The National Park Service over the weekend said it has warned visitors of parks of the disease. Hantavirus pulmonary syndrome begins much like a flu, with muscle aches and a fever, followed by shortness of breath and coughing. Last month Vermont became the 31st state to confirm a case. Dr. Harvey Artsob of the Canadian Science Center for Human and Animal Health in Winnipeg, Manitoba, said all confirmed cases of the virus in Canada have been in the western provinces. It becomes a surveillance phenomenon, like the plague.
Physicians here think about it because they have cases nearly every year.
Tell us what you think.
