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.
In biology, a pathogen (Greek: πάθος, pathos "suffering", "passion" and -γενής, -genēs "producer of"), in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. [1] The term pathogen came into use in the 1880s.
Tetracycline-class antibiotics No Respiratory syncytial virus (RSV) Respiratory syncytial virus infection A variety of laboratory tests Treatment for RSV infection is focused primarily on supportive care. Under research [33] Rhinosporidium seeberi: Rhinosporidiosis: No Rhinovirus: Rhinovirus infection No Rickettsia species Rickettsial infection No
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
A food safety hazard is any biological, chemical, or physical property that may cause a food to be unsafe for human consumption. Identify critical control points A critical control point (CCP) is a point, step, or procedure in a food manufacturing process at which control can be applied and, as a result, a food safety hazard can be prevented ...
Chain of infection; the chain of events that lead to infection. There is a general chain of events that applies to infections, sometimes called the chain of infection [14] or transmission chain. The chain of events involves several steps – which include the infectious agent, reservoir, entering a susceptible host, exit and transmission to new ...
Generally, diseases outlined within the ICD-10 codes A00-B99 within Chapter I: Certain infectious and parasitic diseases should be included in this category. Infectious diseases are diseases caused by biological agents, which can be transmitted to others, rather than by genetic, physical or chemical agents.
A conclusive determination of a causal role of an infectious agent for in a particular disease using Koch's postulates is desired yet this might not be possible. [ 1 ] The leading cause of death worldwide is cardiovascular disease , but infectious diseases are the second leading cause of death worldwide and the leading cause of death in infants ...
