What Is Hantavirus & Should You Be Worried About It?

Viruses, Rodents, and Your Well-Being in the Modern Era

People today understandably worry about highly infectious diseases—especially in the wake of COVID-19. Headlines often mention “rat diseases” such as hantavirus. You can protect yourself by learning what hantaviruses are and how to reduce your risk.

Grasping the Hantaviruses of the World

Hantaviruses are a family of viruses primarily carried by rodents—commonly rats and certain mice (e.g., deer mice, white-footed mice, cotton rats, rice rats). Human illness can occur after exposure to infected rodents or their droppings, urine, nesting materials, or contaminated dust.

The Perils of Hantaviruses

Infection can lead to Hantavirus Pulmonary Syndrome (HPS), a severe respiratory illness. Anyone exposed to infected rodents can be at risk, which is why swift, thorough rodent control at the first sign of activity is so important.

Indications That You May Have HPS

Early recognition matters—seek medical care promptly if you notice concerning symptoms. Early signs can include unusual fatigue, muscle aches, and fever, especially in the back, hips, thighs, and shoulders. Some people also experience persistent headaches, abdominal pain, chills, or lightheadedness.

HPS Symptoms

• Exhaustion
• Muscle pain
• Fever
• Back, hip, thigh, shoulder, or abdominal pain
• Headaches & lightheadedness
• Chills
• Shortness of breath
• Cough

As HPS progresses, shortness of breath and cough can worsen. The disease can be fatal in a substantial percentage of cases (often cited around 38%), underscoring the need for prevention and rapid medical evaluation.

Keeping HPS at Bay

Reduce risk by minimizing contact with rodents and their droppings:

• Seal gaps and openings (≥ 1/4 inch) around your home, garage, and outbuildings.
• Use effective traps in and around structures to prevent infestations.
• Eliminate food sources—store food in sealed containers and clean up spills promptly.
• Avoid direct contact with rodent carcasses, droppings, and nesting materials; follow safe cleanup practices.

Are Hantaviruses Contagious?

In North America, HPS is not known to spread from person to person. Transmission occurs from rodents to humans.

HPS and Treatment Approaches

There is no specific antiviral treatment for HPS. Outcomes improve with early recognition and supportive care, often including oxygen support and, in severe cases, mechanical ventilation. Prompt medical attention can improve survival. No vaccines are currently available for HPS.

Severe cases may lead to respiratory failure; recovery can take weeks. Early clinical care is critical.

Hantaviruses Around the Globe

Hantaviruses vary by region. In the Americas, infections are most associated with HPS. In parts of Europe and Asia, related hantaviruses more commonly cause HFRS (hemorrhagic fever with renal syndrome). Clinical syndromes and risks differ by geography and rodent reservoir.
