When the COVID-19 pandemic took off in 2020, so too did questions over the effectiveness of wearing a face mask to prevent the spread of the virus. Now, four years later, what does the science say? In an interv
COVID-19ColoniesIncubationCorona virusAn experiment was conducted to compare the effectiveness of wearing a mask and not wearing a mask while also addressing concerns such as "will a wearing mask reduce the amount of bacteria spread?" This experiment was compiled over the course of thirteen days....
This aspect of mask wearing is especially important because it is estimated that at least 50% or more of transmissions are from persons who never develop symptoms or those who are in the presymptomatic phase of COVID-19 illness.1 In recent laboratory experiments, multilayer cloth masks were ...

of their positive test with a test-negative case–control (TNCC) design15. This has yielded estimates of the effectiveness of over 90% against Alpha and Delta variants. However, given that all individuals who are hospitalised for any reason in the UK are tested for COVID-19, and with the...
To understand the distinctive spreading behavior of COVID-19, which has been rarely encountered before, numerous researchers have attempted to examine it from both social epidemiology and biology perspectives. A widely used theoretical model is the compartmental model, which represents a population with...

There is currently limited data on the dura- tion of protection against severe disease. In this study, we assess the effectiveness of COVID-19 vaccines against hospitalisation in those testing positive by PCR for Omicron and Delta variants. In the past, we have done this using symptomatic ...
We urge for truth and transparency all the way through, even if this means that people can profit less from the vaccines' possibly substantial placebo-effect. The balance will eventually be positive.doi:10.13140/RG.2.2.34390.68166Jean-Luc Mommaerts...
