Tapeworms can live in a host for 5-10 years.

Intracellular pathogens. These types of pathogens rely on living host cells to survive and reproduce, making them more challenging to treat with certain types of medications or treatments.
Aids depends on the right conditions to survive. it will not survive for long outside a live host.
The immune system needs to destroy the pathogens. Other wise the pathogens will multiply in the body of host. The pathogens will multiply by geometrical proportion. With in very short time the pathogens will occupy the whole body. You can no longer survive in that case.
No. HIV needs a host. It does not live long, outside the body.
No
intracellular pathogens can only replicate inside a host cell, whereas extracellular pathogens can replicate independent of the host
The cyst stage allows for the transmission of intestinal parasites from one host to another. These cysts are environmentally resistant and can survive outside the host, facilitating their transfer to a new host through contaminated food, water, or surfaces.
Viruses are obligate intracellular pathogens, meaning they require a host cell to replicate and carry out their life cycle. Outside of a host, viruses lack the necessary cellular machinery and metabolic processes to survive for extended periods, typically becoming inactive or degrading. The duration a virus can survive outside of a host varies by type, with some remaining viable for hours to days under favorable conditions, while others may only last a few minutes. Ultimately, their dependence on hosts for replication limits their viability in the external environment.
The lifespan of pathogens varies significantly depending on the type of organism and environmental conditions. Bacteria can survive from a few hours to several months outside a host, while viruses may last from a few minutes to several days on surfaces. Fungi and parasites also have varied survival rates, often influenced by temperature, humidity, and exposure to disinfectants. Overall, the longevity of pathogens is highly context-dependent.
Prions do not require a host to survive in the traditional sense, as they are misfolded proteins that can exist independently in the environment. They can remain stable and infectious outside of a host for extended periods, often found in contaminated materials. However, to propagate and cause disease, prions need to interact with normal proteins in a host to induce misfolding. Thus, while they can exist outside a host, they need a host for replication and pathogenicity.
