By 31 May 2022, original/Alpha, Delta and Omicron strains induced 101 outbreaks of COVID-19 in mainland China. Most were cleared by combining non-pharmaceutical interventions (NPIs) with vaccines, but continuous virus variations challenged the dynamic zero-case policy (DZCP), posing questions what are prerequisites threshold levels for success? And independent effects vaccination each outbreak? Using a modified classic infectious disease model an iterative relationship new infections per...
Overcompensation, defined as recovery beyond a baseline state, arises from both hormetic and hydra effects, illustrating adaptive responses to stress. The overcompensation framework of re-evaluated fishery resource management model was examined through nonlinear growth patterns based on logistic or Ricker models, emphasizing population size over carrying capacity. This complete model’s threshold conditions reveal an interplay between effects. Also, when dividing into distinct subgroups, such...
After a major outbreak of the coronavirus disease (COVID-19) starting in late December 2019, there were no new cases reported mainland China for first time on March 18, 2020, and Hong Kong Special Administrative Region April 20, 2020. However, these places had experienced second wave since June 11, Here we develop stochastic discrete-time epidemic model to evaluate risk COVID-19 resurgence by analyzing data from beginning three places. In model, use an input parameter represent few potential...
