Transmission is the process by which pathogens spread from one place to another. Diseases or infections are often contagious. It can be transmitted directly from person to person, some bacteria, viruses, protozoa or fungi. There are two different modes of transmission:
Disease Transmission
When an infected person comes into contact with or exchanges body fluids with an uninfected person. The mother can transmit the infection to the fetus through the placenta. Sexually transmitted diseases such as syphilis can be transmitted through direct communication.
Droplets are spread by coughing, talking and sneezing of an infected person can spread the disease. Infections can also be spread by touching the nose and mouth with hands containing infectious droplets. The droplets are so fine that they only travel a short distance before falling. People in this area can be infected.
There are several infections such as chicken pox, conjunctivitis, lice, tapeworms, etc. that are spread through skin-to-skin contact with another infected person.
Some diseases are spread when the body fluids or blood of an infected person come into contact with the skin or blood of an uninfected person. Diseases such as hepatitis, HIV, and cytomegalovirus infection are spread through semen and vaginal fluid, saliva, breast milk, and urine.
Indirect Transmission
Some coatings remain suspended in the air for extended periods of time. The bacteria can attack the immune system of the person in contact. For example. If you enter a room that was originally occupied by a measles patient, you can also catch the infection.
Our surroundings carry pathogens. To begin with, touching contaminated materials used by patients can make us sick. Contaminated blood and medical equipment can spread the disease.
Some infectious agents are transmitted by blood-sucking insects. Insects eat birds, animals, humans and other insects and carry insects from them. These infections are transmitted to any new family. Measles and Lyme disease are two infectious diseases.
