Association between mobility, non-pharmaceutical interventions, and COVID-19 transmission in Ghana: A modelling study using mobile phone data

Governments around the world have implemented non-pharmaceutical interventions to limit the transmission of COVID-19. Here we assess if increasing NPI stringency was associated with a reduction in COVID-19 cases in Ghana. While lockdowns and physical distancing have proven effective for reducing COVID-19 transmission, there is still limited understanding of how NPI measures are reflected in indicators of human mobility. Further, there is a lack of understanding about how findings from high-income settings correspond to low and middle-income contexts. In this study, we assess the relationship between indicators of human mobility, NPIs, and estimates of Rt, a real-time measure of the intensity of COVID-19 transmission. We construct a multilevel generalised linear mixed model, combining local disease surveillance data from subnational districts of Ghana with the timing of NPIs and indicators of human mobility from Google and Vodafone Ghana. We observe a relationship between reductions in human mobility and decreases in Rt during the early stages of the COVID-19 epidemic in Ghana. We find that the strength of this relationship varies through time, decreasing after the most stringent period of interventions in the early epidemic. Our findings demonstrate how the association of NPI and mobility indicators with COVID-19 transmission may vary through time. Further, we demonstrate the utility of combining local disease surveillance data with large scale human mobility data to augment existing surveillance capacity to monitor the impact of NPI policies.

Cost analysis of health workforce investments for COVID-19 response in Ghana.

The COVID-19 pandemic had multiple adverse impacts on the health workforce that constrained their capacity to contain and combat the disease. To mitigate the impact of the pandemic on the Ghanaian health workforce, the government implemented a strategy to recruit qualified but unemployed health workers to fill staffing gaps and incentivise all public sector health workers. This paper estimated the cost of the new recruitments and incentives given to health workers and presented lessons for health workforce planning in future health emergencies towards health systems resilience. Between March and November 2020, 45 107 health workers were recruited, representing a 35% boost in the public sector health workforce capacity, and an increase in the recurrent public health sector wage bill by about GHS103 229 420 (US$17 798 176) per month, and about GHS1.24 billion (US$213.58 million) per annum. To incentivise the health workforce, the government announced a waiver of personal income taxes for all health workers in the public sector from April to December 2020 and offered a 50% additional allowance to some health workers. We estimate that the Government of Ghana spent about GH¢16.93 million (equivalent to US$2.92 million) monthly as COVID-19 response incentives, which translates into US$35 million by the end of 2020. Ghana invested considerably in health workforce recruitment and incentives to respond to the COVID-19 pandemic, resulting in an almost 37% increase in the public sector wage bill. Strengthening investments in decent employment, protection and safety for the health workforce using the various resources are helpful in addressing future pandemics.

Genetic diversity of SARS-CoV-2 infections in Ghana from 2020-2021.

The COVID-19 pandemic is one of the fastest evolving pandemics in recent history. As such, the SARS-CoV-2 viral evolution needs to be continuously tracked. This study sequenced 1123 SARS-CoV-2 genomes from patient isolates (121 from arriving travellers and 1002 from communities) to track the molecular evolution and spatio-temporal dynamics of the SARS-CoV-2 variants in Ghana. The data show that initial local transmission was dominated by B.1.1 lineage, but the second wave was overwhelmingly driven by the Alpha variant. Subsequently, an unheralded variant under monitoring, B.1.1.318, dominated transmission from April to June 2021 before being displaced by Delta variants, which were introduced into community transmission in May 2021. Mutational analysis indicated that variants that took hold in Ghana harboured transmission enhancing and immune escape spike substitutions. The observed rapid viral evolution demonstrates the potential for emergence of novel variants with greater mutational fitness as observed in other parts of the world.

Overview of preparedness and response to COVID-19 in Ghana

Summary The Coronavirus disease 2019 (COVID-19) outbreak in Ghana is part of an ongoing pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The first two cases of COVID-19 were confirmed in Ghana on 12th March 2020. COVID-19 was consequently declared a Public Health Emergency of National Concern, triggering several response actions, including enhanced surveillance, case detection, case management and contact tracing, closure of borders, suspension of international flights, ban on social gatherings and closure of schools. Preparedness and response plans were activated for implementation at the national, regional, district and community levels. Ghana's Strategic approaches were to limit and stop the importation of cases;detect and contain cases early;expand infrastructure, logistics and capacity to provide quality healthcare for the sick;minimise disruption to social and economic life and increase the domestic capacity of all sectors to deal with existing and future shocks. The health sector strategic frame focused on testing, treatment, and tracking. As of 31st December 2020, a total of 535,168 cases, including 335 deaths (CFR: 0.61%), have been confirmed with 53,928 recoveries and 905 active cases. All the regions have reported cases, with Greater Accra reporting the highest number. The response actions in Ghana have seen high-level political commitment, appropriate and timely decisions, and a careful balance of public health interventions with economic and socio-cultural dynamics. Efforts are ongoing to intensify non-pharmaceutical interventions, sustain the gains made so far and introduce COVID-19 vaccines to reduce the public health burden of the disease in Ghana Funding None declared

Infection prevention and control compliance among exposed healthcare workers in COVID-19 treatment centers in Ghana: A descriptive cross-sectional study.

Compliance with infection prevention and control (IPC) protocols is critical in minimizing the risk of coronavirus disease (COVID-19) infection among healthcare workers. However, data on IPC compliance among healthcare workers in COVID-19 treatment centers are unknown in Ghana. This study aims to assess IPC compliance among healthcare workers in Ghana's COVID-19 treatment centers. The study was a secondary analysis of data, which was initially collected to determine the level of risk of COVID-19 virus infection among healthcare workers in Ghana. Quantitative data were conveniently collected using the WHO COVID-19 risk assessment tool. We analyzed the data using descriptive statistics and logistic regression analyses. We observed that IPC compliance during healthcare interactions was 88.4% for hand hygiene and 90.6% for Personal Protective Equipment (PPE) usage; IPC compliance while performing aerosol-generating procedures (AGPs), was 97.5% for hand hygiene and 97.5% for PPE usage. For hand hygiene during healthcare interactions, lower compliance was seen among nonclinical staff [OR (odds ratio): 0.43; 95% CI (Confidence interval): 0.21-0.89], and healthcare workers with secondary level qualification (OR: 0.24; 95% CI: 0.08-0.71). Midwives (OR: 0.29; 95% CI: 0.09-0.93) and Pharmacists (OR: 0.15; 95% CI: 0.02-0.92) compliance with hand hygiene was significantly lower than registered nurses. For PPE usage during healthcare interactions, lower compliance was seen among healthcare workers who were separated/divorced/widowed (OR: 0.08; 95% CI: 0.01-0.43), those with secondary level qualifications (OR 0.08; 95% CI 0.01-0.43), non-clinical staff (OR 0.16 95% CI 0.07-0.35), cleaners (OR: 0.16; 95% CI: 0.05-0.52), pharmacists (OR: 0.07; 95% CI: 0.01-0.49) and among healthcare workers who reported of insufficiency of PPEs (OR: 0.33; 95% CI: 0.14-0.77). Generally, healthcare workers' infection prevention and control compliance were high, but this compliance differs across the different groups of health professionals in the treatment centers. Ensuring an adequate supply of IPC logistics coupled with behavior change interventions and paying particular attention to nonclinical staff is critical in minimizing the risk of COVID-19 transmission in the treatment centers.

Clinical characteristics, treatment regimen and duration of hospitalization among COVID-19 patients in Ghana: a retrospective cohort study.

INTRODUCTION: COVID-19 is a global pandemic seen in modern times. The clinical characteristics, treatment regimen and duration of hospitalization of COVID-19 patients remain unclear in Ghana. METHODS: we retrospectively reviewed the secondary data of 307 discharged COVID-19 patients to characterize their demographics, clinical symptoms, treatment regimen given and duration of hospitalization. RESULTS: the mean age and temperature of the patients were 37.9 years and 36.3°C, respectively. The majority (85.7%) of the cases reviewed were asymptomatic; for those presenting with symptoms, the main ones were cough (50%), fever (29.6%), headache (27.3%), and sore throat (22.7%). Comorbidities were present in 25.1% of the patients; the popularly reported comorbidities were hypertension (71.4%), asthma (7.8%) and diabetes (6.5%). The average duration of hospitalization was 13.8 days, and the duration of hospitalization for patients managed with azithromycin + chloroquine (AZ+CQ) was 10.4 days, followed closely by those managed with hydroxychloroquine (HCQ) only, 11.0 days. There was longer duration of hospitalization among patients who received AZ only compared to patients receiving AZ + CQ (3.24 ± 1.10 days, p=0.037; 95% CI 0.11, 6.37). Linear regression analysis showed that the duration of hospitalization for patients who received AZ only was 2.7 days, which was higher than that of patients who received AZ+CQ and HCQ only (95% CI 0.44, 4.93; p=0.019). CONCLUSION: in this cohort of COVID-19 patients, the common symptoms were cough, fever, headache, and sore throat. The use of AZ+CQ or HCQ only as a therapy for managing COVID-19 patients shortened the duration of hospitalization.

Healthcare Workers Exposure Risk Assessment: A Survey among Frontline Workers in Designated COVID-19 Treatment Centers in Ghana.

BACKGROUND: Healthcare workers (HCWs) are faced with an elevated risk of exposure to SARS-COV-2 due to the clinical procedures they perform on COVID-19 patients. However, data for frontline HCWs level of exposure and risk of COVID-19 virus infection are limited. OBJECTIVE: We investigated the level of exposure and risk of COVID-19 virus infection among HCWs in COVID-19 treatment centers in Ghana. METHODS: A cross-sectional study was utilized in this study and HCWs were invited by convenience to participate in the study, 408 HCWs in 4 COVID-19 treatment centers participated in the study. Adherence to infection prevention and control (IPC) measures were used to categorized HCWs as low or high risk of COVID-19 virus infection. The WHO COVID-19 risk assessment tool was used to collect quantitative data from the study participants. RESULTS: There was a high (N = 328, 80.4%) level of occupational exposure to the COVID-19 virus. However, only 14.0% of the exposed HCWs were at high risk of COVID-19 virus infection. Healthcare workers who performed or were present during any aerosol-generating procedures (AGP) were 23.8 times more likely to be exposed compared to HCWs who did not perform or were absent during any AGP (AOR 23.83; 95% CI: 18.45, 39.20). High risk of COVID-19 virus infection was less likely among registered nurses (AOR = 0.09; 95% CI: 0.02, 0.60), HCWs who performed or were present during any AGP (AOR = 0.05; 95% CI: 0.01, 0.50) and HCWs with a master's degree qualification (AOR 0.06; 95% CI: 0.01, 0.63). CONCLUSION: Despite the high level of exposure to the COVID-19 virus among HCWs in the treatment centers, only 14.0% were at high risk of COVID-19 virus infection. To protect this group of HCWs, treatment centers and HCWs should continue to adhere to WHO and national IPC protocols in managing of COVID-19 cases.
