Duration of immune protection of SARS-CoV-2 natural infection against reinfection.
( Oxford University Press , 2022 , Article)The future of the SARS-CoV-2 pandemic hinges on virus evolution and duration of immune protection of natural infection against reinfection. We investigated duration of protection afforded by natural infection, the effect ... -
Effectiveness of the neutralizing antibody sotrovimab among high-risk patients with mild-to-moderate SARS-CoV-2 in Qatar
( Elsevier , 2022 , Article)ObjectivesTo estimate the real-world effectiveness of sotrovimab against severe, critical, or fatal COVID-19 in Qatar at a time in which most SARS-CoV-2 incidences occurred due to the BA.2 Omicron subvariant. MethodsWe ... -
Effects of BA.1/BA.2 subvariant, vaccination, and prior infection on infectiousness of SARS-CoV-2 omicron infections.
( Oxford University Press , 2022 , Article)Compared to BA.1, BA.2 was associated with lower RT-qPCR cycle threshold (Ct) value-3.53 fewer cycles (95% CI: 3.46-3.60), signifying higher infectiousness. This may reflect higher viral load and/or longer duration of ... -
Emerging COVID-19 variants and their impact on SARS-CoV-2 diagnosis, therapeutics and vaccines
( Taylor and Francis , 2022 , Article)The emergence of novel and evolving variants of SARS-CoV-2 has fostered the need for change in the form of newer and more adaptive diagnostic methods for the detection of SARS-CoV-2 infections. On the other hand, developing ... -
How did the COVID-19 pandemic impact consumers' food safety knowledge, attitudes and practices? A multi-country study on the omicron variant
( Emerald Publishing , 2024 , Article)Purpose: The COVID-19 pandemic is not a foodborne infectious disease, but it has dramatically impacted food safety practices worldwide due to its potential for transmission through contaminated surfaces and food. Accordingly, ... -
Impact of COVID-19 on food behavior and diet in Qatar: A cross-sectional survey on the Omicron variant
( SAGE Publications Ltd , 2023 , Article)Purpose: The emergence of the Omicron variant in November 2021 appears to have impacted food-related activities and behaviors and caused disruptions in food supply systems. Accordingly, this article aims to explore the ... -
Increased Receptor Affinity and Reduced Recognition by Specific Antibodies Contribute to Immune Escape of SARS-CoV-2 Variant Omicron
( MDPI , 2022 , Article)In this report, we mechanistically reveal how the Variant of Concern (VOC) SARS-CoV-2 Omicron (B.1.1.529) escapes neutralizing antibody responses, by physio-chemical characterization of this variant in comparison to the ...
