More than 83% of hospital workers had been vaccinated against seasonal flu by early November, the highest rate in any health care setting, according to a survey released today by the Centers for Disease Control and Prevention. About 63% of all health care personnel had been vaccinated by early November, about the same rate as in the prior flu season. Workers in long-term care facilities had the lowest mid-season vaccination rate (48.7%). The most common reason health care workers reported for not getting vaccinated was that they did not want to, and the second was a belief that vaccination was ineffective. Fewer than half of U.S. children and adults were vaccinated by early to mid-November, also about the same as last flu season, CDC said. This is National Flu Vaccination Week. According to CDC, the proportion of outpatient visits for flu-like illness were at the national baseline of 2.2% in the week ending Nov. 24, the earliest the nation has hit that benchmark in the regular flu season since 2003-04. Five states reported a high-level of outpatient visits for flu-like illness: Alabama, Louisiana, Mississippi, Tennessee and Texas.
