What Causes Measles ?
Measles is caused by infection with the rubeola virus. The virus lives in the mucus of the nose and throat of an infected child or adult.
The disease is contagious for 4 days before the rash appears, and it continues to be contagious for about 4 to 5 days after.
Infection spreads through:
Physical contact with an infected person
Being near infected people if they cough or sneeze
Touching a surface that has infected droplets of mucus and then putting fingers into the mouth, or rubbing the nose or eyes
The virus remains active on an object for 2 hours.
Who is at risk for measles?
Measles primarily occurs in unvaccinated children. Some parents choose not to vaccinate their children for fear that vaccines will have adverse effects on their children. Most children and adults who receive a measles vaccine do not experience side effects.
Some parents believe that the measles vaccine can cause autism in children. However, numerous studies have proven that there is no link between autism and immunizations.
A vitamin A deficiency is also a risk factor for measles. Children with too little vitamin A in their diets have a higher risk of catching the virus.
