I do agree pax are afraid regardless, too may years of "germ-ridden cabin air" narrative (while the real problem all along was high-touch surfaces, which I think most of us learned the hard way long ago).

It was always believed that this was due to the size of the infecting inoculum. The smaller the initial dose, the longer the person’s own immune system had to come up to speed to fight the infection.
it was the same way with COVID-19s elder brother SARS which disproportionately hit healthcare workers whose disease courses were shorter (and more lethal) than community acquired infection.

Because the case occurred prior to Information about symptoms or mitigation protocol being widely known (early February) this couple did NOT practice any quarantine, isolation, or social distancing.

Routine environmental exposure for those maintaining the most basic and modest social distancing appears very low. The hotspots almost invariably are coming out of parties, bars, etc (to say nothing of covid parties
). No community hotspots that I've heard of are related to air travel, and I've been paying attention to that.
Masks can clearly reduce anything the wearer might be emitting, and might even minimize exposure from another person.

Some have postulated this is why it spreads so thoroughly in nursing homes. Masks don't help here but washing hands does but only with soap and water, not sanitizer.

My GUESS (and it is only that) is that the apparently non infected one had t-cell immunity from either earlier exposure to COVID -19 or to one of the other four human coronaviruses that have been recognized for years/decades as being causative agents for the common cold.

Cross-reactivity and cross-protectivity may be 2 sides of the
same coin in COVID-19, too. SARS-CoV-2 is closely related to
human coronavirus OC43 (another betacoronavirus), the most
prevalent seasonal coronavirus detected among patients younger

It is apparent from some of the European and Chinese studies that some people clear the humoral antibodies (mostly IgG) from their bloodstream fairly quickly, especially in mild cases, but retain functional immunity through the T-cell And IgA systems. Then again, there are a lot of hastily produced antibody tests out there that may just plain miss low levels of antibodies.
At the same time, current IgG-dependent serologic screening may not be useful because of the rapid fall in IgG levels to undetectable levels in mild cases, and the IgA production in asymptomatic infection may lead to these being missed in screening. The result is a large underestimation of actual infections
