The CDC currently recommends that men who have traveled to a Zika-active region either use condoms or abstain from sex for at least 6 months. But that guideline is based on data showing that genetic traces of Zika virus can be found in semen 180 days after infection.
Vertical transmission of ZIKV in humans has been confirmed. Furthermore, there have been reports of ZIKV infection in field-collected eggs, larvae and adult mosquitoes, which implies that ZIKV can also be vertically transmitted in mosquito vectors.
What is the contagious period for a Zika virus infection? Zika virus can remain in semen (up to 93 days) longer than in other body fluids such as vaginal fluids, urine, or blood.
The best protection from Zika virus is preventing mosquito bites indoors and outdoors, especially from sunrise to sunset when mosquitos are most active. Such measures include: Use mosquito repellent in accordance with the instructions indicated on the product label. Wearing long-sleeved shirts and long trousers.
When symptoms do occur, they usually begin two to seven days after a person is bitten by an infected mosquito. Signs and symptoms of the Zika virus most commonly include: Mild fever. Rash.
Zika Can Be Passed Through SexSex includes vaginal, anal, and oral sex and the sharing of sex toys. Zika can be passed through sex even in a committed relationship. The timeframes that men and women can pass Zika through sex are different because Zika virus can stay in semen longer than in other body fluids.
Condoms can protect against sexually transmitted Zika.
As of January 2020, there are no areas with a current Zika outbreak. If you are trying to get pregnant, or your partner is trying to get pregnant, then you may want to reconsider travel because of the virus's link to birth defects and complications.
As the first babies born with brain damage from the Zika epidemic become 2-year-olds, the most severely affected are falling further behind in their development and will require a lifetime of care, according to a study published Thursday by the Centers for Disease Control and Prevention.
Women should wait at least 2 months after travel (or 2 months after symptoms started if they get sick) before trying to get pregnant. The waiting period is longer for men because Zika stays in semen longer than in other body fluids.
The overall estimated incidence of confirmed and presumptive Zika virus disease was 844 cases per 100,000 residents. The highest incidences were in persons aged 20–29 years (1,150 cases per 100,000 residents), and 10–19 years (1,111 per 100,000) (Figure 1) when pregnant women were included.
Many people infected with Zika virus won't have symptoms or will only have mild symptoms. A blood or urine test can confirm Zika infection.
The infection, known as Zika fever or Zika virus disease, often causes no or only mild symptoms, similar to a very mild form of dengue fever. While there is no specific treatment, paracetamol (acetaminophen) and rest may help with the symptoms.

If I traveled, should I get tested for Zika? If you have traveled to an area of Zika risk, you can be tested. A test called a RT-PCR will check for the virus in your blood and urine if it has been 2 weeks or less since you may have been exposed to Zika.
Brain abnormalities associated with congenital Zika syndrome have been identified by ultrasound in the second and third trimesters in published case reports. CDC previously recommended serial ultrasounds every 3-4 weeks for women exposed during pregnancy with laboratory evidence of Zika virus infection.
The most common signs and symptoms include:
- Headache.
- Fever (You may or may not have a fever if you have Zika.)
- Joint or muscle pain.
- Pink eye (also called conjunctivitis)
- Rash.
Currently, there is no cure or specific treatment for Zika virus. Treatment aims to ease symptoms and reduce the risk of complications while the person recovers.
This is the same mosquito that transmits dengue, chikungunya and yellow fever. Zika virus is also transmitted from mother to fetus during pregnancy, through sexual contact, transfusion of blood and blood products, and organ transplantation.
Because there is no vaccine or medicine for Zika, travelers should take steps to prevent getting Zika during travel.
