I got roseola infantum.

The roseola infantum, also called as "sixth disease" or "three day fever", is a disease caused by two human herpesviruses, HHV-6(Human Herpesvirus Six) and HHV-7, also called Roseolovirus. Simple explanation, it caused by virus. Let talk about symptom, it begins with sudden high fever. After a few days the fever gone, the patient appears to be recovering. Everything looks seem back to normal but a few hours later a red rash appears. And it will disappear after a few days.

So this is what I faced with today. A red spot all over my body, my face, my arm, and everywhere. It's not a dangerous disease. I will be back to normal in this few days. Don't worry everyone.
