Vidcast:  https://youtu.be/PkD7gqdQnRI   Roughly half of those who test positive for CoVid virus are completely free of any disease symptoms,  A Chinese study just published in Nature Medicine compared clinical profiles and test results for 37 asymptomatic patients with 37 who were sickened by the virus.   Those asymptomatic shed measurable virus 72% longer than those with symptoms.  Around 82% of both asymptomatic and symptomatic COVID patients form IgG antibodies, but antibody levels of symptomatic patients were 6-fold higher than those of asymptomatic patients.   Asymptomatic CoVid carriers are potentially infectious longer than those obviously sickened by the virus.  Anti-viral antibodies seem not to be keeping those spewing virus healthy.  Other factors are at play.   https://www.nature.com/articles/s41591-020-0965-6   https://www.healthline.com/health-news/50-percent-of-people-with-covid19-not-aware-have-virus   #covid #asymptomatic #antibodies
