How does it actually feel having Covid 19? Has anyone had it? Some say its just like the flu?

Around 45% of people who get it have no symptoms at all.
Another 45% get a fever, bad cough and loss of taste.
Around 8% get viral pneumonia which usually requires hospital treatment.
The other 2% die.
The proportions are similar to seasonal flu.  The difference is that covid-19 is considerably more infectious and as yet there is no cure or vaccine.  Without a cure or vaccine, the eventual US death toll will be around 800,000.

Depends on the person, for some there are no symptoms for other they end up on a ventilator.  There is a range between that some people just have a loss of taste/smell some people describe it as breathing at altitude.  Some its just like flu/cold.

There is no 100% description of symptoms its different for different people.
