It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. [1] [2] They may either kill or inhibit the growth of bacteria. A limited number of antibiotics also possess antiprotozoal activity.

The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
Antibiotic prophylaxis refers to, for humans, the prevention of infection complications using antimicrobial therapy (most commonly antibiotics). Antibiotic prophylaxis in domestic animal feed mixes has been employed in America since at least 1970.
Infection prevention and control is the discipline concerned with preventing healthcare-associated infections; a practical rather than academic sub-discipline of epidemiology. In Northern Europe , infection prevention and control is expanded from healthcare into a component in public health , known as "infection protection" ( smittevern ...
As bacterial and viral infections can both cause the same kinds of symptoms, it can be difficult to distinguish which is the cause of a specific infection. [11] Distinguishing the two is important, since viral infections cannot be cured by antibiotics whereas bacterial infections can. [12]
Dysentery results from bacterial or parasitic infections. Viruses do not generally cause the disease. [ 10 ] These pathogens typically reach the large intestine after entering orally, through ingestion of contaminated food or water, oral contact with contaminated objects or hands, and so on.
Transmission-based precautions are infection-control precautions in health care, in addition to the so-called "standard precautions". They are the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important pathogens, which require additional control ...
