A group of RNA viruses that can cause diseases such as SARS and COVID-19 is called what?

• A. Influenza
• B. Adenovirus
• C. Rhinovirus
• D. Coronavirus

Answer: (D)

Coronaviruses are a family of RNA viruses that can cause respiratory infections, including the diseases SARS and COVID-19. They have spike proteins that create a crown-like appearance and use specific receptors on human cells to enter them, with SARS-CoV-2 (the virus behind COVID-19) and SARS-CoV (behind SARS) being members of this family. Influenza is caused by an RNA virus but from a different family (orthomyxoviruses). Adenoviruses are DNA viruses, not RNA. Rhinoviruses are RNA viruses as well, but they primarily cause the common cold and are not responsible for SARS or COVID-19. So, the best answer is coronavirus.
