Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in
China, affecting millions of peoples worldwide, and was declared as a global health
emergency by the World Health Organization (WHO). This infection is extremely
transmittable from humans to humans due to its long incubation period (as compared to
other viruses of the same category), which results in asymptomatic carriers. The
complete knowledge regarding this virus is still unclear and various studies are being
conducted worldwide. Till now, no vaccines or specific drugs are available for its
prevention and treatment. However, various classes of drugs are repurposed for their
treatment and many new drugs and vaccines are under development. This chapter
