Insights
Coronaviruses cause illnesses from colds to severe diseases like SARS and MERS. A new strain, SARS-CoV-2, causes COVID-19, a global pandemic with no specific approved medication yet.
Area of Science:
- Virology
- Infectious Diseases
- Public Health
Background:
- Coronaviruses encompass a range of viruses causing illnesses from common colds to severe respiratory syndromes (SARS, MERS).
- A novel coronavirus, SARS-CoV-2, emerged in Wuhan, China, in December 2019, leading to the COVID-19 pandemic.
- The COVID-19 pandemic has resulted in millions of confirmed cases and significant global mortality.
Purpose of the Study:
- To review the current understanding of COVID-19.
- To summarize available medications and potential treatment options for COVID-19.
Main Methods:
- Literature review of existing knowledge on COVID-19.
- Analysis of current and investigational therapeutic agents.
Main Results:
- No specific medication is currently recommended for COVID-19 treatment.
- Antiviral drug Favilavir is approved in China for COVID-19 symptom treatment.
- Chloroquine and hydroxychloroquine are under investigation by the FDA for COVID-19 treatment.
Conclusions:
- The review highlights the urgent need for effective COVID-19 treatments.
- Existing drugs like Favilavir, chloroquine, and hydroxychloroquine show potential but require further investigation.
- Development of a COVID-19 vaccine is ongoing, with clinical trials anticipated later in the year.
Abstract:
Coronaviruses are a large group of viruses known to cause illnesses that vary between the common cold and more severe diseases to include severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS). A novel coronavirus was identified in December 2019 in Wuhan city, Hubei province, China. This virus represents a new strain that has not been previously identified in humans. The virus is now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the resulting disease is called coronavirus disease 2019 (COVID-19). The World Health Organization (WHO) declared the novel coronavirus outbreak a global pandemic in March 2020. Despite rigorous global containment and quarantine efforts, the incidence of COVID-19 continues to rise, with more than 1,948,617 laboratory-confirmed cases and over 121,846 deaths worldwide. Currently, no specific medication is recommended to treat COVID-19 patients. However, governments and pharmaceutical companies are struggling to quickly find an effective drug to defeat the coronavirus. In the current review, we summarize the existing state of knowledge about COVID-19, available medications, and treatment options. Favilavir is an antiviral drug that is approved in Japan for common influenza treatment and is now approved to treat symptoms of COVID-19 in China. Moreover, Chloroquine and hydroxychloroquine, drugs used to treat malaria and arthritis, respectively, were recommended by the National Health Commission of the People's Republic of China for treatment of COVID-19. Presently, chloroquine and hydroxychloroquine are under investigation by the US Food and Drug Administration (FDA) as a treatment for COVID-19. The first COVID-19 vaccine is not expected to be ready for clinical trials before the end of the year.
