and equipment with permethrin or buy pre-treated items.
  • Insect repellent

    • Use the Environmental Protection Agency’s (EPA) registered insect repellents with one of the following active ingredients:
      DEET, picaridin, IR3535, lemon eucalyptus oil, the para-menthane diol, or 2-undecanone. Always follow the instructions on the product label.
    • When used as directed, these insect repellents are safe and effective even for pregnant and lactating women.
    • Do not use insect repellents on infants less than 2 months old.
    • Do not use products containing lemon eucalyptus or para-menthane-diol oil in children under 3 years of age.
  • At Home

    • Stay in air-conditioned places with window and door screens to keep mosquitoes out.
    • Take steps to control mosquitoes inside and outside your home.
    • The mosquito net can be used to cover babies under 2 months of age in carriers, strollers or cribs.
    • Sleep under a mosquito net if air-conditioned or protected rooms are not available or if you sleep outdoors.
  • Sexual transmission

    • Avoid Zika’s sexual transmission by using condoms or not having sex.
  • How Zika is diagnosed

    • Zika’s diagnosis is based on a person’s recent travel history, symptoms, and test results.
    • A blood or urine test can confirm an infection by Zika.
    • Zika’s symptoms are similar to other diseases spread through mosquito bites, such as dengue and chikungunya.
    • Your doctor or other health care provider may request tests for various types of infections.
  • What to do if you have Zika

    There is no specific medicine or vaccine for the Zika virus. Treating symptoms:

    • Get plenty of rest.
    • Drink fluids to prevent dehydration.
    • Take medications such as acetaminophen to reduce fever and pain.
    • Do not take aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs).
    • If you are taking medications for another medical condition, talk to your health care provider before taking any additional medications.
  • History of Zika

    The Zika virus was first discovered in 1947 and bears the name of the Zika Forest in Uganda. In 1952, the first human cases of Zika were detected and since then, Zika outbreaks have been reported in tropical Africa, Southeast Asia and the Pacific Islands. Zika shoots have probably occurred in many places. Prior to 2007, at least 14 cases of Zika had been documented, although other cases would probably have occurred and had not been reported. Because the symptoms of Zika are similar to those of many other diseases, many cases may not have been recognized.
