What are the common methods of transmission of diseases?
Infectious diseases are transmitted from person to person by direct or indirect contact….Indirect contactAirborne transmission.
Food and drinking water.
Insect bites (vector-borne disease)More items….
How do vectors transmit diseases?
Vector-borne diseases are infections transmitted by the bite of infected arthropod species, such as mosquitoes, ticks, triatomine bugs, sandflies, and blackflies. Arthropod vectors are cold-blooded (ectothermic) and thus especially sensitive to climatic factors.
What are the 6 modes of transmission?
Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What are the three types of transmission based precautions?
There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.
Are any viruses airborne?
Airborne diseases are illnesses spread by tiny pathogens in the air. These can be bacteria, fungi, or viruses, but they are all transmitted through airborne contact. In most cases, an airborne disease is contracted when someone breathes in infected air.
What is the difference between a reservoir and a vector?
A disease reservoir is analogous to a water reservoir. But instead of supplying water, a disease reservoir serves as a supply for a virus or other pathogen. Vector: Any living creature that can pass an infection to another living creature.
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 the mode of transmission of tuberculosis?
tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. TB is spread from person to person through the air.
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 are the four routes of 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 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…
What are 5 ways infectious diseases can be spread?
Infectious diseases can spread in a variety of ways: through the air, from direct or indirect contact with another person, soiled objects, skin or mucous membrane, saliva, urine, blood and body secretions, through sexual contact, and through contaminated food and water.
What is the difference between communicable and contagious?
A communicable disease is a contagious one. The effect is external. If someone catches the illness, they can get sick and spread the pathogen—be it a cold, virus, or some other disease-causing agent—onto the next person. This can lead to small, isolated outbreaks or full-scale pandemics.
How can droplet transmission be prevented?
To prevent or reduce droplet transmission, cough or sneeze into a tissue or your elbow. Then, wash your hands so you don’t pass your germs on.
What is the number one mode of transmission?
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 is an example of airborne transmission?
Diseases capable of airborne transmission include: Tuberculosis. Chickenpox. Measles.
How are disease spread?
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.
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 is vehicle transmission of infection?
The term vehicle transmission refers to the transmission of pathogens through vehicles such as water, food, and air. Water contamination through poor sanitation methods leads to waterborne transmission of disease. Waterborne disease remains a serious problem in many regions throughout the world.
What is the definition of mode of transmission?
The mode (means) of transmission is the route or method of transfer by which the infectious microorganism moves or is carried from one place to another to reach the new host. The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle. Portal of Entry.
What is an example of disease transmission?
Examples of direct contact are touching, kissing, sexual contact, contact with oral secretions, or contact with body lesions. Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air.
