Looks like infection, needs antibiotics.
Detailed Answer:
Hello Mr. XXXXXXX
Thanks for posting your query.
Please continue giving
ORS (oral rehydration solution).
Since
fever is present, there is high probability of bacterial infection, viral intestinal infections generally do not cause fever with loose stools.
If your son looks dehydrated, then you should take him to a nearby hospital where they have pediatricians, right now and admit him.
Your son will need a course of antibiotics like oflaxacin with
metronidazole for 5 days for the infection, this is prescription only medicine, hence you will need a prescription to get that.
Small children get dehydrated very fast, so if the stool number is more than 10 times, then it is highly recommended to take him to a hospital and admit him right away.
I hope this answers you question, please write back if you have any doubts.
Please continue giving ORS water, as much as he wants to drink.
Regards.
