Question
Which of these statements is correct in relation to COVID-19?Question 27Answera.A reduced inflammatory response is responsible for severe COVID-19.b.Patients may present with severe hypoxia but display no symptoms.c.The SARS-CoV-2 virus will ONLY will only ever infect cells in the lungs.d.SARS-CoV-2 virus infection in most cases will lead to death.e.Systemic organ damage occurs primarily due to thinning of capillary basement membranes.
Solution
The correct statement in relation to COVID-19 is:
b. Patients may present with severe hypoxia but display no symptoms.
Explanation:
a. It is incorrect because a severe form of COVID-19 is often associated with an overactive, not reduced, inflammatory response known as a cytokine storm.
c. This is incorrect because SARS-CoV-2 can infect cells in various parts of the body, not just the lungs. It enters cells via the ACE2 receptor, which is found in various tissues including the heart, kidneys, and intestines.
d. This is incorrect because most cases of SARS-CoV-2 infection do not lead to death. While the virus can be severe or fatal for some, many people experience mild symptoms or are asymptomatic.
e. This is incorrect because systemic organ damage in COVID-19 is primarily due to the body's inflammatory response to the virus, not due to thinning of capillary basement membranes.
