Zika virus disease in Brazil

The Brazilian Ministry of Health (in Portuguese) reports continued transmission of Zika virus in all five Regions of the country.

Between 1 January 2022 and 11 March 2022 there were 756 cases of Zika virus disease, which is an increase of 11.5% increase in cases compared to the same period in 2021. The Northern Region is the part of the country most affected.

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

Advice for Travellers

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

• strict mosquito bite avoidance measures, especially pregnant travellers and those 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 2 months (if female) or 3 months (if male)
• travel insurance: pregnant women 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: these will be listed under the 'Emerging Health Risks' tab of TRAVAX country pages
