Zika, dengue transmission expected to rise with climate change


The number of deaths in Brazil due to dengue hit a record high in 2022, with 1,016 — the first time in history the number had surpassed four digits. And the sobering statistic is expected to be even higher in 2023.

According to the Center for Arbovirus Emergency Operations, 635 fatal cases had been reported by June 11 — up 22% as compared with the same period in 2022. The agency's most recent update, released by the Ministry of Health, shows 1.3 million probable cases so far this year, while the total number for 2022 was 1,450,270 cases.
