In the Americas, the number of dengue cases has been increasing rapidly. 

In the first five weeks of 2024, 11 countries have reported a rise in the number of infections.

The Pan American Health Organization (PAHO) has issued an epidemiologic alert, stating that compared to the same period in 2023, cases have increased by 157% and are 225% above the five-year average.

Last year, the Americas recorded over 4.5 million cases, and this year they have already recorded more than 6,73,000 dengue infections, including 700 severe cases and 102 deaths.

Brazil has reported the highest number of dengue infections with over 4,55,000 cases. 

All four serotypes of the virus are circulating in the Americas region this year, with varying proportions in different countries. 

However, Brazil, Costa Rica, Honduras, and Mexico are experiencing a circulation of all four serotypes.

In January, Brazil launched a dengue vaccination campaign, targeting 3.2 million people with the Qdenga vaccine manufactured by Takeda. 

This made Brazil the first country to offer a dengue vaccine through its public health system.

PAHO, in its latest alert, urged countries to intensify efforts to control Aedes aegypti mosquitoes, enhance surveillance, and ensure prompt diagnosis and treatment.
