Parvo season refers to the times of year when canine parvovirus infections are considered more prevalent.
Defining Parvo Season
In the world of veterinary medicine, Spring and Fall are considered "Parvo Season." During these periods, there tends to be an increased risk for dogs contracting this serious illness.
Understanding Canine Parvovirus
Canine parvovirus is a highly contagious, infectious, gastrointestinal virus. It spreads easily through contact with contaminated feces, environments, or people. The virus is known for causing severe symptoms like vomiting, diarrhea (often bloody), lethargy, and loss of appetite in dogs, particularly puppies.
Why Spring and Fall are Considered Parvo Season
The designation of Spring and Fall as parvo season is linked to several factors that may contribute to increased transmission during these times:
- Increased Outdoor Activity: Warmer weather in spring and cooler, pleasant temperatures in fall often lead to dogs spending more time outdoors in parks, dog runs, and other public areas where the virus might be present.
- Susceptible Populations: The reference highlights specific groups of dogs most vulnerable during this time:
- Those canine that are not fully vaccinated.
- Dogs that have never been vaccinated.
- Puppies just weaned and starting out without their full antibodies on board.
- Breeding Cycles: Spring and Fall can align with periods when new litters of puppies (the most vulnerable population) are being weaned and potentially exposed to the virus as they start to explore the world or move to new homes.
Because the virus is hardy and can survive in the environment for long periods, periods of increased dog activity and susceptible puppy populations contribute to higher case numbers during these seasons.
