Short-term predictions of country-specific Covid-19 infection rates based on power law scaling exponents

Understand

The number of corona virus (COVID-19) infections grows worldwide.

• In order to create short term predictions to prepare for the extent of the global pandemic we analyze infection data from the top 25 affected countries.
• It is shown that all country-specific infection rates follow a power law growth behavior and the scaling exponents per country are calculated.
• We find two different growth patterns: either steady power law growth from the very beginning with moderate scaling exponents of 3-5 or explosive power law growth with dramatic scaling exponents of 8-11.
