Suggest Treatment For Low Grade Fever, Lethargy And Loss Of Appetite

Respiratory tract infection
Detailed Answer:
Good afternoon.
Thanks for asking on HealthcareMagic.
I am sorry to hear that your 2 year old son is not doing well. Most of such episodes are caused due to viral infections. The low grade fever could be due to an infection which is causing the lethargy and loss of appetite. Probably the mucus and the gag reflex made him throw up. The yellow phlegm could indicate a superadded bacterial infection on a viral infection.
If I was the treating physician, I would have liked to listen carefully to the chest of the child to check if my suspicion corroborates with the findings. A complete blood count would have made things clearer.
I would insist you to get a blood count done and to visit your doctor with the report.
Wishing your son to get well soon.
Regards
