'In this study, we estimated the serial interval by analyzing 109 pairs of laboratory-confirmed monkeypox in the Netherlands. After reviewing detailed exposure histories, we identified 34 pairs where the infectee reported a single potential infector. The mean serial interval for those 34 pairs was 10.1 days (95% CI: 6.6-14.7 days), suggesting a reproduction number between 1.3 and 1.6 during June 2022 in the Netherlands.'
