WHO: Flu continues climb in Northern Hemisphere

Activity is starting to increase in Europe and parts of Asia but is slowing in most of South America and Australia.

Poll finds limited interest in vaccine, growing H1N1 worry
Another poll has found lukewarm interest in getting the pandemic H1N1 vaccine. A Harvard survey found that 40% of adults were certain they'd get the shot and 51% were sure they'd get their kids vaccinated, slightly higher than in a recent Consumer Reports poll. The Harvard survey, conducted in mid September, indicated demand would surge if the virus caused local sickness and death. Seventy-six percent said they were concerned about more outbreaks, up from 59% in the summer.

Taiwanese flu case reports reveal viral pneumonia
A review of the medical records from the first 100 severe H1N1 cases in Taiwan, initially posted to an international listserv, reveals that complex illness tends to strike children and young adults who are obese or have other underlying conditions, including pregnancy. Twenty-three of the 100 patients required mechanical ventilation, 9 went on extra-corporeal membrane oxygenation (ECMO), and 9 died. In contrast to US data, 89 of the 100 had primary viral pneumonia.

Researchers name severe flu syndrome: FLAARDS
Australian and New Zealand researchers have dubbed the direst manifestation of H1N1 flu "FLAARDS," for "flu A-associated acute respiratory disease syndrome," according to Bloomberg News. In a medical journal editorial, intensive-care specialists Drs. Steven Webb and Ian Seppelt describe inflamed, flooded lungs requiring mechanical ventilation or ECMO, sometimes leading to multi-organ failure and death. Bacterial pneumonias and underlying chronic conditions also play a role, they said.

European agency endorses Baxter's cell-based vaccine
The European Medicines Agency (EMEA) today recommended approval of Baxter's cell culture-based H1N1 vaccine, Celvapan, for use in the European Union. The move follows similar verdicts last week on H1N1 vaccines from Novartis and GlaxoSmithKline. EMEA recommendations are usually adopted by the European Commission. Baxter said Celvapan is the first cell-based, non-adjuvanted H1N1 vaccine to get the EMEA's endorsement. The EMEA is recommending two doses of the vaccine for both adults and children.
