EVERY so often, a pandemic emerges that dramatically alters human society. The Black Death (1347-1351) was one; the Spanish flu of 1918 was another. Now there’s COVID-19. GUEST COLUMN: SHADRECK CHIRIKURE Archaeologists have long studied diseases in past populations. To do so, they consider a wide array of evidence: settlement layout, burials, funerary remains, and human skeletons. For example, because of archaeologists we know that the damaging impact of epidemics prompted the abandonment of settlements at Akrokrowa in Ghana during the early 14th century. About 76 infant burial sites at an abandoned settlement that now forms part of the Mapungubwe World Heritage site in the Limpopo Valley of South Africa suggest a pandemic hit the people living there after 1000 AD. Archaeological and historical insights also expose some of the strategies that societies adopted to deal with pandemics. These included burning settlements as a disinfectant and shifting settlements to new locations. Social distancing was practised by dispersing settlements. Archaeologists’ findings at Mwenezi in southern Zimbabwe also show that it was a taboo to touch or interfere with remains of the dead, lest diseases be transmitted in this way. In the late 1960s, some members of an archaeological dig excavating 13th century house floors in Phalaborwa, South Africa, refused to keep working after encountering burials they believed were sacred. They also worried that the burials were related to a disease outbreak. Social distancing and isolation have become watchwords during the COVID-19 pandemic. From archaeology, we know that the same practices formed a critical part of managing pandemics in historical African societies. In what is Zimbabwe today, the Shona people in the 17th and 18th centuries isolated those suffering from infectious diseases — such as leprosy — in temporary residential structures. This meant that very few people could come into contact with the sick. In some cases, corpses were burnt to avoid spreading the contagion. Humans have a propensity to relax and shift priorities once calamities are over. Data collected by archaeologists, that show how indigenous knowledge systems helped ancient societies in Africa deal with the shock of illness and pandemics, can help remind policymakers of different ways to prepare modern societies for the same issues. Social distancing and isolation Research at the early urban settlement of K2, part of the Mapungubwe World Heritage site, has thrown significant light on ancient pandemics. The inhabitants of K2 (which dates back to between 1 000AD and 1 200AD) thrived on crop agriculture, cattle raising, metallurgy, hunting and collecting food from the forest. They had well-developed local and regional economies that fed into international networks of exchange with the Indian Ocean rim. Swahili towns of East Africa acted as conduits. Archaeological work at K2 uncovered an unusually high number of burials (94), 76 of which belonged to infants in the 0-4 age category. This translated into a mortality rate of 5%
