Antibody-dependent enhancement effect as a potential threat induced by COVID-19

At present, Corona virus disease 2019(COVID-19) has become a major concern all over the world and leads to huge medical pressure. Antibody-dependent enhancement (ADE) of viral infection has been researched extensively in many viruses. It is not yet clear whether SARS-CoV-2 infection causes ADE effects. However, there is evidence that ADE may be found in COVID-19. We have discussed the possibilities of ADE effect induced by COVID-19 and proposed a series of measures to deal with it.
