ST. PAUL, MINNESOTA—Evidence of infectious disease has been detected on the remains of two young children unearthed in a sixteenth-century cemetery in northwestern Peru, according to a Live Science report. The children, who were about 18 months old at the time of death, were buried at Huanchaco, near a church built by Spanish colonizers between 1535 and 1540. About 75 percent of the 120 early colonial–era burials in the cemetery contained the remains of children, most of whom were under the age of five at the time of death. The immune systems of such young children are not yet fully developed, making them particularly vulnerable to infectious diseases. Researchers led by Khrystyne Tschinkel of Hamline University determined that the lesions on the children’s shoulders, elbows, wrists, hips, knees, and ankles are consistent with an infection called osteomyelitis variolosa, which is triggered by the smallpox virus. But smallpox, which is thought to have arrived in northwestern Peru with Francisco Pizarro in the late 1530s, does not always leave marks on the bones of the infected, making it difficult to track the spread of the fast-moving disease. “If we start to identify more of these cases, we can start to create a better understanding of how diseases spread and where outbreaks occurred during the early-colonial time period,” Tschinkel said. Read the original scholarly article about this research in International Journal of Paleopathology. To read about ancient child burials in northern Peru, go to "A Society's Sacrifice."
