- General ways of preventing infection are:
Public hygiene is one basic key to the prevention of infectious disease. In the method of prevention of diseases, following practices are adopted:
- To avoid exposure to air-borne microbes, adopt living conditions that are not overcrowded.
- To prevent exposure to water-borne microbes, safe drinking water should be provided.
- To avoid vector-borne infections, we can provide clean environment as it would not allow mosquito breeding.
- Specific way of preventing infections:
The specific ways relate to a peculiar property of the immune system that usually fights off microbial infections. During smallpox epidemics, it was noted that people who survived after suffering from smallpox, did not get infected with it again. Such observations led to the birth of immunization, which is a specific method of preventing infectious diseases.
When the immune system first sees an infectious microbe, it responds against it and then remembers it specifically. So the next time that particular microbe, or its close relatives enter the body, the immune system responds with even greater vigour. This eliminates the infection even more quickly than the first time around. This is the basis of the principle of immunization.
Vaccines work on the principle of immunization. Vaccines help a body's immune system prepare in advance to fight infectious illnesses and potentially deadly diseases caused by infectious agents or their by-products. Vaccines ‘fool’ the immune system into developing a memory for a particular infection by putting something that mimics the microbe we want to vaccinate against, into the body. Many such vaccines are now available for preventing a number of infectious diseases, and provide a disease-specific means of prevention like tetanus, diphtheria, whooping cough, measles and polio.
