Serologic testing revealed significantly lower concentrations of SARS-CoV-2 neutralizing IgM and IgA antibodies in survivors compared to non-survivors (p = 0.009).” These counterintuitive data again argue against SARS-CoV-2 being the sole driver of the rates of morbidity and mortality among COVID-19 patients and for additional factors that were not measured, such as the presence or absence of neutralizing IgM and IgA against bacterial or fungal coinfections. The gene discussed is CD40LG; the disease is COVID-19.
