Hantavirus in Hinesville, GA — Rice Rats, Cotton Rats, Symptoms & Safe Cleanup

The Coastal Georgia Factor — Why Hinesville's Risk Looks Different

Most hantavirus cases in the U.S. come from the deer mouse and the Sin Nombre virus out West. The CDC reports that 94% of U.S. hantavirus cases have occurred west of the Mississippi River. Coastal Georgia's picture is different, and it's shaped by two native Southeast rodents:

• Marsh rice rat — a semi-aquatic rat that lives in marshes and wet, grassy edges. It carries Bayou virus. A 2025 CDC research letter reports Bayou virus–infected rodents have been identified in Texas, Louisiana, Georgia and South Carolina.
• Hispid cotton rat — lives in overgrown areas with shrubs and tall grass. It carries Black Creek Canal virus, which caused a confirmed human case in south Florida.

Around Hinesville, that habitat is everywhere: tidal marsh toward Midway, drainage ditches, wooded lots, and fields left to grow up. Human cases from these Southeast viruses are uncommon, but the rodents that carry them live close to where people store boats, clear brush and open up sheds.

Which Rodents Around Hinesville Matter — and Which Don't

Most homeowners can't tell these species apart from droppings alone, which is why the CDC treats any rodent droppings with the same careful cleanup method.

How Exposure Actually Happens in Liberty County

Hantavirus spreads mainly when dried rodent urine, droppings or nesting material get stirred into the air and breathed in. It can also spread through a bite, but that's rare. The risky moments are ordinary ones:

• Opening a shed, detached garage, storage unit or boat storage area that's been closed for months.
• Coming back to a house that sat empty during a deployment or PCS move and finding droppings in the kitchen or attic.
• Clearing brush, tall grass or an overgrown lot where cotton rats nest.
• Sweeping or vacuuming droppings in a closed space, which throws particles into the air.

Unsafe vs. CDC-Recommended Cleanup

Heavy droppings, nesting in insulation, or a closed attic or crawl space is a job for a licensed pro with proper protective equipment, not a weekend DIY project.

Symptoms to Watch For After Possible Exposure

According to the CDC, hantavirus pulmonary syndrome symptoms usually start 1 to 8 weeks after contact with an infected rodent.

• Early: fatigue, fever, and muscle aches, especially in the thighs, hips, back and sometimes shoulders.
• In about half of patients: headache, dizziness, chills, and stomach problems like nausea, vomiting, diarrhea or abdominal pain.
• 4 to 10 days later: coughing and shortness of breath as the lungs fill with fluid.

How Rodent Exclusion Removes the Ongoing Risk

Hantavirus risk inside a home grows with the amount of rodent activity. The CDC's own advice is to seal holes and gaps, trap rodents in and around the home, and remove easy food sources. In practice that means:

• Sealing entry points around pipes, vents, soffits and garage doors with durable materials like steel mesh and metal flashing, not foam alone.
• Trapping the rodents already inside.
• Safe attic and crawl space cleanup so old droppings and nests aren't left behind.
• Cutting back tall grass and brush near the house, where cotton rats shelter.
