CBSE - IX - Biology - Why Do We Fall Ill?
what is the difference between pesonal and community health? what are acquired and congenital diseases? how we can justify that'prevention is better than cure'?what are the causes,effects,pathogens,symptoms of typhoid,cholera,diarrhoea,anthrax,dengue,kala azar and malaria?
There are three limitations of this approach to dealing with infectious disease. These are:
- Once someone has a disease, their body functions are damaged and may never recover completely.
- Treatment will take time, which means that someone suffering from a disease is likely to be bedridden for some time even if we can give proper treatment.
- The person suffering from an infectious disease can serve as the source from where the infection may spread to other people. This leads to the multiplication of the above difficulties.
It is because of such reasons that prevention of diseases is better than their cure.
