How many times can you get the virus?

A friend of mine has tested positive again. This is her 6th time having it, and her mom has had it 4 times. She lost her step dad from it too. She wanted to know if she set a record or if people have had it more times.

She also has some long Covid symptoms too but we’re not sure.

I’ve had it twice, and still have issues like smelling things and taste.
