Providing preventive Tamiflu and educating and emphasizing the need for repeated hand sanitizer use and disinfectant spray helped stop the spread of H1N1 influenza at a boys' summer camp in northern Alabama, according the co-director of the University of Alabama at Birmingham (UAB) Division of Pediatric Infectious Diseases.

Ordinary face masks and hand hygiene can effectively reduce the transmission of influenza-like illness during flu season. The finding comes from a new study, now available online, published in the Feb. 15 issue of The Journal of Infectious Diseases. In an influenza pandemic, vaccination may not be initially available, and antiviral prescribing may be limited, which is why scientists need to understand how effective other measures are in preventing influenza.

Lessons learned from the first 13 children at Johns Hopkins Children's Center to become critically ill from the H1N1 virus show that although all patients survived, serious complications developed quickly, unpredictably, with great variations from patient to patient and with serious need for vigilant monitoring and quick treatment adjustments.

These and other findings were published online on Dec. 31 in the journal Pediatric Critical Care Medicine, in what is believed to be the first published analysis of critical H1N1 illness in children.

Supplies of the H1N1 (swine flu) vaccine are steadily increasing in the U.S. and should soon be more widely accessible in the next two weeks, the CDC said on Tuesday, CQ HealthBeat reports. During a press briefing, CDC Director Thomas Frieden said that 22.4 million vaccine doses are now available for states to order (Norman, 10/27). "We're beginning to get to significant increases in the availability," Frieden said.
