Introduction:
There now exist preventive and curative treatments available for both early and advanced stages of COVID-19 management.
Current Knowledge:
Antibiotics have no place in the initial therapeutic management of Sars-Cov-2 pneumonia. On the other hand, corticosteroids are recommended for patients requiring oxygen therapy≥2L/min. According to the latest recommendations, nirmatrelvir/ritonavir is indicated as an early treatment for adults not requiring oxygen therapy but at high risk of developing a severe form of COVID-19. In case of contraindication, remdesivir is an alternative therapy.
Perspectives:
Although there is no indication for convalescent plasma outside of clinical trials, it seems promising for immunocompromised patients, particularly those with B lymphopenia. It is noteworthy that currently, with the predominance of the Omicron XBB.1.5 variant, monoclonal antibodies are no longer recommended as therapy except for sotrovimab, which still has partial efficacy and could be considered after expert opinion as salvage therapy in a previously well-established program.
Conclusion:
Despite the evolution of variants, antivirals still appear to have activity and remain the first-line treatment for patients, in addition to vaccination.
