In this study people who came into contact including family and hospital staff, none were shown to have been infected. 25% of the group had presxsisting Cardiovascular disease. A few of them got a cough during this time but none seemed to get COVID19.
“The blood counts in most contacts were within a normal range. All CT images showed no sign of COVID-19 infection. No severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections was detected in 455 contacts by nucleic acid test“.
“Conclusion: In summary, all the 455 contacts were excluded from SARS-CoV-2 infection and we conclude that the infectivity of some asymptomatic SARS-CoV-2 carriers might be weak.”
This coupled with the fact that we now know COVID19 doesn’t stay of surfaces or spread that way means this whole thing was completely blown out of proportion.
