I came upon this map yesterday, which shows outbreaks, cases and deaths from various viruses and bacterial diseases. It seems now that Dengue Fever is the most prevalent, mainly in India and SE Asia. It also reports suspicious "powders" and lock downs associated with same. A good information source, especially if you plan to travel.
