Thailand Battles TB and Air Pollution: A Public Health Crossroads

WEDNESDAY, DECEMBER 25, 2024

In the complex landscape of global public health, Thailand finds itself at a critical intersection of tuberculosis management and environmental challenges, with rising PM2.5 levels adding another layer of complexity to respiratory health.

 

The World Health Organization's 2023 statistics paint a sobering picture of tuberculosis (TB) worldwide. Approximately 10.8 million people fell ill with TB last year, including 6.0 million men, 3.6 million women, and 1.3 million children. Tragically, the disease claimed 1.25 million lives, underscoring the urgent need for comprehensive prevention and treatment strategies.

 

 

In Thailand, the situation mirrors global trends. 

 

 

          Thailand's TB Landscape: A Closer Look
 

Dr Kraisorn Totubtieang, Director of the Division of Tuberculosis, provides crucial insights into the national scenario. 

 

"Approximately 155 individuals per 100,000 Thai people are diagnosed with tuberculosis," he explains. "We estimate over 110,000 new cases annually, yet only 65% are diagnosed, leaving more than 40,000 cases unreported."

The challenges are multifaceted. Unlike HIV, TB spreads through respiratory transmission, making it particularly insidious. Approximately 90% of those infected remain asymptomatic initially, with the bacteria potentially lying dormant for years before manifesting when an individual's immune system weakens.

 

 

Current TB prevention faces significant hurdles. There is no comprehensive vaccine for adults, and treatment requires a rigorous six-month medication regimen. 

 

 

Dr Kraisorn highlights the importance of annual chest X-rays, particularly for high-risk groups including the elderly, those with chronic illnesses, and individuals in crowded environments.

         The PM2.5 Connection: A Compounding Health Risk

Dr Chantana Padungtod from the Environmental and Occupational Health Division,  highlighted the increasing levels of PM2.5 pollution, especially during the agricultural burning season. 

 

“Increased PM2.5 levels are not just an environmental issue but a respiratory health concern,” she stated. “The tiny particles can penetrate deep into the lungs and bloodstream, leading to serious health problems, particularly for vulnerable populations such as those with chronic diseases.”

The data is alarming. Ten provinces currently exceed the pollution standard of 37.5 micrograms per cubic metre. Nonthaburi leads with an average of 85.8, while Bangkok follows closely at 82.2.

 

 

With PM2.5 pollution linked to a heightened risk of respiratory infections, including TB, Dr. Chantana asserted that effective air quality management must form a critical part of the strategy to combat TB. 

 

 

“Managing air pollution is vital, as the particles exacerbating the effects of respiratory diseases can potentially increase susceptibility to infections like tuberculosis,” she explained.

 

 

Her concerns were echoed by Dr Kraisorn, who emphasised the direct link between air quality and TB management. 

 

 

"PM2.5 dust particles can adversely affect overall health," he noted. "For individuals with tuberculosis, poor air quality can significantly slow recovery and place additional strain on the body."
 

 


          Silent Threats to the Nation's Economy

In the context of TB's economic impact, Dr. Kraisorn underscored the financial burden posed by the disease on the country. 

 

“Tuberculosis not only strains the healthcare system but it also affects economic productivity. Every year, we lose around 13,000 lives to this disease, highlighting the impact on family income and overall socioeconomic conditions,” he commented.

The Airborne Infection Defence Platform (AIDP): A Regional Collaboration Strategy

The Airborne Infection Defence Platform (AIDP) emerges as a critical mechanism for addressing the complex challenges of respiratory infections across Southeast Asia. 

 

More than just an information-sharing network, the AIDP represents a strategic approach to managing cross-border health risks, particularly in the context of tuberculosis and other airborne diseases.

 

Dr Kraisorn Totubtieang emphasises the platform's significance: "The AIDP is not merely an exchange programme, but a sophisticated collaborative framework designed to strengthen public health systems across ASEAN countries." The platform's primary objectives include:

  • Facilitating real-time information sharing about airborne infections
  • Developing coordinated response strategies for epidemic preparedness
  • Enabling rapid knowledge transfer between national health institutions
  • Supporting standardised screening and detection protocols
  • Providing a unified approach to managing cross-border health challenges

 

For Thailand, the AIDP offers particular strategic advantages. With approximately 40,000 unreported TB cases annually and complex environmental health challenges, the platform provides a critical support mechanism. 

 

 

 

 

"By leveraging collective expertise," Dr Kraisorn noted, "we can develop more sophisticated approaches to detecting, preventing, and treating tuberculosis."

The platform takes on special importance given the regional variations in TB prevalence. Comparative data shows significant disparities: Myanmar's TB rates are approximately three times higher than Thailand's, while Cambodia's are nearly double. This context underscores the value of a collaborative, region-wide approach to respiratory health management.

 

 

Moreover, the AIDP extends beyond mere information exchange. It represents a proactive strategy for epidemic preparedness, allowing countries to learn from each other's experiences, adapt successful interventions, and create more resilient public health systems.

 

 

 

          Looking Forward 

As Thailand works attentively to confront the dual challenges of rising TB rates and worsening air pollution, the Ministry of Public Health remains committed to safeguarding public health through comprehensive strategies that integrate both disease management and environmental controls. 

 

In doing so, they aim to protect the health of the Thai populace while striving to meet the WHO’s goal of ending the TB epidemic by 2030. The initiatives include:

  • Promoting clean energy
  • Raising emissions standards
  • Developing public awareness campaigns
  • Supporting innovative screening technologies

 

According to Dr. Chantana, the proposed Clean Air Act represents a promising step, categorising six different pollutant sources and providing a framework for comprehensive environmental management.

 

Looking ahead, as both tuberculosis and PM2.5 pollution continue to rise, it is imperative for integrated public health efforts to prevail, ensuring that all Thais can access the necessary resources and information to combat these pressing issues effectively.
