Although fecal–oral transmission is usually discussed as a route of transmission, it is actually a specification of the entry and exit portals of the pathogen, and can operate across several of the other routes of transmission. [1] Fecal–oral transmission is primarily considered as an indirect contact route through contaminated food or water.
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.
Physicians who desire to become infection control practitioners often are trained in the context of an infectious disease fellowship. Training that is conducted "face to face", via a computer, or via video conferencing may help improve compliance and reduce errors when compared with "folder based" training (providing health care professionals ...
For example, the Coordinating Center for Infectious Diseases had 600 employees, while the Office of Infectious Diseases had 12. [12] There were initially three Deputy Director offices, which was increased to four in 2018: [13] [14] The Deputy Director for Infectious Diseases succeeded the Coordinating Center for Infectious Diseases.
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 ...
Typical sites of virus entry into the body: The first steps of viral infection is determined by the site at which the virus implants into the body. This would subsequently dictate the mechanisms of viral pathogenesis. Transmission from a host with an infection to a second host; Entry of the virus into the body; Local replication in susceptible ...
The bird flu outbreak has taken concerning turns, with more than 60 human cases confirmed. Experts outlined four signs that the virus is going in the wrong direction.
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 ...
