WHO Guidance on Tuberculosis and Influenza A (H1N1) Pandemic
The WHO has issued an information note addressing the potential impact of the Influenza A (H1N1) pandemic on tuberculosis patients and healthcare preparedness.
The World Health Organization (WHO) has released a guidance document for healthcare managers and decision-makers regarding the intersection of the Influenza A (H1N1) pandemic and tuberculosis. With nearly all countries reporting cases of the new influenza, and a notable number of deaths occurring in patients with chronic respiratory conditions, concerns have been raised about the potential impact on individuals with active tuberculosis.
The information note emphasizes the need for coordination between tuberculosis programs and pandemic preparedness plans. While tuberculosis programs might need to mobilize resources during a health emergency like an influenza pandemic, it is crucial to prevent a breakdown in tuberculosis service delivery. Conversely, the extensive experience of tuberculosis programs in decentralized care delivery could be beneficial for providing influenza services during severe outbreaks.
Healthcare services are urged to prepare for the added challenge posed by influenza. Respiratory physicians and tuberculosis specialists may serve as key points of reference for patients with pulmonary complications of the pandemic. They are advised to familiarize themselves with WHO recommendations on antiviral medication use. Ensuring the continuity of tuberculosis care, even when healthcare services are overwhelmed by influenza, is paramount, with special attention to vulnerable patients.
Preventive measures, including vaccination and infection control, are highlighted. WHO experts recommend prioritizing healthcare workers for vaccination. Individuals with underlying medical conditions such as tuberculosis should also be considered for vaccination, subject to availability and national priorities. Facilities like sanatoria, tuberculosis hospitals, clinics, and general hospitals must implement measures to limit transmission of both influenza and tuberculosis.
Additionally, the WHO suggests leveraging existing laboratory networks, developed for tuberculosis diagnostics and surveillance, to support pandemic (H1N1) 2009 diagnostics and surveillance, potentially enhancing the overall response to public health crises.
