Zika virus disease is an emerging disease currently being reported by 86 countries worldwide. Symptoms of Zika virus disease are similar to other viral infections such as dengue, and include fever, skin rashes, conjunctivitis, muscle and joint pain, malaise, and headache.

In India, the first outbreak was reported in Ahmedabad in January/February 2017 and second outbreak in July 2017 from Krishnagiri District in Tamilnadu.

The disease continues to be on disease surveillance radars of Union Health Ministry although it is no longer a Public Health Emergency of International Concern vide WHO notification since 18th November, 2016.

The first recorded outbreak of Zika virus disease was reported from the Island of Yap (Federated States of Micronesia) in 2007.

Zika virus is primarily transmitted by the bite of an infected mosquito from the Aedes genus, mainly Aedes aegypti, in tropical and subtropical regions. Aedes mosquitoes usually bite during the day, peaking during early morning and late afternoon/evening. This is the same mosquito that transmits dengue, chikungunya and yellow fever.

Zika virus is also transmitted from mother to fetus during pregnancy, through sexual contact, transfusion of blood and blood products, and organ transplantation.

There is no treatment available for Zika virus infection or its associated diseases.

Zika virus infection during pregnancy can cause infants to be born with microcephaly and other congenital malformations, known as congenital Zika syndrome. Infection with Zika virus is also associated with other complications of pregnancy including preterm birth and miscarriage.

An increased risk of neurologic complications is associated with Zika virus infection in adults and children, including Guillain-Barré syndrome, neuropathy and myelitis.
