Global Dengue Epidemic Intensifies as Zika Resurgence Threatens Public Health

Brazil leads with the first-ever public health vaccination campaign against dengue amid rising concerns over Zika's impact on pregnancies.

Dengue cases and related deaths are escalating globally, with over half a million cases and over 100 deaths reported in January 2024 alone.
Brazil has initiated the world's first public health vaccination campaign against dengue, using the Qdenga vaccine, which shows over 61% effectiveness.
The resurgence of Zika virus, especially in Thailand, poses a significant risk, particularly during pregnancy, due to its potential to cause microcephaly and brain damage in unborn babies.
Climate change and rapid urbanization are identified as primary factors driving the unprecedented spread of dengue around the world.
Preventive measures against mosquito-borne diseases include using repellents, wearing long sleeves and pants, and sleeping in air-conditioned rooms.
