Governing COVID-19: analyzing the effects of policy responses on food systems in Tanzania

From Alpha to Omicron: How Different Variants of Concern of the SARS-Coronavirus-2 Impacted the World

SARS-CoV-2, the virus that causes COVID-19, is prone to mutations and the generation of genetic variants. Since its first outbreak in 2019, SARS-CoV-2 has continually evolved, resulting in the emergence of several lineages and variants of concern (VOC) that have gained more efficient transmission, severity, and immune evasion properties. The World Health Organization has given these variants names according to the letters of the Greek Alphabet, starting with the Alpha (B.1.1.7) variant, which emerged in 2020, followed by the Beta (B.1.351), Gamma (P.1), Delta (B.1.617.2), and Omicron (B.1.1.529) variants. This review explores the genetic variation among different VOCs of SARS-CoV-2 and how the emergence of variants made a global impact on the pandemic.

Effects of COVID-19 on coastal livelihoods in the central region of Ghana

The COVID-19 outbreak effects and related state responses, especially mobility restriction interventions, contributed to disruption in livelihoods in the coastal communities in Ghana. This paper uses an ethnographic approach to analyse the effects of the COVID-19 pandemic and coping strategies adopted by small-scale fishers, fish traders and processors. We argued that focusing solely on the livelihoods of formal sector workers is problematic because it fails to consider the dynamics of informal coastal workers. Findings indicate that fishers, fish traders and processors experienced various effects on food, income, police harassment, and coping strategies, including migration, resorting to reusable face masks and food-compromising practices. Infectious diseases such as COVID-19 impact coastal people and their livelihoods. Therefore, implementing social protection measures to mitigate the effects of pandemics on livelihoods should be better coordinated and well-targeted to reach the most vulnerable. Findings from this study offer pointers to position preparedness and response efforts to future outbreaks in a similar context.
