Measles is an incredibly infectious viral illness which can have serious complications for children and adults. In this article we will cover the causes, symptoms, treatment, and prevention of measles.
Measles begins with a viral infection of the upper respiratory tract (nose and throat) and will eventually spread to other parts of the body. The initial symptoms of measles include fever, runny nose, coughing, sneezing, sore and watery pink eyes. From three to seven days after the first symptoms as the virus spreads throughout the body, infected people will develop a blotchy rash beginning on the head and spreading to other parts of the body.
Measles is a highly contagious virus which spreads easily through the air in infected droplets which are a by-product of an infected person sneezing or coughing. The virus can stay in the air for two hours after an infected person has left the area. It can also be spread on contact with surfaces that have been contaminated with an infected person’s snot or saliva. The virus can survive on surfaces for up to two hours. An unvaccinated person who is exposed to the measles virus has up to a 90% chance of becoming infected. One person with measles can spread the disease on to 12-18 people who are not immune.
Immunisation has been the primary way to prevent measles in New Zealand since 1969. The vaccine available today is called the measles, mumps, and rubella (MMR) vaccine. For the vaccine to be effective two doses are required, providing 99% protection against measles. It is a free vaccine and is part of the childhood immunization schedule for children at 12 and 15 months of age. If you are unsure if you have been vaccinated against measles, you are recommended to get vaccinated. It’s safe to get an extra dose.
Adults born before 1969 are considered immune to measles.
If you suspect you may have measles or have been exposed to measles, contact a healthcare professional. While measles doesn’t have a specific treatment your doctor will likely recommend you get rest and some options for symptom relief. This may include:
If you are not immune and exposed to the virus a measles vaccine, given within 72 hours of exposure may provide protection, or lessen the severity of an infection. This may help to limit the spread of the virus as well.
Most people will recover from measles after 7 to 12 days. However complications can occur. In the 2019 outbreak in New Zealand, over 30% of people infected with measles were admitted to hospital. These complications can include:
Encephalitis occurs in around 1 in 1000 measles cases.
