Viruses are similar to parasites because both require a host to survive and both destroy the cells in which they multiply (cause harm to the host).
Viruses are often referred to as parasites because they depend entirely on a host cell to replicate and carry out their life processes, similar to how parasites rely on a host for survival and reproduction. Unlike living organisms, viruses lack the cellular machinery and metabolic functions necessary for independent life, making them obligate parasites. They invade host cells, hijacking their machinery to produce new viral particles, which can lead to disease in the host. This parasitic behavior underscores their reliance on living organisms for their existence.
Immunity
Pathogens. These are typically bacteria, viruses, fungi, or parasites that can cause disease by invading the body's tissues. Common examples include influenza viruses, E. coli bacteria, and malaria parasites.
Viruses, Bacterial, Parasites, Fungal, Worms and Protozoas which one is the smallest?
Viruses differ from bacteria, fungi, and parasites in that they cannot reproduce independently; they require a host cell to replicate. While bacteria and fungi can divide and reproduce on their own through processes like binary fission or budding, viruses hijack the host's cellular machinery to produce new viral particles. Additionally, parasites are typically multicellular organisms that can reproduce sexually or asexually within or outside a host, whereas viruses are acellular and rely entirely on their host's biological processes for replication.
Parasites can carry and transmit viruses, but they do not "cause" them.
Viruses
No; viruses are sub-Cellular 'virons', while parasites are frequently multi-cellular organisms.
viruses are considered parasites (obligate parasites) because they cannot exist on their own. they need the host cell's machinery to reproduce so they cannot "survive" (technically not living) outside the cell.

Because viruses can not reproduce or produce protein without a host cell
They both destroy the cells that they attack.
Immunity
no. . . Because parasites and viruses can only grow on living matters... There may be saprophytes and bacteria growing in your food. . . Even parasites and viruses can be there but can not grow. .
