Spore Sickness was a common term used to describe any number of illnesses that could be contracted by breathing in the adaptogenic spores of the multitude of fungi that were native to the planet Drongar. The spore sickness was especially common among offworlders, who had not yet adjusted to Drongar's unique environment. For this reason, incoming starships regularly cleaned their ventilation systems before and after arriving at Drongar. In most cases, spore sickness caused damage to the lungs, forcing the body to battle the spores by raising the body temperature to exceptionally high levels, essentially cooking an individual in their own body fluids. However, the spores were only dangerous when encountered in the atmosphere. At ground levels, the spores appeared to be harmless. Such diseases included spleen-rot and Ascomycetous pneumoconiosis.
