Tuberculosis Needs More Recognition As a Worldwide Health Threat (Op-Ed)
By
The tuberculosis bacterium, Mycobacterium tuberculosis, is easily spread through coughing or sneezing.
TB is one of the deadliest diseases in human history. The M. tuberculosisbacteria that cause it can spread through the air when an infected person coughs. In its most common form, it causes fatigue, long-lasting coughing fits, weight loss, pain in the chest and night sweats. Those with HIV/AIDS or another disease prevalent in areas where TB is often found are particularly vulnerable to the opportunistic bacteria; TB is a leading cause of death for those with HIV/AIDS.
For many people around the world without access to the antibiotics that kill TB or to sufficient medical care to ensure they complete their lengthy treatments, TB is deadly. Here are four reasons TB should hold the No. 1 spot on the WHO's list:
- TB is the No. 1 infectious-disease killer on the planet, surpassing HIV/AIDS. TB causes roughly 2 million human deaths per year; it will have killed someone by the time you finish reading this article.
- It's inexpensive to cure TB. Yet, we can't manage to stamp it out. Meanwhile, when people start treatment and then stop because they have to move, or don’t understand the importance of finishing treatment, they can develop forms of TB that are resistant to the first line antibiotics that we have relied on for decades.
- Drug-resistant TB is on the rise, and it's deadly. The treatment regimen for people who have drug-resistant TB is brutal, the drugs result in significant side effects and we desperately need new lines of defense to battle these antibiotic-resistant strains.
- Doctors continue to rely on 110-year-old skin tests to diagnose TB, because funding dedicated to finding easier, quicker and cheaper methods has stagnated. There is another way to test, with a blood test known as interferon-gamma release assays or IGRAs. But these tests require that blood be drawn and sent to the lab, and patients may be lost to follow-up or may expose more people in the meantime. Because TB has not been given a high enough priority in the public health world, research efforts to develop better ways to treat and prevent TB have been stymied.
TB should already be wiped off the planet, but we lack the political will and funding focus to deliver it a death blow. Instead, public health officials continue to make major missteps, like leaving it off of the WHO list of antibiotic-resistant bacteria, when it should be center stage. This latest swipe at TB efforts undermines the years of work that TB advocacy groups have done to elevate the cause. [27 Devastating Infectious Diseases]
The WHO said it left TB off its new list because there are "otherdedicated programs"that target TB. The WHO's Global TB Program and Ed TB Strategy, as well as StopTB Partnership and the Global Fund for TB, HIV and Malariaare critical in elevating the message of the urgency around TB, but these programsare not enough. The WHO speaks for the world, and to be included in the list of the agency's world concerns is important.Leaving TB off this list makes it appear that it is less critical than the other bacteria listed — and gives the dangerous impression that TB is under control.
We urge the WHO to include drug-resistant TB on its list, because new lines of defense are urgently needed to head off this surge of drug-resistant TB.
