  • Hands to food:
  • Food to hands to food:
  • Infected child to hands to other children:
  • Animals to people:

What are the 6 modes ways that pathogens can be transmitted?

The modes (means) of transmission are: Contact (direct and/or indirect), Droplet, Airborne, Vector and Common Vehicle.

How do pathogens work?

Pathogens cause illness to their hosts through a variety of ways. The most obvious means is through direct damage of tissues or cells during replication, generally through the production of toxins, which allows the pathogen to reach new tissues or exit the cells inside which it replicated.

What are the 6 types of pathogens?

Different types of pathogens

  • Bacteria. Bacteria are microscopic pathogens that reproduce rapidly after entering the body.
  • Viruses. Smaller than bacteria, a virus invades a host cell.
  • Fungi. There are thousands of species of fungi, some of which cause disease in humans.
  • Protists.
  • Parasitic worms.

What diseases can be transmitted through saliva?

Here are a few other illnesses which can work their way from your saliva into your nose, throat and lungs:

  • Rhinovirus (colds)
  • Flu virus.
  • Epstein-Barr virus (mononucleosis, or mono)
  • Type 1 herpes (cold sores)
  • Strep bacteria.

You cannot get TB germs from: Smoking or sharing cigarettes with others. Saliva shared from kissing. TB is NOT spread through shaking someone’s hand, sharing food, touching bed linens or toilet seats, or sharing toothbrushes.

How do 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 are the 5 main types of pathogens?

Pathogenic organisms are of five main types: viruses, bacteria, fungi, protozoa, and worms.

What are five ways in which pathogens are spread?

How Do Pathogens Spread? Droplet Infection: When you sneeze, cough or talk, you release tiny droplets in the air. Direct Contact: You may transfer your infection to someone else through direct contact of the skin. Contaminated Food and Water: Some pathogens can survive in foods and water, such as undercooked food and contaminated drinking water.

How are pathogens spread from one person to another?

Airborne transmission. Some infectious agents can travel long distances and remain suspended in the air for an extended period of time.

  • Contaminated objects. Some organisms can live on objects for a short time.
  • Food and drinking water.
  • Animal-to-person contact.
  • Animal reservoirs.
  • How does a pathogen spread through the body?

    Through Body Fluids: Pathogen can infect you by entering your body through semen and blood. Some of the most common examples of pathogens that spread through body fluids are hepatitis and HIV viruses.

    How can pathogens be transmitted to humans?

    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 . There are different types of pathogens, but we’re going to focus on the four most common types: viruses, bacteria, fungi, and parasites.
