We observed an increase in rotavirus-specific RV-IgA levels 28 days post-infection (convalescent phase) in almost all children with rotavirus-positive diarrhoea that had paired samples, Fig. 1B. Although the children with rotavirus-negative diarrhoea had detectable RV-IgA antibodies at the convalescent phase of infection, their GMC (95% CI) was not statistically different (p = 0.1094) from the levels detected at the acute phase of infection. Here, CD79A is linked to infection.
