Among patients and health care personnel, microorganisms are spread to others through four common routes of transmission: contact (direct and indirect) , respiratory droplets, airborne spread, and common vehicle.
What is the most common form of transmission of microorganisms?
What is DIRECT AND INDIRECT DISEASE TRANSMISSION? Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.
What is the most common mode of infection transmission in the healthcare environment?
Contact is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect. An example of contact transmitted microorganisms is Noroviruses which are responsible for many gastrointestinal infections.
What are the three main routes of transmission of microorganisms in healthcare?
The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne . Some microorganisms can be transmitted by more than one route.
What is the most common source of transmission of microorganisms in the operating room?
Direct and indirect contacts are the most significant and frequent methods of hospital infection transmission.
What are the main modes of disease transmission?
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the 6 modes of transmission?
The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle . The portal of entry is the means by which the infectious microorganisms gains access into the new host. This can occur, for example, through ingestion, breathing, or skin puncture.
What are the common methods of transmission of diseases Class 9?
- Airborne transmission. Some infectious agents can travel long distances and remain suspended in the air for an extended period of time. ...
- Contaminated objects. ...
- Food and drinking water. ...
- Animal-to-person contact. ...
- Animal reservoirs. ...
- Insect bites (vector-borne disease) ...
- Environmental reservoirs.
What diseases are spread through direct contact?
- Conjunctivitis (Pink-eye)
- Creutzfeldt-Jacob (CJD)
- Ebola Virus Disease.
- Erythema Infectiosum (Fifth disease)
- Impetigo.
- Pediculosis (Head lice)

Where can microorganisms live and multiply?
Germs live everywhere . You can find germs (microbes) in the air; on food, plants and animals; in soil and water — and on just about every other surface, including your body. Most germs won’t harm you. Your immune system protects you against infectious agents.
What are the two types of bacteria?
There are broadly speaking two different types of cell wall in bacteria, that classify bacteria into Gram-positive bacteria and Gram-negative bacteria .
What is the primary route of disease transmission in a healthcare facility?
The primary routes of infectious disease transmission in U.S. healthcare settings are contact, droplet, and airborne . Contact transmission can be sub-divided into direct and indirect contact.
What are the principal routes of transmission of nosocomial infections?
Nosocomial infections, that develop as a result of a stay in hospital or are produced by micro-organisms and viruses acquired during hospitalisation may have several different transmission routes: contact, droplet, air, water, food, or disease vector carrying and transmitting an infectious pathogen, or blood .
How will you control infection in OT?
- Reusable scrub suits. Traditional, textile scrub suits are washed between surgeries and reused. ...
- Single-use polypropylene scrub suits. Single-use scrub suits are discarded after use, reducing the risk of infection. ...
- Clean air suits. ...
- Surgical drapes. ...
- Washing the skin.
What are the five main points that must be followed in standard precautions?
- Hand hygiene.
- Use of personal protective equipment (e.g., gloves, masks, eyewear).
- Respiratory hygiene / cough etiquette.
- Sharps safety (engineering and work practice controls).
- Safe injection practices (i.e., aseptic technique for parenteral medications).
- Sterile instruments and devices.
What are infectious diseases also known as?
Communicable diseases , also known as infectious diseases or transmissible diseases, are illnesses that result from the infection, presence and growth of pathogenic (capable of causing disease) biologic agents in an individual human or other animal host.
