Newspaper headlines in Mexico City capture the fear and concern about a deadly outbreak of swine flu.

The head of the World Health Organization says the new strain has pandemic potential as it's killed mostly healthy young adults and the agency had declared a public health emergency of international concern.
Margaret Chan with the World Health Organization said, "I think that at this point in time, it is very important that all regions of the World Health Organization work with our countries to heighten surveillance."
The virus has killed as many as 68 people and sickened more than a thousand in Mexico.
Ten people in Texas , California and Kansas have also been diagnosed and New York city Health Officials have identified a potential outbreak at a Queens High School after testing samples taken from nine students.
New York City Health Commissioner Dr. Thomas R. Frieden said, “That Laboratory has identified those specimens, 8 out of 9 of those specimens as probable human swine influenza.”
