Overview

Classification=

Classification of silicosis is made according to the disease's severity, onset, and rapidity of progression. These include:

  • Chronic silicosis

Occurs after 15-20 years of exposure to moderate to low levels of silica dust. Chronic silicosis itself is further subdivided into simple and complicated silicoses. This is the most common type of silicosis. Patients with this type of silicosis may not have obvious symptoms, so a chest X-ray is necessary to determine if there is lung damage.

  • Asymptomatic silicosis

Early cases of the disease do not present any symptoms

  • Accelerated silicosis

Silicosis that develops 5-10 years after high exposure to silica dust. Symptoms include severe shortness of breath, weakness, and weight loss.

  • Acute silicosis

Silicosis that develops a few months to 2 years after exposure to very high concentrations of silica dust. Symptoms of acute silicosis include severe disabling shortness of breath, weakness, and weight loss, often leading to death.
