Dengue is surging across the Americas early this year from Puerto Rico to Brazil.
A brigade fumigates to combat dengue amid a surge in cases nationwide in Buenos Aires, Argentina, Tuesday, March 26, 2024. – Dengue is surging across the Americas early this year from Puerto Rico to Brazil, with 3.5 million cases of the tropical disease reported so far, health officials said Thursday.
The dengue virus is spread to people when they are bitten by infected mosquitoes. Driving the surge are rising temperatures, rapid urbanization, droughts and floods linked to climate change, and poor sanitation and a lack of robust health systems in some countries, health officials said. Most of the current cases are in the Southern Hemisphere, with more than 80% in Brazil, followed by Paraguay, Argentina, Peru and Colombia. Some 1,000 deaths have been reported in the Americas so far this year.
There are four different dengue viruses circulating in the Americas, said the PAHO's Dr. Sylvain Aldighieri. “We have to be prepared for this.”
