What is total mass of human-infecting SARS-CoV-2 Covid-19 virus


If you took all the SARS-CoV-2, COVID-19, virii / virus particles that have infected all humans since the beginning of the outbreak in late 2019, what would be their total mass? Would they all fit in a shot glass? beer glass? wine cask? moonshine bathtub? brewery vat? Frank Sinatra's wine cellar?

(I'm curious and Googled for this but get a lot of unrelated stuff.)

Rough ballpark estimate: from few 100s of kilograms to maybe few 100s grams.

Reasoning: (Number of infected, N) / (viral load)×(average human size in milliliters)) × (mass of the virus) × number of time viruses replicate in humans.

N = 2-10 million, Viral load: 10^4 to 10^7 / mL so maybe 5x10^9 viruses per human at any time. The weigh of the virus is in the order of magnitude 1×10^−18 (100s attograms to femtogram)

To add to your question, what would the mass of virus actually appear like in terms of physical/optical properties?

This sounds like a Google interview question....

A shot glass of pure virus is an interesting concept. No matter how well vaccinated you might be, drinking it would overwhelm any possible response. Better yet, snort a line of it.
