With this correspondence, we would like to briefly outline a practical perspective about a possible integrative and effective management in spa settings of COVID-19 long-term sequelae, with a keen focus on post-infective lung damage and fibrosis, which is expected to become epidemiologically relevant in the general population. In order to outline a standard/baseline model of care, we think that it can be useful to refer to already existing rehabilitative plans with a long-standing tradition in Italy, such as those ones prescribed for work-related respiratory diseases like pneumoconiosis, in which long-term outcomes share some clinical characteristics with post-infective lung fibrosis. Such programs include diagnostic procedures (spirometry, ECG, blood tests) and treatments like respiratory physio-kinesiotherapy and postural drainage of the lungs; mechanical pulmonary ventilation for rehabilitative purposes, with or without drugs, along with standard medical and, when required, oxygen therapy; inhalation therapies with mineral waters; physical activity and psychological support. In conclusion, we believe that spa facilities can be a proper setting for respiratory rehabilitation and that already existing programs employed in occupational medicine can be a good starting point to plan rehabilitative strategies for post-COVID-19 patients. In particular, health spa centers can be useful not only to offer tailored programs of physical rehabilitation but also to provide patients with a psychologically supportive and health-promoting environment. Further studies on the topic are advised to properly assess and quantify with adequate outcome measurements the beneficial effect of a spa-based rehabilitative program in post-COVID-19 patients.
