I will let you in on a little secret...
you don't "catch" covid
you get "exposed" to a toxin or other form of poison from various types of weapons/devices including through means of tainted water/food supply, invisible methods like radiation/5g/DEW etc.
Once exposed, your human body by design (from our creator/God) goes into repair/heal mode and starts to attack and try and remove said toxin/poison by expelling it out of the human body, by means of coughing up phlegm, or a runny nose full of mucus,
sweating out toxins by inducing a fever, removing toxins by urination/bowel movements/vomiting.
This process can take days or weeks to complete until all toxins are removed and heal mode stops.
The fact that a family member or co-habitant gets sick at the same time or just after you, just means they were exposed to the same toxin in the same vicinity around the same time and their repair mode may kick in slightly quicker or longer than yours does.
So if your wife was "attacked" at work, then multiple employees including yourself may also go into repair mode if exposed to said weapon at the same time it happened to your wife.
Remember, you're not getting sick, your body is in heal mode. Let your body heal naturally, don't consume more chemicals (prescription drugs or fake vitamins) as this just hinders and prolongs the heal mode.
