yes it a disease to your body and is what causes a cold
Stomache virus
a pathogen is any thing (usualy a bacteria, virus, or protein based) that can cause a disease
Prions, which require an electron microscope to be seen. These are the causative agent in bovine spongiform disease, "mad cow" disease. Their incredibly small size allows them to cross the blood/brain barrier.
Bacteria cells. They are the smallest living thing on Earth (known to man).
It will have no direct effect on the organism ::x: It will cause a disease in the organism.

yes
HIV is the virus. AIDS is the disease caused by the virus. (So HIV is not actually a disease per se.) As an analogue - the H1N1 virus can cause the flu.
Immediate cause is the first cause identified when a person is suffering from a disease. For example, if a baby is suffering from loose motions,we can say that the cause of the loose motions is an infection with a virus. So, the immediate cause of the disease is virus.
Respiratory tract
Any virus can usually cause a severe disease or death.
A virus does not cause a disease but it will weapon your immune system and make you more susceptible to contracting diseases.
Prevent it from occuring.
It doesn't cause any disease. It protects against the chicken pox (varicella-zoster) virus.
Smallest block that makes up a living thing is the cell, although some debate that virus, which is much smaller than a cell, is a living thing.
The ability of a virus to cause disease is referred to as its "pathogenicity." This term describes the virus's capacity to infect a host and lead to harmful effects, which can vary in severity depending on factors such as the virus's characteristics and the host's immune response. Pathogenicity is often assessed in terms of the virus's virulence, which indicates the degree of harm it can cause.
