Although uncommon, the virus can also be passed to humans through a rodent bite. Other rodents may also be infected with this virus but in much smaller numbers. The illness usually starts with influenza-like symptoms, a fever greater that 100.5 o F, muscle aches and chills. Other common symptoms are a cough, shortness of breath, nausea and vomiting, diarrhea, and headache. Less common are dizziness or lightheadedness, joint pain, back, chest or abdominal pain, and sweats.
Rare symptoms are a runny nose and sore throat.
The incubation period is not well known in this disease. HPS should be considered in anyone with any of the above symptoms who has had exposure to rodents within the last 42 days. The only treatment so far is supportive. Persons with severe breathing problems are often placed on oxygen and a ventilator. The best course of action is for the affected person to be admitted to an intensive care unit equipped to deal with respiratory distress patients as soon as possible.
