This table represents changes in the infection rate of domestic dogs. Due to the large number of stray dogs sheltered and effective management in endemic counties, the number of infection sources has decreased significantly, and the weighted dog infection rate, which represents the prevalence of endemic counties, has been significantly reduced.
