blood or other body fluids..

What are the 4 main routes for infection to 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.

How are infections transmitted?

Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.

What is the first thing you need to know about infection control?

The first step in infection control is hand hygiene.

What are the 6 modes of transmission?

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

How quickly can germs spread?

Researchers at the University of Bristol assessed the airborne survival of bacteria in aerosol droplets from coughs and sneezes. They found the average sneeze or cough can send around 100,000 contagious germs into the air at speeds up to 100 miles per hour.

What diseases are carried in body 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.More items…

Can a bacteria be cured?

Many human illnesses are caused by infection with either bacteria or viruses. Most bacterial diseases can be treated with antibiotics, although antibiotic-resistant strains are starting to emerge. Viruses pose a challenge to the body’s immune system because they hide inside cells.

How do viruses enter the human body?

In humans, viruses that cause disease like cold and flu are spread through bodily fluids, like spit or snot. The virus is so small that it leaves our bodies in these fluids, and can even float through the air in droplets from a sneeze or cough. The virus can enter the body through the eyes, nose, or mouth.

What are the 3 main ways infection can get into the body?

This is the way that the pathogen enters the body of the potential host. Pathogens can enter the body by coming into contact with broken skin, being breathed in or eaten, coming into contact with the eyes, nose and mouth or, for example when needles or catheters are inserted.

What are the five basic principles for infection control?

These include standard precautions (hand hygiene, PPE, injection safety, environmental cleaning, and respiratory hygiene/cough etiquette) and transmission-based precautions (contact, droplet, and airborne).

What is the main route to spread infection dust?

Airbone transmission of infectious agents occurs either by: Airborne droplet nuclei (small particles of 5 mm or smaller in size) • Dust particles containing infectious agents. Microoganisms carried in this manner remain suspended in the air for long periods of time and can be dispersed widely by air currents.

What are the basic infection control?

What is the most effective way to prevent infection?

Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for pathogens like viruses and bacteria) casually by touching another person.

How are diseases spread through air?

You can catch some diseases simply by breathing. These are called airborne diseases. Airborne disease can spread when people with certain infections cough, sneeze, or talk, spewing nasal and throat secretions into the air. Some viruses or bacteria take flight and hang in the air or land on other people or surfaces.

What are the 5 ways infectious diseases are transmitted?

What are the modes of infection?

Modes of transmissionDirect. Direct contact. Droplet spread.Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)

How do diseases spread through water?

Waterborne illness is caused by recreational or drinking water contaminated by disease-causing microbes or pathogens. Of note, many waterborne pathogens can also be acquired by consuming contaminated food or beverages, from contact with animals or their environment, or through person-to-person spread.
