One special identifying sign of measles is Koplik's spots. These are small, red, irregularly-shaped spots with blue-white centers found inside the mouth. Koplik's spots usually appear 1 to 2 days before the measles rash and may be noticed by a doctor looking for the cause of a child's fever and cough.
Measles can lead to many different complications: croup, bronchitis, bronchiolitis, pneumonia, conjunctivitis, myocarditis, hepatitis, and encephalitis. Measles can also make the body more susceptible to ear infections or pneumonias caused by bacteria. Symptoms and complications of measles are usually most severe in adults.
Description:
Measles is a respiratory infection caused by the measles virus. Before immunization was available, measles occurred in springtime epidemics, usually in cycles of 2 or 3 years.
Infants are generally protected from measles for 6 to 8 months after birth, due to immunity that was passed on from their mothers. Older children are usually immunized against measles according to state and school health regulations. Currently, outbreaks of measles are occurring most often on college campuses, among young persons who have either not been adequately immunized against measles, or whose immunity has decreased since childhood.
Prevention:
Measles is prevented by a vaccine that can be given before, or within 3 days after, exposure to the disease. In most children, measles vaccine is given as part of the mumps-measles-rubella immunizations (MMR) - one given at age 15 months, and the second at 11 to 12 years. Measles vaccine is not usually given to infants younger than 13 months old, except in times of measles outbreaks. In this case, a dose of measles vaccine alone may be given at 9 months, followed by the usual MMR immunization at 15 months.
Measles vaccine made before 1979 may not have been as effective as vaccine made today. Because of this, doctors often recommend that persons vaccinated before 1980 receive another measles vaccination if a measles outbreak occurs in their area, especially if they are in school. A blood test can be performed to determine a person's immunity and whether they need another immunization.
Measles vaccine should not be given to pregnant women, or to persons with active tuberculosis, leukemia, lymphoma, or depressed immune systems. Also, persons with severe allergies to eggs, or to the antibiotic neomycin, may risk life-threatening reactions to measles vaccine.
Measles vaccine occasionally causes side effects in persons with no underlying health problems. In about 10% of cases there is a fever between 5 and 12 days after vaccination, and in about 5% of cases there is a rash.
In special situations (pregnant women, infants, persons with cancer, tuberculosis, or depressed immune systems), persons exposed to measles can also be protected from infection by an injection of antibodies called gamma globulin. Gamma globulin is given within 6 days of exposure, and it either prevents measles or makes symptoms less severe.
As is the case with all immunization schedules, there are important exceptions and special circumstances. Your doctor should have the most current information regarding recommendations about the measles immunization. |
