A return to tighter lockdown restrictions could be harder to enforce

New research by academics led by the University of Pretoria models three scenarios for the spread of Covid-19 in South Africa, combining previous models with new data. The results paint a worrying picture for the rate of infection against the country’s ICU capacity, amid decreasing levels of compliance to lockdown regulations. To curb the spread of Covid-19, many governments around the world have implemented tiered lockdowns with varying degrees of stringency. Lockdown levels are typically increased when the disease spreads and reduced when the disease abates.
