What are the two kinds of transmission?
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.
Indirect contact transmission occurs when there is no direct human-to-human contact..
What are the three types of transmission based precautions?
There are three categories of Transmission-Based Precautions: Contact Precautions, Droplet Precautions, and Airborne Precautions.
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 is the mode of transmission of pneumonia?
Pneumonia can be spread in a number of ways. The viruses and bacteria that are commonly found in a child’s nose or throat, can infect the lungs if they are inhaled. They may also spread via air-borne droplets from a cough or sneeze.
Is TB spread by contact route?
M. tuberculosis is transmitted through the air, not by surface contact. Transmission occurs when a person inhales droplet nuclei containing M. tuberculosis, and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs (Figure 2.2).

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.
Which action can prevent or stop the spread of communicable diseases?
Washing hands properly is one of the most important and effective ways of stopping the spread of infections and illnesses. Wash your hands thoroughly using water and plain soap. Wash for at least 20 seconds and dry them completely. Using warm water is preferable, if available.

What is the most common mode of transmission?
Contact transmission. The most common mode of transmission, contact transmission is divided into two subgroups: direct contact and indirect contact.
What are the main routes infection can enter the body?
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 six modes of transmission for communicable diseases?
Infectious agents include helminths, protozoa, bacteria, viruses and fungi. Six factors are involved in the transmission of communicable diseases: the infectious agent, the reservoir, route of exit, mode of transmission, route of entry, and the susceptible host.

What are the 4 routes of 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 three types of transmission?
The 3 Types of Transmissions: Manual, Automatic, and CVT If you know anything about transmissions, you probably know that there are different types of transmission. You almost certainly will have heard about manual and automatic transmissions.
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. Figure 3.

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.
