This effort has been successful at building a regional surveillance system. In the 2010, three pilot hospital sites were enrolled to conduct severe acute respiratory infection (SARI) surveillance. These patients were tested for viral, bacterial and important fungal infections that cause respiratory disease. Fig. 1 includes results of the 74 hospitalized SARI patients who were enrolled in the 2010Á2011 influenza season. The SARI patients were 54% (n040) male and had a median age of was 62.5 years (range, 0Á 87 years). The expansion of this surveillance system requires additional sentinel hospital-sites and additional syndromes. A syndrome of acute diarrheal illness will be the focus of surveillance at one new pilot sentinel site, with potential to expand in the future.
