At least the cases of swine flu in the United States have been mild umlike the killer strain of the virus in Mexico.
The U.S. declared a public health emergency Sunday to deal with the emerging new swine flu, much like the government does to prepare for approaching hurricanes.
Officials reported 20 U.S. cases of swine flu in five states so far, with the latest in Ohio and New York. Unlike in Mexico where the same strain appears to be killing dozens of people, cases in the United State have been mild — and U.S. health authorities can't yet explain why.
"As we continue to look for cases, we are going to see a broader spectrum of disease," predicted Dr. Richard Besser, acting chief of the Centers for Disease Control and Prevention. "We're going to see more severe disease in this country."
At a White House news conference, Besser and Homeland Security Secretary Janet Napolitano sought to assure Americans that health officials are taking all appropriate steps to minimize the impact of the outbreak.
Top among those is declaring the public health emergency. As part of that, Napolitano said roughly 12 million doses of the drug Tamiflu will be moved from a federal stockpile to places where states can quickly get their share if they decide they need it. Priority will be given to the five states with known cases so far: California, Texas, New York, Ohio and Kansas.
And, the cause of this outbreak has been
linked to Smithfield Factory Farms in Mexico.The outbreak of a new flu strain—a nasty mash-up of swine, avian, and human viruses—has infected 1000 people in Mexico and the U.S., killing 68. The World Health Organization warned Saturday that the outbreak could reach global pandemic levels. Is Smithfield Foods, the world’s largest pork packer and hog producer, linked to the outbreak? Smithfield operates massive hog-raising operations Perote, Mexico, in the state of Vera Cruz, where the outbreak originated. The operations, grouped under a Smithfield subsidiary called Granjas Carrol, raise 950,000 hogs per year, according to the company Web site—a level nearly equal to Smithfield’s total U.S. hog production.
On Friday, the U.S. disease-tracking blog Biosurveillance published a timeline of the outbreak containing this nugget, dated April 6 (major tip of the hat to Paula Hay, who alerted me to the Smithfield link on the Comfood listserv and has written about it on her blog, Peak Oil Entrepreneur):
Residents [of Perote] believed the outbreak had been caused by contamination from pig breeding farms located in the area. They believed that the farms, operated by Granjas Carroll, polluted the atmosphere and local water bodies, which in turn led to the disease outbreak. According to residents, the company denied responsibility for the outbreak and attributed the cases to “flu.” However, a municipal health official stated that preliminary investigations indicated that the disease vector was a type of fly that reproduces in pig waste and that the outbreak was linked to the pig farms. It was unclear whether health officials had identified a suspected pathogen responsible for this outbreak.
Will the United States send public health officials to investigate this situation. In the meantime, the public health of the United States is at risk while the
United States was slow to learn of the Mexican flu.U.S. public health officials did not know about a growing outbreak of swine flu in Mexico until nearly a week after that country started invoking protective measures, and didn't learn that the deaths were caused by a rare strain of the influenza until after Canadian officials did.
The delayed communication occurred as epidemiologists in Southern California were investigating milder cases of the illness that turned out to be caused by the same strain of swine flu as the one in Mexico.
In the wake of the 2001 terrorist attacks, the outbreak of severe acute respiratory syndrome (SARS) in 2003 and the more recent emergence of H5N1 bird flu in Asia, national and local health authorities have done extensive planning for disease outbreaks that could lead to global epidemics, or pandemics. Open and frequent communication between countries and agencies has been a hallmark of that work.
Whether delayed communication among the countries has had a practical consequence is unknown. However, it seems that U.S. public health officials are still largely in the dark about what's happening in Mexico two weeks after the outbreak was recognized.
I, frankly, think that the United States and the Obama Administration know more about the situation in Mexico then they are communicating to the public. They probably did not want to start a panic or ruin companies doing business in Mexico.
But, they better get a handle on this, including closing the Mexican border before the swine flu becomes a pandemic and spreads throughout the United States.
Stay tuned......
