The COVID-19 pandemic has killed more than 400 thousand and infected more than 7 million people in the whole world as of 06/10/2020. Many open systems, such as educations, transportations, entertainments, sports or foods, have been completely or partially locked down in many regions of the world to prevent COVID-19 spreading. Therefore, how to reopen all of the open systems after the shutdown has become a world urgent issue. Evidences of COIVD-19 have showed: person-to-person transmission occurs among close contacts; virus droplets (or aerosols) play an important role in the transmission; people can prevent COVID-19 by measures of mask-wearing or maintaining social distancing. However, how these measures work to prevent COVID-19 is still not clear in a perspective of biomedical Infophysics. In this study, (1) we think the transmission of infection can be accomplished by real or virtual person; (2) we define a virtual person as ghost airflow, a term we coin to describe virus droplets (or aerosols) that are initially generated by human carriers and remain in the air to be transmitted. These ghost airflows are as dangerous as the real virus carriers particularly in enclosed (confined) environments; (3) we propose biomedical infophysical models (BMIPM) of filtering the ghost airflows by mask-wearing and maintaining social distancing, to help people to understand the filtering mechanisms and willingly follow the guidelines of preventing covid-19, and therefore to successfully reopen all of the open systems after the shutdowns (lockdowns) and (or) to avoid the shutdowns (lockdowns) in future epidemics or pandemics. Significantly, we compare the prevention efficiencies of COVID-19 between people who are accustomed and not accustomed to masks based on the published WHO, CDC or NHC pandemic data. The compared results support our models in this investigation. Coronaviruses easily survive and have high toxicity, in dirty, wet and cold environments, and the air pollution is linked with higher COVID-19 death rates. The dingy environments and air-conditioning, freezing systems sufficiently provide such necessary dirty, wet and cold conditions and polluted airflows to exacerbate the mortality rate of COVID-19. Therefore, we strongly suggest: to use air conditioners as less as possible, to turn the wind levels as low as possible and to clean (disinfecting) the air-conditioning systems (filters and channels) and environments as frequent as possible.

“…In social gatherings, in many cultures, it is common for people to share food and consume from the same plates and/or bowls. In order to prevent the spread of COVID-19 from person to person, some have suggested avoiding this practice [177]. Moreover, social gatherings, which are culturally more frequent in Ramadan, must be stopped and guidance for social and physical distancing must be followed as these measures are shown to be effective in reducing transmission of COVID-19 [178,179].…”

Ramadan 2020 and Beyond in the Midst of the COVID-19 Pandemic: Challenges and Scientific Evidence For Action

Background: Ramadan is a sacred month in Islam, which involves 29–30 days of dawn-till-dusk dry-fasting. Millions of Muslims observed Ramadan fasting (RF) this year in the midst of the COVID-19 pandemic. Certain ethnic groups worldwide, including Muslims, have been disproportionately affected by COVID-19, raising fears that fasting could bring additional health risks. This directly impacted on the current challenges faced by health professionals. The COVID-19 virus is expected to become seasonal. Therefore, the evidence presented in this review is valid beyond Ramadan as intermittent fasting is practiced more widely, irrespective of religion, throughout the year as a therapeutic and prophylactic means for several conditions. Methods: A wide range of literature databases were searched for the effects of RF and intermittent fasting on human health and then linked to COVID-19 impact to generate the evidence. Results: This review presents a body of evidence proving RF is safe and beneficial for healthy people who adopt a balanced diet, drink plenty of fluids, and engage in regular physical activity. Fasting reduces levels of pro-inflammatory cytokines (IL-1β and IL-6), which are associated with severe COVID-19. Furthermore, increased handwashing and hygiene during Ramadan may reduce infection risks. For some, social isolation, physical inactivity, reduced access to food and stress – linked to the pandemic – may minimize the benefits that is achieved during a “normal” Ramadan. Conclusions: RF during the COVID-19 pandemic is not a cause of concern for healthy people. However, people who are ill are exempt from fasting and should seek medical advice if they wish to fast. RF during the COVID-19 pandemic is a unique experience and future research will reveal its impact on human health.
