Baby refusing to eat after viral fever.

Hi doctors, It has been 3 days since viral fever of 2 year old has subsided. He was treated with basic cold and cough medicine (levocit and ascoril ls and ibugesic plus as fever has crossed 102). Fever stayed for 4 days. Since last Tuesday he did not eat much solids other than 1 biscuit or 2 per day... A wafer ... No proper solid diet taken. He is refusing ors, juices, and anything I'm trying to feed him... He is not letting anything close to his mouth... He is crying a lot and clingy to us all the time ... Now at present his body is very cold to touch . He is taking milk 125 ml 3 4 times a day and nothing more than that. He has sweet tooth, but now not eating anything. I'm getting worried and kindly suggest what can be done . Before viral fever he was never like this
