Transfusion reaction to inhaled biologic dusts that are small, 5 microns or less in diameter. Biologic dusts include animal or plant proteins, microorganisms, and rarely low-weight chemicals. Usually the chest x-ray is abnormal with HP. In the early stages of the disease the chest x-ray may be normal, while the high resolution CT scan is not.
Once exposure stops, the symptoms usually clear within a day. So it is important to find what is causing the symptoms. When the exposure is work-related the symptoms may improve during days off, only to start up again after returning to work. You may be without symptoms while you are away on vacation, but the symptoms return when you return to work.
Masks are usually not helpful, but respirators can significantly decrease the exposure. However staying away from the cause will help the most. Steroids are used to decrease the inflammation. Bronchodilators are used to relax tightness of the airways.
