Pregnant women may have higher severity from Andes virus. Children get HPS less often but more severely. Limited data, fetal outcomes, and pediatric symptom patterns.
Climate Change and Hantavirus: Why Wet Years Mean More Cases
El Niño 1993 triggered the Four Corners outbreak via mouse population booms. How climate variability drives hantavirus risk, and why the wet-year-then-dry pattern matters.
Is There a Hantavirus Vaccine? China and South Korea Have One — Why the West Doesn't
China and South Korea use HFRS vaccines for endemic areas. The US has no approved vaccine. Current trials, mRNA candidates, and why approval lags.

Grain farmers, construction, pest control, field biologists, utility workers — the documented occupational hantavirus cases. Risk levels, PPE, and what employers should provide.
How Hantavirus Surveillance Actually Works: WHO, CDC, ECDC, PAHO Roles Explained
Each agency tracks hantavirus differently. WHO IHR notifications, CDC HAN alerts, ECDC weekly bulletins, PAHO regional reports. What each catches and what each misses.
Can Dogs, Cats, or Pet Rats Carry Hantavirus? What Veterinarians Actually Test For
Dogs and cats do not get sick from hantavirus and are not reservoirs. Pet rats CAN carry Seoul virus. What testing exists and what to do if your pet hunts mice.
The 1993 Four Corners Hantavirus Outbreak: How a Mystery Disease Got a Name in 9 Weeks
The Sin Nombre virus discovery in Four Corners, May 1993. How CDC field investigators went from 'mystery flu' to identifying a brand-new hantavirus species in nine weeks.
Hantavirus and Seasonal Cabin Cleanup: The 30-Minute Rule and What to Do First
Reopening a cabin, attic, or shed after winter is the number one hantavirus exposure scenario. The 30-minute ventilation rule, what to spray, what to never do.
Which Mice Carry Hantavirus? The 6 Reservoir Species to Identify
Not every mouse carries hantavirus. Deer mouse and cotton rat are the main US reservoirs; long-tailed pygmy rice rat carries Andes virus. How to identify them and what to do.
HPS vs HFRS: The Two Hantavirus Syndromes and Why Geography Decides Yours
Hantavirus causes two distinct syndromes: pulmonary in the Americas, hemorrhagic-renal in Eurasia. The mechanisms, mortality, and reservoir species differ completely.
Hantavirus Risk When Traveling to South America: Country and Activity Guide
Argentina, Chile, Uruguay carry the highest hantavirus risk for travelers. Country-by-country breakdown, activity risk levels, and what travel insurance actually covers.
Hantavirus Treatment: No Cure, But ECMO Cuts Mortality From 50% to 20%
There is no antiviral cure for hantavirus. What ICU teams actually do: ECMO, fluid restriction, why ribavirin works for HFRS but not HPS, and emerging antibody therapies.
Hantavirus Incubation Period: Why 4 to 42 Days Means Different Things for Different Strains
Hantavirus incubation ranges from 4 days to 8 weeks depending on strain. How to count from exposure, what the variation means, and when you can stop worrying.
Hantavirus in Rural Homes: What the Arakawa Case Taught Us About Domestic Exposure
Betsy Arakawa's 2025 death brought rare attention to domestic hantavirus exposure. What the case revealed about diagnosis gaps, rural risk, and what every homeowner should know.
Hantavirus vs Flu vs COVID: How to Tell the Difference in the First 72 Hours
Hantavirus early symptoms are nearly identical to flu and COVID. The differentiators: rodent exposure history, muscle pain location, and the 4-10 day deterioration pattern.
How to Safely Clean Mouse Droppings to Avoid Hantavirus (CDC Protocol)
Step-by-step CDC cleanup protocol for rodent droppings. Bleach ratio, ventilation timing, PPE requirements, and the three things people get wrong most.
Is Hantavirus Airborne? The Mechanism, Distance, and Survival Time Explained
Hantavirus is aerosolized but not airborne in the COVID sense. How particles travel, how long they survive on surfaces, and why ventilation matters more than masks.
