The mother of Louiza Nevish Bati, 23, who died of the Marburg virus in Uige, Angola, collapses on her grave. A cousin of Ebola, the Marburg virus is highly contagious, making any outbreak a cause for widespread fear and fascination in a world shrunk by international travel and trade. Marburg spreads through blood, vomit, semen and other bodily fluids. Even a cough can prove fatal for someone hit by a few drops of spittle. Corpses, teeming with the virus, are especially dangerous. A contaminated surface can be deadly -- the virus can find its way into someone's eyes, nose or mouth, or enter the bloodstream through a cut.
