The effects of mutations in continuously emerging variants of SARS-CoV-2 are a major
concern for the performance of rapid antigen tests. To evaluate the impact of mutations on …

Importance Variants of SARS-CoV-2 have sequence variations in the viral genome that may
alter the accuracy of rapid diagnostic tests. Objective To assess the analytical and clinical …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused a pandemic.
Diagnostic testing for SARS-CoV-2 has continuously been challenged due to several …

A key goal of SARS-CoV-2 surveillance is to rapidly identify viral variants with mutations that
reduce neutralization by polyclonal antibodies elicited by vaccination or infection …

Population testing remains central to COVID-19 control and surveillance, with countries
increasingly using antigen tests rather than molecular tests. Here we describe a SARS-CoV …

Background Evolutionary pressure has led to the emergence of SARS-CoV-2 variants, with

Background The role of host immunity in emergence of evasive SARS-CoV-2 Spike
mutations under therapeutic monoclonal antibody (mAb) pressure remains to be explored …

SARS-CoV-2 variants have evolved a variety of critical mutations, leading to antigenicity
changes and immune escape. The recent emerging SARS-CoV-2 Omicron variant attracted …
