The cases of children with H1N1 influenza jumped significantly last week, but adults will soon feel more effects from the fast-spreading flu, health officials said this week. Philadelphia Health Commissioner Donald Schwartz said the city was tracking H1N1 cases to prevent unnecessary infections and provide vaccines for those most vulnerable to the flu. The city has about 635 confirmed H1N1 cases and another nine possible cases as of Wednesday, according to the state Department of Health Web site.
