Information on Active Investigations

When a local case of Zika virus is confirmed through laboratory testing, the department conducts a thorough investigation around the case to determine if additional people are infected. The department interviews and tests close contacts and community members around the case. Knowing if additional people are infected helps the department determine if there is a zone where mosquitoes are transmitting the virus. Not every case results in a designation of active transmission in an area. In some instances, a case of Zika is an isolated incident with no additional people infected.

Zika fever is acquired through the bite of an infected mosquito, including the same mosquitoes that can transmit dengue and chikungunya. Perinatal and sexual transmission have also been reported.

CDC - Effective condom use to prevent sexual transmission

Only about 1 in 5 people infected with Zika virus are symptomatic. Zika fever is a mild illness. Severe disease requiring hospitalization is uncommon. Signs and symptoms of Zika fever may include: acute onset of low-grade fever, rash, joint pain, conjunctivitis (reddening of eye), body aches, headache, eye pain, and vomiting. Treatment is symptomatic since there is no specific treatment against the virus. Illness typically resolves within a week.

The Ministry of Health of Brazil has reported an increase in the numbers of newborns with microcephaly in areas experiencing Zika virus outbreaks. Further studies are being conducted to investigate this concern. There are many causes of microcephaly in babies, including genetic abnormalities, environmental factors, and some infections acquired during pregnancy.

Mosquito Bite Protection for Overseas Travelers / Spanish

Travelers to a tropical or sub-tropical area (Africa, Asia, Caribbean, Mexico, Central and South America), can protect themselves from Zika and other mosquito-borne diseases by following these prevention suggestions:

• Use insect repellant with any of the following active ingredients
  • DEET (up to 30%)
  • Picaridin
  • Oil of lemon eucalyptus
  • Para-menthane diol
  • IR3535
  • Always follow product label instructions and make sure repellent is age-appropriate.
  • It is safe for pregnant or nursing women to use EPA-approved repellants if applied according to package label instructions.
  • Apply repellent on bare skin or clothing, not under clothing.

• Cover skin with long-sleeved shirts and long pants
  • Apply a permethrin repellent directly to clothing or purchase pre-treated clothing. Follow the manufacturer’s directions and do not apply directly to the skin.

•  Keep mosquitoes out of hotel rooms
  • Choose a hotel or lodging with air conditioning or screens on windows and doors.
  • Sleep under a mosquito bed net when outside or in a room that is not screened.
