Treatments for people with early COVID-19 infection is an urgent research focus

Despite experiencing only mild symptoms early in infection, many COVID-19 patients progress to severe disease that leads to hospitalization. Some also will experience lengthy recoveries and develop long-lasting fatigue, mental impairment and problems with heart and lung function.

While several treatments such as remdesivir and dexamethasone are either available or in development for severe COVID-19, interventions that can be administered early during the course of infection to prevent disease progression and longer-term complications are urgently needed.

Studies are underway to assess whether existing antivirals can be repurposed for early treatment. Scientists also are exploring the effectiveness of early treatment with therapies that specifically target SARS-CoV-2, such as convalescent plasma and monoclonal antibodies. Investigators also are exploring strategies to deliver therapies by alternative routes than by intravenous infusion, such as by inhalation or intramuscular injection.

Continued research is needed to refine current treatment candidates and develop new drugs, and treatments will need to be administered easily and made available widely at low cost, according to the authors.

The article also highlights the need to design novel antiviral treatment approaches akin to successful efforts for hepatitis C virus and HIV. Such approaches could be helpful against future emergent viruses as well.

The article says robust support from the medical community and public is needed to ensure the success of these critical areas of research.
