cord-314734-ai0hz4uq	Hung, Ivan Fan-Ngai	SARS-CoV-2 shedding and seroconversion among passengers quarantined after disembarking a cruise ship: a case series	2020-06-12		.txt	text/plain	4595	248	56	Thus, the Diamond Princess cruise ship, which was quarantined because of an onboard outbreak of COVID-19 in February, 2020, provides an opportunity to define the shedding pattern of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and patient antibody responses before and after the onset of symptoms. Participants were prospectively screened by quantitative RT-PCR (RT-qPCR) of nasopharyngeal and throat swabs, and serum IgG and IgM against internal nucleoprotein and the surface spike receptor-binding protein (RBD) of SARS-CoV-2 at baseline (upon entering quarantine) and on days 4, 8, and 12 of quarantine. Evidence before this study We searched PubMed on March 14, 2020, with no date restrictions, for articles in English, using the terms "Covid-19", "coronavirus", "antibody", "viral load", "cruise ship", "quarantine", "shedding", and "seroconversion". By Feb 20, 2020, 76 passengers from Hong Kong were hospitalised in Japan after testing positive for SARS-CoV-2 by throat swab RT-PCR, of whom two individuals died from complications of the infection (appendix).	./cache/cord-314734-ai0hz4uq.txt	./txt/cord-314734-ai0hz4uq.txt
