We might have heard about Einstein’s Famous quote on Gandhi. Few years ago, I discovered that the quote is from a book by Albert Einstein with Title “Essays in Humanism”

Mahatma Gandhi

A LEADER OF his people, unsupported by any outward authority: a politician
whose success rests not upon craft nor the mastery of technical devices, but
simply on the convincing power of his personality; a victorious fighter who
has always scorned the use of force; a man of wisdom and humility, armed
with resolve and inflexible consistency, who has devoted all his strength to
the up lifting of his people and the betterment of their lot; a man who has
confronted the brutality of Europe with the dignity of the simple human
being, and thus at all times risen superior.

Generations to come, it may be, will scarce believe that such a one as this
ever in flesh and blood walked upon this earth.

Six-months into pandemic there is a lot of settled knowledge about Coronavirus now. This medium article - The Most Likely Way You’ll Get Infected With Covid-19 covered it very well.

What we know

1. Surfaces don’t seem to matter as much as originally thought.

   1. SARS-CoV-2 does not spread through surfaces.

   2. No need to disinfect food, parcels, etc.

2. Close range droplets are the new leading theory and Aerosol transmission has gradually gained acceptance

   1. Coronavirus Spreads from infected person exhaling and non-infected inhaling.

   2. A tiny droplets of virus spread in air in trajectory less than 6 feet.

   3. Best way to prevent this - "Wear Mask".

Six months in, "Wearing Masks" is the most effective way to protect ourselves. Both to avoid the spread and also to protect ourselves from getting infected. That's it.

Incidentally, the first strong support for wearing mask as reducing infections came via statistical analysis by Jeremy Howard in the article from May 15 - Masks help stop the spread of coronavirus

Best way for us to fight the virus - "Wearing Mask".
