World Health Organization reports a concerning increase in TB diagnoses, but also notes improvements in screening and a decline in deaths.
What Happened: Global TB Statistics in 2024
The World Health Organization (WHO) announced on wednesday that the number of people diagnosed with tuberculosis (TB) worldwide rose again in 2024, surpassing the previous year’s record. Approximately 8.3 million people globally where newly diagnosed with TB. This figure represents 78% of the estimated 10.6 million people who actually fell ill with the disease in 2024, according to the WHO.
despite the increase in diagnoses, there was positive news regarding mortality rates. Globally, TB-related deaths fell to 1.23 million in 2024, a decrease from 1.25 million in 2023.
Why the Increase? Context and contributing factors
WHO officials attribute the rise in reported cases to improved screening and treatment programs following disruptions caused by the COVID-19 pandemic. During the pandemic, resources were diverted, and access to healthcare was limited, leading to a backlog in TB diagnoses. The current increase suggests that healthcare systems are recovering and actively identifying more cases.
Though, the increase also highlights the ongoing challenges in TB control, notably in resource-limited settings. Factors contributing to the spread of TB include poverty, malnutrition, HIV co-infection, and limited access to healthcare.
U.S. Trends
The United States has also experienced a rise in TB cases, reaching the highest level in over a dozen years. Preliminary data indicates that the majority of these cases are diagnosed in individuals born in other countries. This suggests the importance of screening programs for immigrants and refugees, as well as addressing TB transmission within communities with high rates of immigration.
Understanding Tuberculosis: Symptoms, Transmission, and Treatment
Tuberculosis is an infectious disease caused by bacteria (Mycobacterium tuberculosis) that primarily attacks the lungs. It is spread through the air when a person with active TB coughs, sneezes, speaks, or sings. Symptoms of TB can include:
- Persistent cough (lasting three or more weeks)
- Coughing up blood or sputum
- Chest pain
- Weakness or fatigue
- Weight loss
- Fever
- Night sweats
It’s estimated that roughly a quarter of the global population is infected with TB bacteria, but only a small percentage develop active disease. Latent TB infection (LTBI) is a state where the bacteria are present in the body but are not actively causing illness. LTBI can be treated to prevent progression to active TB.
Treatment for TB typically involves a course of antibiotics lasting several months. Adherence to the full course of treatment is crucial to prevent drug resistance.
