- Hands to food:
- Food to hands to food:
- Infected child to hands to other children:
- Animals to people:
What are the 6 links in the chain of infection?
The six links include: the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. The way to stop germs from spreading is by interrupting this chain at any link.
What are the 6 major types of pathogens?
There are six different types of pathogens. They include: bacteria, viruses, fungi, protozoans, helminths, and prions.
What are the 5 main ways that pathogens 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 portals of entry?
PORTAL OF ENTRY The opening where an infectious disease enters the host’s body such as mucus membranes, open wounds, or tubes inserted in body cavities like urinary catheters or feeding tubes.
How are pathogens transmitted?
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.
What are 5 pathogens?
Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms. Some common pathogens in each group are listed in the column on the right. Infectious agents can grow in various body compartments, as shown schematically in Fig.
What are the routes of entry for pathogens?
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.
How do pathogens enter the body BBC Bitesize?
This can be sexual contact during intercourse or non-sexual contact, like shaking hands. Dirty water can transmit many diseases, such as the cholera bacterium. When a person who is infected by the common cold sneezes, they can spray thousands of tiny droplets containing virus particles to infect others.
What are portals of entry into the body?
A portal of entry is the site through which micro-organisms enter the susceptible host and cause disease/infection. Infectious agents enter the body through various portals, including the mucous membranes, the skin, the respiratory and the gastrointestinal tracts.
How pathogens can be transmitted?
What are the different portals of entry for a pathogen to enter the body?
