Study Reveals Arboviruses Increase Severe Risks for Newborns in Brazil

A large-scale study conducted by Fiocruz, Brazil’s leading public health research institution, recognized globally for its scientific excellence, has revealed that arbovirus infections during pregnancy are linked to significant risks for childbirth and newborn health. The analysis of more than 6.9 million live births between 2015 and 2020 showed that diseases transmitted by Aedes aegypti, such as dengue, Zika, and chikungunya, increase the likelihood of preterm birth, low birth weight, low Apgar scores (a measure of how well the newborn adapts after birth), and even neonatal death.

The findings confirm that the threat extends far beyond Zika, historically associated with congenital abnormalities. Dengue also showed links to fetal development issues, while chikungunya demonstrated a notable impact on neonatal mortality risk. The study further pointed out that the timing of infection during pregnancy plays a decisive role, with certain trimesters posing greater vulnerability.

These insights expand our understanding of how arboviruses affect maternal and infant health and highlight the importance of continuous monitoring throughout pregnancy. In socially vulnerable regions, where mosquito exposure tends to be higher, the consequences can be even more severe.

Reducing mosquito populations, strengthening vector-control strategies, and expanding access to reliable health information are essential steps to protect pregnant women and newborns. The study makes it clear: confronting arboviruses is not only a public health obligation but a vital action to ensure safer beginnings for future generations.

Sustainable mosquito-control tools, such as Aedes Mosquito Killers, offer an effective and accessible solution, especially in underserved communities where prevention is most urgently needed.
