Short answer
Andes virus illness can begin with flu-like symptoms and may progress to severe breathing problems in serious cases.
What it means
CDC describes Hantavirus pulmonary syndrome as starting with symptoms such as fever, fatigue, and muscle aches, with later cough and shortness of breath possible. Andes virus can cause severe Hantavirus disease, so exposure history matters.
What to know
Symptoms alone do not confirm Andes virus. Medical evaluation, exposure history, location, and testing are all part of understanding a possible case.
When to check official guidance
Contact a healthcare professional if symptoms follow possible exposure. Seek urgent care for breathing trouble or rapidly worsening illness.
