An outbreak of tuberculosis at a high school in Olathe, Kansas has infected a total of 28 students as health officials move to put safety measures in place and monitor the bacteria to prevent further exposure.
According to the
Kansas City Star, the state Department of
Health and Environment tested more than 300 students at Olathe
Northwest High School last week after a previous student was
confirmed to have been infected with tuberculosis. On Monday,
March 16, the department started notifying those students who
tested positive and issued a statement saying that eight percent
of the school (27 students, not including the first positive test
case) was confirmed to have been exposed.
“The number of individuals with TB infection does not exceed
what we would anticipate in this setting,” Lougene Marsh,
director of the Johnson County Department of Health and
Environment, said in a press release. “Of course, we had hoped
we wouldn’t find any additional TB cases, but we knew this was a
possibility. That’s why we took such thorough steps to test
everyone who might have been in close contact with the first
confirmed case of TB disease.”
Health officials were quick to note that simply testing positive
for the bacteria does not necessarily mean that students would
develop tuberculosis disease, which is a serious and deadly
illness. So far, none of the students tested have shown symptoms
or signs of the disease – such as coughing, fatigue, chest pain,
fever and chills, and coughing up blood – and those infected with
tuberculosis are not contagious.

“Our biggest thing that we need to pass along to parents is
TB infection is the result of being exposed to someone with TB
disease, but to have TB infection, does not mean you’re sick. To
have TB infection, is not something you can transmit,” said
Phil Griffin, a representative from the Kansas Department of
Health and Environment, to local channel WDAF.
People with tuberculosis disease, however, are contagious and can
pass the illness onto others through the air, via their breath or
cough, though even that may require hours of exposure. Since it
can take up to eight weeks for symptoms of disease to show up
post-infection, the Health Department has scheduled another round
of blood tests for affected students on May 5.
Tuberculosis is the second most deadly infectious disease in the
world – behind only HIV/AIDS – according to the World Health
Organization. About 1.5 million people died from the disease in
2013, and 9 million were infected. In the US alone, 9,582 cases
were documented in 2013.
Last year, Kansas was home to 40 cases of tuberculosis.
Elsewhere in the state, health officials have connected a small
listeria outbreak to ice cream supplied by the Blue Bell company,
reported WDTV. Since January 2014, five people became infected –
three of whom died – and all the cases were traced back to ice
scream served at a Kansas hospital. The patients ate the ice
cream there, and the listeria has been linked to a single machine
at a Blue Bell factory in Texas.
Though rare, listeriosis can be deadly and causes symptoms such
as fever, muscle aches, diarrhea and other gastrointestinal
Blue Bell said that ice cream sold in grocery stores was not
affected, USA Today reported.
