(WS News) – TB was the leading cause of infectious disease-related deaths in 2023 – reclaiming its title which had been replaced by Covid-19 for three years – according to the 2024 Global Tuberculosis Report.
The WHO said its Global Tuberculosis Report 2024, released on Tuesday, highlights “mixed progress in the global fight against TB, with persistent challenges such as significant underfunding”.
While the number of TB-related deaths declined from 1.32m in 2022 to 1.25m last year, the total number of people contracting the infectious disease increased from 7.5m to 8.2m.
However, not all new cases are diagnosed, and WHO estimates that around 10.8m people actually contracted the disease last year.
“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,” WHO chief Tedros Adhanom Ghebreyesus said in a statement.
“WHO urges all countries to make good on the concrete commitments they have made to expand the use of those tools and to end TB.”
The increase in cases between 2022 and 2023 largely reflects global population growth, the report said.
Last year, the TB incidence rate was 134 new cases per 100,000 people — a 0.2 per cent increase compared to 2022.
The disease disproportionately affects people in 30 high-burden countries. Five countries — India, Indonesia, China, Philippines and Pakistan — account for more than half of the global TB burden, with more than a quarter of the cases found in India alone.
According to the report, 55pc of people who developed TB were men, 33pc were women and 12pc were children and young adolescents.
A preventable and curable disease, TB is caused by bacteria and most often affects the lungs. It is spread through the air when people with lung TB cough, sneeze or spit.
The WHO said a significant number of new TB cases were driven by five major risk factors: undernutrition, HIV infection, alcohol use disorders, diabetes, and, especially among men, smoking.
“Global milestones and targets for reducing the TB disease burden are off-track,” the WHO said.
Only $5.7 billion of the $22bn global annual funding target for TB prevention and care was available last year.
“In 2023, TB probably returned to being the world’s leading cause of death from a single infectious agent, following three years in which it was replaced by coronavirus disease,” the WHO added
