Multi-strain COVID-19 dynamics with vaccination strategies: mathematical modeli...
Ambalarajan, Venkatesh; Mallela, Ankamma Rao; Dhandapani, Prasantha Bharathi; Sivakumar, Vinoth; Leiva, Víctor; Castro, CeciliaThe emergence of alpha, beta, gamma, and delta COVID-19 variants has posed important challenges to global health. Understanding the transmission dynamics and evaluating the impact of vaccination strategies are critical for effective pandemic management. The present study develops a novel mathematical model that incorporates time-dependent vaccination rates to analyze the spread of these four COVID-19 variants, ...
A six-compartment model for COVID-19 with transmission dynamics and public heal...
Ambalarajan, Venkatesh; Mallela, Ankamma Rao; Sivakumar, Vinoth; Dhandapani, Prasantha Bharathi; Leiva, Víctor; Martin-Barreiro, Carlos; Castro, CeciliaThe global crisis of the COVID-19 pandemic has highlighted the need for mathematical models to inform public health strategies. The present study introduces a novel six-compartment epidemiological model that uniquely incorporates a higher isolation rate for unreported symptomatic cases of COVID-19 compared to reported cases, aiming to enhance prediction accuracy and address the challenge of initial underreporti...
