The World Health Organization (WHO) advised yesterday travelers to forested areas in Brazil to get yellow fever vaccinations as the number of confirmed deaths from the disease in the country climbed to five. The WHO warning is valid for the forested areas of inland Brazil that cover about three-quarters of the country, but which are well away from the tourist hotspots of Rio de Janeiro and other coastal destinations.
