Between 1 January and 31 December 2024, a cumulative total of 151 Zika virus disease (ZVD) cases were reported from three states in India (Gujarat, Karnataka, and Maharashtra states). Maharashtra State reported a cumulative total of 140 ZVD cases through the Integrated Disease Surveillance Programme (IDSP). Additionally, Karnataka and Gujarat states reported ten and one cases, respectively, in 2024. Underreporting is likely, given the mild to asymptomatic course of infection in most cases.
As of 31 December 2024, no cases of microcephaly and/or Guillain-Barre syndrome (GBS) associated with this outbreak have been reported.
Zika is endemic in India. According CDC, the transmission risk is increased in Maharashtra state. Please note that the Zika virus can also be transmitted sexually!
Prevention: Optimal mosquito protection 24/7: during the day against Zika, dengue and other arboviruses, at dusk and at night against malaria.
When travelling to areas with increased Zika transmission, as is now the case in the state of Maharashtra, India, the Swiss Expert Committee for Travel Medicine recommends using a condom/femidom during the trip and for at least 2 months after returning home to prevent possible sexual transmission of the virus.
Due to the risk of malformations in the unborn child, pregnant women are currently advised not to travel to the state of Maharashtra in India. If travelling is absolutely necessary, it is recommended that you speak to a specialist in travel medicine before departure.
Women planning to become pregnant should wait at least 2 months after their return (or that of their partner) from India before starting family planning. In the case of medically assisted reproduction, this period should be extended to at least 3 months. Please also read the Zika information sheet, especially if you are pregnant or if you or your partner are planning a pregnancy.
