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.COVID-19: Four Paediatric Cases in Malaysia
This is a brief report of 4 paediatric cases of COVID-19 infection in MalaysiaSerial 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.
