Respiratory Syncytial Virus Infection
Exam 2026 Questions and Answers
"Define Respiratory Syncytial Virus (RSV) infection." - Correct answer-"RSV
infection is a contagious RNA virus that affects the respiratory tract, causing
illnesses ranging from mild upper respiratory infections to severe bronchiolitis and
pneumonia, particularly in infants, young children, the elderly, and
immunocompromised patients."
"Explain the transmission methods of RSV." - Correct answer-"RSV is usually
transmitted through respiratory droplets, direct contact, or contaminated surfaces."
"Describe the high-risk periods for RSV infection." - Correct answer-"There is a
high risk of RSV infection occurring during winter and early spring."
"Identify the major cause of hospitalization related to RSV." - Correct answer-
"RSV is a major cause of hospitalization in infants due to low respiratory tract
infections, especially in premature babies and patients with chronic lung disease."

, "What is the primary effect of RSV on the respiratory system?" - Correct answer-
"RSV primarily affects the respiratory epithelium, leading to inflammation and
mucus production."
"List the risk factors for severe RSV infection." - Correct answer-"Risk factors
include being a premature baby, being a neonate, having congenital lung or heart
disease, being elderly, and having chronic lung disease or neuromuscular
disorders."
"How does RSV affect premature babies specifically?" - Correct answer-
"Premature babies have underdeveloped lungs and weak immune systems, making
them particularly vulnerable to severe RSV infections."
"Explain the pathophysiology of RSV infection." - Correct answer-"RSV primarily
affects the lower respiratory tract, leading to bronchiolitis and pneumonia, causing
inflammation, airway obstruction, and impaired gas exchange due to excessive
mucus production and necrosis of respiratory epithelium."
"Describe the process of RSV infection at the cellular level." - Correct answer-
"RSV enters through respiratory droplets, infects nasopharyngeal and lower
respiratory tract epithelial cells, attaches to host cells via fusion and glycoproteins,
and replicates rapidly in the bronchiolar epithelium, leading to cell injury and
necrosis."
