Name 4 ways that different types of disease can interact to make a person ill.

Answers

Answer:

Modes of transmission or means of transmission  is defined as the movement or transmission of pathogen from infected person or any reservoir to other person.

4 ways or modes of transmission of diseases include:

Contact (direct and/or indirect) -  Direct contact include physical relation between infected person or susceptible person such as kissing, sexual contact or transfer of oral secretion. Diseases caused by direct contact include small pox, pink eye and hepatitis a and B. Indirect contact include transmission of diseases form infected    person to susceptible person through a infected surface such as infected needle.Droplet: water droplet coming out of the mouth, perspiration or other open parts of the body carries pathogens to susceptible person. sneezing and coughing are most common of droplet ways through which diseases spread.Airborne: Some of the diseases are spread through means of air such as  chickenpox virus,  norovirus, measles morbillivirus, Mycobacterium tuberculosis and influenza virus et-cetra.Vector: Vectors are defined as an organism that carries disease causing pathogens from infected person to other host body. Fleas or other insects are example of vectors.

Hence, 4 ways that different types of disease transmission that can make a person ill are droplet, Contact (direct and/or indirect), vectors and airborne.
