Hi migizii,
Men can and are more restless then women. Viruses/illness know no boundary.
I don’t know what it takes for people to get SCARED STRAIGHT. Maybe if somebody your husband knows becomes ill, he will have a change in attitude.
About all you can do, is keep surfaces clean. Do not forget door knobs, light switches anything that is handled by more then one person, that includes refrigerator handles.
By the way what country are you in? England??
