how is parvo spread

Parvo spreads mainly through contact with infected poop or vomit, and in dogs it can also spread indirectly through contaminated shoes, hands, bedding, bowls, floors, grass, or soil. For humans, the common parvovirus B19 spreads through respiratory particles, blood or blood products, and from mother to baby during pregnancy.

In dogs

Canine parvovirus is highly contagious and can survive in the environment for a long time, which is why a dog does not need to meet an infected dog directly to catch it. It can spread when an unprotected dog sniffs, licks, or steps in contaminated material and then ingests the virus. The virus is not airborne, so it does not spread like a cough in the air.

In people

Parvovirus B19 spreads person to person, mostly through respiratory particles, and less commonly through blood exposure or during pregnancy from parent to baby. People are usually most contagious early in the illness, before the classic rash appears.

Prevention

• Keep dogs up to date on vaccination.

• Avoid contact with dog feces and vomit, and clean contaminated areas carefully.

• Wash hands well and disinfect shared surfaces.

• For human parvovirus, use good respiratory hygiene like covering coughs and sneezes.

If you mean dog parvo , the big risk is contaminated environments; if you mean human parvovirus B19 , it spreads mainly through respiratory particles.
