Incubation period of 2019 novel coronavirus (2019-nCoV) infections among travellers from Wuhan, China, 20-28 January 2020.
TL;DR: Using the travel history and symptom onset of 88 confirmed cases that were detected outside Wuhan in the early outbreak phase, the mean incubation period is estimated to be 6.4 days, which should help inform 2019-nCoV case definitions and appropriate quarantine durations.
Journal ArticleDOI
Estimated incubation period for monkeypox cases confirmed in the Netherlands, May 2022

TL;DR: The monkeypox incubation period was estimated, using reported exposure and symptom-onset times for 18 cases detected and confirmed in the Netherlands up to 31 May 2022, underpinning the current recommendation to monitor or isolate/quarantine case contacts for 21 days.
Journal ArticleDOI
Simultaneous inference of phylogenetic and transmission trees in infectious disease outbreaks
TL;DR: This work has developed a novel approach to reconstruct transmission trees with sequence data that combines elementary models for transmission, case observation, within-host pathogen dynamics, and mutation, under the assumption that the outbreak is over and all cases have been observed.
Journal ArticleDOI
Shorter serial intervals in SARS-CoV-2 cases with Omicron BA.1 variant compared with Delta variant, the Netherlands, 13 to 26 December 2021

TL;DR: The SARS-CoV-2 Omicron variant has a growth advantage over the Delta variant because of higher transmissibility, immune evasion or shorter serial interval, and within households, the mean serial interval for SGTF cases was 0.2–0.6 days shorter than for non-SGTF cases.

The incubation period of 2019-nCoV infections among travellers from Wuhan, China
TL;DR: Using the travel history and symptom onset of 88 confirmed cases that were detected outside Wuhan, the mean incubation period of a novel coronavirus 2019-nCoV is estimated to be 6.4 days, ranging from 2.1 to 11.1 days, to inform case definitions for 2019- nCoV and appropriate durations for quarantine.
