Highlights • The novel coronavirus (COVID-19) pneumonia has caused 355 confirmed cases on the Diamond Princess cruise ship as of February 16, 2020.• We estimated that the Maximum-Likelihood (ML) value of reproductive number (R0) was 2.28 for COVID-19 outbreak at the early stage on the ship.• If R0 value was reduced by 25% and 50%, the estimated total number of cumulative cases would be reduced from 1296 (1145–1452) to 874 (780–978) and 573 (512–644) as of February 26, 2020, respectively.
