Canine Distemper Outbreak in Aguaí, SP: Veterinarian Warns of Unvaccinated Dog Deaths

A severe outbreak of canine distemper is occurring in Aguaí, a city in São Paulo state, Brazil, leading to the deaths of unvaccinated dogs. Veterinarian Henrique Nascimento Pozer, founder of Projeto Jurema, described the situation as an "outbreak," reporting that he has rescued over 20 dogs with distemper in the past 30 days. Of these, 12 were in advanced stages of the disease and required euthanasia due to incurable conditions. Canine distemper is a highly contagious viral infection that primarily affects unvaccinated puppies and immunocompromised dogs, impacting their respiratory, digestive, and nervous systems. Symptoms include difficulty moving, respiratory issues, pneumonia, eye and nasal discharge, and can ultimately be fatal. The veterinarian emphasized that these deaths could be prevented with timely vaccination and highlighted a lack of public policies for animal welfare, including preventive vaccination, spaying/neutering, and rescue resources. While some dogs, like Lili and Branquinho, have survived with treatment and support, many succumb to the advanced stages of the illness. The Prefeitura de Aguaí stated they had not been officially notified of the distemper cases but plan to issue a decree requiring notification from caregivers, clinics, and NGOs to better track and control the disease. The city also has an agreement with the Public Prosecutor's Office to assist sick animals, with contracted companies to provide services. Canine distemper is responsible for an estimated 20% of dog deaths annually and is transmitted through inhalation or direct contact with viral particles, affecting only canines. Prevention involves a vaccination schedule starting at 45 days old, with booster shots.
