Sample QuestionA 1-year-old toddler is admitted to the hospital in February following an abrupt onset of vomiting followed by watery diarrhea accompanied by low-grade fever. On admission, the child appears somnolent, has a fever of 38.8C (101.8F). His pulse is 130/min, respiratory rate 36/min, blood pressure 100/60 mmHg, and decreased skin turgor. Blood tests reveal an elevated white blood cell count (15,000/L) with 75% polymorphonuclear leukocytes. A stool sample is sent to the microbiology lab for analysis. Results reveal watery stools with no mucus, blood, leukocytes or parasites. A rapid antigen test is positive for a naked, segmented, dsRNA virus, so no stool culture is required. The diarrhea suffered by this child can be partially attributed to a viral protein (rotavirus NSP4) that alters the permeability of intestinal epithelial cell tight junctions and inhibits the glucose-coupled Na+ transport of these same cells, thereby increasing osmotic gap. What best describes this virulence mechanism?

Sample QuestionWorking as an entomologist in Thailand, you are responsible for catching Aedes aegypti female mosquitoes in a study aimed at determining the prevalence of arthropod-borne viruses (arboviruses) in local mosquito populations. Results show that 6.5 % of female Aedes aegypti mosquitoes captured carried enveloped, spherical single-stranded, positive-sense RNA viruses about 50 nm in diameter. In this instance, Aedes aegypti female mosquitoes would serve as vector for which of the following diseases?
