Unhygienic conditions, dehydration, dysentery and scurvy led to a high mortality rate, on average 15% and up to a third of captives. Often the ships carried hundreds of slaves, who were chained tightly to plank beds.
The lack of sanitation and suffocating conditions meant there was a constant threat of disease. Epidemics of fever, dysentery (the ‘flux’) and smallpox were frequent. Captives endured these conditions for about two months, sometimes longer.
