Persistence of anti-SARS-CoV-2 antibodies in non-hospitalized COVID-19 convalescent health care workers	2020-08-01		.txt	text/plain	3283	188	47	Sera from healthcare workers affected by non-severe COVID-19 were longitudinally collected over four weeks, and compared to sera from patients hospitalized in Intensive Care Units (ICU) and SARS-CoV-2-negative subjects for the presence of IgM, IgG and IgA antibodies as well as soluble pro-inflammatory mediators in the sera. The performances of these ELISA assays were assessed for the different viral antigens and classes of antibodies by determining ROC curves using i) a cohort of 56 sera from COVID-19 patients collected between April and June 2020 and tested positive for nasopharyngeal swabs, and ii) 436 pre-COVID-19 sera, collected between 2012 and 2015 (Supplementary Table 1 and Figure S1 ). Non-hospitalized COVID-19 subjects manifested a lower antibody titer as compared to severe ICU patients for all the tested antibody classes and viral antigens ( Figure 1B-D) .	./cache/cord-299783-8ti6r0eh.txt	./txt/cord-299783-8ti6r0eh.txt
