The officials at Colorado Department of Public Health and Environment have confirmed four cases of pneumonic plague in Adams County, Colorado. The officials have claimed that the infection is very similar to an infection that caused death of a dog. According to the officials of Colorado Department of Public Health and Environment, fleas from a rabbit or prairie dog may have infected the dog.
After giving treatment, all four have reportedly recovered from the disease. All of them were given antibiotics and the contagion has been curbed since then.
