Symptoms of hantavirus usually occur in two
phases. During the first 3 to 7 days of illness, symptoms
typically include fever; chills; headache; muscle pain in the
shoulders, lower back, and thighs; nausea; vomiting; diarrhea;
and dizziness.
After the first 3 to 7 days of illness, there is usually an
abrupt onset of respiratory symptoms (such as coughing and
shortness of breath resulting from swelling
in the lungs and severe oxygen deficit). These symptoms
progress rapidly and require prompt medical intervention.
The incubation period for hantavirus may be 1 to 6 weeks after
exposure to infected rodents, their saliva, or excretions, but
has not been established definitely.
