Why Dr. Harsh Vardhan's plan to handle COVID seems to be working

[Authored by: Mandar Garge, Apr 14, 2020]


This is an apolitical account of how Dr. Harsh Vardhan, the Union Health Minister is steadfastly steering India through the COVID19 crisis. 

I have quoted studies and articles from external (non-governmental) private health agencies to highlight the fact that India's strategy of handling COVID seems to be working under Harsh Vardhan's leadership.

While we all guess, contemplate, admire or criticize the government's handling of the crisis, it is important to bring to everyone's notice how this farsighted leader is working relentlessly to keep India two steps ahead of the COVID’s proliferation.


While PM Modi and his other ministers may be making economic, financial and administrative decisions during this crisis, they have left the medical and health related decisions to this one man who carries immense grasp of India's public health, its handling of mass immunization programs as well as the administrative challenges associated with such mass immunization activities.

National and State level health ministries work collectively, but the union health minister drives the overall plan and strategy to fight the virus.

I must mention that at this juncture the health ministers and departments of all state governments are working closely with the Union health minister and health officers. However Dr. Harsh Vardhan is in the driver's seat in the war against Corona. All key decisions at the national level, that you have been reading about India's rapid response to COVID, the passengers screening and quarantine in the very early stages followed by the lockdown are all his decisions, all coming out of his wisdom, farsightedness and vision combined with experience. His team then issues directives to state level health machinery to follow certain norms, be it about COVID reporting, medical preparations, testing the masses, identifying clusters and deciding the high level approach of weeding out the disease.

Evaluation the impact of the India lock-down:
Look at the following graph, published & updated daily by Shamika Ravi, a Sr. Fellow of the Governance Studies Program at the Brookings Institution Washington D.C:

This study measures the spread of Corona in terms of its rate of doubling rather than the absolute number of cases found. Going by this count, it seems that "the curve has started flattening".
  • March 12, India's count of COVID-19 cases was doubling every 3 days.
  • March 23, the count of COVID-19s was doubling every 5 days (flattening had started). This was before the lockdown.
  • March 29 -- doubling every 4 days -- a setback that can be attributed to Tablighi conclave aftereffects.
  • April 06 -- doubling every 6 days. The lockdown had started showing a positive impact.
  • April 13, the numbers were doubling every 7 days -- flattening had picked up further.
The research estimates that without the lockdown the positives would have been more than 67,052, as against the real count of April 13th of 10,453 (a 541% higher rate). Institute of Mathematical Studies (IMS) in Chennai had also estimated that without the lockdown, by the COVID count by mid-April would be have been 35,000 at a minimum.
The lockdown has surely worked. Of course, the testing levels in India are around 190,000, but one can assume, based on the sampling, the trend (proportion) will be consistent across a larger population.

Yes, indeed 10,815 (India count as of 14th April 2020, with 353 deaths) is a large number, but in an enormously populated country like India with enormous population density, this is really a small number, thanks to the strategy and approach taken by Dr. Harsh Vardhan. 10,000 as against 60,000 is a Great news. Compare this with 5.3 Lakh positives in the US with > 20,500 deaths.

The Basic Reproduction Number (R0)
The R0 (R-naught) number (Reproduction Number) is a mathematical term that indicates how contagious an infectious disease is. It’s a number that indicates how many people can an infected person infect. E.g., R0 number of 10 means one infected person can infect 10 other persons. An R0 of below 1, renders the spread of infection ineffective.

The R0 number of COVID-19 in India is improving.
  • Mid-March: 1.7
  • March 23: ICMR had estimated it to be 4. This is where the farsightedness of Harsh Vardhan must have prompted him to go into an immediate 21-day lockdown starting 25th March.
  • 6th April: 1.83
  • 11th April: 1.55
  • 18th April -- awaited. 
The central Govt. will then decide whether to relax the lockdown beyond 20th April or not (that's why PM Modi's staggered approach - which may ease the lockdown in low or zero impact areas but continue to keep the hotspot areas sealed. It would be mix of lockdown and limited economic activities.

The Health Ministry’s Approach:
The approach his ministry has taken is to stay two steps ahead of the coronavirus growth curve. The ministry feels that they have put in place a good amount of measures to be ready to tackle the rising cases of COVID.

The first goal of the Lockdown was not to contain and end COVID altogether, but to "Flatten the curve" by breaking the chain of transmission. The goal was to severely suppress the spread of the disease by as much as possible avoiding the outbreak of Community transmission (that is when Virus is all over, on surfaces in public places). Well such a suppression refrains the population from developing herd immunity to the virus, but the transmission rate is expected to be much lower after the lockdown is removed.

The second goal is to meticulously study daily growth, extrapolate the number of positives at the end of lockdown and aggressively prepare for handing the outbreak based on the estimates. Buy time to prepare and setup the medical facilities, spaces, beds, trained staff to handle that anticipated outbreak. The immunity of people will grow as well, but at its own pace.

An interesting report in New York Times by Dr. Faheem Younus, MD at University College Hospital of Maryland, USA outlined the “hospitalization rate” and “fatalities rate” in New York, the new epicentre of COVID-19 across different age groups. See a graphic from his tweet below:


So, the trend in the worst impacted place in the world shows that average hospitalization rate is less than 8 per 100,000 people up to age of 65, with the highest at 17 per 100,000 for ages above 80.
Today India has 10,815 positives. So, going by NYC estimates, very small number needs hospitalization. Even if India were to hospitalize all 10,000, the health ministry has announced that it is ready with 25,000 beds. And they are constantly increasing the following every day:
  • Number of beds
  • Quarantine facilities
  • Trained medical staff
  • Testing Kits & medical equipment
  • Medical supplies
And this is what it means by staying two steps ahead of the coronavirus growth curve.
One important decision that Dr. Harsh Vardhan took is that he followed the ICMR when most world leaders were looking at WHO. His team is also constantly following important medical and health bodies countries with infections and observing what has worked and what hasn't in those countries.

A little bit about Dr. Harsh Vardhan:

Harsh Vardhan, born in Delhi, graduated with a Bachelor of Medicine, Bachelor of Surgery in 1979. He did his Master of Surgery in 1983. He won an election in Delhi in 1994 and became the State Minister of Health the Delhi government, during which he oversaw successful implementation of the pilot project of the Pulse Polio Program which mass immunized 1 million children in Delhi. Then In 1995 he led a similar program of similar nature immunizing 88 million children, but across the entire Nation. WHO declared India polio-free in 2014.

His understanding of Public Health in India is impeccable. He flawlessly planned the state-wide and then nationwide immunization programs very successfully and hence has a fantastic grasp of the meticulous administrative outlining and planning involved in such mass immunization programs.

There is no doubt that India will defeat Coronavirus soon, but the measures by Dr. Harsh Vardhan, his ministry officers will go a long way in improving the Healthcare and Medical treatment readiness of the nation in an irreversible manner.
