Introduction to Hantavirus Pulmonary Syndrome (HPS)
Small But Deadly
Hantavirus pulmonary syndrome (HPS) has been recognized as a disease only recently in North America. So far, it's also fairly uncommon and the chances of becoming infected are low. However, HPS is potentially deadly and immediate intensive care is essential once symptoms appear.
The Mouse That Roared
Hantaviruses that cause HPS are carried by rodents, especially the deer mouse. You can become infected by exposure to their 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 often ventilation within 24 hours.
Prevention is the best strategy, and it simply means taking some very practical steps to minimize your contact with rodents. HPS is not contagious from person to person in the United States.
