Confronting High TB Burden

Today, March 24, 2021, is observed as World Tuberculosis (TB) day by the United Nations, with the theme: The Clock Is Ticking. The day is commemorated every year since 1982 to raise awareness and educate the public about the impact of the deadly disease around the world. The UN designated the date in memory of Dr Robert Koch who announced his discovery of Mycobacterium tuberculosis, the organism that causes tuberculosis on March 24, 1882. At a time when TB killed one out of every seven persons in the United States and Europe, Dr Koch’s discovery became the most important step that opened the way towards diagnosing and curing this disease.
However, nearly 150 years after, TB has remained one of the world’s deadliest infectious killers, claiming nearly 4,000 lives and close to 28,000 people falling ill on a daily basis. The Mycobacterium tuberculosis, the TB bacteria, usually attack the lungs, and any other part of the body such as the kidney, spine, and brain, and though not everyone infected with TB bacteria becomes sick, if not properly treated, the disease can be fatal.
The TB bacteria are spread when a person with TB disease of the lungs or throat coughs, speaks or sings with nearby persons breathing in these bacteria and become infected. Symptoms of the disease in the lungs include a bad cough that lasts for three weeks or more; pain in the chest; coughing up blood or sputum; weakness or fatigue; weight loss; loss of appetite; chills; fever; sweating at night.
Tuberculosis mostly affects adults in their most productive years. However, all age groups are at risk with over 95% of cases and deaths occurring in developing countries. The risk of active TB is greater in persons suffering from other medical conditions that impair the immune system with people who are infected with HIV being 18 times more likely to develop active TB.
Worldwide, TB is one of the top 10 causes of death and the leading cause from single infectious agent. In 2019, an estimated 10 million people fell ill with tuberculosis, comprising 5.6 million men, 3.2 million women and 1.2 million children, while a total of 1.4 million people died from the disease (including 208,000 people living with HIV).
In same 2019, the 30 high TB burden countries accounted for 87% of new cases of the disease while eight countries including India, China, the Philippines, Pakistan, Nigeria, Bangladesh and South Africa account for two thirds of the total burden.
Nigeria is the country with the highest TB burden in Africa and the 5th in the world with children, women of reproductive age and people living with HIV the hardest hit. Not less than 400,000 people contract TB while more than 150,000 lives are lost to the disease each year in the country. This is in addition to 63,000 people living with HIV that get it annually.
Tuberculosis incidence in Nigeria is said to have risen from 418,000 cases in 2017 to 429,000 cases in 2018, and deaths also rose from 155,000 to 157,000 within the same period while treatment coverage for the disease remained stagnant at 24%.
On the heels of the first global ministerial conference on TB hosted by the WHO and the Russian government in November, 2017, followed by the UN’s first ever high-level meeting on TB which elevated the discussion about the status of the TB epidemic and how to end it to the level of heads of state and government on September 26, 2018, leading to the political declaration agreed by all UN member-states, in which existing commitments to the Sustainable Development Goals (SDGs) and WHO’s End TB Strategy were reaffirmed and new ones added, on this year’s World TB Day, the global health body calls on everyone to keep the promise to:
Accelerate the End TB Response to reach the target set in Sustainable Development Goals, WHO End TB Strategy, the Moscow Declaration to: End TB and political declaration of the UN High-Level Meeting on TB; diagnose and treat 40 million people with TB by 2022, including 3.5 million children and 1.5 million people with drug-resistant TB; reach 30 million people with TB preventive treatment, including 24 million household contacts of TB patients – 4 million of whom are children under 5 – and 6 million people living with HIV; mobilise sufficient and sustainable financing to reach $13 billion a year to support efforts to end TB; invest in TB research to reach at least $2 billion a year for better science, better tools and better delivery.
As a member-state of the UN and particularly, as a country that is so heavily impacted, The Tide expects Nigeria to be committed to the vision and mission of the WHO in its effort to reverse the negative narrative of TB. To this end, we urge government at all levels in the country to muster the political will and strike right partnership with relevant stakeholders –and strengthen existing ones where necessary – to achieve the desired objective.
Government must also step up continuous sensitisation and advocacy to women and children, especially in the rural areas. Training and retraining of health workers to build and strengthen their capacity in order for them to be able to deliver quality services to the people must be taken seriously. In this regard, efforts must be made to ensure industrial harmony and stability in the primary health care sector in particular and the health sector in general. Continuous and sustainable community engagement and good data collection are as well pivotal to achieving desired results beyond clinical treatment.
It is not untrue that there are many misconceptions about TB. While some believe that tuberculosis is caused by smoking and drinking, others believe that it is caused by witchcraft or even that it is hereditary. The result of such erroneous beliefs is that people ignorantly seek solutions where there are none and compound the problem when they resort to traditional fetish and religious rituals instead of accessing the tested, proven and reliable medical treatment.
Unfortunately, there are yet people who neither are aware of nor believe that tuberculosis testing and treatment are free in public health facilities in Nigeria.
It is the goal of the UN to eliminate tuberculosis by year 2030 and if an estimated 60 million lives were saved through TB diagnosis and treatment between year 2000 and 2019, the target is not unachievable with the right attitude, commitment and action. A TB-free Nigeria is as well possible in record time even as The Clock Is Ticking for ending a preventable and curable deadly disease.
