Scientists at the University of Ghana have successfully sequenced genomes of SARS-CoV-2, the virus responsible for the global COVID-19 pandemic, obtaining important information about the genetic composition of viral strains in 15 of the confirmed cases in Ghana.

The scientists, who work at the Noguchi Memorial Institute for Medical Research (NMIMR – College of Health Sciences) and the West African Centre for Cell Biology of Infectious Pathogens (WACCBIP – College of Basic and Applied Sciences) at the University, analyzed samples from selected cases to gain a comprehensive understanding of the variations of the virus that are present in the country.
Genome sequencing allows for the compilation of the most comprehensive information about an organism’s genetic makeup. Using advanced next-generation sequencing methods, scientists are able to track and compare viral mutations to understand the origins of imported strains and to discover if any novel strains are emerging locally.
“The successful establishment of this sequencing capability at University of Ghana is a significant milestone in Ghana’s response to the pandemic, as it will strengthen surveillance for tracking mutations of the virus and aid in the tracing of the sources of community infections in people with no known contact with confirmed cases,” said Prof. Abraham Anang, Director of NMIMR.
Samples analyzed were taken from two travelers who arrived in Ghana from the UK, one from Norway, one from Hungary, one from India, and one traveler who arrived from the United States through the United Arab Emirates. Nine samples were taken from individuals who had no travel history, who are believed to have acquired the infection locally.
The information from the sequence data has been shared with scientists around the world through an open access platform known as the Global Initiative on Sharing All Influenza Data (GISAID) database, where other sequences from various countries are stored.
COVID-19 cases in Ghana have now hit 566. The capital city Accra has the highest record of 452, Ashanti Region – 49, Easten Region – 32, Upper West and Upper East all have 7 and 4 cases respectively.
Northern Region has 10 cases so far while the Central and Western Regions have also recorded 1 cases each. Volta Region closes with 9 cases. There have been 4 recoveries and 8 deaths so far.
Out of the 566 cases, 2 are severe while 522 cases are confirmed to be mild. Coronavirus cases in April→
According to the Ghana Health Service, the new cases were detected over the past twelve (12) days since the introduction of the enhanced surveillance.
