International experts are in Nigeria to advise authorities on what preventive measures they should be taking, including closing live-poultry markets and restricting poultry movements. "Above all it is an animal disease and if one wants to avoid there being any human cases, the virus must really be stamped out in the bird population," World Health Organisation spokeswoman Fadela Chaib told reporters in Geneva. No human cases have been found in Nigeria, the first African country to confirm cases of H5N1, and health officials said on Tuesday that two children suspected of having the virus probably did not have it after all. Greece also said tests on a man suspected of having bird flu had come back negative. Although the European Union has not reported any human infections or deaths directly from the virus, the pressure of its arrival has taken its toll on some people. After losing his job because of falling poultry sales, an Italian trucker murdered his wife and child before committing suicide, local newspapers reported.
