Enhancing SARS-CoV-2 surveillance at ports of entry between South Africa and Zimbabwe due to anticipated increased human mobility during the festive period

Abstract

The temporary labour migration of Zimbabwean citizens to South Africa (SA) is a long-standing practice. However, there has been an increased influx of Zimbabweans into SA (and other countries in the African region) over the past twenty years. A large proportion of Zim- babweans residing in SA are undocumented, making it difficult to establish their exact number, with estimates ranging from 2 to 5 million. In December 2020, an estimated daily average of 30,000 people crossed the Beitbridge border post from South Africa entering Zimbabwe during the festive period. Transmigration between South Africa and Zimbabwe is essential to enable individuals to maintain links and sup- port for their families, especially during the festive periods.
