In Colorado, more than 35 individuals have been referred for post-exposure rabies treatment after a rabid puppy was identified at a rescue adoption event, though no human cases have been confirmed. State health officials are urging attendees of the event to seek screening, as rabies is nearly always fatal once symptoms manifest. Following the incident, 12 puppies from the infected puppy's litter were euthanized, with one additional puppy testing positive for rabies and 10 testing negative, raising concerns about the necessity of such drastic measures. The head of the rescue group expressed heartbreak over the euthanasia of the puppies, emphasizing that the remaining puppies could still carry the virus despite negative tests. Health officials continue to investigate and assess potential exposures, highlighting the urgency of the situation. Meanwhile, rabies-positive animals have also been reported in several counties in West Michigan, underscoring ongoing public health concerns regarding rabies.
