Welcome and thanks for posting your query on HCM.
After reading your query I can make out that your son has impetigo
lesions all over body and these scabs are increasing day by day.
Impetigo is a simple bacterial infection caused by bacteria. The skin gets infected and leads to formation of honey crust colored lesions which are known as scab. One lesion is the source of infection and leads to further more spread of multiple other lesion wherever the fluid comes in contact.
For the betterment I request you to give a course of proper good antibiotic to your son under medical advice
. You can go for culture and sensitivity of the affected area to know the exact sensitivity of the antibiotics.
Maintain good hygiene of your son and ask him to touch or scratch any area.
Do not worry your son will be totally alright.
Wish your family good health.
