Genetic ‘shield’ may explain asymptomatic COVID-19 cases, scientists say
Melbourne researchers co-author a paper showing a genetic link for those who are infected but have no symptoms.
Australian and US researchers have discovered a genetic link that may explain why some people remain asymptomatic after SARS-CoV-2 infection.
The research shows a person who carries one copy of the protective HLA-B15 gene is twice as likely to remain asymptomatic after infection with SARS-CoV-2.
