It does seem that your younger son has an allergic reaction known as urticaria. Give him an antihistamine syrup called Allecet 5ml once daily until the rash has cleared up.Also apply calamine lotion to his rash twice daily. Rather use the Peaceful Sleep pads in the special plug-in unit in his room and do not apply any mosquito repellant to his body directly.
Your older son appears to have a viral infection as he is not responding to the antibiotic. You still should complete the course. He may have a viral tonsillitis which often takes about 10 days to clear up.If he is still feverish by Tuesday 4 December take him back to the doctor for a check up.
