Hantaviruses that cause HPS are carried by rodents, especially the deer mouse.
Persons can become infected by exposure to mouse droppings, and the first signs of sickness (especially fever and muscle aches) appear 1 to 5 weeks later, followed by shortness of breath and coughing.
Once this phase begins, the disease progresses rapidly, necessitating hospitalization and immediate intensive care.
There have only been 24 cases in Oregon (pdf) between 1993 to date.
What is required?
Health Care Providers and Clinical Laboratories
Health care providers and clinical laboratories are required by law to report cases and suspect cases of hantavirus to local health departments within one week of identification.
For Local Health Departments
