@PaulRoundy1 No, Paul. I see that the neurologic complications in children is becoming more prevalent since last year (i.e., after the appearance of the Omicron strain). @PaulRoundy1 FYI, in Japan, among the officially reported COVID deaths of children from Jan. to Sep., 2022, the major endogenous cause was central nervous system symptoms (19/50; 38%), which is much higher than circulatory (18%) & respiratory (8%) ones.

3) the lack of coordination among countries regarding suppression strategies;
