Women who plan to get pregnant should take extra precautions against the Zika virus that has been linked to microcephaly. The mysterious pandemic infected more than 5,000 pregnant women in Colombia, making them at a higher risk of giving birth to infants with smaller brains.

The virus can spread from a pregnant woman to her fetus. Until the link could be confirmed, the Centers for Disease Control and Prevention (CDC) recommends that pregnant women in any trimester practice special precautions to prevent being infected with the virus.

Postpone Travel To Zika-Stricken Areas

CDC issued travel warnings to areas with reported Zika virus cases. Pregnant women or couples who plan to get pregnant are advised to avoid countries in South America, Pacific Islands, Central America, Mexico and the Caribbean. The health agency said that women who are trying to get pregnant and their partners should talk to their doctors before travelling to areas with Zika.

"At this time, we know that the best way to protect pregnant women from Zika is to delay travel to areas with ongoing Zika transmission," Dr. Denise J. Jamieson, Chief, Women's Health and Fertility Branch at CDC, said.

Know That Zika Can Be Transmitted Sexually

The virus that is known to be transmitted through mosquito bites can likely be transmitted through sexual intercourse. Health officials confirmed a case of Zika virus infection through sexual intercourse in Texas. A woman acquired the infection after having sexual intercourse with a man who recently traveled to Venezuela.

Practice Special Precautions To Prevent Mosquito Bites

There is still no known cure or vaccine for Zika virus. Health officials encourage travelers especially pregnant women to protect themselves from mosquito bites.

Travelers are advised to use mosquito-repellents with active ingredients and permethrin-treated clothing. They are also advised to cover exposed areas of the skin, sleep in air-conditioned screened rooms and use bed nets in areas exposed outdoors.

Be Aware Of Symptoms

Though most people infected with the virus do not manifest any signs of infection, pregnant women and those who plan to get pregnant should report if they experience any discomfort. Common signs and symptoms of the disease include fever, rash, red eyes, and joint pain. Other symptoms may include headache, pain behind the eyes, vomiting and muscle pain.
