Why do asymptomatic COVID-19 cases even happen?

The facts of COVID-19 include this disturbing reality: We have little idea who among us is spreading the disease.

 

Up to half of stealthy spreaders “feel fine” on Saturday night—but by the time they come down with the telltale cough, fever, and fatigue on Monday, they’ve potentially infected multitudes. Meanwhile, what could be an even more elusive bunch—people who are infected with the coronavirus but never, ever feel sick—make up 40 percent of infections in the United States, according to estimates from the Centers for Disease Control and Prevention.

 

What’s especially puzzling is why these two groups—presymptomatic transmitters and asymptomatic cases—appear so frequently. Other viruses, such as influenza and colds, spread silently too. But the extreme evasiveness of COVID-19 makes it harder to control.

Boy, have you come to the right place to ask that question, I think there are a least 15 Biochemists and 6 Infectious Disease experts in this forum! I'm sure a few will be along soon to give you a full breakdown! 

The scary thing is that 50% of asymptomatic people have abnormalities to their heart, lung or brain. And we don't know how long it will last.  So, you really don't what to get this virus and herd immunity is not an option.

How do they spread it, I mean if they aren't sick, don't cough, sneeze, etc, etc, etc, maybe it's in the water ????

 

the carrier of the virus is foul air,

within science community commonly known as miasma.

asians and other groups trading with asia like europeans and arabs

has since the days of the great genghis khan been exposed to foul air

propagating through the silk road, and thusly has evolved herd immunity

by a hardened immune system, but some individuals within the herd arent up to snuff

They expel air with micro droplets of moisture laden with the virus by breathing and talking. In a closed space, these droplets remain suspended in the air for hours and are inhaled by other persons. Result: so-called "super spreading"

So a bit like sleeping with a floozie with no protection, however can be more lethal. What ever happen to the good old days ?

Yes, a complete mystery,

It's almost as if Chinese agents with weaponized aerosol cans of COVID are wandering around, a puff here, and a puff there.

Don't rule anything out ^

You have to distinguish between the truly asymptomatic majority, and those who are at the first stage of the illness.  Scientists are still whistling in the dark imo.
