The distributed nature of Delhi's public health infrastructure with commitment to universal healthcare coverage allows for capacity and flexibility. Prudent resource allocation, conscientious human resource management and private-public-civil society partnership can work wonders! 
There are 100 containment zones in Delhi now (with a few de-contained formally). Only 5 lakh people out of 2 crore population and less than 1% area has been put into containment with essential relief at doorstep. Ensures surgical strikes on Corona without at scale inconvenience.
One of the critical aspects of Operation SHIELD in containment zones is door to door checks on citizens treated as probabilistic patients and enquired about general well-being and specific symptoms. This map shows clustering of health checks by Revenue Department across the city.
Quite different from some states where healthy humans have been intentionally tested, the Health Department of GNCTD has jumped into containment zones with PCR tests to ensure accurate clinical patient mapping and public health mapping of containment zones. Heroic truly imo.
The Health Department is rapidly increasing its network of Covid Testing Centers, Covid Care Centers and Covid Health Centers and Covid Designated Hospitals based on needs basis. The Mohalla Clinics, Polyclinics and other Hospitals continue to serve public for non-Covid purposes.
Data systems aren't great rn which are being constantly improved through diligent human endeavour and IT systems are being built by conscientious engineers and scientists in parallel but these measures have ensured low doubling rate, high recovery rate and low fatality rates.
