Possible Plague Case in Pueblo County: Health Officials Investigate

In Pueblo County, health officials are currently examining a potential case of plague after an individual’s preliminary test indicated a positive result. The Pueblo County Department of Public Health and Environment has refrained from disclosing any personal details about the patient, including their current health status. Plague, albeit a serious illness, can be effectively treated with antibiotics if diagnosed early. However, if left untreated, it can result in a high fatality rate as the disease progresses.

Understanding Plague and Its Transmission

Plague is a rare but severe infectious disease caused by the bacterium Yersinia pestis. While the disease can spread from person to person, this mode of transmission is relatively uncommon. Typically, individuals contract the plague through bites from infected fleas or by coming into contact with sick or deceased animals. The bacterium circulates frequently among prairie dogs and other small mammals in Colorado, making it a significant public health concern in the region.

How Plague Spreads in Nature

  • Flea Bites: The primary mode of transmission is through the bite of an infected flea. These fleas often live on rodents such as rats, squirrels, and prairie dogs.
  • Animal Contact: Direct contact with the bodily fluids or tissues of infected animals can also lead to infection.
  • Human-to-Human Transmission: Although rare, plague can spread from person to person through respiratory droplets when an infected individual coughs.

Preventive Measures

Given the serious nature of the disease, taking preventive measures is crucial. Here are some steps to minimize the risk of plague:

Personal Protective Measures

  • Avoid Contact with Wild Animals: Refrain from handling sick or dead animals. If contact is unavoidable, use protective gloves.
  • Use Insect Repellent: Apply repellents that contain DEET to ward off fleas when in areas known to have plague.
  • Keep Pets Safe: Prevent pets from roaming freely and using flea control products on them.

Community and Environmental Measures

  • Control Rodent Populations: Implement measures to reduce rodent habitats around homes, such as clearing brush and storing food securely.
  • Public Education: Inform communities about the risks of plague and ways to prevent it.

Historical Context and Recent Cases

Colorado has documented 72 human cases of plague from 2005 to 2021, with 11 of these resulting in death. In the previous year, at least one individual contracted the disease within the state. These statistics highlight the persistent threat posed by plague and the importance of continuous vigilance.
