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.
I am not a doctor, so I dont know, and if you are not a doctor/specialist/professional, then dont act like you do, opinion needs to be presented as an opinion, not fact.
This what internet does, gives you so much unverified info. You dont know who is writing that "fact" while itching his/her anus, and posting his/her "facts" online.
So to my opinion, a pinworm cannot live outside of persons body for "weeks", common sense tells you that and parasite needs a certain environment to survive, and facts like "it lives on clothing and carpet for weeks" is just trash info without any proven data...
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.
Sperm cannot live for very long outside of the body
E. coli bacteria can live outside of the body for long durations of time. This is especially true when there are conditions available that allow for these organisms to eat and multiply.
You can't live without a heart.

The lifespan of germs varies depending on the type of germ and the surrounding environment. Some germs can survive for days or even weeks on surfaces, while others may only survive for a few minutes. Regular cleaning and disinfection can help reduce the spread of germs.
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.
There are many types of bacteria some of which don't need to live inside another organism.
for years in soil and other surfaces.
