Infection is the process by which an infectious agent passes from one organism to another.

The given statement is true.

An infection is produced by the entry of an infectious agent into the body of an organism, such as a virus, bacterium, or fungus. This agent can be found in the environment, on surfaces, or in other species that carry it. When the agent enters the body, it has the potential to proliferate and do harm.

There are various processes involved in the infection process. The infectious agent must first make contact with the host. This can happen through direct contact, such as touching an infected person or item, or by indirect contact, such as breathing the agent-containing airborne particles.

Once within the host's body, the agent can begin to grow and spread. The agent might enter the body via the skin, respiratory tract, digestive system, or other pathways. The agent, once inside the body, can cause harm to the host's cells, tissues, and organs.

The immune system of the host may identify the infectious pathogen and seek to fight it off. However, in other situations, the toxin can elude detection and continue to injure. This might result in the emergence of symptoms such as fever, coughing, and exhaustion.

If the infectious agent is not removed, it will reproduce and spread to other sections of the host's body or to other organisms. Infections can be transmitted from one organism to another by contact with body fluids, surfaces, or other ways. As a result, knowing the infection process is crucial to understanding how infectious illnesses spread and how they might be treated.
