A human case of plague was reported in Pueblo County, Colorado, according to health departments in the area. The Pueblo Department of Public Health and Environment (PDPHE) and the Colorado Department of Public Health and Environment are currently investigating the source of the infection.
Plague is a bacterial disease caused by Yersinia pestis that can be transmitted to humans through bites from infected fleas, contact with infected animal corpses, or inhalation of respiratory droplets from an infected animal or human. Symptoms include sudden chills, fever, severe headaches, muscle aches, nausea, swollen lymph nodes and vomiting.
Individuals can protect themselves from plague infection by eliminating potential rodent nesting spaces around their homes and properties. This includes removing brush and rock piles that provide hiding places for rodents. Additionally, avoiding contact with dead animals, using insect repellent to prevent flea bites, keeping pets away from rodent habitats, treating pets for fleas regularly, and storing pet food in rodent-proof containers are recommended precautions.
Plague can be treated successfully with antibiotics if diagnosed promptly. However, it is important to note that complications or even death can occur if not treated early.
According to the PDPHE, there were 10 cases of plague in animals reported by the state health department in 2021. Six of those cases involved domestic animals.
Plague naturally occurs in semi-rural to rural areas of Western states like Arizona, California, Colorado and New Mexico. Commonly infected animals include chipmunks, mice, prairie dogs, rabbits, squirrels, voles and wood rats.
