To date, research has shown that the viruses that have been identified and isolated can range in diameter size from 20 nm to as large as 500 nm. Aside from spherical virus particles like SARS-CoV

The virus that causes COVID-19 is under 0.1 micrometer in diameter. (A micrometer (µm) is one one-thousandth of a millimeter.) The holes in masks may be five to 200 micrometers. (5,000 nm to 200,000 nm) in diameter. It is counter-intuitive that masks can be useful in this setting. 

COVID-19 virus is under 0.1 micrometer (0.0001 mm)
Masks holes range 5 to 200 micrometer (0.005mm - 0.2mm)

COVID-19 virus is under 100 nanometer
Masks holes range 5 to 200,000 nanometer

1 millimeter (mm) = 1000 micrometers (μm)
0.1 micrometer = 0.0001 mm
1 millimeter = 1,000,000 nm

(1 micrometer = 1000 nanometer)

0.1 micrometer = 100 nanometer

200 micrometers = 200,000 nanometer

PCR test cannot detect free infectious viruses. PCR Test picks up on genetic material. SARS Cov2 (does not exist).
The RT-PCR test does not identify/detect the Covid-19 virus. What it detects are fragments of several viruses.

RT-PCR test is a real-time (reverse transcription) polymerase chain reaction (RT-PCR)

1. PCR tests are meaningless as a diagnostic tool
2. PCR is picking up fragments of RNA or DNA - which can be amplified to find small traces which can be found in all humans.
UK amplifies at 45 cycles
3. (99.74%) of infected cases survive
The reported infection rate us increasing but the death rate us flat lined
4. (0.26) actually died - but if you look at the Comorbidity ( comorbidity is the presence of one or more additional conditions) those people had secondary illnesses
5. (99.9%) of the world’s population have already been exposed to COVID19. It no different to a common cold.
6. It all comes down to mandatory vaccines
The genetic primers and popes used to identity SARS Cov2 in the PCR Test, do not target can not identify any

The ability of ethylene oxide to damage DNA makes it an effective sterilizing agent but also accounts for its cancer-causing activity
