WHO has an interesting website which will be very helpful for international travellers with basic data to decide and prepare for a happy & healthy touring across the globe. The site tells you key information such as Country profile overview , basic statistics on population / health spends cover / gdp / life expectancy / mortality rates / Outbreaks and crisis / health service coverage / risk factor / health systems. Interested people may visit www.who.int/countries for further details. As with most of the websites, the data seems few years older but still lot more relevant and useful.
