I think I already told you that I was poked a prodded before coming to India with a handful of drugs and vaccines. The only major concern was malaria, since there is no vaccine. The best cure is a preventative of not being bitten by any mosquitos - unfortunately it has the nasty side effect of causing slasher nightmares.
I was expecting mosquito netting in our hotel rooms, but we really don't have open windows in Delhi and Jaipur. In Ranthambhore, however, we did have some water drainage problems in our bathroom, and we saw a mosquito in our bathroom.
Yikes.
