Doctor, My daughter born on September 2015. From her third month she suffered with fever. It's okay. In December 2016, she had fever and doctor said that problem is blood infection i.e white blood cells increased. For that 7 days treatment is done in hospital. Then for every month she is getting fever. On June 2018, again suffered with fever and doctor said that it was blood infection again stayed in hospital for 7 days. After that now she was getting fever for every 15 days. It's creating tension to us doctor. First blood infection problem is white blood cells count increased to 12000 only. Second time blood infection problem is white blood cells count increased to 20000. As a parent, our observations are 1. When she was eating non-vegetarian 2.When was exposure to sun 3. When climate change suddenly from Cold to hot and from hot to cold. Kindly give reply for our tension that our daughter getting fever for every 15 days. Now also having fever due to shifted to other place.
