Classically, endemic infectious diseases are expected to display relatively stable, predictable infection dynamics. Accordingly, basic disease models such as the susceptible-infected-recovered-susceptible model stable states or recurrent seasonal waves. However, if human population reacts high numbers by mitigating spread of disease, then this delayed behavioral feedback loop can generate waves itself, driven periodic mitigation and subsequent relaxation. We show that reactions, together with a effect comparable impact, cause complex unpredictable dynamics, including Arnold tongues, coexisting attractors, chaos. Importantly, these arise in epidemiologically relevant parameter regions where costs associated infections jointly minimized. By comparing our data, we find signs COVID-19 was mitigated way favored Our results challenge intuition dynamics necessarily implies predictability emergence when humans optimize their reaction increasing numbers.

The ongoing COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a global threat. Despite strict control measures implemented worldwide and immunization using novel vaccines, the continues to rage due emergence of several variants SARS-CoV-2 with increased transmission immune escape. rapid spread concern (VOC) in recent past created massive challenge for via currently used vaccines. Vaccines that are safe effective against current future essential controlling pandemic. Rapid production rollout next-generation vaccines key steps help us return normality. Coordinated surveillance SARS-CoV-2, redesign new extensive vaccination needed counter prevent variants. In this article, we review latest information on VOCs interest (VOIs) present clinical trials underway evaluating effectiveness VOCs.

The introduction of COVID-19 vaccination passes (VPs) by many countries coincided with the Delta variant fast becoming dominant across Europe. A thorough assessment their impact on epidemic dynamics is still lacking. Here, we propose VAP-SIRS model that considers possibly lower restrictions for VP holders than rest population, imperfect effectiveness against infection, rates (re-)vaccination and waning immunity, fraction never-vaccinated, increased transmissibility variant. Some predicted scenarios realistic parameter values yield new infection waves within two years, high daily case numbers in endemic state, even without introducing VPs granting more freedom to holders. Still, suitable adaptive policies can avoid unfavorable outcomes. While could initially be allowed freedom, lack full vaccine will require accelerated (re-)vaccination, wide-spread immunity surveillance, and/or minimal long-term common restrictions.

Abstract As coronavirus variants are constantly occurring, we tried to understand more about the omicron and delta that have hit world. We provided dynamic information on case fatality rate (CFR) of Omicron variant over time compare it with Delta through meta‐analysis. Twenty‐four countries were selected by submission counts, dates, confirmed cases. defined or epidemic period for individual as when each is 90%. further analyzed dividing into initial plateau, increasing, decreasing phases according number newly daily Finally, meta‐analysis examined summary between‐study heterogeneity. The CFR COVID‐19 during was lower than (odds ratio [OR]: 0.252, 95% confidence interval [CI] 0.205−0.309). plateau phase higher other phases. (OR: 1.962, CI 1.607−2.397). increasing 0.412, 0.342–0.498). had compared variant, noninitial These results can help establish global health policies in future.
