HOUSTON – Another case of the Zika virus has been confirmed in the Houston area.
A woman who traveled to Colombia in November has been diagnosed with Zika, according to the City of Houston Health Department. The woman is in her 50s or 60s.
"The symptoms were mild, joint aches, rash, fever, headache. With Zika, only one in five people will be asymptomatic, and most people aren't bad enough to go to the doctor." said Kathy Barton with the Houston Department of Health.
Another Harris County case was confirmed earlier this month in a patient who had also traveled to Latin America.
The Zika virus is spread by the Aedes mosquito and can't be passed from person to person. For now, only people who live in or travel to Latin America, Africa and Southeast Asia are at risk.
There is no known vaccine or medicine to treat the Zika virus.
According to Centers for Disease control, Zika virus mostly causes three to seven days of mild fever, rash, aches and red eyes. Most people don't have any symptoms and don't even know they have the virus.
However, it can be dangerous for pregnant women. The virus has been linked to birth defects that can cause a child's head or brain to develop abnormally small. The CDC is advising pregnant women to postpone trips to the countries affected.
The World Health Organization said Thursday the Americas could see 3 to 4 million cases of the Zika virus. Those still planning to travel to the affected countries are advised to take precautions by wearing bug spray, long sleeves, and if possible, stay indoors.
