Reports Summarize Mathematics Findings from Ruhr-University Bochum (Mathematics of Epidemics: On the General Solution of Sirvd, Sirv, Sird, and Sir Compartment Models).

A report from Ruhr-University Bochum in Germany discusses the mathematics of epidemics and the development of compartment models to understand the effects of vaccination campaigns and time-dependent fatality rates on epidemic outbreaks. The researchers investigate exact solutions and analytical approximations for these models, which are important for understanding the critical behavior of epidemics and the role of certain parameters. The study also applies an analytical approximation to calculate epidemic quantities in the context of COVID-19 data. The research provides valuable insights for public health and epidemiology.
