Explanation: The 'Ghar ghar nigrani' app was a significant initiative launched by the Punjab government to combat the spread of the COVID-19 pandemic. The app was designed to facilitate house-to-house surveillance, ensuring that every household in the state was surveyed for potential cases of the virus. This approach aimed to enhance the early detection and containment of the virus, thereby reducing its spread.
The app was launched through a video conference, highlighting the use of technology in public health measures. The initiative was part of a broader strategy to manage the pandemic effectively, leveraging digital tools to support health workers and officials in their efforts to monitor and control the virus.
Punjab, as a state, faced significant challenges during the pandemic, and the 'Ghar ghar nigrani' app was one of the measures taken to address these challenges. The app allowed for systematic and efficient surveillance, which is crucial in managing a highly contagious virus like COVID-19. By ensuring that every household was surveyed, the app helped in identifying and isolating cases early, which is essential in preventing the spread of the virus.
It is important to note that while Punjab launched this specific app, other states in India also implemented various measures to manage the pandemic. However, the 'Ghar ghar nigrani' app was a unique initiative by Punjab, making it the correct answer to the question.
