Spotted plague

The spotted plague was one of the Three Plagues of Faerûn, a disease highlighted by blistering boils that burst, leaving scattering spots of pock marks.

Acquisition
The spotted plague was spread by skin-to-skin contact and took effect in one day.

Effects
When infected, an individual's flesh broke out in swollen pustules referred to as "spots" or "festers". They eventually burst and left behind permanent pocks scars.

The infection ran throughout the internal structures of the body, rotting away nearly all types of tissues. It caused a temporary loss of balance, reasoning, and sense of spatial awareness, and occasionally vision. In nearly all cases the sense of smell was lost, and this was nearly always permanent.

If a victim of the disease survived past the first two days and nights, a time fraught with mortality, they were usually ensured survival as the plague ran its course. These fortunate souls were often extremely sick for a matter of days and experienced notable weakness for around a month.
