Phys .org: Correlations in COVID-19 growth point to universal strategies for slowing spread. “Researchers in Brazil analyzed the growth of confirmed infected COVID-19 cases across four continents to better characterize the spread of the virus and examine which strategies are effective in reducing its spread. Their results, published in Chaos, found the virus commonly grows along a power law curve, in which the social, economic and geographical features of a particular area affect the exponent to which the infection spreads rather than affecting traits of the infection itself.”
