Unraveling the Mystery of Asymptomatic COVID-19: Researchers Discover Common Feature

A new study published in Nature suggests that "super dodgers," individuals who contract COVID-19 but never develop symptoms, may have a genetic advantage. These individuals are more than twice as likely to carry a specific gene variation that helps them destroy the SARS-CoV-2 virus. The mutation in the immune system-supporting human leukocyte antigen allows virus-killing cells, called T cells, to identify the coronavirus even if it is their first encounter. Understanding the biology behind asymptomatic infection has important implications for public health measures, vaccine design, and therapeutic development.
