Physician Knowledge, Attitudes, and Practices Regarding Viral Exanthem Diagnosis And Mandatory Reporting Requirements in Major Metropolitan Regions of Florida, USA

Objective To evaluate physician knowledge, attitudes, and practices regarding viral exanthem diagnosis and mandatory reporting requirements among practicing physicians in major metropolitan regions of Florida. Study Design An IRB-exempt cross-sectional survey was distributed via REDCap to licensed physicians and residents in family medicine, internal medicine, pediatrics, and infectious disease across Florida. The 19-question survey assessed demographic characteristics, knowledge of viral exanthem diagnosis (measles, rubella, roseola), reporting requirements, physician attitudes, and clinical practices. Knowledge scores were compared by specialty using ANOVA with Tukey post-hoc analysis. Multivariate analysis and linear regression assessed associations between physician confidence and knowledge scores. Results A total of 162 physicians responded, with 146 complete responses included in analysis. Participants included pediatrics (n=74), family medicine (n=48), and internal medicine (n=24). The overall mean knowledge score was 78.5% (SD 20.5). Pediatricians demonstrated the highest scores (82.7%) compared with internal medicine (76.4%) and family medicine (73.3%), with pediatricians scoring significantly higher than family physicians (p=0.04). Differences in vignette-based diagnostic knowledge and mandatory reporting knowledge were not statistically significant across specialties. Roseola was the most commonly diagnosed viral exanthem (66%), followed by measles (30%) and rubella (17%). Most physicians (91.4%) expressed interest in additional training. Conclusions Although overall physician knowledge of viral exanthem diagnosis and reporting was high, clinically meaningful gaps remain, particularly in differentiating similar rash presentations. Pediatricians demonstrated higher knowledge scores than family physicians. Enhanced physician education may improve diagnostic accuracy and public health reporting as vaccination rates decline and outbreaks of vaccine-preventable viral exanthems increase.
