Hi and thanks for the query,
Clear running nose with no signs of alteration of his general health condition should be suggestive of a viral infection. Upper
respiratory tract infections in children are usually viral. It is however important to know why he is
vomiting. How is the nature of the vomiting? What are the possible drugs he has been taking lately? has the child been given his worm medicines regularly?
A few of these factors could lead to vomiting and usually ceases with time. However, if this persists a more detailed evaluation might be required. This could involve a
complete blood count and C reactive proteins to exclude a probable bacterial infection and urine analysis for
urinary tract infections, commonly expressing themselves as such in children. However, I think you need to be calm and watchful again for a few days. In case of anything setting in or persistence of the symptoms, consulting his
pediatrician for a complete review shall be the best thing to do.
Thanks and hope this helps,
Best regards,
Luchuo, MD.
