Ascertainment rate of novel coronavirus disease (COVID-19) in Japan
As of March 1, 2020, a total of 58 countries had reported at least one confirmed case of novel coronavirus disease (COVID-19), and the cumulative number of deaths had reached 2977 persons across the world (WHO, 2020). To achieve appropriate countermeasures, it is vital to understand the current epidemiological situations of the COVID-19 epidemic.Epidemic update of COVID-19 in Hubei Province compared with other regions in China
Since the first atypical pneumonia case, caused by a novel coronavirus was reported in Wuhan, China on December 31, 2019 (WHO, 2020a), the novel coronavirus infection outbreak quickly spread in Wuhan, the capital of Hubei Province and other districts of Hubei Province with a further spread across the Chinese mainland. By 29 Feb 2020 a total of 79,824 cases of infection had been confirmed nationwide including all administrative regions, with another 851 suspected cases. COVID-19 cases were also reported in Thailand, Japan, the Republic of Korea, Hong Kong, Taiwan, the US, and some countries in Europe (CCDCPC, 2019).COVID-19: Four Paediatric Cases in Malaysia

Coronaviruses (CoVs), a large family of single-stranded RNA viruses, can infect animals and also humans, causing respiratory, gastrointestinal, hepatic, and neurologic diseases (Weiss and Leibowitz, 2013). As the largest known RNA viruses, CoVs are further divided into four genera: alpha-coronavirus, beta- coronavirus, gamma-coronavirus and delta-coronavirus (Yang and Leibowitz, 2015). To date, there have been six human coronaviruses (HCoVs) identified, including the alpha-CoVs HCoVs-NL63 and HCoVs-229E and the beta-CoVs HCoVs-OC43, HCoVs-HKU1, severe acute respiratory syndrome-CoV (SARS-CoV) (Drosten et al., 2020), and Middle East respiratory syndrome-CoV (MERS-CoV) (Zaki et al., 2012).Serial interval of novel coronavirus (COVID-19) infections
The epidemic of novel coronavirus (COVID-19) infections that began in China in late 2019 has rapidly grown and cases have been reported worldwide. An empirical estimate of the serial interval—the time from illness onset in a primary case (infector) to illness onset in a secondary case (infectee)—is needed to understand the turnover of case generations and transmissibility of the disease (Fine, 2003). Estimates of the serial interval can only be obtained by linking dates of onset for infector-infectee pairs, and these links are not easily established.Estimation of the reproductive number of novel coronavirus (COVID-19) and the probable outbreak size on the Diamond Princess cruise ship: A data-driven analysis
A novel coronavirus (COVID-19), which originated from Wuhan, China, has spread to 25 countries worldwide. Up to February 16, 2020, the cumulative number of confirmed cases were 70548 in China (National Health Commission of the People’s Republic of China, 2020) and 683 in other countries (World Health Organization, 2020). The whole world, especially China, has taken extraordinary measures to contain the outbreak of COVID-19, and the effects were already present.
