General Ways
Hygienic conditions should be maintained in the surroundings we live in. There should be limited exposure to airborne microbes by providing not so crowded living conditions.
Safe drinking water should be provided to prevent water-borne diseases.
Provide a clean environment which prevents the breeding of mosquitoes. This prevents the spread of vector-borne diseases.
Specific Ways
The immune system normally fights off microbes. The cells of the immune system are specialized in killing infectious microbes. That is why we don’t always fall sick on coming in contact with an infectious person. As soon as an antigen enters the body, these cells come into play.
Immunization
It is the process by which a person is made resistant to a particular disease by the administration of a vaccine. A vaccine stimulates the immune system of a body to prevent certain diseases. This process has proved beneficial in preventing several infectious diseases and has decreased the mortality rate to a great extent. There are vaccines against tetanus, smallpox, measles etc. There are public health programmes for childhood immunizations to prevent any infections throughout our lives.
For effective prevention of diseases, everyone should practice public hygiene and immunization.
