The 26-year-old competed in the 4×100-meter relay event at the 2015 World Championships in Beijing, at the 2016 Summer Olympics in Rio, and at the 2017 World Championships in London.


On December 22 I got my booster vaccination because I didn’t want to struggle with this when the season started. I was told that it was safer to get Pfizer (even though I had Moderna the first time) to avoid cardiac side effects.

On December 27 I felt a tightness in the chest and started feeling dizzy while walking up the stairs. This happened a few more times until I decided to check with a cardiologist who diagnosed me with pericarditis (inflammation of the thin membrane surrounding the heart).

I am now not allowed to get my heart rate up for a few weeks to allow my heart to rest and heal from the inflammation.

Atcho was born in Lausanne, Switzerland, on June 1, 1995. She stands five feet and 11 inches.
