You really need to take your son to the doctor. He doesn't just have diarrhea, he has other symptoms. Even if he did have only diarrhea, he would need to go to the doctor to find the cause. You can treat and "cure" the diarrhea, and still have a sick child. It could be any number of things, not just from a virus, but it's important to find it. Especially if he is not eating. Little children burn a lot of calories and need a lot of nutrition and fluids. If that is not enough, diarrhea is the number 1 cause of death of children in developing countries. Please take your son to the doctor.
