Все дело в слюне, которую комар выделяет в процессе питья крови. Организм человека распознает ее как инородное вещество и начинает производить антитела для ее устранения. Поэтому в месте укуса усиливается кровоток. Если чесаться, очень быстро возникает рана от расчесывания, на месте которой ощущается не только зуд, но и боль, свидетельствующая о начале воспаления, вот почему комариные укусы чешутся ещё сильнее.
