Measles

 

Clinical definition of the Measles test
Measles, also called as Rubeola or English Measles, is a highly contagious infection of the respiratory system caused by a virus. It causes flu-like symptoms along with a total-body skin rash. Measles is spread by contact with the fluids from an infected person's nose and mouth, either directly or through aerosol transmission. Measles or Rubeola is sometimes confused with rubella (German measles). Both the diseases are unrelated. There is no specific treatment for measles. The only way of preventing it is by administrating the MMRV [measles-mumps-rubella plus varicella (chicken-pox)] vaccine during childhood that would give immunity to the disease.
