Tuberculosis: The Most Lethal Infectious Disease Rebounds
COVID-19 is no longer the most deadliest infectious disease worldwide, as per recent WHO reports. Tuberculosis (TB), a bacterial infection, has once again become the leading cause of death due to infectious diseases globally.
The Rise in Tuberculosis Cases
This week, the World Health Organization (WHO) released a report revealing that 10.8 million people were struck by TB last year. Among them, a staggering 1.25 million individuals succumbed to the illness, marking a significant increase in the number of TB-related fatalities. This statistic underscores the continuing threat and lethality of tuberculosis.
Decrease in COVID-19 Fatalities
In contrast, COVID-19 deaths have witnessed a substantial decrease. Despite claiming 320,000 lives last year, the figure is considerably lower than the initial heights of the pandemic. This reduction in deaths is largely attributed to widespread vaccination programs and advancements in treatment methodologies.
WHO’s Warning: TB’s Remaining Challenge
Dr. Tedros Adhanom Ghebreyesus, the WHO Director-General, highlighted the urgency of TB’s current resurgence. "The fact that TB still kills and sickens so many people is an outrage," he emphasized, when we possess the requisite pharmaceutical tools to prevent, detect, and treat TB.
Dr. Ghebreyesus further stated, "WHO urges all countries to make good on their commitments to expand the use of effective TB prevention and treatment tools, and to end TB."
TB’s Global Impact
TB predominantly affects low- and middle-income nations. Over 50% of all TB cases are concentrated in just five countries: India (26%), Indonesia (10%), China (6.8%), the Philippines (6.8%), and Pakistan (6.3%). This distribution highlights the inequalities in healthcare access that contribute to the continued disparity in TB’s toll.
Causes of the TB Surge
The resurgence in TB can be attributed to various factors:
- Disruptions from the COVID-19 pandemic hindered essential TB services globally.
- Multidrug-resistant TB strains pose an additional threat, exacerbating the disease’s spread and mortality rate.
- Inadequate funding for both TB prevention and treatment efforts has impaired global efforts to combat this exploding health crisis. In 2022, global funding for TB fell short of its target amount by a significant margin.
Brief Overview of Tuberculosis
Tuberculosis is a contagious bacterial infection primarily affecting the lungs. It is typically spread through airborne particles generated by coughing, sneezing, or speaking. Most people infected with TB remain asymptomatic carriers, while active tuberculosis can be extraordinarily contagious and life-threatening if left untreated.
Staying Informed and Engaged
As global attention shifts towards COVID-19, it is crucial to recall that TB remains a formidable and underappreciated threat. Our collective awareness and collaborative efforts are critical in reversing this trend and saving countless lives from this ancient yet modern-day scourge.
