This number can change from day-to-day and from location to location. Research published late yesterday in The New England Journal of Medicine offers another estimate of the R-nought (R 0) value—a measure of infectiousness—of the novel coronavirus (2019-nCoV) that has sickened more than 8,000 people and suggests the virus is more infectious than the 1918 influenza pandemic virus. This is the first study to quantify the basic reproduction number, R , of 2019-nCoV in the early phase of the outbreak. Per 1/21/2020 CDC update, "CDC has developed a real time Reverse Transcription-Polymerase Chain Reaction (rRT-PCR) test that can diagnose 2019-nCoV.

An estimated 151,700 to 575,400 people died from the virus across the globe, according to the Centers for Disease Control and Prevention. For starters the Ro (pronounced R naught) is actually around 6, not 3. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), of an infection can be thought of as the expected number of cases directly generated by one case in a population where all individuals are susceptible to infection. So R-naught (R0) goes down by an estimated. Initial estimates of the early dynamics of the outbreak in Wuhan, China, suggested a doubling time of the number of infected persons of 6–7 days and a basic reproductive number (R 0) of 2.
