Zika Virus

Zika virus disease (Zika) is a disease caused by Zika virus that is spread to people primarily through the bite of an infected mosquito. The yellow fever mosquito (Aedes aegypti) is the most important vector, but the Asian tiger mosquito (Aedes albopictus) can also transmit the virus. The virus can also be spread from infected men and women to their sex partners or from an infected pregnant mother to her baby. Most people infected with Zika virus do not experience symptoms. About 1 in 5 will have a mild, self-limiting illness characterized by fever, rash, joint pain, and conjunctivitis (red eyes). There is no vaccine or specific treatment currently available for Zika.

In May 2015, the Pan American Health Organization (PAHO) issued an alert regarding the first confirmed Zika virus infection in Brazil and on Feb 1, 2016, the World Health Organization (WHO) declared Zika virus a public health emergency of international concern. Local transmission has now been reported in many other countries and territories in Latin America and the Caribbean. Zika virus likely will continue to spread to new areas.

Because established populations of Aedes aegypti mosquitoes are not present in our State, the risk of widespread local transmission of Zika virus occurring in Indiana is low. However, the Indiana State Department of Health is working on multiple fronts to be ready to prevent, detect and respond to cases of Zika infection. We hope that the information on this website is helpful in answering your questions about Zika virus.
