STUDY: Adult patients suffering complains 2 months after non-critical COVID-19 bouts

To describe the clinical evolution and predictors of symptom persistence during 2-month follow-up in adults with non-critical COVID-19.

Descriptive clinical follow-up (days 7, 30 [D30] and 60 [D60]) of 150 patients with non-critical COVID-19 confirmed by RT-PCR at Tours University Hospital from March 17 to June 3, 2020, including demographic, clinical and laboratory data collected from the electronic medical records and by phone call. Persisting symptoms were defined by the presence at D30 or D60 of at least one of the following: weight loss ≥ 5%, severe dyspnea or asthenia, chest pain, palpitations, anosmia/ageusia, headache, cutaneous signs, arthralgia, myalgia, digestive disorders, fever or sick leave.

At D30, 68% (n=103/150) of patients presented at least one symptom and 66% (n=86/130) at D60, mainly anosmia/ageusia: (59% (n=89/150) at symptom onset, 28% (n=40/150) at D30 and 23% (n=29/130) at D60). Dyspnea concerned 36.7% (n=55/150) patients at D30 and 30% (n=39/130) at D60. Half of the patients (n=74/150) at D30 and 40% (n=52/130) at D60 reported asthenia. Persistent symptoms at D60 were significantly associated with age 40 to 60 years old, hospital admission and abnormal auscultation at symptom onset. At D30, severe COVID-19 and/or dyspnea at symptom onset were additional factors associated with persistent symptoms.

Up to 2 months after symptom onset, two thirds of adults with non-critical COVID-19 had complaints, mainly anosmia/ageusia, dyspnea or asthenia. A prolonged medical follow-up of patients with COVID-19 seems essential, whatever the initial clinical presentation.
