I too got this fever last time when I was in India, it occured frequently and therefore I decided to go back to England as I spent most of my holidays in sickness and my plan was all scrwedup.
I was so frustated by the muncipalties and local healthcare carelessness even though thousands were reported to have infected but nothing was being done.
Always govt. starts taking measures when everything goes extreme, why can't tackle it when at the begining stage?
