COVID-19 symptoms and SARS-CoV-2 infection among people living with HIV in the US: the MACS/WIHS combined cohort study

Background: SARS-CoV-2 infection among People Living With HIV (PLWH) is not well-described. Objective: To study COVID-19 symptoms and SARS-CoV-2 PCR-based swab testing among participants of the Multicenter AIDS Cohort Study (MACS) and Women’s Interagency HIV Study (WIHS). Methods: A telephone survey was collected April-June 30, 2020. Symptom and testing prevalence were explored. Multivariable logistic regression was used to examine the factors associated with SARS-CoV-2 positivity. Results: The survey was completed by 3411 participants, including 2078 (61%) PLWH and 1333 HIV-seronegative (SN) participants from across the US. Thirteen percent (n = 441) were tested for SARS-CoV-2 infection (13.4% of PLWH vs 12.2% of SN). Among those tested, positivity was higher in PLWH than SN (11.2% vs 6.1%, p = 0.08). Reasons for not being tested included testing not being available (30% of participants) and not knowing where to get tested (16% of participants). Most symptoms reported since January 2020 were similar in PLWH and SN, including headache (23% vs. 24%), myalgias (19% vs 18%), shortness of breath (14% vs 13%), chills (12% vs 10%), fever (6% vs 6%) and loss of taste or smell (6% vs 7%). Among PLWH who tested positive for SARS-CoV-2 DNA, the most common symptoms were headache (71%), myalgia (68%), cough (68%) and chills (65%). In multivariable analysis among those tested, the odds of SARS-CoV-2 positivity were higher among PLWH than SN (aOR = 2.22 95%CI = 01.01–4.85, p = 0.046) and among those living with others versus living alone (aOR = 2.95 95%CI = 1.18–7.40). Conclusion: Prevalence and type of COVID-19 symptoms were similar in PLWH and SN. SARS-CoV-2 infection may be elevated among PLWH

Enterprise Ownership, Market Competition and Manufacturing Priorities in a Sub-Saharan African Emerging Economy: Evidence from Ghana

The economic liberalization policies being implemented by many African economies have led to significant efficiency and performance improvements in the activities of privately owned enterprises. This study examines the effect of the economic liberalization policies on the entrepreneurial development of domestic-owned enterprises. This is done by examining how the type of enterprise ownership (wholly domestic-owned enterprises vs. foreign–domestic joint ventures enterprises), and the increase in competition affect the manufacturing priorities of privately owned enterprises in Ghana. The results show that the enhancement in manufacturing efficiency and quality improvement in privately owned enterprises could be traced to the activities of foreign–domestic joint venture enterprises. However, as market competition increases, wholly domestic-owned enterprises emphasize manufacturing efficiency and quality improvement more that foreign–domestic joint venture enterprises. Implications for policy are discussed.
