Cases in Brazil
Leader in the number of registered cases, Brazil surpassed around 3.1 million probable cases of the disease this year. In 2024, the country has already recorded 1,292 confirmed deaths from the disease. Another 1,875 deaths are under investigation.
Countries With More Registered Cases
Although dengue is on the rise throughout Latin America and the Caribbean, the most affected countries are Brazil (83%), Paraguay (5.3%) and Argentina (3.7%), which account for 92% of cases and 87% of deaths.
Incidence Rate
When considering the incidence rate of the disease, the worst situation is in the French Guiana (3,768.63). Paraguay comes next with a rate of 2,818.89. Brazil has the third highest index – 1,816.28.
12 Countries with Outbreaks
The virus pandemic, however, does not only affect Brazil. Of the 25 countries covered by PAHO, 12 have outbreaks, with records of probable cases higher than projected.
El Niño as a Cause
The organization points out that the El Niño phenomenon is one of the causes that can be pointed out to justify the epidemic in Brazil and outbreaks in other countries. The phenomenon causes abnormal warming of the waters of the Pacific Ocean. Furthermore, rapid population growth and unplanned urbanization also play a crucial role: precarious housing conditions and inadequate water and sanitation services provide breeding grounds for mosquitoes in discarded objects and others used to accumulate water.
