What are 5 ways that pathogens spread?

5 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:

What are the 4 routes of transmission?

Routes of transmission

  • Direct Contact Transmission. Direct contact transmission occurs through direct body contact with the tissues or fluids of an infected individual.
  • Fomite Transmission.
  • Aerosol (Airborne) Transmission.
  • Oral (Ingestion) Transmission.
  • Vector-Borne Transmission.
  • Zoonotic Transmission.

Can pathogens be transmitted from one person to another through talking?

Droplets spread by sneezes, coughs, or simply talking can transmit infection if one person comes in contact with the mucous membranes of the eye(s), mouth, or nose of another person.

What are the 6 types of pathogens?

Infectious diseases are caused by pathogens, which include bacteria, fungi, protozoa, worms, viruses, and even infectious proteins called prions.

What diseases are spread through bodily fluids?

Examples of diseases spread through blood or other body fluids:

  • hepatitis B – blood, saliva, semen and vaginal fluids.
  • hepatitis C – blood.
  • human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.
  • cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.

What are the 8 modes of transmission?

Modes of transmission

  • Direct. Direct contact. Droplet spread.
  • Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)

What are the 6 modes of 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 main types of pathogens?

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

Which pathogens are spread by coughs and sneezes?

Coughs and sneezes create respiratory droplets of variable size that spread respiratory viral infections. Because these droplets are forcefully expelled, they are dispersed in the environment and can be inhaled by a susceptible host.

What are 3 bodily fluids that are infectious?

Potentially infectious blood and body fluids include

  • fluids containing visible blood.
  • semen.
  • vaginal secretions.
  • cerebrospinal fluid.
  • synovial fluid, pleural fluid.
  • peritoneal fluid.
  • pericardial fluid.
  • amniotic fluid.

What diseases are spread through direct contact?

Many illnesses spread through contact transmission. Examples are chicken pox, common cold, conjunctivitis (Pink Eye), Hepatitis A and B, herpes simplex (cold sores), influenza, measles, mononucleosis, Fifth disease, pertussis, adeno/rhino viruses, Neisseria meningitidis and mycoplasma pneumoniae.

What are the 3 major portals of entry for disease?

An anatomic site through which pathogens can pass into host tissue is called a portal of entry. These are locations where the host cells are in direct contact with the external environment. Major portals of entry are identified in Figure 3 and include the skin, mucous membranes, and parenteral routes.

What are four ways pathogens 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.

What are four ways diseases 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.

How can pathogens be transmitted?

Pathogens can be transmitted to humans through contact with animals, birds, and other living creatures that naturally harbor the microorganism. The agent of anthrax- Bacillus anthracis -naturally dwells in sheep.
