Sarcoidosis is a relatively rare disease, affecting people worldwide. The prevalence of sarcoidosis varies across different populations and regions. In the United States, it is estimated that around 10 to 40 cases per 100,000 people are diagnosed with sarcoidosis each year. However, the true prevalence may be higher as many cases go undiagnosed. Sarcoidosis predominantly affects adults between the ages of 20 and 40, with a slightly higher incidence in women than men. It is important to consult a healthcare professional for accurate diagnosis and management of this condition.
