I am going to Delhi and various towns in Rajasthan this summer. This part of India is usually low risk but then again, it will be monsoon season. I've been to see my GP who says it's a none to low risk area. Any idea if Proguanil and Chloroquine is advisable for this area? I am only going for 3 weeks. Is it worth taking medication?
True, July/August is typically monsoon season in India. But then, large parts of Rajasthan - and most of the major tourist regions, which are in the northwest parts of Rajasthan - lie in a region of rain shadow due to the Aravalli mountain range.
To get a general idea of what the rainfall in different regions is, this text from the Rajasthan government site is useful. (Use it to look up the areas you're going to.)
Those figures are per month and fairly low by most standards. So by my most practical standards, you certainly don't need malaria medication. Look at answers for 'Do I need malaria medication for Rajasthan in February?' - practically the same advice applies. If it reduces your anxiety, by all means go ahead though. Also of interest to you would be 'Can I buy malaria medication in India?'
