- The US government’s Centre for Disease Control and Prevention (CDC) has modified its advisory against travelling to India. In 2018, CDC had issued the advisory after zika cases were reported in Rajasthan and Madhya Pradesh.
- The travel advisory stated that India has an ongoing outbreak of the disease in Rajasthan and its surrounding states. It also cautioned pregnant women and women who are planning for pregnancy not to travel to areas with ongoing zika outbreaks.
- The status of India in the Zika virus alert for travellers has been changed from “ongoing outbreak” to “current or past transmission but no current outbreak”. The modification comes after Union Health Ministry, in January, had urged the US government to change or modify the travel advisory.
- Zika virus disease is caused by a virus transmitted primarily by Aedes mosquitoes. Additionally, infected people can transmit Zika through transfer of body fluids including sexual intercourse.
