Sian Griffiths, director of Hong Kong’s School of Public Health at the Chinese University, believes that the best method for stopping the spread of a bird flu pandemic is actually quite simple: good hygiene. Careful washing of hands and avoiding touching eyes, mouth or nose may significantly reduce the potential spread of influenza of any sort. Additionally, avoid close contact with those who are already sick or showing symptoms. Covering the mouth and nose with tissue when coughing or sneezing will also help limit the spread. Clean your hands.
