<s>[INST] my 3yr old son has been having temperature n since 2days he had antibiotic injection inspite of that the fever keeps coming n also he is passing green colour motion 6-7 every day since three days he is having chills before fever pls help regarding what it could be. he is 15 kg [/INST] fever and diarrhoea are sings of gastroenteritis which is an infection of the intestine usually caused by a virus and doesn't warrant antibiotic therapy .6-7 motions a day can cause dehydration . you can observe that by noticing that he is getting thirsty, decreased urination and dry skin and lips .hydration and fluid managment is very important in this case , you can give ORS , give 900 ml in the first 4 -6hours to overcome the deficit . you can give SMECTA sachets which helps in decreasing the amount of diarrhoea for a couple of days .I hope this helps </s>
