  • Antibody-dependent enhancement (ADE), sometimes less precisely called immune enhancement or disease enhancement, is a phenomenon in which the binding of a virus to non-neutralizing antibodies enhances its entry into host cells, and sometimes also its replication.
  • This phenomenon—which leads to both increased infectivity and virulence—has been observed with mosquito-borne flaviviruses such as Dengue virus, Yellow fever virus and Zika virus, with HIV, and with coronaviruses.
