What's Happening Today — May 13, 2026
The hantavirus story that began on a remote expedition cruise is now on American soil. As of this morning, 18 Americans from the MV Hondius — the cruise ship at the center of a confirmed Andes virus outbreak — have been repatriated to the United States. Sixteen are being monitored at the National Quarantine Unit at the University of Nebraska Medical Center. Two others have been transferred to a biocontainment unit, one of whom tested positive for the Andes strain of hantavirus.
Meanwhile, the Illinois Department of Public Health is investigating a separate, unrelated potential hantavirus case in Winnebago County — a reminder that the rodent-borne Sin Nombre strain, the type of hantavirus most common in the U.S., doesn’t need a cruise ship to spread. Kansas health officials have also confirmed three hantavirus exposures in that state, unrelated to the cruise ship outbreak.
Here is what you need to understand — calmly, clearly, and without panic.
The Two Hantaviruses in the News
Andes virus (cruise ship outbreak): Found primarily in South America, specifically Argentina and Chile. It is the only known hantavirus strain capable of limited human-to-human transmission — and even that requires close, prolonged contact such as sharing a bed or exchanging bodily fluids. The CDC and WHO both rate the risk to the American general public as extremely low. As of May 12, 2026, 11 people from the MV Hondius have been confirmed infected, and three have died.
Sin Nombre virus (domestic, rodent-borne): This is the strain responsible for the Illinois and Kansas cases, and for the roughly 800 U.S. hantavirus cases recorded since tracking began in 1993. It does not spread human to human. It spreads when a person breathes in dust contaminated with the urine, droppings, or saliva of infected deer mice — most often during cleaning of enclosed spaces like cabins, sheds, garages, or attics where rodents have nested.
What the CDC Is Recommending Right Now
The following guidance is sourced directly from the CDC’s Hantavirus Prevention & Control guidelines:
- Do not sweep or vacuum rodent droppings. Stirring them into the air is how the virus reaches your lungs.
- Wet down contaminated areas with a disinfectant solution before wiping. The CDC recommends a 10% bleach solution — or an EPA-registered disinfectant — applied for a minimum of 5 minutes of contact time.
- Wear rubber or plastic gloves during cleanup. Dispose of gloves and wash hands thoroughly afterward.
- Seal rodent entry points in your home. Steel wool, hardware cloth, and caulk are your best materials.
- Store food — including pet food — in sealed, rodent-proof containers.
Does Your Disinfectant Actually Kill Hantavirus?
This is the question most people don’t ask until they’re already cleaning up a mess. The answer matters. Many common household products — including hand sanitizer, Pine-Sol, and general multipurpose sprays — do not kill hantavirus on surfaces. For the full breakdown of what works and what doesn’t, see our detailed guide: Does Hand Sanitizer Kill Hantavirus? The Honest Answer — and What Actually Works.
Hantavirus is an enveloped RNA virus — meaning it has a lipid envelope that is actually easier to disrupt than the hard protein shells of non-enveloped viruses like norovirus. Properly formulated EPA-registered disinfectants destroy enveloped viruses effectively when used correctly.
SONO Disinfecting Wipes carry EPA Registration #6836-340-89018 and are hospital-grade, alcohol-free, and safe on virtually any surface. Unlike paper towels and spray bottle setups that are hard to control in enclosed, dusty spaces, wipes let you apply the right amount of solution to a surface and hold it in contact for the dwell time required — without aerosolizing anything.
Recommended for rodent cleanup and routine disinfection:
🧻 SONO Disinfecting Wipes — 80 Count Canister — the workhorse for counters, desks, equipment surfaces, and anywhere you want hospital-grade disinfection at home or in the office. From $16.99.
🧻 SONO Disinfecting Wipes — 80 Count Soft Pack — flexible, portable, ideal for gym bags, car glove boxes, travel kits, and anywhere the canister won’t fit. From $18.99.
The Bigger Picture: Why Hantavirus Appears in the News Every Spring
Hantavirus is not new, and the current headlines — alarming as they feel — are not evidence of a new pandemic threat. The Sin Nombre strain, which causes Hantavirus Pulmonary Syndrome (HPS) in the U.S., has averaged fewer than 40 cases per year for three decades. For a comprehensive overview of the virus, its history, transmission, symptoms, and every disinfectant that actually kills it, read our full guide: Hantavirus: The Facts, Not the Fear.
What to Watch This Week
- Follow-up testing results for the American passenger who tested “mildly PCR positive” for Andes virus
- IDPH findings on the Winnebago County case — specifically whether it is linked to deer mice exposure in a rural setting
- CDC contact tracing for the 9 Americans who returned directly to their home states from the repatriation flight
- WHO assessment of whether the Andes strain’s transmission profile has changed
