Symptoms of a disease that is highly infectious
Measles is characterised by a high fever, cough, runny nose, red eyes (conjunctivitis) and a generalised red rash that starts on the head and then gradually moves down the patient's body. Anyone with measles is infectious from four days before to four days after the onset of the rash. Direct contact with a case is not needed for measles transmission to occur. Airborne transmission of the virus (which can be caused by an infected person coughing and sneezing) makes measles one of the most infectious viruses known to man.
