Malaria is everywhere except North America, Europe and maybe Australia, New Zealand and Japan. Africa has Malaria below the Sahara except Addis Ababa (apparently mosquito's have a hard time getting up to the altitude this city is at).
A couple of years back in Uganda there was this radio station and if you were the 10th caller in some quiz you won: no, not a thousand dollars, euro's, local currency, no, grand prize was a mosquito net! Part of the fight malaria campaign.
If you're afraid of malaria don't go to India either. You'll have a choice actually: dengue fever or malaria. Take your pick. When you go to a hotel there beware of plug-in airfreshners. It are really some very potent mosquito killers and make you after a few hours very sick. How I know? Lets just say that the airport in Chennai smells worse than the one in Lagos. So you get to your room and see what looks like an airfreshner next to the tv. You plug it in in the hope that the room will smell nice and fresh when you wake up. However, a few hours later you'll wake up with a crashing headache and nauseated. Now the only solution you have is to open the windows, let the smelly air back in your room and if it's hot enough the mosquito's stay away. If the sun is not way above the horizon put on mosquito repellant before opening the aircraft door. It won't be one mosquito waiting for some fresh meat, it will be thousands.
