"Maintenance of personal and public hygiene is necessary for the prevention and control of many infectious diseases." Justify the statement giving suitable examples.

(N/A) Personal hygiene measures include keeping the body clean, and the consumption of clean drinking water, food, vegetables, and fruits.
Public hygiene includes the proper disposal of waste and excreta, periodic cleaning and disinfection of water reservoirs, pools, cesspools, and tanks, and observing standard practices of hygiene in public catering.
These measures are particularly essential where infectious agents are transmitted through food and water, such as in cases of $Typhoid$, $Amoebiasis$, and $Ascariasis$.
Additionally, maintaining healthy habits such as regular exercise and adequate sleep strengthens the immune system, further aiding in disease prevention.
