Simple chronic silicosismay causepeople to have difficulty breathing. Accelerated silicosis occurs after 5 to 15 yearsof exposure of higher levels of silica.Swelling of the lungsand other symptoms occur faster in this type of silicosis than in the simple chronic form. Acute silicosis results from short-term exposure (weeks or months) of large amounts of silica.The lungs become very inflamed and can fill with fluid, causing severe shortness of breath and low blood oxygen levels. A cough, weight loss, and fatigue may also be present. Acute silicosis progresses rapidly and can be fatal within months. People who work in jobs where they are exposed to silica dust (mining, quarrying, construction, sand blasting, stone cutting) are at risk of developing this condition.

However, lung function tests using spirometry are not feasible in young children, and most cases of PIBO develop during early childhood.
