Abstract
COVID-19 has now become a global epidemic, prevailing over 213 countries
of the world including Pakistan. To date, there have been more than
12000 cases and above 220 deaths reported in Pakistan. The outbreak is
caused by a β-coronavirus called SARS-CoV-2, similar in characteristics
to the SARS and MERS-CoV. It shows symptoms like pneumonia and may lead
to death. Despite lockdown and possible isolation system, it is
spreading rapidly. Lack of precautionary measures, specific vaccine and
delayed diagnosis may be the major reasons for its spread. Several
researches on COVID-19 have described its various features to extend its
knowledge in order to help the scientific world in preparation of
vaccine. Current review aimed to cover all essential data such as
clinical characteristics, pathology, detailed morphology and structure,
antigenicity of COVID-19 virus, role of structural proteins in
anti-viral drug development and possible treatments being used. This
manuscript would be helpful to select the best possible treatment
depending on the availability and condition of the patient. Moreover,
further research is needed for assistance in designing a virus-specific
drug or vaccine.
