While African Health Sciences has been freely accessible online there have been questions on whether it is Open Access or not. We wish to clearly state that indeed African Health Sciences is Open Access. There are key issues regarding Open Access needing clarification for avoidance of doubt:
- 1. Henceforth, papers in African Health Sciences will be published under the CC BY (Creative Commons Attribution License) 4.0 International. See details on https://creativecomons.org/)
- 2. The copyright owners or the authors grant the 3rd party (perpetually and in advance) the right to disseminate, reproduce, or use the research papers in part or in full, format/medium as long as:
- No substantive errors are introduced in the process
- Attribution of authorship and correct citation details are given
- The referencing details are not changed.
Should the papers be reproduced in part, this must be clearly stated.
- 3. The papers will be freely and universally accessible online in an easily readable format such as XML in at least one widely recognized open access repository such as PUBMED CENTRAL.

The impact of systemic hypertension on outcomes in hospitalized COVID-19 patients – a systematic review
Abstract
Background: Several observational reports from different parts of the world have shown that systemic hypertension (hypertension) was the single commonest comorbid condition in hospitalized COVID-19 patients. Hypertension is also the most prevalent comorbidity reported among patients who developed severe disease, were admitted to Intensive Care Unit, needed mechanical ventilatory support, or who died on admission. The objective of this systematic review is to study the association between hypertension and specific clinical outcomes of COVID-19 disease which are- development of severe COVID-19 disease, need for
admission in the intensive care unit (ICU) or critical care unit (CCU), need for mechanical ventilation or death
Methods: We searched the PubMed, SCOPUS, and Google Scholar databases up till June 28, 2020 for original research articles that documented the risk factors of mortality in patients with COVID-19 using the PRISMA guideline.
Results: One hundred and eighty-two articles were identified using pre-specified search criteria, of which 33 met the study inclusion criteria. Only three were prospective studies. Most studies documented hypertension as the most prevalent comorbidity. The association of hypertension with development of severe COVID-19 disease was not conclusive, majority of studies however found an associated with mortality.
Conclusion: Hypertension affects the clinical course and outcome of COVID-19 disease in many cohorts. Prospective studies are needed to further understand this relationship.
Keywords: Hypertension and COVID-19; SARS –Cov-2; severity; mortality; ICU care; mechanical ventilation.
