RESUMO
OBJECTIVES: The aim of this study was to characterize overlooked cases of patients with monkeypox infection in the 2022 outbreak. METHODS: Clinical characteristics of 26 patients who were misdiagnosed with other diseases were described. RESULTS: Of the 26 patients who were misdiagnosed, six (23%) were given a diagnosis of bacterial tonsillitis, six (23%) were diagnosed with primary syphilis, five (19.2%) with oral or genital herpes, and four (15.3%) with bacterial proctitis or anal abscess. The average time interval between missed and right diagnosis was 4.4 days. There was no difference in the missed cases between the early and the later month of the outbreak. CONCLUSION: Monkeypox might still be commonly overlooked, especially in patients presenting with fever and sore throat or solitary ulcer as sole manifestations.

The current monkeypox virus global spread and lack of data regarding clinical specimens' infectivity call for examining virus infectivity, and whether this correlates with results from PCR, the available diagnostic tool. We show strong correlation between viral DNA amount in clinical specimens and virus infectivity toward BSC-1 cell line. Moreover, we define a PCR threshold value (Cq ≥ 35, ≤ 4,300 DNA copies/mL), corresponding to negative viral cultures, which may assist risk-assessment and decision-making regarding protective-measures and guidelines for patients with monkeypox.
