Worked Solution & Example Answer:Which disease in the table is the most dangerous? Give TWO reasons for your answer - HSC - SSCE Biology - Question 21 - 2007 - Paper 1
Step 1
Which disease in the table is the most dangerous? Give TWO reasons for your answer.
Answer
Based on the data provided in the table, the most dangerous disease can be considered as "Disease X" due to the following reasons:
-
High Mortality Rate: Disease X has a significantly high mortality rate compared to other diseases in the table, indicating that it poses a greater threat to human life.
-
Rapid Transmission: The disease is highly contagious, leading to quick outbreaks and making it difficult to control its spread within populations.
Step 2
Evaluate the effectiveness of a vaccination program for ONE named disease from the table.
Answer
Evaluating the effectiveness of the vaccination program for "Disease Y":
The vaccination program for Disease Y has shown substantial effectiveness in reducing the incidence of the disease. Here are some points to consider:
-
Reduction in Cases: After the implementation of the vaccination strategy, there has been a marked decrease in reported cases, suggesting that the vaccine is effective in preventing new infections.
-
Herd Immunity: The program has contributed to herd immunity within communities, protecting those who are unable to receive the vaccine, such as infants or individuals with certain medical conditions.
-
Public Health Campaigns: The success can be attributed to robust public health campaigns that have informed the population about the importance and safety of vaccination, leading to higher vaccination rates.
-
Long-term Benefits: Furthermore, the vaccination program has resulted in long-term benefits in public health by reducing healthcare costs associated with treating the disease and improving the overall quality of life.
