Measles Infection in Humans Definition Causes and Control

Measles is a highly contagious respiratory infection. It is also known as rubella or red measles. Measles are caused by virus measles hence the name of the disease. Mostly children below  5 years of age are infected through measles hence vaccination should be mandatorily given to children. Major epidemics occurred every 2-3 years causing 2.6 million deaths every year, before the introduction of the measles vaccine. The vaccine was invented in 1963. Severe measles occurs among poorly nourished young children who have insufficient vitamin A. Those whose immune system has been weakened due to HIV or AIDS or other diseases also get infected through measles easily.

Causes of Measles 

Measles spread through mucous and saliva of the infected person. The virus is released into the air when the measles infected person sneezes or coughs. Measles virus also travels through the air.

It spreads through:

• Respiratory droplets (coughing or sneezing)

• Saliva ( sharing drink or kissing)

• Touching contaminated surface.

• Skin to skin contact or close contact.

• In pregnancy from mother to baby, or nurse.

• Children below 5 years of age and adults older than 20 years of age may suffer from complications.

• Pregnant women can give birth to a premature child or low weighed baby if they didn’t get vaccinated by the MMR vaccine.

• People who got an infection of lungs such as pneumonia and encephalitis (swelling of the brain) can die.

• The most common cause of death in young children from measles is due to pneumonia.

• Out of every 1000 children who get infected with measles die from respiratory and neurologic complications.

• Long term complications may occur in people with measles infection.

•  Subacute sclerosing panencephalitis a very rare but fatal disease of the central nervous system which generally develops 7 to 10 years after a person has measles or either when a person seems to be fully recovered.

• During the resurgence in the United States from 1989 to 1991, 4 out of 11 every 100,000 were estimated to be at the risk of developing SSPE if they got infected due to measles.

• Children who get infected due to measles before 2 years of age are at a higher risk of developing SSPE.
