Abstract
Severe acute respiratory syndrome coronavirus-2 (SARS CoV-2) variants poses major threats in increasing infectivity, transmission, mortality of Coronavirus Disease 2019 (Covid-19). Additionally, SARS CoV-2 variants resist antibody neutralizations or may abolish vaccine efficacies. Researches to develop economical and fast methods will support the developing or poor countries to challenge the Covid-19 pandemic via tracking common mutations that may help to deploy the vaccination programs and control the virus. Current study has developed a novel low-cost rapid technique, exploiting real time PCR probes and conventional PCR specific primers, to identify N501Y mutation, which was independently emerged in the UK, South African and Brazilian variants. Currently, these variants tend to spread to all over the world and seem to be more infectious, transmissible and fatal. This study helps tracking the N501Y mutation for understanding its clinical and epidemiological characteristics, in those countries where sequencing facilities are lacking or expensive. Further study should focus on other common mutations in the variants of concerns of SARS CoV-2.Keywords
