*DENV, dengue virus; RT-PCR, reverse transcription PCR. †Samples for PCR collected 1–12 days after symptom onset; samples for IgM collected 5–213 days after symptom onset. ‡Acute cases were tested within 7 days after symptom onset. Data include only persons medically evaluated by a healthcare provider in the United States. Information on care-seeking behavior was determined through case interview and laboratory records. Negative COVID-19 results were required to be reported to Florida Department of Health, but negative dengue laboratory results are not, which might have resulted in underreporting of commercial dengue testing among persons who sought care.
