In medical news, President Bush is warning that the country could face another avian flu epidemic and that the military might be needed to enforce quarantines and other emergency measures. He discussed this during Tuesday’s press conference. Health and Human Services Secretary Mike Leavitt has said preparing for such an outbreak is the most important health preparedness issue facing the country. The last such outbreak was in 1968. The deadliest occurred in 1918 when as many as 50 million people died around the world including over 600,000 in the United States. Meanwhile scientists have just announced they have reconstructed the 1918 Spanish flu virus and found that it was a bird flu that jumped directly to humans.
