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.”
The study’s objective was to compare the source of moderate to vigorous physical activity (MVPA). There is a great variation amongst the population of 104 countries.

Different populations seem to be getting their MVPA from different sources.
Epidemics-Pandemic control is important. There are many lessons that can be learned. Furthermore, it is important to appreciate that not all events can be controlled the same.
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
Commrecially available sugary drinks, which are widely consumed in Western countries, might represent a modifiable risk factor for cancer prevention. These include 100% fruit juices were also positively associated with the risk of overall cancer.
