Kwon, K.S., Park, J.I., et al. 2020. “Evidence of Long-Distance Droplet Transmission of SARS-CoV-2 by Direct Air Flow in a Restaurant in Korea.” Journal of Korean Medical Science, 2020 Nov;35(46):e415.

BackgroundThe transmission mode of severe acute respiratory syndrome coronavirus 2 is primarily known as droplet transmission. However, a recent argument has emerged about the possibility of airborne transmission. On June 17, there was a coronavirus disease 2019 (COVID-19) outbreak in Korea associated with long distance droplet transmission. MethodsThe epidemiological investigation was implemented based on personal […]

Nath, A. and Smith, B., 2020. “Neurological issues during COVID-19: An overview.” Neuroscience Letters, 2020, 135533, ISSN 0304-3940.

COVID-19 has shaken the core of the medical health system. The wide spread death and destruction of patients and health care workers in unprecedented in the modern era. While the pulmonary complications have received the most attention, it is the neurological manifestations that are disabling, persistent and common in patients infected with SARS-CoV-2. The entire […]

Doctors, engineers call on Ontario to address airborne spread of COVID-19 in open letter “Ventilation not Ventilators”

Nearly three dozen engineers and doctors in Ontario are calling on the Health Ministry to better inform the public about the risks of airborne transmission of COVID-19, and improve ventilation standards across the province. In a letter, 21 doctors and 12 engineers and other scientists call on Ontario to update the province’s COVID-19 guidelines, regulations and communication to […]

CFNU research summary on COVID-19

Why does the CFNU recommend the precautionary principle, and what is it? We are learning more and more about COVID-19 each day, and many of the assumptions we made about COVID-19 just a few months ago have been proven wrong. The U.S. CDC guidance now recognizes that COVID-19 may be spread at close range through […]

Haug, N., Geyrhofer, L., et al. 2020. “Ranking the effectiveness of worldwide COVID-19 government interventions.” Nature Human Behaviour volume 4, pages 1303–1312 (2020) 16 November 2020

Assessing the effectiveness of non-pharmaceutical interventions (NPIs) to mitigate the spread of SARS-CoV-2 is critical to inform future preparedness response plans. Here we quantify the impact of 6,068 hierarchically coded NPIs implemented in 79 territories on the effective reproduction number, Rt, of COVID-19. We propose a modelling approach that combines four computational techniques merging statistical, inference and […]
