Pneumonia

Peripneumonia, and pleuritic affections, are to be thus observed: If the fever be acute, and if there be pains on either side, or in both, and if expiration be attended with pain, if cough be present, and the sputa expectorated be of a blond or livid colour, or likewise thin, frothy, and florid…. When pneumonia is at its height…it is bad if he had dyspnoea…and if sweat comes out about the neck and head, for such sweats are bad, as proceeding from the suffocation, rales, and the violence of the disease.

-Hippocrates, [460-375 BC]
