Researchers have identified two types, with the virus different for either of them. While both involve developing a rash and a high fever, these are two distinct diseases. The first one is what the majority refers to when it refers to it by the word ‘measles. Rubeola is known as ‘red or hard measles’. However, the most common terminology is just ‘measles’. While more than half the population suffering from measles recovers from it, rubeola could also cause ear infection or brain inflammation or even pneumonia. Rubella is also known as ‘German measles’ and/or ‘3-day measles’ and is a less severe type than rubeola. Nevertheless, it too could prove fatal if a pregnant woman who has the virus transmits it to the child that is still unborn.
