Grippe Canine (Influenza) à Macau : Ce Que les Propriétaires Doivent Savoir
La grippe canine est une infection respiratoire contagieuse. Découvrez les symptômes, les options de traitement et comment protéger votre chien à Macau.
Canine influenza (dog flu) is a contagious respiratory disease caused by specific Type A influenza viruses — H3N8 and H3N2. Unlike human flu, dog flu is not seasonal and can spread year-round. Most dogs have no natural immunity, meaning nearly 100% of exposed dogs become infected. While most cases are mild, some dogs develop severe pneumonia.
Points Clés
- Canine influenza spreads through coughing, sneezing, and contaminated objects (bowls, leashes, clothing)
- Nearly 100% of exposed dogs become infected — most have no prior immunity
- Symptoms include coughing, nasal discharge, fever, lethargy, and reduced appetite
- About 20% of infected dogs show no symptoms but can still spread the virus
- Dogs that visit groomers, daycares, dog parks, or boarding facilities are at highest risk
- A canine influenza vaccine is available and recommended for social dogs
Understanding Dog Flu
Canine influenza viruses (CIV) are different from human influenza viruses — dogs cannot catch human flu and humans generally cannot catch dog flu. The virus causes an upper respiratory infection similar to kennel cough but often more severe. The incubation period is 2-4 days, and dogs are most contagious during this time before showing symptoms. The virus survives on surfaces for up to 48 hours.
Mild vs Severe Cases
About 80% of dogs experience mild symptoms: persistent cough (wet or dry), nasal discharge, sneezing, lethargy, and reduced appetite lasting 10-14 days. About 20% develop severe disease with high fever (over 40°C), difficulty breathing, and secondary bacterial pneumonia requiring hospitalization. Fatal cases are rare (less than 5%) but do occur, especially in very young, elderly, or immunocompromised dogs.
Prevention Strategies
The canine influenza vaccine reduces severity and duration of illness even if it doesn't completely prevent infection. It's recommended for dogs that regularly interact with other dogs — at groomers, daycares, parks, or boarding facilities. The vaccine requires two initial doses 2-4 weeks apart, then annual boosters. Good hygiene — washing hands between handling different dogs, disinfecting shared equipment — also helps prevent spread.
Quarantine and Recovery
Dogs diagnosed with canine influenza should be isolated from other dogs for at least 21 days (even after symptoms resolve, they can still shed the virus). Recovery typically takes 2-3 weeks with supportive care: rest, fluids, and sometimes antibiotics for secondary infections. Clean and disinfect all items the sick dog contacted. Notify any facilities where your dog recently visited so they can take precautions.
