A good way to tell the difference between measles and roseola is to notice where the rash appears and what it looks like.
Measles is a condition that both children and adults get and produces a splotchy reddish rash that spreads from head to foot.
Roseola on the other hand is most common in children 2 years old and younger but sometimes adults can get it as well.
Roseola also causes a rash to form on the trunk, which spreads to the upper arms and neck and fades within days.
Roseola is not a form of measles.
Although roseola and measles seem and look similar the two are very different from each other.
Roseola mostly affects toddlers and infants while measles affects children above 2 years old and even adults.
