Theo Huot de Saint-Albin was a 9-year-old elementary school student when he first contracted COVID-19 in July 2020, near the start of the coronavirus pandemic. Four years later, as much of the world has moved on from the pandemic and resumed normal life, Theo, now nearly a teenager, is still battling the effects of long COVID. Over the past four years, Theo has contracted COVID-19 a total of three times, and each case has been mild.
