A Global Perspective on Viral Pneumonia

Abstract:
There is growing global recognition of the importance of viruses as a cause of lower respiratory tract infections (LRIs) from widespread outbreaks such as the recent COVID-19 pandemic, to seasonal viruses such as those caused by influenza and adenovirus. Worldwide, viruses are a common cause of respiratory infections and mortality due to LRIs. Advances in rapid virus detection have led to a greater understanding of their prevalence and importance as etiological agents of illness. With multiple epidemics and pandemics of viral pneumonia over the past several decades, there is an increasing need to understand the global variations and impacts of these viruses. This review summarizes recent global trends in viral pneumonias and provides an overview of current diagnostic, treatment, and imaging challenges in the setting of viral infections.
