Transmission is the process by which disease-causing microorganisms (pathogens) spread from one individual to another. Diseases or infections can be transmitted in many ways, it can be directly transmitted from one person to another, or with the help of a carrier.
There are two modes of transmission of diseases:
1. Direct Transmission - The pathogen is transmitted from an infected person to a healthy person. For example, if an open wound of a healthy person comes in contact with the blood of a Hepatitis B infected patient, the wounded person might contract the disease.Various modes of disease transmission are as follows:Droplet Transmission - Tuberculosis
Spread by skin - Ringworm infection
Spread through body fluids - Chicken Pox
2. Indirect Transmission - The pathogens are transmitted from an infected person to a healthy person through vectors such as flies, mosquitoes, dogs, etc.,
