As others have noted, the chances of contracting Ebola in India are so close to zero that they are literally not worth worrying about. Even closer to zero if you practice hygiene precautions at a paranoid level already, as you suggest that you do.
There are worse places to be overall-health-wise than India, I suspect.
I've visited LA, New Delhi and Chennai, amongst 'quite a few' other places. The chances of dying from gunshot or car accident or being mugged or having my lungs (slightly more) eroded by air pollution in LA would make any dangers I faced in Chennai or ND more attractive. I'd love to spend more time looking around LA, but given the choice if I was offered a free one week trip to any of the 3, LA would be last on my list. [I'd probably choose ND and take a quick trip to Nepal].
FWIW people 'under watch' for Ebola have a finite or low chance of actually having it. In China I met a young couple who were unwise enough to try to cross Vietnam-China at a less common border crossing during one of the bird flu scares. He had been carrying her pack and it was a hot day and ... . Would you come with me, please, Sir, or equivalent. Some weeks were served in a Vietnamese hell-hole (didn't have to be that way, it's just what the authorities decided to do) with some very illogical actions along the way before being sent on their way. How is that relevant to you? In this way ....
When you rush to the departure gate all hot and bothered on a hot Indian day, take a moment to calm down, walk slower and wipe your brow with an alcohol wipe as you approach the IR scanner - or you may be closer to people "under watch" than you are at all happy with.
Note: What do you do for a living? If electrical/electronic or about anything "technical" (I learn real fast :-)), then if you ever want somebody to attend a conference in India on your behalf, all expenses paid and a modest per diem, please advise. Any time :-)
