Coronavirus Disease 2019 (COVID-19) threatens to overwhelm our medical infrastructure at the regional level causing spikes in mortality rates because of shortages of critical equipment, like ventilators. Fortunately, with the recent development and widespread deployment of small-scale manufacturing technologies like RepRap-class 3-D printers and open source microcontrollers, mass distributed manufacturing of ventilators has the potential to overcome medical supply shortages. In this study, after providing a background on ventilators, the academic literature is reviewed to find the existing and already openly-published, vetted designs for ventilators systems. ⋯ With the considerably larger motivation of an ongoing pandemic, it is assumed these projects will garner greater attention and resources to make significant progress to reach a functional and easily-replicated system. There is a large amount of future work needed to move open source ventilators up to the level considered scientific-grade equipment, and even further work needed to reach medical-grade hardware. Future work is needed to achieve the potential of this approach by developing policies, updating regulations, and securing funding mechanisms for the development and testing of open source ventilators for both the current COVID19 pandemic as well as for future pandemics and for everyday use in low-resource settings.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of COVID-19, was first detected in China in December 2019 and has rapidly spread throughout the world. Globally, the impact of COVID-19 has been severe with more than half a million deaths over 6 months; in contrast, the HIV pandemic has resulted in over 32 million deaths worldwide over 40 years. This paper reviews the current epidemiology of COVID-19, summarizes its relationship to HIV, identifies synergies in our response, and suggests actions that can be taken to curtail the spread of COVID-19 among persons living with HIV (PLWH). ⋯ Clinical trials to identify potential treatment and prevention options for COVID-19 have included antiretrovirals used to treat HIV that have not been efficacious. Public health responses overlap between the two pandemics including the need for behavior change and containment strategies such as contact tracing. As the SARS-CoV-2 pandemic evolves, the path forward to controlling, preventing, and treating COVID-19 can be informed by lessons learned from HIV as we seek to control the spread of both viral pandemics.

COVID-19 emerged in late 2019 and has rapidly spread through many countries globally. The causative SARS-CoV-2 virus was not known until recently, and there is little or no natural immunity in human populations. ⋯ In just a few months, huge efforts and resources by government, academia, and industry have been thrown into the race to develop a vaccine. This brief review summarizes and discusses the array of technologies being applied to vaccine development, highlighting the strengths and weaknesses of the various approaches.

Multicenter Study Observational Study
Investigating the association between ethnicity and health outcomes in SARS-CoV-2 in a London secondary care population.
Black, Asian and minority ethnic (BAME) populations are emerging as a vulnerable group in the severe acute respiratory syndrome coronavirus disease (SARS-CoV-2) pandemic. We investigated the relationship between ethnicity and health outcomes in SARS-CoV-2. ⋯ BAME patients were more likely to be admitted younger, and to die at a younger age with SARS-CoV-2. Within the BAME cohort, Asian patients were more likely to die but despite this, there was no difference in rates of admission to ICU. The reasons for these disparities are not fully understood and need to be addressed. Investigating ethnicity as a clinical risk factor remains a high public health priority. Studies that consider ethnicity as part of the wider socio-cultural determinant of health are urgently needed.

This study aimed to determine the concordance between CT and nucleic acid testing in diagnosing coronavirus disease (COVID-19) outside its district of origin (Wuhan, China). ⋯ Patients with positive results on nucleic acid testing may or may not have the abnormal CT manifestations that are frequently found in symptomatic patients with a history of exposure to the district of COVID-19 origin.
