Understanding and implementing alternative solutions to address the COVID-19 pandemic in the sense of public health emergencies

摘要

The Coronavirus disease (COVID-19) caused by the novel SARS-CoV-2 coronavirus has spread from China and quickly transmitted to most other countries around the world. The World Health Organization announced COVID-19 as a pandemic that is spreading steadily and soon in most states. Coronavirus genomic characterization showed that it most closely resembled another bat-origin beta-coronavirus. Coronavirus has the largest genome of viruses that have RNA. Spike (S) glycoprotein is present in the virus and is responsible for virus entry into the host cell. COVID-19 can spread through the droplet, direct contact, and aerosol transmission in humans. It can remain in the environment and exists on plastic and steel for the longest time, making it a dangerous and contagious disease that can kill other individuals. The virus has an incubation time of 2 to 14 days. Confirmed cases of COVID-19 have evolved exponentially in the world. Possible preventive steps for disease control include more mask use, hand sanitization, and social distancing. There is no antiviral therapy and only symptomatic care. Many inhibitors of HIV protease and other antimalarial drugs have tested. There is currently no vaccine available for COVID-19 prevention, though others are available in clinical trials. Scientists often use spike proteins for vaccine production. Research is needed to develop a new innovative vaccine and targeted medicine, which will meet people’s demands.
