I’m not a doctor, but based on this remark in the Live Science article about the relatively few children who’re victims of the Corona virus I will hazard a guess that extends what it says in this remark.
The innate immune system is the first line of defense against pathogens. Cells in that system respond immediately to foreign invaders. (The adaptive immune system, by contrast, learns to recognize specific pathogens, but takes longer to join the battle.) If the innate immune response is stronger in children exposed to 2019 nCoV, they may fight off infection more readily than adults, suffering only mild symptoms.
It seems sensible to assume that the innate immune system protecting a child’s lungs must be more effective than that in adults. Their breathing passages are shorter and their adaptive immune system has yet to learn what pathogens to fight. That stronger innate immune response (attacking anything foreign) may give them added protection against a virus like the Corona.
One peculiarity of the Corona virus is that its infection must plant itself well inside our lungs. Throat swabs often fail to detect it. That contrasts with many other viral infections that first settle in our throats and then move to our lungs. A throat infection is uncomfortable but not deadly and gives our adaptive immune system to prepare to fight it before it reaches our lungs, where it can be lethal. Because the Corona virus bypasses our throat and infects our lungs directly, the response of our adaptive immune system is delayed.
Of course, there’s also another factor suggested by the article, that the immune system of adults overreacts to a Corona virus infection, making matters worse.
Adults are also more susceptible to a detrimental immune response that causes a condition called acute respiratory distress syndrome (ARDS), said Dr. James Cherry, a professor of pediatrics and infectious diseases at UCLA’s Geffen School of Medicine. A complicated imbalance of immune cell activity sends inflammation into the lungs into overdrive, ultimately causing fluid to fill the alveoli, or air sacs, according to research published in the journal Annals of Translational Medicine
ARDS is the primary way that the Corona kills.

Also consider Antibod-Dependent -Enhancement, which I found explained on another post from ZeroHedge (I know, I know) and which I posted here:

Adults (particularly Asian men!) are also more likely to smoke.
Maybe it is a manufactured virus from a biolab? Maybe it was part of China’s plan to take over countries by targeting their military members who are mostly male. Pure speculation on my part but who knows what this is exactly?
