I know a guy that tested positive, he still went to work and hung out with hundreds of people and no one else caught anything from him......
There are various types of Corona virus testing kits, unfortunately the most common is looking at an anti-body to the Corona virus, which is often either delayed or is seen post infection. The antibody testing kits are also quite variable in their results. The PCR testing is much more specific, but results can take days if not weeks to come back, there is also antigen testing kits. One needs to factor in the amount of viral load present in an individual that factors into transmission, i.e. there needs to be a high enough level and volume (route) to transmit the virus, virus load peaks early on in the infection process and will subside as one mounts an antibody response. I saw this with HIV when I treated patients, those that were treated with low or undetectable levels of virus had lower risk of infecting others. It is not uncommon for one to test positive to the Corona virus and be completely asymptomatic, but it also reflects that the individual's immune system responded to the virus and that viral loads were low. There are many factors involved in the transmission and outcomes, but this is not a seasonal event, and the effectiveness of the vaccines are unknown and at this point unproven as to their effectiveness. I still consult for a few of the companies involved in these vaccine developments/clinical trials. Will I get the Corona vaccine when it becomes available, most likely yes, but I do not take annual flu shots because I had paralysis from it in the past.
To say that out of 100's of people no one caught the virus, is suspect if there was no contact tracing and 2-3 week follow-up on all those individuals. There are very well documented cases of either a single individual or an event/celebration with mass transmission and often fatal outcomes. The issue is it is a bit like Russian roulette and the odds that one may have a lethal outcome increase with inter-current health issues and age. Other countries that have imposed strict measures to contain the virus such as Hong Kong, have had very low levels of transmission while maintaining a functional economy. My wife has family in HK and Macau, one of which is a medical doctor there.
