US tuberculosis (TB) cases increased for the second straight year in 2022, according to new data from the Centers for Disease Control and Prevention (CDC)
Certain racial and ethnic groups, including Latinos, saw considerable increases in TB infections.
Let’s explore what this data means for Latinos, and why this population is more vulnerable to TB infections than their white counterparts.
What is Tuberculosis?
TB disease is caused by a bacterium called Mycobacterium tuberculosis, according to the CDC.
TB bacteria spreads through the air and usually targets the lungs but can attack any part of the body such as the kidney, spine, and brain.
If not treated, TB disease can be fatal.
However, not everyone who becomes infected with TB will develop TB disease.
Sometimes, TB bacteria can “sleep” in the body for years without causing any symptoms or harm to the infected person. These latent TB infections (LTBI) are not contagious but can become an active infection at any time without treatment, according to the CDC.
Symptoms of Tuberculosis Disease
Symptoms of TB disease depend on where the infection is in the body, according to the CDC.
If the infection is in the lungs, symptoms may include a bad cough that lasts three weeks or longer, pain in the chest, and coughing up blood or phlegm.
Other symptoms of TB disease include weakness or fatigue, chills, and fever.
Anyone can get TB disease.
But certain groups, such as Latinos and incarcerated and homeless individuals, are more vulnerable to TB because of social, economic, and demographic factors.
For instance, Latinos are more likely to be born in or travel to a country with a higher rate of TB disease, including South America, according to the CDC.
They may also live in multi-family housing and populated neighborhoods where airborne diseases can rapidly spread.
Latinos are also the largest uninsured racial and ethnic group in the US and lack access to quality healthcare, which further impacts their overall health and vulnerability to infectious diseases, such as TB.
All these factors contribute to significant Latino health disparities in TB cases.
In fact, Latinos have a nine times higher TB case rate than Whites and accounted for 30.6% of all US TB infections in 2021, according to the CDC.
Fortunately, with treatment, most cases of TB can be cured.
Many public health departments and clinics offer free or reduced cost TB disease treatment, which is critical for low-income patients, such as Latinos.
Treatment for LTBI does not require home isolation.
Rise of Tuberculosis Cases
While TB is largely controlled in the US, the new CDC data reveals that rates of the disease increased in 2021 and 2022 after a decline from 2012 to 2020.
TB remains the world’s leading infectious disease killer, according to CDC.
“The message is loud and clear – TB is still here. For the second year in a row, TB disease cases in the US have continued to rise, with concerning increases among young children and other groups at increased risk for TB disease,” Dr. Philip LoBue, Director of CDC’s Division of Tuberculosis Elimination, said in a press release.
“Communities, providers, and public health partners must work together to make sure we are reaching the right people with testing and treatment, so we can prevent and stop the spread of TB.”
While a vaccine for TB exists and is used in other countries, it is not widely used in the US because it does not always protect people against the disease and there is a comparatively low risk for TB infection in the US, according to the CDC.
In the meantime, federal agencies such as the CDC are tackling the rise of TB infections from multiple angles. These include TB awareness and education, researching more effective TB treatment options, and making sure healthcare providers know about the latest TB diagnostics and LTBI treatment options.
