Infection Control and Prevention – Rationale / Explanations:-
1.Standard precautions are meant to reduce the risk of transmission of blood borne and other pathogens from both recognized and unrecognized sources.
•They are the basic level of infection control precautions which are to be used, as a minimum, in the care of all patients.
2.Any substance that inhibits the growth and replication of a bacterium or kills it outright can be called an antibiotic.
•They either prevent the reproduction of bacteria, or they kill the bacteria, for example by stopping the mechanism responsible for building their cell walls.
3.Antibiotics are a type of antimicrobial designed to target bacterial infections within (or on) the body.
•Systemic means affecting the entire body, rather than a single organ or body part. For example, systemic disorders, such as high blood pressure, or systemic diseases, such as the flu, affect the entire body.
•An infection that is in the bloodstream is called a systemic infection.
4. Negative-pressure airflow is used for airborne precautions.
Pulmonary TB is spread by airborne transmission and therefore negative-pressure airflow protection is required
5. A hospital-acquired infection (HAI), also known as a nosocomial infection, is an infection that is acquired in a hospital or other health care facility.
• To emphasize both hospital and nonhospital settings, it is sometimes instead called a health care–associated infection (HAI or HCAI)
6. An opportunistic infection is an infection caused by pathogens (bacteria, viruses, fungi, or protozoa) that take advantage of an opportunity not normally available, such as a host with a weakened immune system, an altered micro biota (such as a disrupted gut micro biota), or breached integumentary barriers
7.Cycle of Infection Transmission:-
The way to stop germs from spreading is by interrupting this chain at any link.
9. Clostridium difficile infection (CDI) is due to a toxin-producing bacteria that causes a more severe form of antibiotic associated diarrhea.
•The disease ranges from mild diarrhea to severe colon inflammation that can even be fatal.
•C. difficile is a gram positive bacterium
16.Scabies is spread by prolonged skin-to-skin contact with a person who has scabies.
• Scabies sometimes also can be spread by contact with items such as clothing, bedding, or towels that have been used by a person with scabies, but such spread is very uncommon unless the infested person has crusted scabies
17. Acute bronchitis due to infection is often transmitted through microscopic, airborne droplets that contain a germ and are produced when someone speaks, sneezes, or coughs.
• It can also be transmitted by shaking hands or other types of physical contact with an infected person
18. The hepatitis A virus is transmitted primarily by the faecal-oral route; that is when an uninfected person ingests food or water that has been contaminated with the faeces of an infected person
