a virus can ony reproduce inside a living cell that surves as a host. A Host is living thing that a virus or parasite lives on or in . Using a host's cell as a tiny factory , the virus forces the host to make viruses rather than healthy new cells.
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.
Viruses do not cause diseases in the host. Why? Well, the host is already causing the virus so it is IMPOSSIBLE for another virus to be cause in the host.
Stomache virus
yes
It kills the host bacteria. I don't believe it occurs in eukaryotic cells.
A latent virus remains dormant in the host cell without causing symptoms, but can reactivate later to cause disease. An active virus continuously replicates and causes symptoms, leading to an active infection. Both types of viruses can cause disease, but latent viruses have periods of inactivity while active viruses are constantly causing symptoms.
Pathogenic means "having the ability to cause disease".
The term "host of disease" refers to an organism, typically a human or animal, that harbors a pathogen, such as a virus, bacterium, or parasite, which can cause illness. The host provides the necessary environment and resources for the pathogen to survive, replicate, and potentially spread to others. Understanding the relationship between the host and the disease is crucial for developing effective treatments and prevention strategies.
A micro-organism, such as a bacterium, a virus or a fungus, that invades a host and causes a disease is called a pathogen.
A virus that kills its host is said to be virulent. Virulent viruses can cause serious illness or death in their host organisms.
One example of a virus that doesn't immediately affect a host cell's function is the herpesvirus. After initially infecting cells, herpesvirus can remain dormant in the host's body for years without causing symptoms. It can later reactivate and cause disease.
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.
