Question
My child often gets colds and fevers. This morning, when I put him to bed, I noticed his head felt hot. When I took his temperature, it was 37.8 degrees Celsius. His eyes are a bit red, but he doesn’t have a runny nose or cough. He’s also crying a bit. He was fine before taking his afternoon nap last night. I need assistance with how to handle this situation: What could be the reason for my son’s sudden high fever, could it have started to fever early this morning?
Answer
Generally speaking, most fevers are caused by infections, with pathogens including bacteria, viruses, and mycoplasma, with the latter two being the most common. You should consult a doctor to investigate the cause of the high fever and pay attention to the throat condition, as respiratory infections are a major cause of fever in infants and young children. At the same time, perform a complete blood count examination carefully to confirm whether it is a viral or bacterial infection. Provide additional symptomatic anti-inflammatory and antiviral medication.
