15th December 1928 – International Tropical Medical Congress.  Photogravure by the Survey Department, Cairo.  Usage Valid Until 16 March 1929.

Tropical medicine, also called hot regions medicine, is a branch of medicine that deals with the public health of societies in tropical regions that experience hot weather and high humidity. These societies must prepare for seasons of epidemics and diseases that break out, while also coping with poor social and economic circumstances.

This particular branch of medicine has been expanded to the degree that all countries now have Departments of Tropical Medicine due to the increase in international travel that has made the whole world like one country. Besides, new forms of epidemics or diseases have emerged as human populations and environmental tampering increase.

This Congress coincided with the centennial of the Qasr El-Ainy Hospital and School of Medicine founded by Mohammed Ali Pasha. The set of two stamps was thus a double commemorative. The subjects of the designs were selected by the Dean of the Faculty of Medicine, Cairo in April 1928 and accepted by the Postmaster General in May.
