(DDM) — The World Health Organization has introduced new diagnostic guidelines aimed at accelerating the detection and treatment of Tuberculosis, as part of efforts to end one of the world’s deadliest infectious diseases.
The new recommendations, announced to mark World TB Day 2026, focus on the deployment of innovative diagnostic tools that can be used near the point of care, bringing testing closer to patients and significantly reducing delays in treatment.
According to WHO, the newly approved diagnostic tests are portable, easy to use, and capable of delivering results in under one hour. These tools are also more affordable, costing less than half of many existing molecular diagnostic systems, making them particularly suitable for low- and middle-income countries where access to healthcare infrastructure remains limited.
Health experts say the introduction of these tools could transform tuberculosis control efforts globally by enabling early detection, reducing transmission, and improving treatment outcomes. WHO Director-General Tedros Adhanom Ghebreyesus described the innovation as a major step forward in saving lives and expanding access to care.
The guidelines also recommend the adoption of new sample collection methods, including tongue swabs, which make testing easier for individuals who cannot produce sputum. This approach is expected to expand access to diagnosis, particularly among vulnerable populations such as children, the elderly, and individuals with advanced illness.
In addition, WHO highlighted the benefits of sputum pooling, a strategy that combines samples from multiple individuals for testing. This method reduces costs, conserves laboratory resources, and speeds up diagnosis, especially in resource-constrained settings.
Despite significant progress in combating tuberculosis, WHO warns that the disease remains a major global health threat. Over 3,300 people die from TB every day, while more than 29,000 new infections are recorded daily worldwide. Although global efforts have saved an estimated 83 million lives since 2000, funding constraints and limited access to rapid diagnostics threaten to reverse these gains.
Experts stress that scaling up the use of rapid diagnostic tools, alongside strengthening health systems and community engagement, is critical to closing existing gaps in TB detection and treatment. They also emphasize the need for sustained political commitment and investment to ensure universal access to TB services.
WHO further noted that the new diagnostic platforms could be adapted to detect other diseases such as HIV, mpox, and HPV, making healthcare delivery more integrated and efficient. This multi-disease capability aligns with global efforts to build resilient health systems capable of responding to emerging health threats.
As countries mark World TB Day 2026 under the theme “Yes! We can end TB,” WHO is calling on governments, partners, and stakeholders to accelerate the adoption of these innovations, invest in research, and prioritize tuberculosis as a key component of global health security.
The agency maintains that with decisive leadership, adequate funding, and widespread implementation of new technologies, ending tuberculosis is an achievable goal.
