Measles is highly contagious and can spread through coughing or sneezing.
Symptoms include fever, a cough, a blocked nose and a rash. Possible complications include meningitis.
One of the most effective ways of preventing the disease is a measles vaccine.
The World Health Organisation believes that a resurgence of measles worldwide is caused by the growth of an “anti-vax” movement and the spread of false information about vaccinations being dangerous.
