Thanks nickeyandalan & motherofhighspiritedones, my younger one now is on the road to recovery he seems better, the elder one have slightly bad condition than his brother but not to bad so long he's eating I'm not so worried however today we received a bad news.
One child from my younger boy's school passed away last evening due to the same disease he had a high fever and was throwing up. Yesterday the people from Ministry of Health came to my house to take some samples from my boys, the ministry ordered my younger boy school to close for 10 days and today which is supposed to be the eve of our country's independent day, children from that school aren't allowed to celebrate as precautionary measure have to be taken hope all these will be over soon.
