Polly,
You're right about certain viruses clearing completely from the body - other "hide" in the body ( some being detectable by titer levels, some not ). They may become symptomatic again during episodes of immuno-suppresion.
But parvo has been reported to be a "clearing" virus with only a titer level to reveal it's previous presence ( think if the parvo virus persisted in dogs that had been through their clinical course, most dogs would have so much chance for contact and infection that the death rate from it would be even higher than it already is. <img src="/ubbthreads/images/graemlins/frown.gif" alt="" /> )
Another illustration of Parvo being "cleared" from the body - have their been any cases of a dog that previous had Parvo having a reoccurrence during an episode of immuno-suppresion? None to my knowledge ( but I don't know that for certain )
I don't mind being disagreed with, but every medical site I have since accessed has all said the same thing, "a virus cannot be removed/killed from the body."
I know there are medications that inhibit the replication of, but that does not mean the virus is not still present in the body.
A dog that had parvo as a puppy will have to be treated by a vet, and while the dog may never show signs of parvo again (I can't recall any documentation stating such), the parvo is still present in the body...from what I'm reading.
wouldn't it be nice if every single publication online and offline (and I'm not talking about random commercial websites) would say the same thing about things as serious as health/medicine as far as basic facts?
This may sound off-the-wall but, How long does Parvo virus live in feces? Does it have a dormant period? All you hear from people is Socialize your pup. Doesn't this increase the chance of contracting Parvo or other diseases?

As the owner of a Rottie that survived a bout with Parvo let's just say it was a learning experience. Parvo virus can lay dormant in just about any setting, grass, dirt, carpet from 6-9 months, and survive both extreme heat and cold. It can be carried on shoes and clothing by simply walking through contaminated urine or feces. While socialization is needed it can still be accomplished in a controlled setting.

There are many classes of viruses, and each class has a different method of replication. Some, like retroviruses (such as HIV) integrate into the genome of the infected cells, and new virus is shed from these cells. It also infects some long lived cells like macrophages. This is why the virus is never cleared from the patient, even with the modern dugs that inhibit replication. However, I think that these drgs are given to health care workers after a needle stick to reduce establishing the viral infection.
Other viruses are lytic and always kill the infected cells. These are more readily controlled by the immune system, as antibodies bind to and filter viral particles, and T cells recognize viral proteins, and kill virally infected cells before they have a chance to release more virus.
