Zika virus is primarily spread to people through mosquito bites. The virus can be spread from mother to child. Spread of the virus through blood transfusion and sexual contact has also been reported.
Most people infected with the virus have mild or no symptoms. For those who do develop symptoms, illness is generally mild and typically lasts a few days to a week. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes).
Severe disease requiring hospitalization is uncommon and fatalities are rare. An increase in Guillain-Barré syndrome was noted during an outbreak of Zika virus in French Polynesia in 2014. An increase in microcephaly was noted during an outbreak of Zika virus in Brazil in 2015.

April 18, 2017 - Weekly Texas Data for National Zika Pregnancy Registry
Texas has reported 250 individuals into the CDC’s Zika Pregnancy Registry. The registry includes pregnant women with laboratory evidence of Zika infection and their infants, regardless of laboratory evidence. Texas provides data to the Zika Pregnancy Registry weekly.
The registry casts a wider net – beyond reported Zika cases – to track and follow pregnancies that may have been impacted by Zika.
Who Texas Counts for the CDC Registry
The registry counts any pregnant woman or newborn who receives care in Texas and who also meets requirements stated above.
Who Texas Counts as Zika Pregnancy Case
To be reported as a Zika disease case in pregnancy, the pregnant woman has to have had one or more clinical sign or symptom compatible with Zika and also have a positive Zika test result.
Note: Pregnancy Registry counts will be updated weekly. No other details will be provided about Texas pregnancies reported to the CDC due to privacy concerns and that it is not warranted from a public health standpoint.
