This hantavirus symptoms guide explains early illness, severe warning signs, the differences between HPS and HFRS, and why exposure history is important when seeking medical care.
Hantavirus symptoms often begin one to eight weeks after exposure, depending on the virus and disease pattern. Early hantavirus symptoms can resemble other infections, so possible rodent exposure, travel, or close contact with a confirmed Andes virus case should be mentioned to clinicians.
Common hantavirus symptoms include fever, headache, muscle aches, fatigue, abdominal pain, nausea, vomiting, or diarrhea. These symptoms can progress quickly in severe disease.
WARNING SIGNS
Severe hantavirus symptoms depend on the syndrome. HPS affects the lungs and heart; HFRS affects kidneys and blood vessels.
Hantavirus symptoms in HPS can include cough, shortness of breath, fluid in the lungs, low oxygen, and shock.
Hantavirus symptoms in HFRS can include low blood pressure, bleeding problems, kidney complications, and acute kidney failure.
Seek medical care quickly if hantavirus symptoms develop after rodent exposure, cleaning enclosed spaces, or contact with a confirmed Andes virus case.
Hantavirus symptoms are not enough to diagnose infection by themselves. Testing decisions depend on symptoms, exposure history, timing, and local public-health guidance.
