Also known as: selsema anjing
Selesema anjing ialah jangkitan pernafasan berjangkit disebabkan oleh strain virus influenza A H3N8 dan H3N2. Oleh kerana virus ini agak baharu bagi anjing, kebanyakan anjing tiada imuniti semula jadi, membolehkan penyebaran pantas dalam kumpulan. Penyakit berbeza daripada batuk ringan dan lelehan hidung sehingga demam dan pneumonia. Penyakit teruk dan kematian jarang berlaku tetapi boleh timbul, terutamanya dengan jangkitan bakteria sekunder.
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.
