On 5 February 2020, in Yokohama, Japan, a cruise ship hosting 3,711 people underwent a 2-week quarantine after a former passenger was found with COVID-19 post-disembarking. As at 20 February, 634 persons on board tested positive for the causative virus. We conducted statistical modelling to derive the delay-adjusted asymptomatic proportion of infections, along with the infections’ timeline. The estimated asymptomatic proportion was 17.9% (95% credible interval (CrI): 15.5–20.2%). Most infections occurred before the quarantine start.

- Occurrence and transmission potential of asymptomatic and presymptomatic SARS-CoV-2 infections: A living systematic review and meta-analysis (2020, positive): “We included 79 studies that reported empirical data about 6,616 people with SARS-CoV-2 infection (1,287 defined as having asymptomatic infection) [17,18,21–23,26–28,31,32,34,36, 39–45,47–50,52–54,56–62,64,66–68,70–77,79–90,92–112,114] and one statistical modelling study [24] (Table 1).”
- Mapping the Landscape of Artificial Intelligence Applications against COVID-19 (2020, methodology): “A more case-specific application of such methods is employed by Mizumoto et al. (2020), who seek to understand the rate of asymptomatic cases using data on 634 confirmed cases collected during the COVID-19 outbreak on board the Diamond Princess cruise ship.”
- SARS-CoV-2 in wastewater: State of the knowledge and research needs (2020, neutral): “SARS-CoV-2 is known to cause asymptomatic or pauci-symptomatic infections (Lai et al., 2020; Mizumoto et al., 2020; Nishiura et al., 2020; A. Tang et al., 2020a) making it difficult to determine the actual degree of viral circulation in a community and in making comparisons among different…”
