Hantavirus in Mississippi: what the 2026 news means
Hantavirus was in the headlines in May 2026 after cases tied to a cruise ship. Mississippi health officials called the risk here low. Here is what actually happened, who carries the virus, and when it is worth being careful around Oxford.
- No Mississippi case since 1993
- Risk called low
- Deer mice, not house mice
- Air out closed buildings
Opening up a camp or shed? See where the real risk is.

Is hantavirus a risk in Mississippi right now?
The risk is low. The Mississippi State Department of Health says no hantavirus case has been reported in Mississippi since the disease became nationally reportable in 1993. The May 2026 news was about the Andes strain on the M.V. Hondius cruise ship, and state epidemiologist Dr. Renia Dotson told MPB that with no Mississippi passengers identified, the state was at very low risk. In the US, the main carrier is the deer mouse, according to the CDC. The situations worth care around Oxford are closed-up camps, cabins, sheds and barns with mouse droppings. The CDC says to air those out for 30 minutes before cleaning, and never sweep or vacuum droppings dry. If you get fever and muscle aches 1 to 8 weeks after rodent exposure, see a doctor and mention the rodents.

In May 2026, hantavirus cases linked to the M.V. Hondius cruise ship led to evacuations and monitoring of passengers. MPB News reported on May 15 that 41 Americans were being monitored, American passengers were quarantined in Omaha, Nebraska, and none had apparent Mississippi links.
The cruise cases involved the Andes strain, which is unusual because it can spread from person to person. Most hantaviruses spread only from rodents. The CDC says Andes spread is usually limited to people in close contact with someone who is sick, and WJTV reported on May 12 that experts stressed it does not spread easily.
Dr. Dotson told WJTV that people who were not aboard the ship and had no contact with a diagnosed person have essentially no concern. Officials also pointed to the virus’s 42-day incubation period: if no new cases appeared in that window, there was no ongoing threat.
Who carries it
Who carries hantavirus in the US
Host species from the CDC’s MMWR hantavirus recommendations; main carrier from the CDC hantavirus page.
| Rodent | Hantavirus link in the US |
|---|---|
| Deer mouse | Main US carrier (Sin Nombre virus). The CDC calls it common and widespread in rural areas. |
| White-footed mouse | Host of New York virus |
| Cotton rat | Host of Black Creek Canal virus |
| Rice rat | Host of Bayou virus |
| House mouse | Not one of the hosts the CDC names for hantavirus pulmonary syndrome |
| Norway rat | Carries Seoul virus, a different illness; the CDC notes only three suspected US cases |
The rodent in most Oxford kitchens is the house mouse, which is not one of the US hosts in CDC reports. That does not make its droppings harmless; the CDC still says to clean up after any rodents safely. If you are not sure what you caught, our rodent identification guide shows how to tell the species apart.
The CDC also notes that nearly all of the continental US falls within the range of one or more of these host species. Low risk is not zero risk, so the same careful cleanup applies everywhere.
Real risk around Oxford
Where the real risk is around Oxford
The common thread: closed spaces, stirred-up dust and lots of droppings.
Closed-up hunting camps
A camp shut since last season, opened in fall with droppings on the counters and in the bunks. This is the textbook case.
Cabins and lake houses
The CDC lists occupying or cleaning vacant cabins that are infested with rodents as a risk factor.
Sheds and storage rooms
Closed sheds full of nests in boxes and old feed. The CDC says to ventilate before cleaning them.
Barns and feed rooms
Nests in hay and feed, in buildings that stay closed much of the time.
Stored vehicles and equipment
Campers, tractors and cars that sat for months with nests in the cab or engine bay.
Heavy infestations anywhere
Lots of fresh droppings and nesting material in a tight, closed space is what raises the risk.

Symptoms
Symptoms, timing and when to see a doctor
Symptom timing from the CDC; Andes incubation from MSDH.
| Stage | What the CDC describes |
|---|---|
| Timing | Symptoms usually start 1 to 8 weeks after contact with an infected rodent |
| Early | Fatigue, fever and muscle aches, especially in the thighs, hips and back |
| Also common early | About half of patients have headaches, dizziness, chills or stomach problems |
| Later | 4 to 10 days after the early phase: coughing, shortness of breath and chest tightness |
| Andes strain | MSDH lists an incubation of about 4 to 42 days |
If you get sick after cleaning a camp, shed or other rodent-heavy space, see a doctor right away and tell them about the rodent exposure, as the CDC advises. Early symptoms look like the flu, so that detail matters.
It is rare, but it is serious when it happens: the CDC says 38% of people who develop the lung symptoms may die. That is why prompt care matters. This is general information, not medical advice.
Rodents at the camp or house
Droppings in a closed-up camp, shed or attic?
Call or send the form. We find how the mice are getting in, seal with metal, trap what is inside and confirm with a full quiet week. The price is in writing before any work starts.
Cleanup in brief
Cleanup in brief
Steps from the CDC’s Clean Up After Rodents page.
The rule from both MSDH and the CDC is simple: wet it, do not stir it up. Sweeping and vacuuming dry droppings can put virus particles into the air.
This is the short version. Our droppings cleanup guide has the full step-by-step, including attics, crawl spaces and cars.
- Open doors and windows for 30 minutes and leave
- Wear rubber or plastic gloves
- Mix 1 part bleach to 9 parts water, fresh
- Spray droppings and nests and let soak 5 minutes
- Wipe up with paper towels and bag the trash
- Never sweep or vacuum droppings dry
- Wash your hands when you are done

Straight answers
Hantavirus questions
How many hantavirus cases has Mississippi had?
None reported. MSDH reports no hantavirus cases in Mississippi since it became nationally reportable in 1993, and state health officials called the risk low after the 2026 cruise ship cases. Careful cleanup of droppings in closed buildings is still smart.
Did the 2026 hantavirus cases reach Mississippi?
No Mississippi links were found. MPB reported that none of the 41 Americans monitored after the M.V. Hondius cruise had apparent Mississippi ties, and WJTV reported no confirmed cases or exposures in the state.
Can house mice give you hantavirus?
The main US carrier is the deer mouse. The CDC’s list of US hantavirus hosts does not include the house mouse. Clean up any rodent droppings with care anyway.
Can hantavirus spread from person to person?
Only the Andes strain is known to, and the CDC says that is usually limited to close contact with someone who is sick. The hantaviruses found in the US spread from rodents.
How do people get hantavirus?
Mostly by breathing in particles from rodent urine, droppings or nesting material that get stirred up, or touching contaminated surfaces and then the face, according to MSDH. Bites are rare.
How should I open up a camp or shed that sat closed all summer?
Do not sweep it dry. Air the building out for 30 minutes, wear gloves, soak droppings with bleach solution for 5 minutes, then wipe them up.
When should I see a doctor?
If you get fever, fatigue and muscle aches within about 1 to 8 weeks after rodent exposure, see a doctor right away and mention the rodents.
