The results of routine determination of the blood group of smallpox patients admitted to a Madras hospital over a six-month period suggest that the distribution of blood groups among such patients and the severity of illness among patients of various blood groups do not support the hypothesis that susceptibility or resistance to this disease is associated in any direct way with the possession of A or B blood group substances or antibodies to them. The results reported and other considerations discussed make it improbable that the distribution of blood groups among the population of South India has been influenced by the endemic prevalence of smallpox in that part of the world.
对一家马德拉斯医院六个月内收治的天花患者进行血型常规测定的结果表明，这些患者的血型分布以及不同血型患者的疾病严重程度并不支持这样一种假说，即对这种疾病的易感性或抵抗力与拥有A或B血型物质或针对它们的抗体有任何直接关联。所报告的结果以及所讨论的其他因素使得南印度人群中的血型分布受到世界该地区天花地方流行率影响的可能性不大。
