Siti : "Hi Dayu, have you taken any medicine, yet?"
Dayu : "Yes, I have. But it only helps a little"
Siti : "Maybe you just have to take some rest in order to get well soon."
Dayu : "You are right. In fact, I have been to the toilet many times today."
Edo : "Poor you. You need to drink a lot of water so that you will not get dehydrated."
Dayu : "This is a good lesson for me. I never care about what I eat."
Udin : "Right. Guys, don't forget to wash your fruits and vegetables before you eat them so you will not take any germs into your tummy."
Dayu : "Yes, Boss. You are right. We should always clean our food well. I should be more careful now."
Lina: "Dayu, you look very pale. I think you need to see the doctor soon in order to get help. Don't take diarrhea lightly."
Dayu : “No, of course not. Actually, My mom is on her way from the office to take me to the hospital."
Siti : "Good. We'll help you to get ready now."
What is Dayu's condition?
