First, only FOUR of the 15 children tested positive for C-19. That's just under 3/4 of that sample who had NO C-19 relationship at all.
The disease that caused the hospitalization was Kawasaki disease. It attacks people, primarily children, after a bout of viral illness - which can be a cold or other infection.
Second, I'm betting (and, as I seldom bet unless I'm 98% sure I'm right) that the children affected were of Asian descent - and, possibly, Afro-Jamaican, another group with the genetic variation that makes them susceptible to this disease.
It is NOT believed to be contagious. Prompt treatment is necessary, so don't take it lightly.
"For a very small percentage of children who develop coronary artery problems, Kawasaki disease can cause death, even with treatment."For MOST children, not a likely complication of ANY viral illness. For those with the genetic variation, can be serious. Fatalities are rare, although recovery can be several weeks.
Why is this surfacing now? Could it be because America is getting ready to get back to business as usual? Are the media TRYING to scare people into screaming for the Lockdown to continue?
What's the take-away? If you have Asian ancestors, you should become familiar with the symptoms. Prompt treatment is important, and highly related to good outcomes.
