Reproductive Number (R0 "R Naught") showing how contagious / transmissible a pathogen is. The R0 for Wuhan nCoV2019 novel coronavirus: 1.4 - 3.3. Here are the figures for other diseases (SARS, MERS, Ebola) and their case-fatality rates to put things in perspective: Diphtheria R0 6-7 Fatality 5-10 % Ebola R0 1.5-2.5 Fatality 25-90 % Seasonal flu R0 1-2 Fatality <0.1 % Measles R0 12-18 Fatality 0.1-0.2 % Mumps R0 4-7 Fatality 0.01 % Pertussis (whooping cough) R0 12-17 Fatality 4% Polio R0 5-7 Fatality 5-10% (paralytic polio) Rubella R0 5-7 Fatality 3-6% (developing countries) SARS coronavirus R0 3 Fatality 11% MERS coronavirus R0 <1 Fatality 30-40 % 2019 novel coronavirus R0 1.4-3.3** Fatality 2-3% ** 'Ro value does not take into account case-fatality rate.
