Study profiles Aussie hospital cases
Australian researchers who studied hospitalized H1N1 flu patients in seven Melbourne hospitals from May to mid July report that 30 of 112 patients (27%) required intensive care and 3 died. Patients who had multifocal changes on chest x-rays were hospitalized longer and were more likely to need intensive care, according to the Medical Journal of Australia. Twenty-four patients had no known risk factors. Fifteen patients—a quarter of the women—were pregnant or in the postpartum period.

Disparity between H1N1 and seasonal flu deaths explored
A Canadian Press report probed the wide difference between the numbers of H1N1 flu deaths reported so far and the estimated toll from seasonal flu. Canada, with 4,000 to 8,000 flu-related deaths yearly, has 161 confirmed H1N1 deaths. Experts note that those numbers count different things, because only a small fraction of all seasonal flu–related deaths are directly attributed to flu. In most cases, flu contributes to death from such direct causes as bacterial pneumonia or heart attack.

The study was based on the results of focus groups in four Michigan cities. The authors said more intense efforts are needed to engage the public in pandemic planning.

WHO notes pandemic-related TB challenges
Because many H1N1-related deaths have involved people with chronic respiratory conditions, the World Health Organization (WHO) recently issued a statement to alert tuberculosis (TB) program managers to possible "challenges and synergies" in the effort to control the two diseases. The statement stresses the importance of maintaining TB treatment during a pandemic and notes that lab services developed for TB control can be useful for pandemic H1N1 diagnostics and surveillance.

Delays faulted in Ukraine's severe cases
Factors such as delays in seeking medical care and getting antiviral medication to outbreak areas contributed to a sudden spike in severe flu-related pneumonia cases in the Ukraine, the New York Times reported. The late-October surge in flu-like illnesses prompted a WHO probe, which found the patterns in line with other countries. Doctors blame the news media and politicians for spreading misinformation, while others say a weak healthcare system played a role.
