Two directly transmitted viral diseases have the same basic reproduction number (R), even though their dynamics are different. Which of the following differences between the two diseases could lead to the same basic reproduction number? ⦿One disease has a higher transmission rate and a longer infectious period than the other. ⦿One disease has a lower transmission rate and a longer infectious period than the other ⦿One disease has a lower transmission rate and a shorter infectious period than the other. ⦿For one disease, the infectious period is long, for the other, no one recovers. Q6.6. Imagine that a new, deadly coronavirus arises and starts a global pandemic. Experts are worried because the disease spreads easily, having a basic reproductive number, R., of 5. The good news is that an effective vaccine is quickly developed.What minimum proportion of the population,,, would need to be vaccinated to ensure that the disease can no longer spread?Round your answer to two decimal places.

Final answer:

Two directly transmitted viral diseases can have the same basic reproduction number (R) even though their dynamics are different if one disease has a lower transmission rate and a longer infectious period than the other.

Step-by-step explanation:

Two directly transmitted viral diseases can have the same basic reproduction number (R) even though their dynamics are different if one disease has a lower transmission rate and a longer infectious period than the other. This means that even though the disease spreads at a slower rate, the longer infectious period compensates for it and leads to the same basic reproduction number as the disease with a higher transmission rate and shorter infectious period.
