A new virus has emerged in Georgia and it’s causing concern. Hantavirus refers to a family of viruses primarily transmitted by rodents, capable of causing serious, sometimes fatal illnesses in humans. In the Americas, it often leads to hantavirus pulmonary syndrome (HPS), a severe respiratory condition.
While rare in the southeastern U.S., recent events have drawn attention to hantavirus in Georgia (the U.S. state).
Recent Developments: Monitoring in Georgia
As of early May 2026, the Georgia Department of Public Health (DPH) is monitoring two Georgia residents who returned from the MV Hondius cruise ship, linked to a hantavirus outbreak. The ship, on an Atlantic Odyssey voyage, reported at least three deaths and several confirmed or suspected cases, involving the Andes virus strain (the only known hantavirus with documented person-to-person transmission, though usually limited to close contacts).
- The two Georgians (one reported in the Brunswick area) are healthy and show no symptoms.
- They are under monitoring per CDC guidelines, with no immediate public risk.
- Health officials in other states (e.g., California, Arizona, Virginia) are similarly watching returned passengers.
This outbreak likely originated from rodent exposure during a pre-boarding excursion in Argentina (possibly Ushuaia), not widespread community spread.
Background on Hantavirus in Georgia and the U.S.
Hantavirus is not endemic in Georgia. Most U.S. cases occur west of the Mississippi River, often tied to deer mice. From 1993 through 2023, the CDC reported about 890 laboratory-confirmed U.S. cases of hantavirus disease (including HPS), with a case fatality rate around 35-38% for HPS. Georgia has seen very few, if any, locally acquired cases historically.
A separate 2009 report noted a lab-confirmed case in the Republic of Georgia (the country), but that is unrelated to the current U.S. context.
How It Spreads
Humans typically contract hantavirus by inhaling aerosolized particles from infected rodent urine, droppings, or saliva. Less common routes include direct contact with contaminated materials (then touching the face) or rodent bites. It does not spread easily between people, except in rare cases with the Andes strain.
Rodents like deer mice carry it without getting sick, shedding the virus in their waste. Cleaning infested areas without precautions (e.g., dry sweeping) can aerosolize particles.
Symptoms
HPS symptoms appear 1–8 weeks after exposure and progress in phases:
- Early phase (flu-like): Fatigue, fever, muscle aches (especially large muscles like thighs, hips, back), headaches, dizziness, chills, nausea, vomiting, diarrhea, abdominal pain.
- Later phase (4–10 days after early symptoms): Coughing, shortness of breath, chest tightness as lungs fill with fluid, leading to respiratory distress and potential shock.
Seek immediate medical care if you have flu-like symptoms after possible rodent exposure—early intervention improves outcomes.Treatment and PrognosisNo specific antiviral cure exists for HPS. Treatment is supportive, often in an ICU, and may include oxygen therapy, mechanical ventilation, fluid management, or ECMO (extracorporeal membrane oxygenation) in severe cases. Recovery can be slow, with lingering fatigue. Prompt care significantly boosts survival chances.
Prevention Tips
Prevention focuses on rodent control—key in homes, cabins, or campsites:
- Seal entry points in buildings.
- Store food in rodent-proof containers and maintain cleanliness.
- Use traps; avoid live rodents.
- When cleaning droppings: Ventilate the area, wear gloves and an N95 mask, wet-clean with disinfectant (e.g., bleach solution), and avoid vacuuming or sweeping dry material.
- For campers or hikers: Use tents with floors, elevate food, and check for rodent signs.
Outlook for Georgia
The risk remains very low for most Georgians. The current monitoring reflects standard public health vigilance rather than local transmission. Stay informed via the Georgia DPH or CDC websites, especially if traveling to rodent-prone areas or on international trips.
Hantavirus serves as a reminder of the importance of rodent control and awareness of zoonotic diseases. If you suspect exposure or symptoms, contact a healthcare provider and mention any rodent contact. For questions, reach Georgia DPH Epidemiology at (404) 657-2588 or the 24/7 line at 1-866-PUB-HLTH.
