Zika virus cases in Brazil 2015-2023

In 2023, Brazil reported around 35,000 cases of Zika virus disease, up from around 34,180 infections registered a year earlier. During the period analyzed, 2016 was the year with the most Zika infections in the South American country, with nearly 274,000 cases. In 2024, the value of the Zika virus vaccine market in Latin America is expected to reach approximately 2.7 billion U.S. dollars.

Brazil is the most affected country in Latin America

The Zika virus disease is mosquito borne and transmitted mainly through the bites of the Aedes aegypti, a mosquito also associated with dengue. Symptoms are often mild and include fever, headache, rashes, and joint pain. However, a Zika infection during pregnancy can cause certain congenital disorders. Between 2021 and 2023, Zika infections nearly doubled in Latin America, with Brazil reporting the highest number of Zika cases, followed by Bolivia and Belize in 2023. As of 2022, the most affected Brazilian region was the Northeast, where the majority of probable Zika cases were recorded.

Zika testing market value worldwide

As there is still no specific cure, vaccine, or treatment for Zika infections, preventing mosquito bites and safe sexual practices protect against this infection. Moreover, testing for Zika is recommended when symptoms appear after traveling to countries where the disease is still prevalent. Globally, the value of the Zika virus testing market has been increasing since 2020 and is expected to reach over 238 million U.S. dollars by 2026.
