Answer 1

Answer: (A), (C)

Maintaining public hygiene

$\bullet$ Infectious diseases can be prevented by maintaining public health, hygiene and immunisation.

$\bullet$ Proper functioning of our immune system is necessary to fight off pathogens and prevent them from causing any kind of infection. Intake of safe drinking water and food in proper amounts can prevent our body from getting infected.

$\bullet$ Collecting and cleaning of garbage cans on the street regularly helps prevent the spread of diseases, as waste and decaying matter provide nutrients for pathogens. Accumulation of waste and stagnation of dirty water leads to the breeding of vectors. Hence, public hygiene is crucial for individuals health.

$\bullet$ Immunisation is the process where a person is made resistant to an infectious disease. This is done by the administration of a vaccine. These vaccines stimulate body’s own immune system to protect the person against future infection or disease.
