DALLAS – Initially, the Zika virus was considered a “mild” disease, but public health officials have become increasingly concerned that pregnant women who contract Zika can pass the virus to their unborn babies, said Texas A&M AgriLife Extension Service entomologists.

“The main cause for concern is the possibility the Zika virus may cause microcephaly, a condition where the fetal brain and head do not fully develop and reach normal size,” said Dr. Mike Merchant, AgriLife Extension urban entomologist, Dallas. “Currently, there is no vaccine or preventive treatment for Zika, nor is there a cure for microcephaly.”

To help instruct women about Zika, how it is transmitted and how to reduce the risk of contracting it, Merchant and Dr. Sonja Swiger, AgriLife veterinary entomologist, Stephenville, have developed an informative fact sheet.

The fact sheet can be found on the Texas A&M AgriLife Extension Bookstore website at, Insects in the City website at and Livestock Veterinary Emtomology website at or .

“The best-known carrier or vector of the Zika virus is the yellow fever mosquito, Aedes aegypti,” Merchant said. “The Asian tiger mosquito, Aedes albopictus, can also carry the Zika virus. Both these mosquitoes are common in Texas and are found in the same communities.”

Swiger said currently the greatest risk to young families occurs when pregnant women or women who may become pregnant travel to one of the countries in the southern Pacific or Latin America where Zika is present.

“The Centers for Disease Control and Prevention is advising pregnant women who are thinking about traveling to one of these countries to cancel their plans,” Swiger said. “If you travel to an area of infection and contract Zika, you remain infectious to others for about a week. Traveling to an area of infection is not worth risking the life of your unborn baby, so travel plans should be adjusted in order to protect your baby.”

Merchant and Swiger also noted Zika can be transmitted sexually by men to their partners.

“To date, this is the only way local transmission of Zika is known to have occurred in the United States,” Merchant said. “In countries where mosquitoes spread Zika, sexual transmission of the virus is not easily recordable but considered to be less frequent than from a mosquito bite.”

The Centers for Disease Control has also recommended women with confirmed cases of Zika or those who have visited epidemic areas, wait at least eight weeks before trying to get pregnant.

“Additionally, men with confirmed cases of Zika or who have visited epidemic areas are advised to wait at least six months after their trip or symptoms begin before having unprotected sex,” Swiger said. “These recommendations are based on current knowledge of how long the Zika virus remains active in the body and in the semen.”

“Remember that 80 percent of the people who are infected with Zika don’t feel ill or demonstrate any of the symptoms such as joint pain, fever, itchy eyes or rash,” Merchant said. “Just because you feel well, it doesn’t mean you have avoided infection.”
