Hantavirus infections are uncommon, but doctors take them seriously because symptoms can worsen very quickly.
Early signs often resemble seasonal flu. A person may develop fever, fatigue, muscle pain, headaches, nausea, vomiting, or dizziness. Because these symptoms are vague, many people ignore them at first.
But the disease can suddenly become severe.
“Though rare, hantavirus infection can be severe. According to the CDC, hantavirus pulmonary syndrome (HPS) has a mortality rate of nearly 38% once respiratory symptoms develop. Early symptoms resemble flu — fever, fatigue, body aches, nausea, and headaches — before progressing rapidly to breathing difficulty and lung involvement,” says Dr Rajamanya.
The lungs can fill with fluid within days, making breathing extremely difficult. Patients often require emergency hospital care.
The National Institutes of Health (NIH) hantavirus overview explains that early diagnosis can improve outcomes, especially when supportive respiratory care begins quickly.
Gardens, sheds, and storerooms need more attention than people think
Rodents are drawn to quiet spaces with easy nesting material and accessible food. Garden sheds, stacked newspapers, pet food corners, compost areas, and unused storage boxes create ideal environments.
Experts say the risk increases after long monsoons, flooding, rural farming activity, or colder months when rodents move closer to homes.
A forgotten gardening glove or old blanket stored in a shed may not look dangerous. Yet if rodents have nested nearby, the surrounding dust could become contaminated over time.
