Longevity of seropositivity and neutralizing titers among SARS-CoV-2 infected individuals after 4 months from baseline: a population-based study in the province of Trento	2020-11-13		.txt	text/plain	3142	212	55	All individuals above ten years of age resident in 5 municipalities of the Autonomous Province of Trento, northern Italy, who resulted IgG positive for anti-SARS-CoV-2 nucleocapsid (NC) antibodies in a serosurvey conducted on May 2020 were retested after 4 months. The duration of protection against infection with common human coronaviruses appears to be rather short 2, 3 , and there are studies showing declines in IgG antibodies against SARS-CoV-2 among both symptomatic and asymptomatic individuals 4, 5 . In order to evaluate the persistence of SARS-CoV-2 antibodies, we repeated a serosurvey in five municipalities of the Autonomous Province (AP) of Trento, Italy, recruiting those individuals who had resulted positive in a large population-based seroprevalence study conducted 4 months before 14 . The analyser automatically calculates SARS-CoV-2 NC IgG antibody concentration expressed as an is the author/funder, who has granted medRxiv a license to display the preprint in (which was not certified by peer review) preprint	./cache/cord-290796-x9xqqcj6.txt	./txt/cord-290796-x9xqqcj6.txt
