Elton John, who is recovering in a London Hospital from E. Coli is also being treated for influenza. Flu has caused the prominent British singer to postpone many European concerts as well as two concerts in Seattle and Portland.

The Dancing with the Stars cast work hard to try to avoid injuries while performing but it seems they can't prevent the flu from taking them off the dance floor. Dancers Lacey Schwimmer Derek Hough and Mark Ballas were all feeling the effects of the flu this week. While not confirmed to be the H1N1 Swine Flu virus, the three Dancing with the Stars performers were definitely feeling dismal.

A new study just published in the journal Pediatrics has found that probiotics may be able to bolster the immune system in children well enough to ward off cold and flu viruses.

Amid reports that swine flu viruses are developing the ability to shrug off existing antiviral drugs, scientists in Japan are reporting a first-of-its kind discovery that could foster a new genre of antivirals that sidestep resistance problems, according to an article scheduled for the July 23 issue of the ACS' Journal of the Medicinal Chemistry, a bi-weekly publication.

Researchers at the University of Rochester have developed a mathematical model to predict immune responses to infection with influenza A viruses, including novel viruses such as the emergent 2009 influenza A (H1N1).

A team of Princeton University scientists may have found a better way to make a vaccine against the flu virus. Though theoretical, the work points to the critical importance of what has been a poorly appreciated aspect of the interaction between a flu virus and those naturally produced defensive proteins called antibodies that fight infection.

A disease spread simulation has emphasized that flu interventions must be imposed quickly, if they are to be effective. Researchers writing in the open access journal BMC Public Health have shown that staying at home, closing schools and isolating infected people within the home should reduce infection, but only if they are used in combination, activated without delay and maintained for a relatively long period.

Vice President Joe Biden tells The Today Show's Matt Lauer: "I told family to avoid planes, subway over swine flu." He also said "I wouldn't go anywhere in confined places."

The swine flu virus disease in Mexico has killed almost 70 people and has now spread to the United States.

Researchers at Rhode Island Hospital have completed a study to better understand the impact of infection control measures during a possible flu pandemic.

Dieters or those who consume fewer calories during flu season could have a harder time fighting off the flu virus, according to research by Michigan State University nutritional immunology professor Elizabeth Gardner.

A new study by researchers at Yale School of Medicine could explain why the cold and flu virus symptoms that are often mild and transient in non-smokers can seriously sicken smokers. Published in the Journal of Clinical Investigation, the study also identified the mechanism by which viruses and cigarette smoke interact to increase lung inflammation and damage.
