so i'll be taking a 2 week trip to india. One night in Delhi, followed by 10 days in Leh, and then another full day in Delhi. i've never been to India before, but have traveled in the middle east and europe. What precautions should i take? i've heard some people take the malaria treatment preemptively, but i would like to avoid it if possible. obviously i will bring bug spray. but anything else i'm missing. the dates are 8/13-8/27
