Transmission, protection, and potential treatment options for COVID-19

Global challenges continue to be posed by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-driven novel coronavirus disease (COVID-19) pandemic. Researchers have been unable to find an effective vaccination or practical therapy choices despite extensive global research efforts. Therefore, the best strategy for limiting illness spread is infection prevention, early virus detection, and creation of effective treatment procedures. Current COVID-19 treatment options, prevention strategies, and routes of transmission are covered in this review. Although it had been predicted by early March 2019 that new coronavirus infections will arise, likely coming from Chinese bats, no worldwide preventive action was done. In early 2020, further information concerning the outbreak was finally made public by the National Health Commission of China after many cases of pneumonia with an unknown origin were noted at the end of 2019. The World Health Organization (WHO) initially referred to the disease-causing virus as "novel coronavirus 2019" (2019-nCoV), but the international committee of the Coronavirus Study Group (CSG) later renamed it "severe acute respiratory syndrome coronavirus 2" (SARS-CoV-2) and WHO referred to it as "coronavirus disease 2019" (COVID-19). The outbreak is believed to have started at the Hunan seafood market in Wuhan, China.
