WHO Reports Highest TB Cases in 2023 Amid Pandemic Disruptions

The WHO Global Tuberculosis (TB) Report 2023 highlights a significant increase in TB cases globally, with 8 million people diagnosed in 2023. This represents the highest number of cases since the start of global TB monitoring in 1995. The report underscores the urgent need for accelerated efforts to control and prevent TB, as the pandemic-related disruptions have severely impacted TB services worldwide.

Key Points from the WHO TB Report 2023:

  1. Global TB Cases and Mortality:
    • In 2023, 8 million people were diagnosed with TB, marking a substantial increase from previous years.
    • The African region reported 2.5 million new TB cases in 2022, accounting for a quarter of the global total.
  2. Impact of COVID-19:
    • The COVID-19 pandemic caused significant disruptions to TB diagnosis and treatment services. Resources and staff were diverted to COVID-19 response, leading to a decrease in TB case detection in 2020 and subsequent increases in 2021 and 2022.
    • The pandemic also led to increased migration, which contributed to the rise in TB cases as people moved to new areas where they might not have immediate access to healthcare services.
  3. TB in the United States:
    • The U.S. saw a 16% increase in TB cases from 2022 to 2023, with 9,615 cases reported. This is the highest number since 2013.
    • The rate of TB incidence increased by 15%, from 2.5 per 100,000 persons in 2022 to 2.9 in 2023.
    • Most cases in the U.S. were among non-U.S.-born residents, although there was also a notable increase among U.S.-born individuals.

  1. Implications for Public Health:
    • The report emphasizes the need for strengthened public health systems capable of maintaining essential disease prevention and control activities, especially in the face of future pandemics or large-scale crises.
    • Continued progress towards TB elimination requires engaging communities with higher TB rates and their medical providers in elimination efforts.
Preview
  1. Global Response and Challenges:
    • The WHO report indicates that while the TB response is recovering from the pandemic, accelerated efforts are needed to meet global targets for TB control and elimination.
    • The report also highlights the importance of addressing drug-resistant TB, as the number of cases with resistance to key TB drugs remains a significant concern.
In summary, the WHO TB Report 2023 reveals a troubling increase in TB cases globally, exacerbated by the COVID-19 pandemic. Urgent action is required to strengthen public health systems, improve TB diagnosis and treatment, and address the challenges posed by drug-resistant TB.
