A Rare Canine Disease, Brucellosis, Spreads to Humans in the UK: What You Need to Know
Brucellosis, a canine disease caused by Brucella canis, has recently been identified in two individuals in the UK. Previously, this disease was only seen in dogs imported into the country. However, since 2020, it has been spreading between local dogs, according to a report released on September 18 by the Human Animal Infections and Risk Surveillance group.
Identification of Human Infections
According to the report, as of July 2023, there have been two laboratory-confirmed cases of B. canis human infection in the UK. One case was identified due to clinical suspicion after the patient presented at the hospital. The second case, although asymptomatic, was detected through follow-up of individuals exposed to positive dogs. Both incidents involved dogs that were not known to be infected at the time of human exposure but later tested positive. This is the first time dog-to-dog transmission of B. canis has been identified in the UK.
