What are the methods of disease control?
The infectious diseases may be prevented in one of two general ways: (1) by preventing contact, and therefore transmission of infection, between the susceptible host and the source of infection and (2) by rendering the host unsusceptible, either by selective breeding or by induction of an effective artificial immunity..
What are the 6 modes of transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the main routes that infection can enter the body?
Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.
What are the four types of disease 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 5 modes of disease transmission?
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 are the three major components of the cycle of transmission?
It is a process that begins when (1) an infectious agent or pathogen (2) leaves its reservoir, source, or host through (3) a portal of exit, (4) is conveyed by some mode of transmission, (5) enters the host through an appropriate portal of entry, and (6) infects a susceptible host.
What is vehicle transmission of infection?
Common vehicle transmission: Common vehicle transmission refers to transmission through a contaminated source. Examples include food, medication, intravenous fluid, or equipment that transmits infection to multiple hosts. This transmission may result in a large-scale outbreak. b.
What are the 3 major portals of entry for disease?
Portals of entry into the human body include:Inhalation (via the respiratory tract)Absorption (via mucous membranes such as the eyes)Ingestion (via the gastrointestinal tract)Inoculation (as the result of an inoculation injury)Introduction (via the insertion of medical devices)
What are the four basic rules of standard precautions?
Standard PrecautionsHand 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.More items…
What is data transmission and its types?
There are two methods used to transmit data between digital devices: serial transmission and parallel transmission. Serial data transmission sends data bits one after another over a single channel. Parallel data transmission sends multiple data bits at the same time over multiple channels.
How many types of disease transmission modes are there?
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 are the methods of transmission?
Transmission can be by direct or indirect contact or through airborne transmission. Direct contact is person-to-person transmission of pathogens through touching, biting, kissing, or sexual intercourse. Microorganisms can also be expelled from the body by coughing, sneezing or talking.
What are the 4 major disease vectors?
Disease vectorsMalaria (protozoan): Anopheles species of mosquito.Lymphatic filariasis (nematode worm): Culex, Anopheles, Aedes species of mosquito.Dengue (virus): Aedes species of mosquito.Leishmaniasis (protozoan): mainly Phlebotomus species of sandfly.More items…
