State Public Health Law requires that all college and university students
enrolled for at least six (6) semester hours or the equivalent per semester,
or at least four (4) hours per quarter, complete and return vaccination
documentation to Barnard College Health Services.

- WHAT
IS MENINGOCOCCAL DISEASE?
-
- This is an illness caused by a
particular bacterium, Neisseria meningitides. When this bacterium
spreads from a local area as the nose to the bloodstream, or causes
inflammation of the membranes surrounding the spinal cord and brain, it is
an extremely serious, potentially fatal infection. About 12% of those who
contract meningococcal meningitis or septicemia (blood infection) will die
from the disease.
-
- It is important to realize that
about 10% of the general population carry meningococcal bacteria in the nose
and throat in a harmless state. This carrier state lasts days to months
before spontaneously disappearing. During an epidemic, carrier rates may
approach 95%, yet fewer than 1% become ill. The body’s own defense
mechanisms, or immune system, play a powerful role in limiting illness.
-
- HOW DOES
IT SPREAD?
-
- Neisseria meningitides can
be transmitted via droplets of respiratory secretions, and through direct
contact (kissing or sharing items such as drinking glasses, straws or
cigarettes) with an infected partner. Casual contact does not usually result
in spread of the bacterium, since it can only live a few minutes outside of
the body.
-
- If one has had intimate contact
with someone diagnosed with meningococcal disease, prompt treatment with one
or two doses of antibiotics such as ciprofloxin or rifampin is used to
prevent illness.
-
- WHO IS
AT RISK?
-
- Anyone can come in contact with
the bacterium that causes the disease, but certain social behaviors seem to
put students at increased risk. Smoking and smoke exposure, bar patronage,
excessive drinking and sleep deprivation suppress the immune system and put
some students at higher risk. Dormitory living also seems to increase the
risk, particularly among first-year students.
-
-
WHAT ARE THE SYMPTOMS?
-
- Early symptoms include fever,
severe, sudden headache, stiff neck, rash, nausea,
vomiting and lethargy. Students are urged to seek medical attention
immediately if they experience several of these symptoms concurrently as the
disease progresses rapidly and prompt treatment improves the outcome.
-
- WHAT
IS THE RISK OF BEING INFECTED?
-
- There has been a great deal of
talk about the increase in meningococcal outbreaks on college campuses over
the last decade. Although this is true, this is still an
extremely rare illness. About 100-125 cases occur annually on
college campuses, with about 5-15 student deaths. A recent Maryland study
reported that only 3 out of 100,000 residence hall students contracted the
disease each year. Thus, we are talking about a very serious illness, but
one that few people actually get.
-
- WHAT
DO I DO TO PROTECT MYSELF?
-
- There is a vaccine that will
reduce your risk of infection. This vaccine has been shown to provide
85-100% protection against the most common strains of the disease, including
serogroups A, C, Y and W-135, and lasts for approximately 3-5 years. It
becomes effective about 7-10 days after immunization. Side effects from the
vaccine are mild and infrequent, usually involving redness and pain at the
injection site for 1-2 days. Rarely a fever may occur for a brief period.
-
- This is a safe vaccine that
is almost always well-tolerated. Any Barnard student who is interested in
receiving the meningococcal vaccine should contact her own health provider.
Because of purchase limitations by the manufacturer, we have limited
availability of the vaccine at Barnard. Please call 212-854-2091 with any
questions.
