Inﬂ uenza A(H1N1)
Seroprevalence of antibodies to inﬂ uenza A(H1N1)
pdm09 virus among 193 emergency department health care
personnel was similar among 147 non–health care person-
nel (odds ratio 1.4, 95% CI 0.8–2.4). Working in an acute
care setting did not substantially increase risk for virus infec-
tion above risk conferred by community-based exposures.
