Practice Questions (MCQs)
1. Consider the following statements regarding disease surveillance in India: 1. The National Centre for Disease Control (NCDC) is the nodal agency for disease surveillance and public health intelligence in India. 2. The Integrated Disease Surveillance Programme (IDSP) primarily relies on real-time social media data for early outbreak detection. 3. The recent initiative by NCDC to explore social media data aims to complement, rather than replace, traditional reporting systems. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is correct. NCDC is indeed the nodal agency for disease surveillance and public health intelligence in India. Statement 2 is incorrect. The Integrated Disease Surveillance Programme (IDSP), launched in 2004, is a state-based, decentralized surveillance system that primarily relies on data reported from health facilities (hospitals, labs, etc.) and not real-time social media data. Statement 3 is correct. The NCDC's exploration of social media data is an innovative approach intended to enhance and complement existing traditional surveillance methods, providing additional real-time insights, rather than completely replacing them.
2. With reference to the use of social media data for public health surveillance, consider the following statements: 1. Data collected from public social media platforms are inherently free from privacy concerns as they are publicly available. 2. The Digital Personal Data Protection Act, 2023, provides a framework for processing personal data, including data used for public health purposes, with certain obligations. 3. The 'digital divide' in India could lead to biased or incomplete disease pattern analysis when relying solely on social media data. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
Show Answer
Answer: B
Statement 1 is incorrect. Even publicly available data can raise significant privacy concerns when aggregated, analyzed, and used to infer patterns about individuals or groups, especially without explicit consent or robust anonymization. The context of use matters. Statement 2 is correct. The Digital Personal Data Protection Act, 2023, is India's comprehensive law governing the processing of personal data, which would apply to data used for public health purposes, imposing obligations on data fiduciaries. Statement 3 is correct. India's significant 'digital divide' means that a large portion of the population, particularly in rural or socio-economically disadvantaged areas, may not have access to social media. Relying solely on social media data would therefore provide a skewed or incomplete picture of disease patterns, leading to biased analysis.
3. In the context of leveraging technology for public health interventions in India, which of the following statements is/are correct? 1. Artificial Intelligence and Machine Learning can be utilized for predictive modeling of disease outbreaks and drug discovery. 2. Telemedicine services have significantly expanded access to healthcare, particularly in remote and underserved areas. 3. Blockchain technology is primarily used for securing financial transactions and has limited application in healthcare data management. Select the correct answer using the code given below:
- A.1 only
- B.2 only
- C.1 and 2 only
- D.1, 2 and 3
Show Answer
Answer: C
Statement 1 is correct. AI and ML are increasingly being used in public health for tasks like predicting disease outbreaks based on various data points (weather, travel, social media), identifying potential drug candidates, and personalizing treatment plans. Statement 2 is correct. Telemedicine has proven to be a game-changer, especially during the pandemic, by providing remote consultations and healthcare access, thereby bridging geographical gaps and serving underserved populations. Statement 3 is incorrect. While Blockchain is widely known for financial transactions, it has significant and growing applications in healthcare, including securing electronic health records, managing supply chains for pharmaceuticals, ensuring data integrity for clinical trials, and facilitating secure data sharing among healthcare providers. Its decentralized and immutable nature makes it ideal for secure data management.
