Is Parvo only transmitted through the feces, or can it be transmitted through vomit as well?
Say that my pup does have parvo, he has had diarreah all over the lawn. Could he get the parvo again by sniffing the lawn? If so, how can I desinfect a whole yard? Should I dispose of any of his items that cannot be washed with bleach?

Once they have had parvo, they are immune, at least to the strain they had. I would disinfect all his food and water dishes, bedding, crate, etc. just in case it was a bacterial thing. Parvo can be spread by contact with any infected body fluid, most commonly stool has the most virus particles, because it contains blood. Here in Oklahoma, we almost never see Parvo in the winter, but it's endemic in summer. Most of the vets I know suspect that flies are the biggest culprit in spreading it. A fly lands on infected stool, then walks across your puppies' water bowl, or bites their ear, etc.

Since parvo is a virus, they will always carry the Parvovirus and will always test positive for Parvovirus.
However, other pups that come into your yard (that don't have a full set of vaccs) are more susceptible to contracting Parvo from your yard/contaminated items. Parvovirus stays alive and active in your yard for around 6-9 months - though the actual lifespan has been debated.

I do not know the basis for the test, but if it is a test for antibodies to Parvo, the antibodies should persist long after the infection is cleared.

Actually, I called the Auburn Vet just to double check, and they agreed.
When a puppy has Parvo and recovers from its symptoms (after vet care), it still tests positive as it still carries the virus.
It's the same thing with humans as well. Viruses are never killed in your system - you still carry them.
"As there is no cure for any virus, treatment for parvo is mostly that of supporting the different systems in the body during the course of the disease."

Shelby,
Not to be disagreeable, but that's not how human ( or animal ) medicine goes ( unless I slept ithrough all those classes in PA school ).
If viruses weren't *killed* to a low enough level, a patient would remain ill. It's the body fighting and killing the virus load that makes the symptoms abate. So viruses are indeed "killed in you system".
Your bodies immune system kills both the virus outside of cells and the infected cells cells themselves - that's just plain ol' science.
And the tests after the illness test for a "titer" of antibodies made by the body to fight the disease - these show that the body was exposed to the virus, they don't reveal that the virus is still present in the body.
And as far as ""As there is no cure for any virus" - apparently those writers have never heard of Acyclovir ( which is used to inhibit the replication of the Herpes virus ) and the newer HIV drugs, which inhibit the replication of the HIV virus.

I did a little reading since I read the first posts. Parvo is related to Adeno-associated virus, and I am not very familiar with that virus. At least some of the tests fpr Parvo are direct detection of viral particles, so persistant infection results in the positive test.
As far as the more global statement you made about humans, I am fairly certain that this depends on the virus. In humans, Hep B and C virus, herpes, variola zoster (chicken pox), HIV and papiloma viruses are examples of viruses that persist in infected people. Influenza, Hep A and cold viruses are not persistant, and I also believe that some very deadly viruses like the VEE, EEE and dengue fever are completely cleared from the body and give rise to protective immunity (assuming you survive). I am rusty on my virology, but checked some of this on the CDC site.
