Abstract:
Typhus is an acute febrile disease caused by a series of bacteria called Rickettsia that is transmitted by insects such as lice, fleas, and ticks. This disease has appeared several times in Iran and caused many casualties. There were some therapeutic measures taken by European physicians in Tehran and medical graduates of the Dar al-Fonun school or expatriates who had studied medical courses in Western countries, even though the taken steps were not enough. Due to the lack of sanitation and cleaning products after the outbreak of World War I in March 1917 and its synchronization with the swift outbreak of Typhus in 1918, heavy casualties followed. In this study, we first examine the prevalence of Typhus in the Qajar dynasty in Iran, and will then focus on the pathological importance of this disease history in Iran. After that, we will study the role of Typhus prevalence and World War I in the Persian famine, malnutrition, and food poverty. Moreover, we investigated the role that this great war had in strengthening the spread of this disease and its role in the death of many Iranian people.
