*H. pylori* can persist in the stomach for decades, increasing gastric cancer risk through chronic inflammation. Discover why this bacterium contributes to thousands of cancer cases in Latin America and how treating it could help prevent cancer.
What happens to your blood sample after a dengue test? Learn how RT-PCR detects dengue virus, why it’s most accurate during the first week of illness, and why timing is critical for diagnosis.
Qualitative research helps explain why people accept, delay, or refuse vaccines. By combining findings from multiple studies, systematic reviews can guide more effective vaccination policies across Latin America.
Dengue fever is spreading into new regions in 2026, driven by expanding mosquito habitats and growing outbreaks worldwide. Learn the early dengue symptoms, recognize the warning signs of severe dengue, and discover which regions face the highest risk this year.
Hantavirus cases are rising across Latin America due to environmental change, rodent exposure, and climate shifts. Learn the symptoms, risks, and prevention strategies.
A rare Andes hantavirus outbreak aboard a cruise ship has drawn global attention after multiple deaths and confirmed human-to-human transmission. Here is what the outbreak means for public health, travel, and Latin America.
Is your drinking water safe? Antibiotic-resistant H. pylori may spread through tap water via wastewater contamination and biofilms, posing an overlooked health risk.
Quantifying viral infection begins at the molecular level. In laboratories around the world, scientists use quantitative PCR (qPCR) to detect tiny amounts of viral genetic material and estimate viral load. This powerful technology allows researchers and clinicians to measure infection in real time and guide both diagnostics and outbreak response.
Natural insect repellents are increasingly popular across Latin America, but most offer little real protection. A 2023 study tested plant-based ingredients against mosquitoes and ticks and found that only a few—cinnamon oil, clove oil, and geraniol—provided meaningful, multi-vector repellency. This blog breaks down which natural repellents actually work and what that means for real-world disease prevention.
Natural repellents are widely used across Latin America, but most fail to prevent mosquito bites. New evidence shows only a small number of plant-based ingredients provide real, short-term protection—highlighting the risks of relying on ineffective products.
An 18-year pediatric cohort study from Nicaragua shows that dengue, chikungunya, and Zika symptoms change with age and over the first 10 days of illness. Fever patterns, rashes, and blood markers evolve differently across childhood, revealing diagnostic clues that static symptom checklists often miss. Tracking symptom trajectories over time leads to more accurate differentiation of these infections.
Dengue is not a single disease with a single outcome. While most infections cause a self-limited fever, severe dengue follows a different and far more dangerous path. This article explains the critical differences between dengue fever and dengue hemorrhagic fever, why the highest risk often appears when fever breaks, and how recognizing plasma leakage can save lives.
