Two directly transmitted viral diseases have the same critical immunization threshold
(P) even though their effects on the host are different. Which of the following differences
between the two diseases could lead to the same critical immunization threshold?
oOne disease has a higher transmission rato and a longer recovery period than the other
One disease has a lower transmission rate and a longer recovery period than the other
O One disease has a lower transmission rate and a shorter recovery period than the other.
o For one disease, the recovery period is long: for the other, no one recovers
Answers
Answer:
One disease has a higher transmission rate and longer recovery period than the other
Explanation:
Longer recovery periods decrease the Ro value while higher transmission rates increase it, so it could even each other out
