Would ID₅₀ and LD₅₀ Necessarily Be the Same for a Given

question 6

Multiple Choice

Would ID₅₀ and LD₅₀ necessarily be the same for a given virus? Why or why not?

• A)Yes,because the number of viruses that infect 50% of a test population should also kill 50% of that test population.
• B)No,because a virus may be highly infectious (very low ID₅₀ value)but only marginally lethal (very high LD₅₀ value).A prime example of this is the rhinovirus (common cold virus).
• C)No,because very few viruses are lethal,yet many are highly infectious.The two values should ALWAYS be different.
• D)Yes,because what we're actually describing here is infection/killing of individual CELLS,not of entire organisms.If a cell is infected,it will always be killed.
