Dengue, chikungunya, and Zika often circulate together, but in children they do not behave the same. Drawing on 18 years of pediatric data from Nicaragua, this analysis shows how symptom patterns and simple blood tests, rather than fever alone, can reliably distinguish these infections in real clinical settings.
Oropouche virus (OROV) is an emerging vector-borne disease rapidly expanding beyond the Amazon Basin and into new regions of Latin America and the Caribbean. Using advanced environmental and machine-learning models, researchers show that deforestation, land-use change, and climate conditions are creating widespread environments suitable for OROV transmission.
Which mosquito traps work best? A study in the Peruvian Amazon found that UV light traps outperformed others, capturing more mosquitoes and greater species diversity. The results show that different traps attract different species and that forest areas harbor far more mosquitoes than human-occupied sites, highlighting the importance of trap choice for effective dengue surveillance.
