Hi there. Thank you for your question. I will be helping you out with your queries
since how long in total is he having these symptoms?
Have the symptoms improved any? or no improvement whatsoever?
The oral blisters that he is having means that he is most likely either having an infection with cocksackie virus or with HSV type 1 virus.
When you took him to the doctor did he having blisters then?
I think that you should give ibuprofen 8 hourly and tylenol syrup 6 hourly, both.
Plus if his symptoms does not improve in the next day or two or his condition deteriorates I would again take him to the ER
I think that with these symptoms I would have him examined today
just to make sure that he is okay
Sometimes these viruses can cause one to have inflammation of the meninges of the brain
which can cause one to be lethargic
so I would want that to be ruled out as well
Plus for the fever I would give tylenol as well along with ibuprofen
viral infections can take up to a couple of weeks to go away completely
Antivirals are of no help in these viruses
Antivirals are only given when there is infection of the brain with the viruses or genital involvement or serious infection
Usually 10-14 days
It should go away in up to two weeks time
in the next few days symptoms should start settling
The doctor should give a leave from school certificate or a paper
Infection can be transmitted to other children so cannot go to school now, plus he is also not fit for school with the high fever
Being lethargic is common with a viral infection
Most likely its not meningitis
But just to be dead sure I would just want him to be examined
You are most welcome
Hope he gets well soon
