Dengue remains a major public health threat across Latin America in 2026. Explore the latest PAHO outbreak data, affected countries, circulating dengue serotypes, and why health officials continue to emphasize surveillance, mosquito control, and early detection to prevent future epidemics.
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.
Why Measles Cases Are Rising Across Latin America in 2026
Measles cases are rising across Latin America in 2026 as vaccination rates decline. Learn how misinformation, migration, and health system challenges are fueling outbreaks.
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.
CRISPR vs PCR for Virus Detection: Why It Matters for Public Health
CRISPR diagnostics aren’t replacing Polymerase Chain Reaction yet—but they’re redefining what rapid virus detection can look like. As CRISPR tools advance and gain approval, they are poised to bring faster, more accessible testing closer to the communities that need it most.
Dengue Vaccines in Latin America: What’s Approved and Where They’re Being Used
Latin America faces rising dengue cases driven by climate and vector spread. This article explores available vaccines and their uneven distribution across the region.
Inside H. pylori Survival: How This Bacterium Thrives in Harsh Conditions
Helicobacter pylori can survive beyond the human stomach by entering a dormant state and forming protective biofilms in water systems. This hidden persistence raises new concerns for drinking water safety and disease transmission in Latin America.
Inside the Lab: How ELISA Detects Infection in Blood
ELISA is a widely used diagnostic tool that detects antibodies or antigens in blood, helping identify infections and track disease spread. By enabling large-scale testing, it plays a critical role in public health surveillance and outbreak response, especially in regions like 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.
Hidden Risk: Antibiotic-Resistant H. pylori in Peru’s Drinking Water
Antibiotic-resistant H. pylori has been detected in Peru’s drinking water, raising concerns that water systems may act as hidden reservoirs for infection and antimicrobial resistance.

Is H. pylori in Drinking Water? Insights from a Study in Peru
Could Helicobacter pylori be hiding in tap water? A recent study from central Peru detected the bacterium in household tap water and faucet biofilms, particularly where chlorine levels were low. The findings suggest drinking-water systems themselves may serve as environmental reservoirs for this cancer-linked pathogen.
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.
Why Social Inequality Shapes Arbovirus Risk in Brazil
Brazil’s Zika and chikungunya outbreaks are shaped by more than climate. Spatial analysis shows urban density, poor sanitation, and inequality significantly increase cluster risk. Even after adjusting for geography, socioeconomic conditions remain core drivers, linking arbovirus transmission directly to infrastructure and development gaps.
Predicting the Next Surge: Using Zika–Chikungunya Clusters to Guide Intervention
Zika and chikungunya outbreaks in Brazil move together, not separately. Space-time analysis reveals overlapping clusters driven by shared Aedes aegypti dynamics, summer heat, and regional climate conditions. When ecological risk rises, multiple arboviruses surge simultaneously — reinforcing the need for surveillance systems that anticipate co-circulating threats, not isolated outbreaks.
How Scientists Measure Gene Expression: From RNA to Cell Behavior
In the lab, scientists don’t ask cells questions — they measure gene expression. By tracking RNA, the messages genes send when they’re active, researchers can see whether cells are fighting infection, responding to treatment, or changing behavior. Techniques like qPCR, RNA sequencing, and single-cell analysis help decode these molecular signals.
Inside the Lab: How Scientists Detect Outbreak Clusters
Scientists don’t just count cases to detect outbreaks — they use spatial tools to find hidden patterns in disease spread. This article explains how scan statistics work and why univariate and multivariate approaches help reveal outbreak clusters and shared transmission environments across regions.
PCR vs Antigen Tests —What’s More Accurate?
PCR and antigen tests both detect viruses, but they work in very different ways. PCR amplifies viral genetic material for highly sensitive detection, while antigen tests identify viral proteins for faster results. Understanding when to use each test helps guide diagnosis, screening, and public-health decisions.
