Short answer
Early symptoms can feel flu-like. Later symptoms can include coughing, shortness of breath, and severe breathing problems.
What it means
CDC describes early symptoms such as fatigue, fever, and muscle aches. Some people also have headache, dizziness, chills, nausea, vomiting, diarrhea, or abdominal pain. Later symptoms can include cough and shortness of breath.
What to know
Symptoms alone do not prove Hantavirus because many illnesses can look similar at first. Exposure history, timing, medical evaluation, and testing matter.
When to check official guidance
If symptoms appear after possible rodent exposure, contact a healthcare professional and mention the exposure. Seek urgent care for breathing trouble or rapidly worsening illness.
