The Second World Cholera Pandemic (1826-1849) in the Kingdom of the Two Sicilies with Special Reference to the Towns of San Prisco and Forio d'Ischia

摘要

The second world cholera pandemic in Europe (1829-1849) was significant because of its geographic extent and the enormous numbers of people who fell ill or died. It was also singularly important because it demonstrated the profound levels of ignorance in both Europe and North America concerning the cause, modes of transmission, and treatment of cholera. This paper discusses the pandemic in the Kingdom of the Two Sicilies in great detail. Even though medical and public health authorities in this kingdom had several years to prepare for cholera's eventual arrival in 1836-1837, their elaborate preventive and therapeutic measures proved no more successful than elsewhere. Despite their efforts, it was estimated that there were 32,145 cases of cholera in the city of Naples by July 1837. Some 19,470 people were estimated to have died among the city's then 357,283 population. This amounted to a cholera-specific mortality rate of 54.5/1000 population. Sicily was also severely affected by the epidemic. It was estimated that 69,000 people died of cholera in Sicily, 24,000 of them in the city of Palermo. Two rural towns in the kingdom, San Prisco and Forio d'Ischia, were selected for in-depth epidemiologic study. The former had a population of 3700 in 1836-1837, while the latter had a population of 5500. The economic basis of both towns was agriculture. However, because Forio is located on an island, fishing and sea transport were then also important industries. Cholera appeared in San Prisco in July 1837 and quickly swept through the population. By August, the epidemic was essentially over. It is estimated that some 109 people died from cholera in San Prisco for a disease-specific mortality rate of 29.5/1000 population. The age range of those who died from cholera was 1 to 90 years. The majority of deaths (60.6 %) were among women. The first cases of cholera appeared in Forio d'Ischia in June 1837. The epidemic then peaked in July. It is estimated that approximately 316 people died from cholera in Forio out of a population of 5500. This resulted in a cholera-specific mortality rate of 57.5/1000 population. Among the first 42 fatal cases in whom the disease was documented on their death certificates, ages ranged from 15 to 88 years. The mean age was 52.4 years. The majority of deaths (57.1 %) were among women. We reached beyond the statistics of this epidemic by presenting an in-depth study of the first person to die from cholera in Forio d'Ischia, Nicola Antonio Insante. By focusing on him, we were able to develop a broad account of the social and economic consequences of his death on his family. At the same time, our research demonstrated the resiliency of his immediate and distant descendants. Similarly, we discuss the D'Ambra and Scola families of Forio d'Ischia, and the Caruso and Valenziano families of San Prisco, among whom a number died from cholera in 1837.
