Emergence of new SARS-CoV-2 Variant of Concern Omicron (B.1.1.529) - highlights Africa's research capabilities, but exposes major knowledge gaps, inequities of vaccine distribution, inadequacies in global COVID-19 response and control effortsNearly two years since the start of the SARS-CoV-2 pandemic, which has caused over 5 million deaths, the world continues to be on high COVID-19 alert. The World Health Organization (WHO), in collaboration with national authorities, public health institutions and scientists have been closely monitoring and assessing the evolution of SARS-CoV-2 since January 2020 (WHO 2021a; WHO 2021b). The emergence of specific SARS-CoV-2 variants were characterised as Variant of Interest (VOI) and Variant of Concern (VOC), to prioritise global monitoring and research, and to inform the ongoing global response to the COVID-19 pandemic. The WHO and its international sequencing networks continuously monitor SARS-CoV-2 mutations and inform countries about any changes that may be needed to respond to the variant, and prevent its spread where feasible.
Mitigating lockdown challenges in response to COVID-19 in Sub-Saharan AfricaThe coronavirus disease 2019 (COVID-19) which was first reported in Wuhan, China at the end of 2019 (Luo et al., 2020) has spread across the world with remarkable speed, with the World Health Organization (WHO) officially declaring a pandemic in March, 2020. Most countries in sub-Saharan Africa (SSA) are now reporting an increasing number of cases, both imported and acquired locally. As of April 14th, 2020, a cumulative total of approximately, 10,757 confirmed COVID-19 cases with 520 deaths have been reported within the WHO African Region, with South Africa, Algeria and Cameroon recording the highest number of cases (WHO, 2020a).
COVID-19 travel restrictions and the International Health Regulations – Call for an open debate on easing of travel restrictionsThe COVID-19 pandemic caused by the novel coronavirus (SARS-CoV-2) has made national governments worldwide to mandate several generic infection control measures such as physical distancing, self-isolation, and closure of non-essential shops, restaurants schools, among others. Some models suggest physical distancing would have to persist for 3 months to mitigate the peak effects on health systems and could be required on an intermittent basis for 12 to 18 months (Flaxman et al., 2020).
Li Wenliang, a face to the frontline healthcare worker. The first doctor to notify the emergence of the SARS-CoV-2, (COVID-19), outbreakDr Li Wenliang, who lost his life to the novel coronavirus, SARS-CoV-2, became the face of the threat of SARS-CoV-2 to frontline workers, the clinicians taking care of patients. Li, 34, was an ophthalmologist at Wuhan Central Hospital. On 30th December, 2019, when the Wuhan municipal health service sent out an alert, he reportedly warned a closed group of ex-medical school classmates on the WeChat social media site of “Seven cases of severe acute respiratory syndrome (SARS) like illness with links with the Huanan Seafood Wholesale Market” at his hospital.
Is Africa prepared for tackling the COVID-19 (SARS-CoV-2) epidemic. Lessons from past outbreaks, ongoing pan-African public health efforts, and implications for the futureSoon after the novel coronavirus, SARS-CoV-2 (2019-nCoV), was first identified in a cluster of patients with pneumonia (Li et al., 2020), in the Chinese city of Wuhan on 31 December 2019, rapid human to human transmission was anticipated (Hui et al., 2020). The fast pace of transmission is wreaking havoc and stirring media hype and public health concern (Ippolito et al., 2020) globally. When the World Health Organization (WHO) declared the disease, (now officially named COVID-19) a Public Health Emergency of International Concern (PHEIC) on 31st January 2020 (WHO, 2020a), the Director General Dr Tedros Ghebreyesus justified the decision by stating that WHOs greatest concern was the potential for the virus to spread to countries with weaker health systems.
The continuing 2019-nCoV epidemic threat of novel coronaviruses to global health — The latest 2019 novel coronavirus outbreak in Wuhan, ChinaThe city of Wuhan in China is the focus of global attention due to an outbreak of a febrile respiratory illness due to a coronavirus 2019-nCoV. In December 2019, there was an outbreak of pneumonia of unknown cause in Wuhan, Hubei province in China, with an epidemiological link to the Huanan Seafood Wholesale Market where there was also sale of live animals. Notification of the WHO on 31 Dec 2019 by the Chinese Health Authorities has prompted health authorities in Hong Kong, Macau, and Taiwan to step up border surveillance, and generated concern and fears that it could mark the emergence of a novel and serious threat to public health (WHO, 2020a; Parr, 2020).
