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.

small number of disease-causing bacteria and viruses
. Bacteria and viruses in the saliva or blood of one person can be spread to another person by kissing. Some diseases are more easily spread than others.
What are the 5 modes 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 major disease vectors?
Vector-borne diseases are illnesses that are transmitted by vectors, which include
mosquitoes, ticks, and fleas
. These vectors can carry infective pathogens such as viruses, bacteria , and protozoa , which can be transferred from one host (carrier) to another.
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 8 modes of transmission?
- Direct. Direct contact. Droplet spread.
- Indirect. Airborne. Vehicleborne. Vectorborne (mechanical or biologic)
What is the number one mode of transmission?
Contact
is the most frequent mode of transmission of health care associated infections and can be divided into: direct and indirect. An example of contact transmitted microorganisms is Noroviruses which are responsible for many gastrointestinal infections.
How does class 9 spread through water?
Disease can also be spread through water. This occurs if
the excreta from someone sufferingfrom an infectious gut gets mixed with water
. Eg cholera, gets mixed with the drinking waterused by people living near by. The cholera causing microbes will enter new hosts through thewater they drink and cause disease in them.
What is the mode of transmission of pneumonia Class 9?
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
.
What is direct transmission class 9?
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.
How does a girl feel after kissing?

Can humans be vectors of disease?
Many factors affect the incidence of vector-borne diseases. These factors include animals hosting the disease, vectors, and people.
Humans can also be vectors for some diseases
, such as Tobacco mosaic virus, physically transmitting the virus with their hands from plant to plant.
