Aroma diffuser, plastic bag offer inexpensive method to test fit of face masks at home ANI | Updated: Dec 16, 2020 18:04 IST
Cambridge [England], December 16 (ANI): Researchers have developed a way to use a simple home aroma diffuser to test whether N95 and other types of sealing masks, such as KN95 and FFP2 masks, are properly fitted, a result which could be used to help protect healthcare workers and the public from contracting or transmitting COVID-19.
The researchers, from the University of Cambridge, tested a variety of materials to construct a new inexpensive and reliable method for assessing the fit of masks. Commercial testing equipment has been in extremely short supply since the outbreak of the COVID-19 pandemic, forcing many healthcare institutions to abandon regular fit-testing of their staff.

In comparative terms, deaths from COVID-19 are currently about:
90% below annual fatalities from all causes.
7.7 times average annual fatalities from the flu.
70% above annual fatalities from accidents.
Although C-19 is a new disease and took its first reported life in the U.S. during late February, these comparisons may substantially overstate its deadliness. This is because fatalities from accidents, the flu, and other common causes of death occur in droves every year, and this is unlikely for C-19 because of the facts below.
Immunity
The primary reason why the flu kills tens of thousands of people every year is that the viruses that cause it mutate in ways that prevent humans from becoming immune to them. Per the Journal of Infectious Diseases, “All viruses mutate, but influenza remains highly unusual among infectious diseases” because it mutates very rapidly, and thus, “new vaccines are needed almost every year” to protect against it.
