“A greater proportion of vitamin D-deficient individuals with SARS-CoV-2 infection turned SARS-CoV-2 RNA negative with a significant decrease in fibrinogen on high-dose cholecalciferol supplementation.”
to paraphrase the authors:
“If vitamin D does, in fact, reduce the severity of COVID-19 then supplements would offer a relatively easy option to decrease the impact of the pandemic.”
It appears that one of the reasons that we have not been able to control the Covid-19 epidemic in the US is because we move too much. If we just stop traveling and socializing and wear a mask, we can ( and should have been able to) curb the exponential growth and spread of the virus. As of the publication of Blog, there are over 246,000 deaths in the US due to the Coronavirus.
Lancet Infection disease, Published a study:
“Association between mobility patterns and COVID-19 transmission in the USA: a mathematical modeling study.”
It provides additional information on how social distancing is s important in the control of this very deadly and real epidemic.
The information of how safe we need to maintain to avoid COVID-19 transmission needs to be studied in detail.
Eventhough virus RNA was found on surfaces, none were thought to be able to transmit disease.
The larger droplets traveled farther compared to the smaller droplets. This was due to the increase drag on the smaller droplets.
“Breathing out, singing, coughitng and sneezing generated warm moisr high momentum dropplets. These travel faster that the typical backgrund air ventilation flow.”
Risk of SARS-CoV-2 transmission from asymptomatic people in different settings and for different occupation times, venting, and crowding levels (ignoring variation in susceptibility and viral shedding rates). Face covering refers to those for the general population and not high grade respirators. The grades are indicative of qualitative relative risk and do not represent a quantitative measure. Other factors not presented in these tables may also need to be taken into account when considering transmission risk, including viral load of an infected person and people’s susceptibility to infection. Coughing or sneezing, even if these are due to irritation or allergies while asymptomatic, would exacerbate risk of exposure across an indoor space, regardless of ventilation
