What's happened
Tuberculosis (TB) has officially become the leading infectious disease killer globally, surpassing COVID-19. The World Health Organization (WHO) reported 1.25 million TB-related deaths in 2023, while new infections rose to 10.8 million, the highest since monitoring began in 1995. Significant challenges remain in combating the disease, particularly in low-income countries.
What's behind the headline?
Rising Infections
- New TB cases reached 10.8 million in 2023, the highest since 1995.
- 8.5 million of these were newly diagnosed, indicating a significant public health challenge.
Global Disparities
- TB disproportionately affects Southeast Asia, Africa, and the Western Pacific.
- India, Indonesia, China, the Philippines, and Pakistan account for over half of global cases.
Funding Shortfalls
- Global funding for TB prevention and care remains critically low, with only 26% of the $22 billion target met in 2023.
- Low- and middle-income countries face severe funding shortages, impacting their ability to combat TB effectively.
Drug-Resistant TB
- Multidrug-resistant TB (MDR-TB) remains a significant concern, with only 44% of those estimated to have it diagnosed and treated.
- Treatment success rates for MDR-TB have improved but still require urgent attention.
Future Implications
- The WHO emphasizes the need for increased funding and commitment to TB eradication efforts.
- Without substantial investment and action, the goal of reducing TB deaths by 75% by 2025 will remain elusive.
What the papers say
According to the WHO, tuberculosis has reclaimed its position as the leading infectious disease killer, with 1.25 million deaths reported in 2023, as highlighted by The Independent. Dr. Tedros Adhanom Ghebreyesus stated, "The fact that TB still kills and sickens so many people is an outrage, when we have the tools to prevent it, detect it, and treat it." Meanwhile, All Africa notes that while deaths have decreased, the number of new infections has risen, indicating a troubling trend in global health efforts. The report underscores the need for increased funding, particularly in low- and middle-income countries, where 98% of TB cases occur. The SBS report emphasizes that the gap between estimated and reported cases has narrowed, but significant challenges remain, particularly in addressing drug-resistant TB. Overall, the coverage across sources reflects a consensus on the urgency of addressing TB as a critical public health issue.
How we got here
The WHO's Global Tuberculosis Report 2024 reveals a troubling trend: while TB deaths decreased slightly, new infections have surged. This shift highlights ongoing challenges in global health efforts, particularly in low- and middle-income countries where the majority of cases occur.
