Network for Genomics Surveillance in South Africa - NGS-SA





Webinar Series on COVID-19 Genomic Surveillance in Africa

The Africa Union and AfricaCDC, in partnership with SANBI, KRISP, H3AbioNet and the Africa Centre of Excellence for Genomics of Infectious Diseases have started a weekly Webinar series to capacitate African researchers on the generation and analysis of SARS-CoV-2 genomic data in Africa.

Early transmission of SARS-CoV-2 in South Africa

The Network for Genomic Surveillance in South Africa (NGS-SA) presents a molecular epidemiological study of the first twenty-one SARS-CoV-2 whole genomes sampled in the first port of entry, KwaZulu-Natal (KZN), during the first month of the epidemic.

Snapshot of African SARS-CoV-2 Diversity

This report focuses on the first SARS-CoV-2 388 genomes from Africa. These genomes were accessed from GISAID and analysed against a backdrop of reference sequences. By comparing our viral genomes against others, we can infer how and when SARS-CoV-2 was introduced into Africa and how it has spread within the continent.

Network for Genomic Surveillance in South Africa (NGS-SA)

KRISP is a founding member of the Network for Genomic Surveillance in South Africa. A network of laboratories, scientists and academic institutions that have joined forces to ensure the public health responses to COVID-19 in South Africa have access to the best possible scientific data.

South Africa: How to get the best readings from thermometers

Experts weigh in on how to avoid inaccurate results during Covid-19 testing. Distance, hair and sweat can all affect the reading of the temperature scans you've been experiencing at work, shopping malls and schools.

SA accelerating towards virus peak without capacity, experts warn

With Covid-19 now growing by leaps and bounds in South Africa, a Mail & Guardian survey has spotlighted the nationwide shortage of staff, equipment and facilities needed to cope with the infected people who are set to flood the healthcare system when the outbreak hits its peak.
