What are two airborne diseases?

The CDC recommends that all people wear cloth face masks in public places where it’s difficult to maintain a 6-foot distance from others. … The common cold. … Influenza. … Chickenpox. … Mumps. … Measles. … Whooping cough (pertussis) … Tuberculosis (TB)More items…

How do infections enter the body?

Some infections are spread directly when skin or mucous membrane (the thin lining of parts of the body such as nose, mouth, genitals) comes into contact with the skin or mucous membrane of an infected person. Infections may be spread indirectly when the skin comes in contact with a contaminated object.

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).

Is TB airborne or droplet?

M. tuberculosis is carried in airborne particles, called droplet nuclei, of 1– 5 microns in diameter. Infectious droplet nuclei are generated when persons who have pulmonary or laryngeal TB disease cough, sneeze, shout, or sing. TB is spread from person to person through the air.

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.

Is airborne transmission direct or indirect?

With airborne transmission, direct contact is not needed to spread disease (as compared with respiratory droplet transmission). Infection may be transmitted over short distances by large droplets, and at longer distances by droplet nuclei generated by coughing and sneezing.

What are the five signs of an infection?

What are 4 types of isolation?

According to the CDC, the three standard categories of transmission-based precautions include contact isolation, droplet isolation, and airborne isolation.Standard Precautions. … Contact Isolation. … Droplet Isolation. … Airborne Isolation.Mar 10, 2020

Which disease can be transmitted through blood?

​Bloodborne pathogens are microorganisms such as viruses or bacteria that are carried in blood and can cause disease in people. There are many different bloodborne pathogens, including malaria, syphilis, and brucellosis, and most notably Hepatitis B (HBV), Hepatitis C (HCV) and the Human Immunodeficiency Virus (HIV).

What is indirect transmission?

Indirect transmission refers to the transfer of an infectious agent from a reservoir to a host by suspended air particles, inanimate objects (vehicles), or animate intermediaries (vectors).

What are the 5 methods of disease transmission?

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.

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.

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.More items…

What are examples of transmission-based precautions?

Transmission-based precautionsairborne 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.

Do airborne precautions require N95?

A particulate respirator must be worn by anyone entering the patient’s room that is on airborne precautions. This may be an N95 respirator or powered air purifying respirator or PAPR.

How are disease spread?

Person to person. 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 diseases can you get from indirect contact?

Infectious diseases are transmitted from person to person by direct or indirect contact. Certain types of viruses, bacteria, parasites, and fungi can all cause infectious disease….5. Animal reservoirsanthrax (from sheep)rabies (from rodents and other mammals)West Nile virus (from birds)plague (from rodents)

What are the three types of transmission based precautions?

Transmission-Based Precautions. There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.

What is the most common mode of indirect transmission?

Indirect contact infections spread when an infected person sneezes or coughs, sending infectious droplets into the air. If healthy people inhale the infectious droplets, or if the contaminated droplets land directly in their eyes, nose or mouth, they risk becoming ill.
