This obvious link between IQ and health outcomes does not get mentioned in the Washington Post story:
The island nation of Madagascar and the landlocked Himalayan nation of Bhutan might seem like charming tourist attractions. Travelers might want to think twice before visiting them, though. A recent Health Risk index by International SOS urges caution for visitors to those two countries, among other places.
The world map reprinted here is a reflection of more than 300,000 medical incidents which were reported in 2014 by companies to International SOS, which specializes in health care and emergency services to clients with business travelers overseas. Based on that data, a panel took into account threats of infectious disease, hygiene and sanitation, frequency of accidents and the availability and quality of the local health infrastructure to determine how risky a trip to a particular country might be.
Despite their pristine natural beauty, Bhutan and Madagascar pose an array of risks: from the difficulty of finding adequate hospitals in remote areas to poor sanitation in others.
Some classifications made in this index ought to be questioned, though. Cuba, for instance — a country whose doctors are internationally renowned — was classified as a “high risk” country in the Americas.
