A small survey of St. Louis-area physicians found doctors greatly overestimate the prevalence of Lyme disease and underestimate the prevalence of other tick-borne illnesses in Missouri.
Scientists at the University of Southern Illinois-Edwardsville sent a survey to 81 St. Louis-area infectious-disease specialists and family physicians. About a fifth of the doctors responded.
According to the results, published earlier this month in the journal Ticks and Tick-borne Diseases, 82 percent of respondents believed Lyme disease was among the most common tick-borne infections in the state. But state health officials say there were only 10 probable or confirmed cases of Lyme in Missouri in 2016.
