Disease Spotlight: Diseases from Pets

Hantaviruses are a group of viruses that may be carried by some rodents. Some hantaviruses can cause a rare but deadly disease called hantavirus pulmonary syndrome. The disease is called HPS for short.

Seoul Virus is a type of hantavirus. Infection with Seoul virus is known to cause a mild to moderate illness that is rarely fatal.

1-23-17  The Illinois Department of Public Health (IDPH) is reporting six cases of Seoul virus in individuals who had direct exposure to rats in two different Illinois ratteries. Ratteries are facilities where rats are bred. A rattery in Wisconsin purchased rats from the two Illinois ratteries and two Wisconsin residents have also tested positive for Seoul virus. Results of laboratory testing of rats at these facilities are pending. The ratteries are in north-west and east-central Illinois. The affected ratteries have been notified, are cooperating with public health officials, and are no longer selling rats. The virus is not known to spread person to person, therefore the general public is at very low risk. For more information on the safe handling of pet rodents, please see the following links.
