Adult tapeworms probably have a limited survival span outside the host body - not more than several days, if even that long. The adult tapeworms are not able to feed and have no way to re-enter a host. Given their habitat you probably won't encounter one unless it's during a fresh post-mortem.
An ancillary question would be, how long can the tapeworm egg sacs survive outside the host body? The answer to that one may be 'indefinite' - the eggs require no special conditions to survive. They simply lie around waiting to be consumed by fleas in order to begin the next phase of their growth cycle.
Pinworms do not survive for long periods outside the human body. They typically do not live for more than a few weeks in the environment. They require a warm, moist environment to survive and reproduce.
Hepatitis C can live for 1 week outside the body.
I am not sure how long it will live outside the body, but this does not necessarily matter as many people are carriers.
No. HIV needs a host. It does not live long, outside the body.
Hep B can live for up to a week outside the body.
A pinworm infection typically involves hundreds to thousands of pinworms living in the large intestine. These parasites are small, white worms that are usually between 1 to 13 millimeters long.

You can't live without a heart.
Virii like hepatitis actually alter your DNA. Once you have hepatitis, you have it for life. Virii can go through long periods of dormancy where they don't cause harm to internal organs, but can suddenly "switch on" and in the case of hepatitis cause severe damage to your liver. If you think you have been exposed to Hep C it's important to get checked out and then get on a life long treatment regimen.
It can live up to a half hour after ejaculation under the absolute best conditions,
Once it hits air, its (( dead )). It can live inside the body for 5-6 days
It would be measured in a matter of minutes...or until the semen dries up.
