100% CORRECT ANSWERS | LATEST
VERSION 2025/2026.
"Define Respiratory Syncytial Virus (RSV) infection." - ANS "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." - ANS "RSV is usually transmitted through
respiratory droplets, direct contact, or contaminated surfaces."
"Describe the high-risk periods for RSV infection." - ANS "There is a high risk of RSV infection
occurring during winter and early spring."
"Identify the major cause of hospitalization related to RSV." - ANS "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?" - ANS "RSV primarily affects
the respiratory epithelium, leading to inflammation and mucus production."

, "List the risk factors for severe RSV infection." - ANS "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?" - ANS "Premature babies have
underdeveloped lungs and weak immune systems, making them particularly vulnerable to
severe RSV infections."
"Explain the pathophysiology of RSV infection." - ANS "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." - ANS "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."
"What role do cytokines play in RSV infection?" - ANS "Cytokines cause inflammation, fever,
and mucus production as part of the immune response activated by RSV infection."
"How does RSV infection lead to airway damage?" - ANS "Airway damage occurs due to
necrosis of epithelial cells, which slough infected cells into the bronchioles, causing
inflammation and worsening airway swelling."
"Identify factors that increase the risk of RSV transmission." - ANS "Exposure to crowded
places, smoking, and poor hygiene can increase the risk of RSV transmission."
"Explain the impact of neutrophil and monocyte infiltration during RSV infection." -
ANS "Neutrophil and monocyte infiltration during RSV infection worsens airway swelling and
contributes to the inflammatory response."
