I work in an Engineering office w/120+ people of different nationalities. Around mid Jan., one of the guys came down w/ a sickness that had many of the current virus symptoms, then over the course of the next month it went thru 8 out of 12 in the immediate area, myself being 5 wks removed. Never seen something rip thru the office that quick, as others where affected in other parts of the bldg. Non where tested as there where no COVID-19 tests being done. Did we have it? Will never know unless the blood test for anti-bodies is done, which I read somewhere may be instituted to see how widespread immunity is.
