Also known as: gripa câinilor
Gripa canină este o infecție respiratorie contagioasă cauzată de tulpinile de virus gripal A H3N8 și H3N2. Deoarece virusul este relativ nou pentru câini, majoritatea nu au imunitate naturală, ceea ce permite răspândirea rapidă în grupuri. Boala variază de la tuse ușoară și secreție nazală până la febră și pneumonie. Boala severă și decesul sunt rare, dar pot apărea, în special în cazul infecției bacteriene secundare.
Canine influenza, or dog flu, is a contagious viral respiratory infection caused by influenza A subtypes H3N8 and H3N2. It can resemble kennel cough but is a distinct viral disease.
The virus spreads through respiratory droplets, contact, and contaminated surfaces. Outbreaks are common in shelters, kennels, and daycare facilities. The H3N2 strain can also infect cats.
Most dogs show a persistent cough, nasal discharge, sneezing, lethargy, and reduced appetite. Some develop high fever, and a minority progress to pneumonia with labored breathing.
PCR testing of nasal or throat swabs early in illness confirms infection, while paired blood tests can detect antibodies later. Radiographs assess lung involvement.
Care is supportive: rest, fluids, and good nutrition. Antibiotics treat secondary bacterial infection, and severe cases may need hospitalization. Recovery usually takes two to three weeks.
Vaccines against H3N8 and H3N2 are available and recommended for at-risk dogs. Isolating sick dogs and disinfecting shared areas limit outbreaks.
