According to the CDC, many of these cases are in pregnant women.
“These new reports suggest sexual transmission may be a more likely means of transmission for Zika virus than previously considered,” the CDC said.
Two cases are in women whose only possible risk is sexual contact with another person with the virus after coming home from an infected area.
An additional four women are suspected to have the virus – lab tests are pending. There are eight other potential cases under investigation.
The CDC has not said which states these women live in. They are working with state and health officials to investigate.
The CDC is urging people to follow issued guidelines of abstinence or condom use who’s partners have been to an infected area. It also issued a Health Action Network Alert.
