MILWAUKEE (AP) - A hundred cases of swine flu in the U.S.? Health officials say there are likely more. Just how many is not important, they say. As the world faces a potential pandemic, swamped labs are not testing all possible cases. Getting an exact tally has taken a back seat to finding new outbreak hot spots or ways to limits its spread, health officials said. "The specimens are coming in faster than they can possibly be tested," said Dr. Jeffrey P. Davis, state epidemiologist in Wisconsin, where a lab helped spot the nation's first known case, in a 10-year-old boy from San Diego. New York, which has more cases than any other U.S. location, also has had to limit the samples it tests, said Dr. Don Weiss of that city's health department. "Sure, we'd want to diagnose every case, but we don't have that resource," he said. Instead of trying to confirm every sign of the virus, "we're focused on where else is it going and how do we prevent it."

Notice that news out of mexico is pretty sparse today???
Earlier there was some...their lock down has brought news to a halt it appears...and canada made a announcement earlier that they were going to .gov flu announcements as well...Hmmm...

I think we all need to do guerilla blogging. Get webcams out there on interstates, hidden in trees and see how they start deploying troops, ahead of announcements. That is definitely why they are paving the way for the calm before the storm.
I miss spoke myself and I apologize. You are right the flu vaccine is compiled of both A and B strains.

The only flu epidemics we have experienced are Influenza B strains. This is also the only type of flu we have immunity to due to years of flu injections, or having influenza.
I beg to question this. 1957 was A flu as was 1918 [tho it may have been a mix] and most flu strains that infect humans are avian.
Last years flu vaccine had 2 A flu strains and 1 B strain. There is an A strain in the vaccine every year.
I am just quoting fact. I don't take the vaccine myself.
There is no evidence of efficient human-to-human transmission or of airborne transmission of HPAI A(H5N1) to humans. In almost all cases, those infected with H5N1 had extensive physical contact with infected birds. Still, around 60% of humans known to have been infected with the current Asian strain of HPAI A(H5N1) have died from it, and H5N1 may mutate or reassort into a strain capable of efficient human-to-human transmission.
Influenza viruses change constantly. Pigs can be infected by avian, human and swine viruses. When influenza viruses from different species infect pigs, the viruses can swap genes (“reassort”) and new viruses that are a mix of swine, human and/or avian influenza viruses can emerge. The recent outbreak of swine flu in April 2009 referred to as H1N1, is caused by a new virus containing a mixture of virus genes never seen before. Unlike typical swine flu, the new virus can spread from person-to-person.
I’ve already had my flu shot (vaccine) – am I protected? This H1N1 swine flu is a new form of virus and the vaccine will not protect you, although the vaccine is still highly recommended since it will help prevent the common flu. If you are infected with this new swine flu virus, there are drugs that are effective in treating the illness.
What is pandemic influenza? Pandemic influenza (pandemic flu) is a worldwide outbreak of respiratory disease caused by a new flu virus that people have not been exposed to before. Because our bodies would have no resistance to this new virus, it could spread quickly from person-to-person and cause serious illness. What causes pandemic flu viruses? Flu viruses have the ability to change,and any flu virus can mutate into a new form.These new viruses can infect people,spread rapidly from person-to-person and cause serious illness. The flu vaccines currently used by the medical community will not be effective in preventing this new virus from causing illness. If the illness spreads around the world, a pandemic could result.
Avian Influenza Viruses
Avian (bird) flu is caused by influenza A viruses that occur naturally among birds. There are different subtypes of these viruses because of changes in certain proteins (hemagglutinin [HA] and neuraminidase [NA]) on the surface of the influenza A virus and the way the proteins combine.
Each combination represents a different subtype. All known subtypes of influenza A viruses can be found in birds. The avian flu currently of concern is the H5N1 subtype.
"Human influenza virus" usually refers to those subtypes that spread widely among humans. There are only four known A subtypes of influenza viruses (H1N1, H1N2, H3N2, and H7N2) currently circulating among humans. It is likely that some genetic parts of current human influenza A viruses originally came from birds. Influenza A viruses are constantly changing, and other strains might adapt over time to infect and spread among humans. The risk from avian influenza is generally low to most people, because the viruses do not usually infect humans. H5N1 is one of the few avian influenza viruses to have crossed the species barrier to infect humans, and it is the most deadly of those that have crossed the barrier.
An effort to recreate the 1918 flu strain (a subtype of avian strain H1N1) was a collaboration among the Armed Forces Institute of Pathology, Southeast Poultry Research Laboratory and Mount Sinai School of Medicine in New York; the effort resulted in the announcement (on October 5, 2005) that the group had successfully determined the virus's genetic sequence, using historic tissue samples recovered by pathologist Johan Hultin from a female flu victim buried in the Alaskan permafrost and samples preserved from American soldiers.
