How many people get Pleurisy?

Pleurisy, an inflammation of the pleura surrounding the lungs, can affect people of all ages, but its incidence varies based on underlying conditions. It is often a complication of infections like pneumonia or viral illnesses, and while exact prevalence rates can differ by population and region, it is generally considered relatively uncommon. The condition may be more frequent in individuals with pre-existing respiratory diseases or those who smoke. Overall, specific statistics on the exact number of cases can be challenging to determine due to varying reporting practices and diagnostic criteria.
