Measles is an illness caused by infection with the measles virus. Early in the infection, symptoms may include fever, tiredness, cough, sore throat, runny nose, sore eyes and photophobia. These symptoms usually worsen over three to five days, then a blotchy rash begins on the head and over the next day or two spreads down the entire body. The rash lasts four to seven days. Measles illness usually lasts about 10 days. The cough may be the last symptom to disappear.
Measles is often a severe disease, frequently followed by middle ear infection (7% of cases) or bacterial pneumonia (6% of cases). In as many as one in every 1000 cases, encephalitis occurs, often resulting in death or permanent brain damage. Sometimes brain damage may not appear until many years later. Complications from measles are more common and more severe in the chronically ill and in very young children.
The incubation period is about 10 days (range 7 to 18 days) to the onset of prodromal symptoms and about 14 days to the appearance of the rash.
The infectious period is from 24 hours prior to the onset of the prodrome to four days after the appearance of the rash. If the prodrome is poorly defined, the infectious period is considered to commence four days before the appearance of the rash.
Measles is a highly contagious viral infection transmitted via respiratory aerosols which remain a risk to others for up to 30 minutes after the person has left the area.
Measles is spread by breathing infected airborne droplets caused by coughing and sneezing, and by contact with hands, tissues and other articles soiled by nose and throat discharges.
The diagnosis is suspected from clinical examination and is best confirmed by detection of the virus (by PCR) in urine, throat, blood or eye specimens; or alternatively by serology.
Additionally, if not taking pathology specimens at your rooms, inform the pathology collection centre prior to sending in a potentially infectious case, or use the SA Pathology home visiting service.
A person who is not immune suppressed is likely immune to measles if:
Measles is best prevented by receipt of two doses of measles containing vaccine. For further details see:
