Following the univariate analysis, logistic regression was used to investigate the factors effective on COVID-19 reinfection. Results: A total of 213768 patients had a positive Polymerase Chain Reaction (PCR) test. The reinfection rate was 0.97% (2079 patients). Of these re-infected individuals, ...
This systematic review and meta-analysis assesses reports of clinical experiences of patients with COVID-19 and immunosuppression who were treated with
The interval between episodes, as measured from recovery until reinfection, ranged from 19 to 57 days, which is well below the average. Two of the cases were in critical condition during the first episode while the other four were described as “moderate.” The reinfection was mild in at lea...
We fit a susceptible-exposed-infectious-recovered (SEIR)-based model with a time-varying transmission rate to the reported COVID-19 deaths for the twelve South American countries with the highest mortalities. Most of the epidemiological datasets analysed in this work are retrieved from the disease ...
The CDC is investigating how often reinfections occur, who is at higher risk of reinfection, how soon reinfections take place after a previous infection, and the severity of reinfections compared with initial infections. Past Coronaviruses
More than 74.30 million confirmed cases of the COVID-19 have been reported globally so far, with an average fatality rate of almost 3.0%. Seven different types of coronaviruses had been detected from humans; three of them have resulted in severe outbreaks, i.e., MERS-CoV, SARS-CoV, and...

The northern state of Amazonas is among the regions in Brazil most heavily affected by the COVID-19 epidemic and has experienced two exponentially growing waves, in early and late 2020. Through a genomic epidemiology study based on 250 severe acute respiratory syndrome coronavirus 2 (SARS-CoV...
"The rate of reinfection with these variants is also dramatically increased and prevalence is increasing across all ages. This highlights the ability of these viruses to evade antibody immunity and the rapidity with which they are causing waves across the globe is concerning," the virologist said....
