Measles

Masern

Measles can occur at any age, sometimes causing very serious complications. Two doses of MMR vaccine provide life-long protection against the complications of measles, mumps and German measles. The aim is to eliminate measles from Switzerland.

Pathogen and transmission

Measles is an infectious disease caused by measles virus and dreaded for its often severe complications. The highly contagious measles virus is transmitted in droplets when people cough or sneeze.

Clinical picture

Measles usually develops in two phases. The first begins 7 to 18 days after infection with fever, tiredness, abdominal pain, sensitivity to light, inflammation of the mucous membrane in the mouth, and is often accompanied by coughing, a runny nose and a sore throat. The second stage follows two to four days after the start of the symptoms, with a burst of high fever. The existing symptoms worsen and only now a typical rash appears.

Uncomplicated cases may heal fairly rapidly without any defects. However, the following (and other) complications can occur: encephalitis (1 in 1,000 cases), measles pneumonia (10 to 60 in 1,000 cases) or middle-ear infections (otitis media). The complications of measles sometimes lead to death. There is no specific therapy for the disease. The treatment is limited to mitigation of symptoms.

Occurrence and frequency

Measles is not specifically a childhood disease. It can occur at any age. Before the vaccine was introduced, measles was a disease that practically all children worldwide developed. It has become far less common since vaccination was introduced and has been eliminated from many regions and continents, such as the whole of North and South America, with the exception of a few imported cases of measles.

Switzerland, by contrast, records about 50 cases annually, even in years when there is no epidemic. During an epidemic the figure can rise to well over 2,000. The mortality rate for measles is currently between 1 and 3 in every 10,000 cases in industrialised countries. In developing countries it is often 300 - 500 in every 10,000 cases and sometimes even higher.

Prevention

The Federal Office of Public Health recommends a combined vaccine against measles, rubella and mumps (MMR-vaccine). The main reason for vaccinating against these three diseases is to protect children and adults in Switzerland from their at times extremely serious complications. Two doses of an MMR-vaccine are recommended: the first at 9 months, the second at 12 months of age. A catch-up immunisation is possible at any age and is recommended for anyone born after 1963 who is not yet immune. Risk check measles.

The vaccine is efficacious, safe and well tolerated. Protection is usually life-long in people who have been fully vaccinated (i.e. with 2 doses). The World Health Organization (WHO) and its member states are working together to eliminate measles from Europe by attaining a sufficient vaccine coverage among infants.
