This paper examines the challenges posed by the COVID-19 pandemic on the existing health inequalities disproportionately affecting vulnerable populations. It explores the impact of COVID-19 pandemic response measures to "curb the spread" on informal sector workers in Ghana. In Ghana, like many other developing countries, the informal sector was impacted by a higher risk of exposure to the COVID-19 infection and the slew of pandemic response measures, for example, lockdowns and stay-at-home orders, as well as guidelines around social distancing implemented by their governments. Given the high level of precarity that undergirds work in the informal sector and the intersectional forces that contribute to and maintain their marginality—class, race, ethnicity, gender, religion, and geographic location—this paper creates a space for dialogue about the unintended consequences of pandemic response measures on the livelihood security of informal sector workers.

In this paper, we suggest a mathematical model of COVID-19 with multiple variants of the virus under optimal control. Mathematical modeling has been used to gain deeper insights into the transmission of COVID-19, and various prevention and control strategies have been implemented to mitigate its spread. Our model is a SEIR-based model for multi-strains of COVID-19 with 7 compartments. We also consider the circulatory structure to account for the termination of immunity for COVID-19. The model is established in terms of the positivity and boundedness of the solution and the existence of equilibrium points, and the local stability of the solution. As a result of fitting data of COVID-19 in Ghana to the model, the basic reproduction number of the original virus and Delta variant was estimated to be 1.9396, and the basic reproduction number of the Omicron variant was estimated to be 3.4905, which is 1.8 times larger than that. We observe that even small differences in the incubation and recovery periods of two strains with the same initial transmission rate resulted in large differences in the number of infected individuals. In the case of COVID-19, infections caused by the Omicron variant occur 1.5 to 10 times more than those caused by the original virus. In terms of the optimal control strategy, we formulate three control strategies focusing on social distancing, vaccination, and testing-treatment. We have developed an optimal control model for the three strategies outlined above for the multi-strain model using the Pontryagin's Maximum Principle. Through numerical simulations, we analyze three optimal control strategies for each strain and also consider combinations of the two control strategies. As a result of the simulation, all control strategies are effective in reducing disease spread, in particular, vaccination strategies are more effective than the other two control strategies. In addition the combination of the two strategies also reduces the number of infected individuals by 1/10 compared to implementing one strategy, even when mild levels are implemented. Finally, we show that if the testing-treatment strategy is not properly implemented, the number of asymptomatic and unidentified infections may surge. These results could help guide the level of government intervention and prevention strategy formulation. [ABSTRACT FROM AUTHOR]

Achieving urban food security before and after COVID-19 lockdown among urban households' in Ghana is key. This paper compares the pre-and post-COVID-19 lockdown food security status of urban dwellers in lockdown cities of the Greater part of Accra in Ghana using the Rasch and ordered logit model. From a sample of 340 respondents, the study found a significant difference in household food security status and predictors of food security. Prior to COVID-19 households were 'High food secure' (36.4%), but post-COVID-19 lockdown made more households 'Very low food secure' (12.35%). To combat post-COVID-19 lockdown food insecurity in urban agriculture is encouraged. [ABSTRACT FROM AUTHOR]

Chinese imports replace locally manufactured products in developing countries. The import of consumer goods from China to West Africa is closely linked to commercial travel, and China's border restrictions during the Covid outbreak put a near-halt to such travelling. Furthermore, the pandemic caused a global logistics crisis that disrupted supply chains with production in China. This paper asks whether Ghanaian manufacturers and artisanal producers could take advantage of these disruptions to enhance their competitive position. Did China's border closure provide space for local Ghanaian producers to thrive? We address this question by drawing on data collected among Ghanaian plastic manufacturers and furniture makers, who have faced tough competition from Chinese imports. Our analysis shows that supply chain disruptions from China led to the substitution of certain products previously imported from China, and these effects were partially sustained after the Covid-induced barriers to imports from China were removed. However, the disruptions were also costly for many Ghanaian producers, as they depended on Chinese intermediary products, tools, and other inputs. This illustrates how economic lives in Ghana and China have become so profoundly intertwined that indiscriminate decoupling is neither possible nor desirable. [ABSTRACT FROM AUTHOR]

Research on vaccines confirms the crucial role media play in framing discourses and mobilizing public support for successful immunization campaigns. What journalists cover on vaccination issues and their diligence in producing stories can influence attitudes to and uptake of vaccines. This paper contributes to emerging discussions on the role of the media in pandemics and in vaccination programs by interrogating the information seeking and verification practices of journalists reporting on COVID-19 vaccines in Ghana. A cross-sectional online survey was conducted among journalists from June to July 2021 through self-administered questionnaires by means of Google forms. The opinions of 300 respondents, randomly drawn from members of the Ghana Journalists' Association, were solicited and a response rate of 73% obtained. Majority of journalists surveyed relied on official health sources for their information on COVID-19 vaccines (61.5%) and were confident the benefits of vaccines outweigh the risks (70%). While journalists relied on a variety of expert sources, social media platforms served as important sources of information also, with respondents stating a preference for Facebook (48.3%), and WhatsApp (44%). Journalists stated they were guided by sound practices such as source credibility and relevance, but betrayed weaknesses in their verification practices with a third of them admitting to sharing unsolicited information from social media. Journalists in Ghana generally display a positive attitude towards COVID-19 vaccines and regularly search for information from official sources to inform their work, thus making them vital allies in overcoming vaccine hesitancy. Laxity in verification practices, however, makes them inadvertent agents of misinformation. [ABSTRACT FROM AUTHOR]
