Respected sir,
With due respect, I would like to say that in our society there are little measures taken to prevent diseases as compared to the measures taken for curing of diseases. We shall realize that the curing of diseases will become a lot lesser if we apply effective strategies to prevent diseases. If just the water supply to our house-hold comes clean, then this preventive measure will stop different kinds diseases to occur which will not have to be cured then.

Hence, I will request you to kindly take measures on cleanliness and prevention of diseases in our society.
Thanks
