Climate change is accelerating dengue risk across Latin America, with new high-resolution models showing that global warming could add millions of infections in the coming decades. Research from Colón-González et al. reveals that limiting warming to 1.5 °C dramatically reduces future dengue cases, shortens transmission seasons, and offers major public health benefits for Brazil, Colombia, Mexico, and other vulnerable regions.
Brazil is facing a major dengue surge in 2024, driven by the reemergence of the DENV-3 serotype after 15 years. New surveillance data reveal nearly 2 million suspected cases in just three months, with women, children, and Indigenous people disproportionately affected. As climate pressures, social inequality, and low immunity collide, Brazil now accounts for much of Latin America’s rising dengue burden, highlighting urgent gaps in vaccination, mosquito control, and equitable healthcare access.
Aedes aegypti mosquitoes transmit dengue, Zika, and chikungunya, but chikungunya dominates infection rates in Mérida, Yucatán. This study highlights how mosquito density influences transmission and why accurate surveillance is critical for preventing outbreaks.
Artificial light at night (ALAN) is more than an environmental nuisance, it’s a growing public health risk. A new study reveals that brief exposure to nighttime light can double the biting rate of Aedes aegypti mosquitoes, heightening the risk of dengue, Zika, and chikungunya transmission across Latin America’s rapidly urbanizing regions. As cities grow brighter, so does the hidden danger buzzing in the dark.
Aedes aegypti and Aedes albopictus mosquitoes are key vectors behind dengue, Zika, and chikungunya. Discover how their feeding habits, infection rates, and adaptability fuel global arbovirus outbreaks.
Uncover how dengue virus triggers fever, pain, and rash. Learn key dengue fever symptoms and safe over-the-counter treatments.
Women in Latin America may face a higher risk of severe dengue due to biological, social, and behavioral factors. From pregnancy complications to increased mosquito exposure at home, the dangers are real. This post explores why women need extra protection, and the top three steps they can take to stay safe during dengue outbreaks.
As Latin American women continue to lead in politics, science, and entrepreneurship, they face a quieter but growing threat: dengue. In 2024 alone, the region saw over 13 million dengue cases, with new research revealing that women, especially those of reproductive age, are more likely to suffer severe complications. From biological factors like estrogen’s impact on immunity to social roles that increase mosquito exposure, the gender gap in arboviral infections is real and urgent. With evidence mounting from countries like Brazil, experts are calling for gender-sensitive public health strategies, including targeted vector control, reproductive care, and expanded vaccine access to protect those most at risk.
Oropouche virus (OROV) and dengue virus (DENV) share overlapping symptoms like fever and headache, but key differences, such as sore throat and abdominal pain, can help with early diagnosis and effective treatment. This article breaks down the latest clinical findings, explores the biological mechanisms behind these symptoms, and recommends safe over-the-counter (OTC) remedies to manage discomfort without the risks of NSAIDs.
New 2025 research reveals key differences between Oropouche fever and dengue virus infections. Learn how to spot predominant symptoms like sore throat and abdominal pain that can help distinguish OROV from DENV during outbreaks in Latin America.
As climate change reshapes ecosystems across Latin America, a silent viral threat is emerging: the Oropouche virus (OROV). Once confined to forested regions, OROV is now infecting thousands in urban centers—spread by tiny midges thriving in warmer, wetter environments. With no vaccine or treatment, and symptoms that mimic dengue, the virus is spreading under the radar. This article explores how deforestation, rising temperatures, and rapid urbanization are fueling OROV’s rise, and what must be done to stop it.
