[Abstract]:A
basic reproductive number Ro is an important
index in dynamics of a newly emerged
and rapidly growing infectious disease
outbreak, such as COVID-19. However, the
current researches indicated that Ro for
COVID-19 is quite affected by many other
factors or parameters.
To
find the alternative index for the
reality of spread of the COVID-19, a
study based on the population of
2,067.14 millions from seven countries,
USA, UK, Brazil, India, South Africa,
Canada and Sweden, was conducted and the
weekly new case ratio as index for
mathematical method or anticipatable
formula for application was introduced.
In addition, it could be used for
evaluating Ro value and setting a
methodological formula or index for
other contagious disease in the future.
