Background

On 12 January 2020, the World Health Organization (WHO) confirmed that a novel coronavirus was the cause of a respiratory illness in a cluster of people in Wuhan City, Hubei Province, China, which was reported to the WHO on 31 December 2019.[4][5]

The case fatality ratio for COVID-19 has been much lower than SARS of 2003,[6][7] but the transmission has been significantly greater, with a significant total death toll.[8][6] Model-based simulations for Chad indicate that the 95% confidence interval for the time-varying reproduction number R t for Chad has been stable below 1.0 since April.[9]
