Biology of SARS-COV2

SARS-CoV-2, the virus responsible for COVID-19, is a novel coronavirus that primarily targets the respiratory system. Its distinctive spike proteins facilitate its entry into human cells, particularly those lining the airways. Once inside, the virus hijacks cellular machinery to replicate, triggering various immune responses and often leading to respiratory distress and other systemic symptoms.

  • SARS-CoV-2 is a contagious disease that causes severe acute respiratory syndrome (SARS) (Meo et al., 2021).
  • Symptoms of SARS-CoV-2 infection include fever, cough, shortness of breath, and body aches. The virus can sometimes lead to more severe illnesses such as pneumonia and acute respiratory distress syndrome (Umakanthan et al., 2020).
  • To prevent the spread of SARS-CoV-2, it is important to practice good hygiene, such as washing hands frequently and wearing a mask in public (Wang et al., 2021).
