Clinical and nonclinical health care workers faced a similar risk of acquiring 2009 pandemic H1N1 infection

Clin Infect Dis. 2011 Aug 1;53(3):280-3. doi: 10.1093/cid/cir375.


Reporting of confirmed pandemic influenza A virus (pH1N1) 2009 infection was mandatory among health care workers in Hong Kong. Among 1158 confirmed infections, there was no significant difference in incidence among clinical versus nonclinical staff (relative risk, 0.98; 95% confidence interval, 0.78-1.20). Reported community exposure to pH1N1 was common and was similar in both groups.
