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 Symptoms in 2026: What to Watch For
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.
Why Hantavirus Cases Are Rising Across Latin America
Hantavirus cases are rising across Latin America due to environmental change, rodent exposure, and climate shifts. Learn the symptoms, risks, and prevention strategies.
Andes Hantavirus Explained: What The Cruise Ship Outbreak Means
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.
Can H. pylori Enter Your Tap Water? How It Spreads
Is your drinking water safe? Antibiotic-resistant H. pylori may spread through tap water via wastewater contamination and biofilms, posing an overlooked health risk.
Inside The Lab: How Scientists Measure Viral Load Using qPCR
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.
Which Natural Repellents Protect Against Mosquitoes and Ticks?
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.
Do Natural Insect Repellents Work? What The Science Says
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.
How Dengue, Chikungunya, and Zika Symptoms Change With Age
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 Fever vs Dengue Hemorrhagic Fever: Critical Differences
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.
Is H. pylori Contagious? What You Need to Know
Affecting millions worldwide and hitting Hispanic and Latino communities hardest, this silent infection spreads easily in close living conditions. Knowing how H. pylori spreads is crucial to preventing infection and protecting your family.
