Wash your hands or do not wash your hands when you eat

IMO, it's all conditions dependent.

A Bacteria is a  single-celled lifeform that can self replicate while a Virus is just a chunk of RNA or DNA that has to hijack a hosts cells to replicate

AH, thank you.

Viruses are very small. They are a small collection of molecules. Most of them are made of a single strand of RNA that bends at some point, it does 180 ° and comes back and forms some bonding with the same RNA strand. This helps to stabilize the RNA strand.
I think it also does a helix.
On top of that, there is a bunch of protein molecules that cover this RNA strand. This also helps to stabilize the RNA. I think the proteins are called capsids.
So, I guesstimate that the thickness of this type of virus is 50 to 100 atoms. This would mean that the thickness is 4 to 8 nm.
You can't see a single virus with an optical microscope bc of that.
They use an electron microscope. I think they mostly use a Scanning Electron Microscope.

There are some rare viruses that are DNA based instead of RNA.

Some viruses are bubble shaped, like this COVID-19. I would have to read about it sometime.

There is another thing called a viroids. These don’t have the protein cover.

Some viruses can infect a bacteria. Some can infect plants. I think they are mostly specific. A virus might work in a certain plant but not others.

Bacteria are gigantic compared to a virus and can be seen under an optical microscope.
Viruses are technically not alive (the biological definition of alive) but they categories them in biology since they play a big role there.

WARNING: There might be some errors. I'm not a biology pro.

 Perhaps you're not a biology pro, but you managed to confuse me.

The human virus self replicates.

Does nobody realise the difference between viruses and bacteria?

Of course. Viruses are tiny invisible monsters that make my computer stop working, while bacteria are generally much bigger, wear read hats, and carry signs that say things like ‘Trump Won!’.

short answer, No. 
long answer, He's not saying don't wash, He's saying what goes in comes out of as poop, it's the poop that comes out of the mouth (that comes from the heart) they should be worried about. Washing hands isn't what you need to be worried about.

That was my take on it - he was saying to be more concerned with spiritual defilement. I have to say that, while not generally a fan of Jesus, he handled the Pharisees pretty well.

They could not tackle Jesus mentally.

There is an interesting show down happening between these 2 sects.
