The predictable pandemic

摘要

The swine flu virus has been a serious pandemic threat for years, New Scientist can reveal - but research into its potential has been neglected compared with other kinds of flu.rnAs New Scientist went to press, cases were being reported far from the original outbreak in Mexico. The clusters of milder infections in the US suggest the virus is spreading readily among people. The US Centers for Disease Control and Prevention (CDC) says this strain is so different from existing human flu viruses that most people have no immunity to it. There are no existing vaccines.
