Explore the causes and appropriate treatment methods for a 5-month-old baby having low platelet count after fever.

Lately, I’ve been experiencing some dizziness and a pale complexion. A few days ago, I went to the hospital for a routine blood test, and the doctor said my platelet count is a bit low. What should I do about low platelet count?

My son is 12 years old. About half a month ago, he had a cold with coughing and asthma. He received intravenous injections for 4 days but has not recovered yet; he still has coughing and phlegm. Yesterday, a blood test showed that his platelet count is low, only 90, and his hemoglobin level is 11.0, with all other indicators normal. What should the expert do?
