Why does the baby of my home have a fever in the evening normally by day

The baby has fever during the day and at night. It is considered to be infectious fever. Due to low immunity at night, germs will stimulate the body temperature regulation center, causing the body temperature to rise, such as tuberculosis, tonsillitis, hepatitis, etc. This situation may also be caused by malignant diseases, such as leukemia, lymphoma, etc. Parents need to take their children to see a doctor in time to check the cause.
