A pox can be an illness that creates pus-filled pimples or a rash on the skin. Many of the diseases have a modifier before pox, such as chicken pox, smallpox, or monkeypox. Whether the malady name is one word or two varies and one should double-check names that are uncommon. It should be noted that pox is sometimes used to mean the specific disease of syphilis.
Pox may also be used to mean a curse or hex you wish placed upon someone or something.
Pox is not the name of the sores or blisters caused by a pox. This confusion may arise from calling the scars left behind pockmarks.
The plural is either pox or poxes. The adjective form is poxy. It should be noted that poxy is also an informal adjective used outside the United States to signify something as without worth or not of good quality.
