Measles is a highly contagious viral illness characterized by a fever, cough, conjunctivitis (redness and irritation in membranes of the eyes), and spreading rash.
Causes, incidence, and risk factors
Measles is caused by a virus. The infection is spread by contact with droplets from the nose, mouth, or throat of an infected person. The incubation period is 8 to 12 days before symptoms generally appear.
Immunity to the disease occurs after vaccination or active infection.
Before widespread immunization, measles was so common during childhood that the majority of the population had been infected by age 20. Measles cases dropped over the last several decades to virtually none in the U.S. and Canada because of widespread immunization, but rates have crept up again recently.
Some parents are refusing to have their children vaccinated because of fears that the MMR vaccine, which protects against Measles, Mumps, and Rubella, can cause autism.
Large studies of thousands of children have found no connection between this vaccine and the development of autism, however, lower vaccination rates can cause outbreaks of measles, mumps, and rubella — which can be serious.
tiny white spots inside the mouth (called Koplik’s spots)
photophobia (light sensitivity)
appears around the fifth day of the disease
may last 4 to 7 days
usually starts on the head and spreads to other areas, progressing downward
maculopapular rash — appears as both macules (flat, discolored areas) and papules (solid, red, elevated areas) that later merge together (confluent)
itching of the rash
Note: The period between the appearance of the earliest symptoms and the appearance of a rash or fever is usually 3 to 5 days.
Signs and tests
viral culture (rarely done)
a measles serology
There is no specific treatment of measles, though some children may require supplementation with Vitamin A. Symptoms may be relieved with bed rest, acetaminophen, and humidified air.
