Zika virus disease in Brazil

29 March 2022

Article: 56/1202

The Brazilian Ministry of Health reports continued transmission of Zika virus in all five regions of the country. Between 1 January and 11 March 2022, there were 756 reported cases of Zika virus disease, an increase of 11.5% compared to the same period in 2021, with the Northern Region being the part of the country most affected. 

Zika virus infection is caused by the Zika virus (ZIKV) and is spread by mosquito bites which in pregnancy may result in congenital Zika syndrome, which may cause severe consequences for the baby. 

Advice for travellers 

Aedes mosquitoes, which transmit ZIKV, are particularly persistent and aggressive, and bite between dawn and dusk. All travellers to countries that have reported ZIKV infection must consider:

  • strict mosquito bite avoidance measures, especially travellers who are pregnant or planning pregnancy
  • using condoms and contraception if sexually active, to avoid the sexual transmission of ZIKV and the risk of ZIKV in pregnancy, during travel and on return for two months if female or three months if male
  • travel insurance, in particular pregnant women, who should check with their travel insurance company that they are covered under the policy before booking their trip, and be aware that the risk of ZIKV in any country may change during the time between planning the trip and travelling
  • if there are any additional travel recommendations for pregnant travellers, those planning pregnancy and for preventing onward sexual transmission, which can be found under the Emerging Health Risks tab of individual TRAVAX country pages and the Alerts section of individual fitfortravel country pages 

Further information on ZIKV can be found on the TRAVAX (for health professionals) and fitfortravel (for the general public) websites.
