The Ongoing Battle Against Pneumonia in the Global South

Pneumonia may not always make headlines, but it continues to be a silent killer. This reality resonates across the globe, particularly in vulnerable communities, where healthcare access is often limited. Despite medical progress, this deadly disease claims millions of lives every year, with children under five and the elderly most at risk. As the world grapples with climate change and the lingering effects of the COVID-19 pandemic, the struggle against pneumonia in the Global South continues.

The Burden of Pneumonia in the Global South

Pneumonia is an infection in the lung caused by bacteria, virus, or fungi. Bacterial and viral pneumonias are contagious, while the fungal one is not.

Globally in 2019, pneumonia is responsible for about 2.5 million deaths, with the majority occurring in low-income countries. The WHO highlights that young children and older adults bear the brunt of this preventable disease.

In the wake of the COVID-19 pandemic, many healthcare systems struggled, further complicating access to vaccines and treatments. For communities in urban slums and rural areas, poor air quality and extreme weather events due to climate change have created the perfect conditions for respiratory diseases to thrive.

Global Efforts to Combat Pneumonia

There is hope, though. With proper treatments, contracting pneumonia does not have to be a death sentence. Around the world, efforts are underway to combat pneumonia.

In Bangladesh, for instance, the national government has integrated the pneumococcal vaccine into routine immunization programs. This has contributed to a significant decline in pneumonia deaths among children. Similarly, Nigeria has seen progress with community-based healthcare initiatives that provide better access to diagnostic tools and treatments, as well as life-saving oxygen therapy for children with severe pneumonia.

There are also global organizations, like Every Breath Counts Coalition, that advocate for better pneumonia treatment across the globe, including access to antibiotics and oxygen therapy, particularly in low-income countries. Meanwhile, GAVI’s effort to make  the pneumococcal vaccine more widely available reaches around 700,000 people each year.

Persistent Challenges

Still, challenges remain. Many low-income communities face significant healthcare inequities, where access to timely medical intervention is limited, leading to severe complications. Antimicrobial resistance (AMR) is also making pneumonia harder to treat, as conventional antibiotics become less effective. The WHO warns that AMR could lead to 10 million deaths annually by 2050, with pneumonia among the most affected diseases.

Furthermore, while organizations like the Bill & Melinda Gates Foundation are investing in pneumonia research and treatment innovations, the funding allocated to pneumonia is still limited compared to other global health priorities like malaria or HIV/AIDS.

The Way Forward

Ensuring continued progress in the fight against pneumonia in the Global South requires a multifaceted approach. Government must strengthen healthcare infrastructure to ensure equitable treatment access. For instance, increasing investment in preventive healthcare, such as vaccinations and air pollution control, is foundational. Addressing the impact of climate change on respiratory diseases is also key to mitigating the burden of pneumonia.

While challenges remain, continued collaboration among global health organizations, governments, and researchers offers hope for reducing pneumonia deaths. More financial and technical support is essential to support the development of new, more effective treatments. All in all, strong governance and equitable innovation will be vital to preventing pneumonia from remaining a silent killer in the Global South.
