Though despite a growing number of people coping with long COVID, not much is known about why symptoms persist after the virus passes.

“Nail polish, coffee, fresh-cut grass — they all have a similar rotten smell,” Jill Ramos said.

Ramos had COVID-19 last September, despite following state and county masking guidance. Since then, the smell of fresh-cut grass is now more of a sewer smell to her.

Ramos has had distorted smell and taste since a week after her initial COVID-19 symptom onset.

The CDC sites a wide variety of long COVID symptoms including:

  • Tiredness or fatigue that interferes with daily life
  • Symptoms that get worse after physical or mental effort
  • Fever
  • Difficulty breathing or shortness of breath
  • Cough
  • Chest pain
  • Fast-beating or pounding heart (also known as heart palpitations)
  • Difficulty thinking or concentrating
  • Headache
  • Sleep problems
  • Dizziness when you stand up (lightheadedness)
  • Pins-and-needles feelings
  • Change in smell or taste
  • Depression or anxiety
  • Diarrhea
  • Stomach pain
  • Joint or muscle pain
  • Rash
  • Changes in menstrual cycles
