Brazil's Carnival 2026 Preparations Include Zika Virus Avoidance

The Federative Republic of Brazil's iconic Carnival of 2026 will begin on February 13, drawing millions of locals and international visitors to cities like Rio de Janeiro, São Paulo, Salvador, and Recife.

As of January 22, 2026, Brazil is gearing up for this celebration, focusing on fun while prioritizing public health.

Local health authorities are urging caution due to concerns about mosquito-borne diseases, particularly the Zika virus, with over 24,000 suspected and 1,840 confirmed cases reported by Brazil's Ministry of Health by the end of December 2025.

Last year, many Zika cases were concentrated in the higher population states like São Paulo and Rio de Janeiro.

While Carnival's crowds and warm weather heighten exposure risks, simple precautions can help ensure a safe experience. 

Currently, there are no vaccines for Zika available, and disease prevention relies on measures such as using insect repellent, wearing long clothing, and eliminating standing water.

Travelers, especially pregnant individuals, should consult healthcare providers and follow guidance from health authorities, such as the U.S. Centers for Disease Control and Prevention (CDC).

While the CDC has not issued a Travel Health Notice regarding Zika outbreaks in Brazil, it did confirm that an infected pregnant woman can spread it to her unborn baby, which may cause microcephaly. 

In addition to Zika, the CDC has highlighted travel vaccinations for chikungunya and yellow fever when planning to visit Brazil in 2026.
