In their first study, published in the journal Science, researchers compared this set of genes in 659 patients with life-threatening COVID-19 to the same genes in 534 people with mild or asymptomatic COVID-19 [1]. This is the first clear . Most of SARS-CoV-2 infection are asymptomatic or mild cases, which is the main factor causing viral transmission. Asymptomatic COVID-19 patients from this cohort study were mostly young Bangladeshi, Filipino, and Myanmar workers from the dormitory outbreaks compared to majority of Chinese among symp- . Most studies on immune responses in COVID-19 have focused on moderately or severely symptomatic patients; however, little is known about the immune response in asymptomatic and re-detectable positive (RP) patients. Asymptomatic spread is the transmission of the virus by people who do not have symptoms and will never get symptoms from their infection. In the TIB MOLBIO SARS Coronavirus-2 kit, screening assay of the E gene and confirmatory assay of the RdRp gene were done. We've uncovered the first evidence of a genetic link that explains why some people who catch Covid-19 don't experience any symptoms.
