The first symptoms of hantavirus usually appear 1 to 5 weeks after exposure to fresh urine, droppings, or saliva of infected rodents. Initial symptoms closely resemble the flu, including fatigue, fever, and muscle aches, especially in the large muscle groups—thighs, hips, back, and sometimes shoulders. Other early signs can include headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain. As it progresses, symptoms may escalate to include coughing and shortness of breath, which can be an indication of Hantavirus Pulmonary Syndrome (HPS), a severe respiratory disease.
