Summary

Transient urticaria was seen in five of 75 cases (six per cent) of malaria in a general hospital in China. The eruption appeared with the rise in temperature and disappeared with defervescence. With one exception none of the individuals gave a history of previous urticaria or other allergic disorder.

Subsequently another case was seen in a civilian who had been a marine. He had repeated bouts of malaria with or without urticaria, and repeated bouts of urticaria apparently independent of malaria. He was also asthmatic and skin tests for several allergens were positive.

A review of the world literature indicated that urticaria in malaria may occur in acute or chronic malaria. It may occur in malaria of any parasitic type. It may be the sole symptom or it may occur together with other symptoms. It may occur once or recur regularly or irregularly.
