Rubella, rubeola, and roseola are common communicable diseases caused by viral infection.
Communicable diseases are the type of diseases that spread from one person to another through the means of contact, air, or any vector. It can be chronic or acute.
All the above three diseases are infectious diseases that spread through contact or any other communication and are caused by a virus called Herpes virus. Their common symptoms include fever and rashes that appear primarily on the face and then spread down to the whole body.
Roseola and rubeola are more likely to occur in children while rubella is more likely to occur in adults. They do not have severe symptoms and go away on their own with some mild medications and proper rest. They are often treated by the MMR (measles-mumps-rubella) vaccine which is given to children right in their early ages of life about 12 to 15 months of age. If it persists, try to reach a doctor or take acetaminophen (Tylenol) on his advice.
