What are the 4 types of disease 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 modes of disease transmission?
Modes of transmission
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What is an agent that can cause infections and diseases?
The agents that cause disease fall into five groups: viruses, bacteria, fungi, protozoa, and helminths (worms). Protozoa and worms are usually grouped together as parasites, and are the subject of the discipline of parasitology, whereas viruses, bacteria, and fungi are the subject of microbiology.
What are the common methods of transmission of diseases?
Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.
What are the common methods of transmission of diseases Class 9?
- Person to Person. When an infected person comes in contact with or exchanges body fluids with a non-infected person.
- Droplet Transmission.
- Spread by skin.
- Spread through body fluids or blood.
- Airborne Transmission.
- Contaminated Objects.
- Vector-Borne Diseases.
- 4.Food and Drinking Water.
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 are examples of transmission-based precautions?
- airborne transmission, e.g., pulmonary tuberculosis, chickenpox, measles.
- droplet transmission, e.g., influenza, pertussis (whooping cough), rubella.
- contact transmission (direct or indirect), e.g., viral gastroenteritis, Clostridium difficile, MRSA, scabies.
What is the contact precaution?
Contact precautions are used when a person has a type of bacteria or virus on the skin or in a sore, or elsewhere in the body, such as the intestine, that can be transmitted to someone else if that person touches the infected individual or contaminated surfaces or equipment near the infected individual.

In addition to Standard Precautions, use Contact Precautions in the care of patients known or suspected to have a serious illness easily transmitted by direct patient contact or by indirect contact with items in the patient’s environment.
Is E coli contact precaution?
In long-term care facilities, residents with pathogenic E. coli should be placed on Contact Precautions until their symptoms subside.
What is direct contact?
Direct contact includes touching an infected individual, kissing, sexual contact, contact with oral secretions, or contact with body lesions. This type of transmission requires close contact with an infected individual, and will usually occur between members of the same household or close friends and family.
How can direct contact transmission be prevented?
How to prevent disease transmission
- wash your hands or use hand sanitizer before handling food and after shaking hands.
- always wash with soap and water if your hands are visibly soiled.
- try to minimize touching your mouth or nose with your hands.
- avoid sick people, if possible.
What is indirect contact mean?

What are the four main causes of infection?
Infectious diseases can be caused by:
- Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis.
- Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS.
What is the biggest source of infection spread to others?
Infectious diseases are caused by organisms (germs) such as bacteria, viruses, fungi or parasites….Germs can spread from person to person through:
- the air as droplets or aerosol particles.
- faecal-oral spread.
- blood or other body fluids.
- skin or mucous membrane contact.
- sexual contact.
What is the only body part that Cannot repair itself?
What happens if a bacterial infection goes untreated?
An untreated bacterial infection can also put you at risk for developing a life-threatening condition called sepsis. Sepsis occurs when an infection causes an extreme reaction in your body. The bacteria most likely to cause sepsis include Staphylococcus aureus, E. coli, and some types of Streptococcus.
How long does it take for a bacterial infection to go away with antibiotics?
“Antibiotics will typically show improvement in patients with bacterial infections within one to three days,” says Kaveh.
