The beginning symptoms of a hantavirus infection are fever and muscle aches that especially affect the larger muscles of the hips, back and shoulders, according to the Centers for Disease Control and Prevention. People also complain of headaches, chills, dizziness and stomach upset such as nausea and vomiting.
Because there are so few cases of hantavirus infection, the incubation period is not well-known, according to the CDC. The incubation period is the interval between infection by the virus and the symptoms starting to appear, says MedicineNet. Medical experts speculate that this can be between one and five weeks with the hantavirus.
People can contract hantavirus by coming into contact with the droppings or bodily fluids of infected rodents, according to the CDC.
