Question

What is the ability to resist a disease called?

Answer 1

The capacity to avoid or minimize the occurrence of illnesses in otherwise susceptible hosts is known as disease resistance. Incomplete penetrance, for example, might be caused by genetic or environmental causes. Illness tolerance is distinct in that it refers to a host's ability to restrict the impact of disease on his or her health. Disease resistance differs between individuals, different races as well as in different species.

Complete answer:
The ability of our body to resist a disease is known as Immunity.
Immunity refers to a multicellular organism's capacity to fight dangerous pathogens. There are both specific and generic components to immunity.
The nonspecific components, regardless of antigenic make-up, function as barriers or eliminators for a wide spectrum of infections. Other immune system components adapt to each new illness they meet and can even produce an immune response which is pathogen specific.
Immunity is the body's ability to defend itself against 'foreign bodies’ and it can also be defined as the ability of our body to differentiate between self and nonself cells. This includes fighting infections, removing dust from the lungs, and destroying cancer cells.
There are two forms of immunity. Innate immunity protects the host against infection but has no memory, thus it does not provide long-term protection.
Adaptive immunity is the second type, and it does have some memory. It does provide long-term protection against some infections.

Note:
The immune system serves an important function: it defends your body against dangerous chemicals, pathogens, and cell alterations that might make you sick. It consists of a variety of organs, cells, and proteins. A variety of items that the body does not recognize as its own might trigger the immune system. Antigens are the scientific term for these substances. Antigens include proteins found on the surfaces of bacteria, fungi, and viruses.
