ANVH EP-81 Parvovirus alarm in Vancouver 犬細小病毒爆發警報
Canine parvovirus (CPV) is a highly contagious and often life‑threatening viral disease in dogs, especially puppies. It causes severe gastrointestinal illness, rapid dehydration, and can be fatal without prompt veterinary care.
CPV Is
• A highly contagious virus that spreads through infected f***s and contaminated environments.
• Primarily affects puppies 6–20 weeks old, but unvaccinated adults can also get sick.
• Causes acute hemorrhagic gastroenteritis and sometimes myocarditis in very young pups.
• The virus mutates quickly, leading to new variants that continue to circulate globally.
How It Spreads
• Direct contact with infected dogs
• Contact with contaminated surfaces (floors, soil, shoes, bowls, hands)
• The virus survives for months in the environment and is resistant to many disinfectants.
Clinical Signs
Common symptoms include:
• Severe vomiting
• Profuse, often bloody diarrhea
• Lethargy, fever, anorexia
• Rapid dehydration
• Abdominal pain
Any puppy with these signs should be treated as an emergency.
Treatment
There is no antiviral cure, but aggressive supportive care dramatically improves survival:
• IV fluids and electrolyte correction
• Antiemetics
• Antibiotics to prevent secondary bacterial infection
• Nutritional support
• Isolation to prevent spread
• Some clinics now use monoclonal antibody therapy, which may improve outcomes.
Prevention
• Vaccination is extremely effective and the best protection.
• Puppies need a series of vaccines every 3–4 weeks until at least 16 weeks old.
• Avoid dog parks or unknown dogs until fully vaccinated.
• Use bleach (1:30 dilution) to disinfect contaminated areas.
If You’re in Richmond, BC and dealing with a suspected parvo case, emergency care is critical.

犬小病毒(CPV) 是一種高度傳染、可能致命的病毒性疾病,最常見於尚未完成疫苗接種的幼犬。發病速度快、症狀嚴重,需要立即就醫。
什麼是犬小病毒?
• 透過受感染糞便與受污染環境快速傳播
• 最常見於 6–20 週齡幼犬

🏥 如何治療?
目前沒有直接殺死病毒的藥物,但積極治療能大幅提高存活率:
• 靜脈輸液與電解質補充
• 止吐與腸胃保護
• 抗生素預防繼發感染
• 早期營養支持
• 嚴格隔離
• 部分醫院提供 單株抗體療法,可改善預後
