Swine Flu Case in the US
According to the USA Today, news of the spread of a novel, possibly life-threatening, swine flu strain escalated over the weekend, not only in Mexico but the United States as well.
There were 20 confirmed cases in five states, school closings in some areas, and the drain of the government's stockpile of antivirals drugs to combat the virus.
"We have an outbreak of new infectious disease that we are approaching very aggressively," said Richard Besser, the acting director of the Centers for Disease Control and Prevention at a White House news conference.
The New York Times reported that American health officials declared a public health emergency on Sunday as 20 cases of swine flu were confirmed in this country, including eight in New York City.
Other nations had imposed travel bans or made plans to quarantine air travelers as confirmed cases had also shown up in Mexico and Canada and suspect cases emerged elsewhere.
Top global flu experts struggled to predict how dangerous the new A (H1 N1) swine flue strain would be as it became evident that not enough information is known about Mexico's outbreak.
"We're in a period in which the picture is evolving," said Dr. Keiji Fukuda, deputy director general of the World Health Organization.
Swine flu causes flulike symptoms including respiratory congestion, fever and achy joints, but it mimics many other respiratory infections, said Anne Shuchat, interim deputy director for the CDC's Science and Public Hhealth Program.
Schuchat said the public can take precautions to slow disease spread by reducing travel, washing hands, and staying home when sick.
