November 2nd will mark the first annual World Pneumonia Day created to mobilize efforts to fight pneumonia on a global stage. According to some estimates, this neglected disease is responsible for the deaths of up to two million children each year, potentially killing more children under the age of five than HIV/AIDS, malaria, and measles combined. Thankfully, some of the leading causes of pneumonia are both preventable and treatable – but it is up to the global health community to advocate for action to implement the solutions that are within our reach.
