The 24th of March every year is set aside to commemorate the World Tuberculosis Day.
As a remarkable day, it is celebrated the world over with activities to draw the attention of all – government, corporate organization, private individual and infected persons to the significance of Tuberculosis to public health.
Over the years, several government and donor-driven efforts have been targeted toward TB elimination.
Interventions such as the Global Funds to Fight AIDS Tuberculosis and Malaria (GF-ATM) supported testing, diagnosis and treatment; while Social and Behavior Change (SBC) interventions addressed and still addressing individual behavior, cultural and structural barriers, and TB service provider behavior change.
The TB scourge took a different dimension globally as case detection dropped as a result of Covid pandemic, political-economic situations and Climate change. However, within that Covid era, Nigeria accelerated in TB case detection with the introduction of innovations like Toll-free number for self-reporting, 3340; Motorised campaigns, Mobile diagnostic Clinic – Wellness in Wheel (WoW) truck and Portable x-rays equipped with Artificial Intelligence and remote radiologists for analysis.

Basic facts about TB
Tuberculosis is caused by Mycobacterium Tuberculosis, a bacilli bacteria that attacks the lungs.
The Mycobacterium that causes TB is a family of 3:
* Mycobacterium ulcerans attacks the nerve, leading to Buruli Ulcer.
* Mycobacterium leprae attacks the Skin and is responsible for Leprosy.
* While Mycobaterium Tuberculosis attacks the lungs, resulting in Tuberculosis.
Aside from attacking the lungs, TB also attacks other parts of the human body exception of the hair and the nails which contain dead cells.

Before someone is presumed TB, the following signs should be present:
1. Cough that last for 2 weeks and beyond
2. Drenching night sweat
3. Unexplainable weight loss or failure to thrive
4. Low fever
Tuberculosis infection outside the lungs is known as Extra-Pulmonary Tuberculosis.
Common signs of Extra-Pulmomary TB are painfull or painless swellings and lumps on any part of the body and skin.
TB treatment is free and the campaign to end community transmission of TB begins in case detection.
Presently, there are Direct Observed Treatment Short Course (DOTS) facilities across the 774 LGAs in Nigeria.
A complete treatment course for TB is 6 months and supervised by a treatment partner for drug adherence.
With the introduction of TB preventive Treatment (TPT), an index person can stay free from developing TB infection after exposure with a TB infected person.
Other facts about Tuberculosis include:
* 25% of human population has latent TB
* TB is the leading cause of death from a single infectious agent above HIV/AIDS
* Nigeria is the first in Africa and 6th globally among 30 high burden countries.
* Nigeria is 3rd with highest burden of childhood TB.
* About 128,000 people die from TB disease yearly in Nigeria
* In 2020 estimated new TB cases were 452,000
* 138,591 were notified in 2020
* 207,785 notified in 2021 (50% increase from 2020).
* 285,561 was notified in 2022
* 18 Nigerians die per hour.
For Childhood TB, Statistics reveal that:
* 47 develop active TB cases every hour and 7 of which are children.
* Inspite of the accelerated efforts that led to rise in TB case detection in 2021 and 2022, only 6% and 7% of child hood TB were detected respectively.
Child TB is of utmost concern because Child TB is sentinel to the presence of TB in the community and a case of Child TB should be traced back to the household.
TB is an active co-mobidity to other communicable and non-communicable diseases like Covid and diabetes Mellitus etc. it should not be down played.
Other factors that predispose a person with TB are immuno suppression due to malnutrition and HIV/AIDS, high risk behaviour like smoking and drinking, and defaulting in TB treatment could lead to Multi-Drug Resistant TB (MDR-TB)
TB test and drugs are free.
If cough persists for more than 2 weeks; if there is failure to gain weight after intentional efforts to do which is often termed ‘unexplainable weight loss’, drenching night sweat and low fever…
Visit any health facility around you for free diagnosis or call the TB toll free numbers of 3340 from any mobile network.
