Tennessee observes World Tuberculosis
Day
From Staff Reports
Today has been designated as World TB Day in
order to promote awareness, knowledge and motivation for action
against tuberculosis worldwide. Each year, two million people
die from TB and someone in the world is newly infected with
the disease every second.
There were 313 reported cases of tuberculosis
in Tennessee in 2001, a decrease of the 18.5 percent from
the previous year. Although tuberculosis rates are at an all-time
low in Tennessee, they still remain the highest in the nation
and the percentage of cases occurring in foreign-born persons
immigrating to Tennessee remains high.
Fifty percent of U.S. cases and 14 percent of
Tennessee cases last year occurred in foreign born persons.
From 1986 to 2000 the number of TB cases among foreign born
persons in the U.S. increased by 53.4 percent from 4,925 cases
to 7,554 cases, but the number of people who are infected
is actually much higher. People who are infected with TB bacteria
but do not have the disease are not ill, do not have symptoms
and cannot spread the infection to others. They could, however,
develop active disease at anytime.
Immigrants from high TB prevalence countries
in Asia, Africa, Latin America, Eastern Europe and Russia
are much more likely to be infected with TB and they may develop
active contagious disease once they are in the U.S. The Centers
for Disease Control and Prevention estimates that at least
seven million foreign born persons in the U.S. are infected
with TB and that two out of three percent will develop the
disease unless they complete medication to stop the progression
to active disease.
"The Tennessee Department of Health recommends
that people at a high risk for TB have a skin test to find
out if they have TB infection," said Dr. Allen Craig, State
Epidemiologist. Persons at a high risk for active TB in Tennessee
are those with HIV infection, AIDS close contacts to an active
case of TB, homeless persons, incarcerated individuals, and
intravenous drug users.
The Department offers free screening and testing
for high risk individuals in an effort to identify people
who are infected with TB and provide treatment to prevent
them from becoming ill. The tests are available at all county
health departments and all information is confidential.
People who have been vaccinated with BGG, a vaccine
for TB often given to infants and small children in other
countries where the disease is common, also need to have a
skin test because they still could have the TB infection.
Many of the people have been told that they should not get
skin tested, but this is not correct according to the most
current information.
If TB is diagnosed, drug treatment will be needed
to cure the disease. The drugs are also provided free of charge
by the health department. "TB can almost always be cured,
but catching the disease early and starting treatment promptly
is important," Craig said. "The longer treatment is delayed,
the harder the disease is to treat and the more people are
exposed."
