My father and brother have been rigorously self isolating since last March (food brought in, my brother washes it down before putting it in the fridge, things like newspapers are left for 24 hours before being handled). The last time either went out was for my father's vaccination jab early in the month. (They might have had to collect a repaired car from a garage, though no direct human contact).
So how can they have caught a cold? Is the reproductive factor and transmission route just that much higher for colds? (Neither are particularly ill with it, just sneezing a bit).
Just as a thought, things bought in the house should be quarantined for either 48 or 72 hours, it might be something as simple as that. The newspaper thought remote, might be the culprit if it’s only left for 24 hours.
If I get anything in the post I disinfect the packaging. Depending on when it was sent I’ll clean if I can the contents with dettol. If it’s something like amazon everything gets cleaned and if I can’t clean it then it gets out in a bag and quarantined for 72 hours, shops I believe have to quarantine returns for 72 hours so I do the same.
Where is the newspaper kept? Just leaving it lying around might be enough for something to spread. collecting the car from the garage did they disinfect all the touchable bits inside and out before they got back in the car? As a driving instructor when we were allowed to work everything Thad to be disinfected, I even sprayed the seats and belts because it’s amazing what we touch with the hands,
Although no direct human contact there is very much the possibility of indirect contact with contaminated surfaces.
Did the car place disinfect everything inside the car if they touched anything, use masks inside the car and clean the body work such as handles etc. I’d say that was a very good chance of where they got it from,
It seems excessive but it’s amazing where you can pick things up from.
