Abstract

Highlights: Few studies are available about persistence of SARS-CoV-2 antibodies from LMICs. Anti-nucleocapsid antibodies waned over a 7 month period post SARS-CoV-2 infection. Anti S1-RBD antibodies were relatively stable. Neutralizing antibodies were persistent up to seven months post-infection.
