Today’s announcement marks a total of five travel-related Zika cases that have been reported in Fresno County, said Leticia Berber, an educator with the Fresno County Department of Public Health.

The woman contracted the disease from a man who in turn got it during travel to another country, Berber said. While most people infected with Zika do not experience symptoms, it can cause serious birth defects of the brain in fetuses and infants.

Berber said the infected woman is not pregnant.

The virus spreads primarily through the bite of an infected Aedes species mosquito, but can also be spread through unprotected sex with a Zika-infected person.

The symptoms of infection can include a rash, fever, joint pain and redness of the eyes.

Health officials recommend sexually active people who have traveled to areas where the virus is in circulation should use condoms or other barrier methods during sex to avoid transmission. Men are advised to wait a minimum of six months to attempt conception of a child after Zika exposure, and women should wait a minimum of eight weeks before becoming pregnant.

The Fresno County Department of Public Health encourages residents to protect themselves while traveling to areas where the virus circulates, which includes countries such as Mexico and Brazil, Berber said.

Fresno County announced its first travel-associated Zika case in July 2016 of an adult female.

Recommended precautions include:

• Use of an insect repellent registered by the Environmental Protection Agency containing one of the following ingredients: DEET, picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol, or 2-undecanone

• Wearing long-sleeved shirts and long pants

• Abstaining from sex or using condoms every time you have sex

• Using screens on windows and doors

• Using air conditioning when available

• Removing standing water inside and outside where mosquitoes can lay eggs
