A woman with symptoms of dengue fever gets an IV solution at a Brazilian Air Force (FAB) field hospital set up in Rio de Janeiro, Brazil, April 2, 2008. The FAB is operating 3 field hospitals in Rio de Janeiro to help contain an outbreak of dengue fever in which at least 67 people have died this year alone. Dengue, spread by mosquitoes, is normal in Rio, but an apparent neglect of prevention measures has let is get out of control this year. (Australfoto/Douglas Engle)
