Hai. thank you for trusting HealthCareMagic. I m dr. Asti. your son s platelet count is on normal range (150.000 - 400.000 mm3). so far there s no need to worry about the result. but you have to be aware for the other symptoms​ which may come. the fever which is too high can trigger seizure. you should keep the temperature on the normal range by giving paracetamol with the doses as prescribed by your pediatrician. if the fever still happen, you can give paracetamol every 4 hours, but not exceed 5 doses in 24 hours. you should concern for another sign symptom for bleeding sign to exclude the possibility of dengue fever. allerkid is a good choice for sneezing. it contains Cetirizine that works as systemic antihistamine and has good effect on respiratory track for children. high temperature of fever can show us the cause of viral. it can happen because our immune is weak. so you must maintain your son immunity. give your son such kind of food whatever he likes. rehydrate him as much as he wants, especially give him warm water. give nutritious food, juice and veggies as vitamin C is good for healing. give warm soup to increase his appetite. if he still breastfeeds, continue breastfeeding him. you can recheck the lab if the fever still happen after 4 days, and re-evaluation can be done on 7 days post fever. I suggest you to consult to your pediatrician about that, if the symptoms still present. I hope these can be helpful for you and your son can get well very soon. regards, dr. Asti
