Which Parvovirus environmental persistence fact is true?

• A. It is destroyed by sunlight quickly
• B. It does not survive long outside a host
• C. It only persists in moist environments for days
• D. It stays on inanimate objects for months

Answer: (D)

Parvovirus environmental persistence is extremely durable. Canine parvovirus is a non-enveloped virus, which makes it resistant to many environmental stresses that would inactivate other viruses. Because of that, it can remain viable on inanimate objects—like kennels, flooring, clothing, toys, and soil—for months, even in the presence of normal weather conditions. This long-lasting presence is why contaminated environments can stay infectious long after the initial exposure, underscoring the importance of thorough cleaning with effective disinfectants and proper quarantine and vaccination to prevent spread. Sunlight and typical outdoor conditions do not reliably inactivate it quickly, so it’s not accurate to say it’s destroyed by sunlight quickly. It’s not limited to moist environments or to only short durations; it can persist across a range of conditions for extended periods. The takeaway is that it can stay on inanimate objects for months.
