Just wondering if this is normal as most people say children mildly affected. 9 year old son has temperature between 39 and 40 for 24 hours (bright positive lft), lethargic, aching, coughing and doing nothing but laying in bed. Def not dehydrated and is eating and drinking but looks poorly. Is this normal or should we be concerned? Giving neurofen and calpol regularly. Thanks!
