One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than100,000 people. It's swine flu that has made life in Mexico City grind to a halt .

Governments are trying to find ways to prevent further out-breaks. The World Health Organization has raised its swine flu global threat level to five out of six.

Humans can also catch swine flu. The virus causes regular outbreaks in pigs, but people usually do not catch it.

The high proportion of young adults among the deaths is one of several mysteries about this virus. Most of the dead had lung damage. What caused it is not yet known. The virus spreads the same way the common flu does. When an infected person coughs or sneezes around another person, the latter is put at risk. People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes. There are medicines to treat swine flu. Doctors suggest using anti - viral drugs. They keep the virus from reproducing inside the body. Although there are no vaccines for it now, several everyday steps can help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it.
