What are the common methods of transmission of diseases Class 9?
Disease TransmissionPerson to Person.
When an infected person comes in contact with or exchanges body fluids with a non-infected person.
Spread by skin.
Spread through body fluids or blood.

What are the three types of transmission based precautions?
There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.
What is a route of transmission?
The pathway of causative agents from a source to infection of a susceptible host is called ‘transmission route’. The characteristic of the transmission route depends mainly on the characteristics of the causative agent and those of the host.
What is the most common route 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.
Which are the correct route 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 is the common mode of transmission for these diseases?
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 main ways that pathogens can spread?
Five common ways germs are spread:Nose, mouth, or eyes to hands to others: Germs can spread to the hands by sneezing, coughing, or rubbing the eyes and then can be transferred to other family members or friends. … Hands to food: … Food to hands to food: … Infected child to hands to other children: … Animals to people:
How do infections enter the body?
Some infections are spread directly when skin or mucous membrane (the thin lining of parts of the body such as nose, mouth, genitals) comes into contact with the skin or mucous membrane of an infected person. Infections may be spread indirectly when the skin comes in contact with a contaminated object.
What is F diagram?
The F-Diagram is one of the many tools in the Participatory Hygiene and Transformation (PHAST) methodology which seeks to vividly describe in detail the fecal oral transmission route. It is a cycle characterized by F’s as follows: Fluids-the drinking of contaminated water. … Fingers-faecal contamination of fingers/hands.
What is disease transmission?
In medicine, public health, and biology, transmission is the passing of a pathogen causing communicable disease from an infected host individual or group to a particular individual or group, regardless of whether the other individual was previously infected.
What are the four ways pathogens can enter the body?
Pathogens can be transmitted a few ways depending on the type. They can be spread through skin contact, bodily fluids, airborne particles, contact with feces, and touching a surface touched by an infected person.
Where do most pathogens 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 do all germs have in common?
Different germs have favorite places they like to live, different ways to spread and their own unique ways of causing infections. And all germs have one thing in common: When they find a place that is good for them to live, they set up a home for themselves and multiply.
How do viruses enter the body?
Usually these microorganisms enter the body through the mouth, eyes, nose, genitals or through wounds, bites or any open wounds. Moreover, they are transmitted through different routes. Some diseases are spread by direct contact with infected skin, mucous membranes or body fluids.
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 can break the chain of infection?
No matter the germ, there are 6 points at which the chain can be broken and a germ can be stopped from infecting others. The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host.
What disease is associated with bacteria?
Bacteria cause many common infections such as pneumonia, wound infections, bloodstream infections (sepsis) and sexually transmitted diseases like gonorrhea, and have also been responsible for several major disease epidemics.
What is the most effective way to prevent infection?
Simply put, yes. Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for microbes like viruses and bacteria) casually by touching another person.
Do germs jump?
Summary: Bacteria may be able to jump between host species far easier than was previously thought, a new study suggests. Researchers discovered that a single genetic mutation in a strain of bacteria infectious to humans enables it jump species to also become infectious to rabbits.
What are the 7 pathogens?
Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions.
