Since the first reported cases of the novel coronavirus, several support groups have emerged on Facebook consisting of thousands of members calling themselves “long haul survivors,” reporting COVID-19 symptoms that they say have lasted for months.

“Today is day 93,” said Amy Watson, a preschool teacher who lives in Portland, Oregon as she shared a photograph of her thermometer that read 100.3 on June 18. She first tested positive for COVID-19 on April 11, after falling ill with flu-like symptoms in mid-March.

Watson said she has had a persistent fever for nearly three months now, along with a handful of other disconcerting symptoms.
