Researchers have identified cells in the lungs, nasal passages, and intestines that are more susceptible to SARS-CoV-2. Secretory cells in the nasal passages have RNA for proteins that COVID-19 targets. The virus may have mutated to exploit interferon, proteins released to fight infections. Enterocytes in the intestine, responsible for nutrient absorption, also express these RNAs, making them vulnerable to the virus.

Which cells in the nasal passages are identified as having RNA for proteins targeted by SARS-CoV-2?

• Ciliated cells

• Secretory cells

• Basal cells

• Goblet cells

What is the role of interferons in the context of viral infections?

• They are carbohydrates that trap viruses.

• They are enzymes that digest viruses.

• They are proteins that help cells fight viruses.

• They are lipids that block viral entry.

How might the coronavirus have adapted to enhance its infectivity according to the research?

• By increasing its size

• By reducing its replication rate

• By mutating to exploit interferons

• By changing its color

What is the significance of enterocytes in the study of COVID-19 susceptibility?

• They express RNA for proteins targeted by the virus.

• They are unaffected by the virus.

• They produce antibodies against the virus.

• They are immune cells that destroy the virus.

Which part of the body is NOT mentioned as being susceptible to SARS-CoV-2 in the transcript?

• Heart

• Intestines

• Nasal passages

• Lungs
