INTRODUCTION: Ever since the first COVID-19 patient was diagnosed, we have gone through incredibly challenging periods worldwide. Nevertheless, these times have produced massive developments in the medical field with bursts of knowledge and discoveries.
CASE PRESENTATION: Our manuscript reports the case of a doctor-patient with two SARS-CoV-2 infections, who have been vaccinated in the interim. Daily lung ultrasound was performed for both infections showing pathological findings in the first period and no alterations in the second.
CONCLUSSION: Considering the emerging variants of SARS-CoV-2 and the diminished vaccine efficacy, this case enhances the importance of complementing the evaluation of COVID-19 patients with lung ultrasound. It helps to define diagnosis and guide treatment, enabling the prediction of severity and prognosis.
