Since the global pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of a coronavirus disease 2019 (COVID-19) infection started, millions of people globally have become infected. It must not be forgotten that thousands of those affected are commercial or recreational divers. A severe COVID-19 seriously affects the respiratory system and the pulmonary parenchyma but it may also involve the cardiovascular and the blood coagulation system. For this reason, many divers and hyperbaric medicine specialists are becoming increasingly concerned about a diver's ability to safely return to diving after a SARS-CoV-2 infection. The article presents current guidelines for diving fitness health assessment after a COVID-19 both for active and prospective divers, with particular emphasis on the types of diagnostic procedures and tests to be performed in cases of asymptomatic infection with SARS-CoV-2 as well as in patients who have recovered from a symptomatic COVID-19.
