Rubella - Can it be
Eradicated?
During the 1998 year, there were 345 cases of rubella reported nationwide. This is
double the number of cases reported during any of the past six years.
When compared to the 1950s, this is a very small number, but this mild
disease is still quite capable of doing serious damage to a fetus. This fetal damage is
commonly known as Congenital Rubella Syndrome (CRS).
For most adults, rubella (sometimes referred to as German measles) is usually a mild
disease with a rash and a fever. However, for a woman who contracts the disease in the
early months of a pregnancy, rubella frequently causes death or major damage to her unborn
child.
This damage can be mental retardation, blindness, deafness, and/or other serious outcomes.
The last major epidemic of rubella swept across this country during 1963 and 1964, and
left in its wake over 20,000 permanently damaged infants. During the mid-sixties, a
rubella vaccine was approved for use in the U.S. which was highly effective and well
tolerated by children.
After implementation of a mandatory vaccine program, the numbers of annually reported
cases of this highly contagious viral disease dropped over 99.5%.
Today, the eradication of rubella is of serious concern to the professionals that study
diseases -- epidemiologists. For over 30 years, this very effective, safe, vaccine has
been available and should be capable of totally eradicating this disease, yet cases of
rubella continue to occur.
Rubella has long been considered a childhood disease, but is now striking mostly teenagers
and adults. Current policy in the U.S. is to vaccinate all infants against rubella
using measles-mumps-rubella vaccine, and then to revaccinate either at school entry or at
adolescence. According to the epidemiologists studying this issue, many of those
persons who are currently catching rubella within the borders of the U.S. have been born
in foreign countries which have little or no vaccination program. Unvaccinated persons
arrive in the U.S. mainly from Latin American countries.
The outbreaks that are occurring in the U.S. today are often within Latino communities
among young unvaccinated men. When rubella outbreaks occur in adults, CRS follows.
A nationwide review of CRS from 1985 to 1996 reported that 44% of cases were in Latino
infants.
Armed with this information and keeping in mind that rubella vaccine is inexpensive and
widely available, researchers consider that eradication of rubella and CRS is feasible.
The researchers recommend that efforts be expanded in the areas of routine postpartum
vaccination of susceptible women, in giving attention to adolescents of both sexes, and in
making sure that young men are included in rubella vaccination strategies.
