Explain various modes of transimission of infectious diseases.
Infectious diseases spread from one infected person to other normal person by various methodes.
(a) Air borne disease-For example: common cold, pneumonia and tuberculosis. such disease causing microbes are spread throughout the air. The transmission of these microbes occurs
through the little droplets coughed out by an infected person who sneezes or coughs. A person in the vicinity of such a person an inhale these disease causing microbes and may become infected.
(b) Water - borne diseases - For example: Cholera, infectious diseases can aos spread through water. These ocur when a stool from someone suffering from an infectious gut disease such as cholera or amoebiasis, gets mixed with the dringking water used by people living nearby. The cholera infested bacterial can enter new hosts throug the water they drink and can cause disease in them.
(c) Sexually transmitted diseases - For example; symphils and AIDS. Both of these pathogens are transimtted by sexual contact from one partner to the other. However, such sexually transmitted diseases are not spread by casual physical contact.
(e) Formite borne diseases - Articles coming in contact with the patients act as sources of infectio for example : door handles, taps, garments, utensils, crockery, etc.
(f) spread of disease through vectros- Many animal which live with us may carry diseases. These animals can transfer infecting agents from a sick person to another potential host. Thus, these animals act as intermediaries or vectors. For example - female anopheles mosquitos are vectors of disease, malaria.
