[The testing rate in India is scandalously low.
Among the lowest in the world.
Without testing, no one'd be reported "infected", nor any death would be
counted as corona related death.

While in India, the ferocity of the spread may indeed be lower, the figures
are just not comparable with those pertaining to other countries.

For lower level of threat - if so assumed, as yet, five possible factors
have been put forward.
I. Indians have higher disease immunity being constantly exposed to various
diseases and/or, also, genetically different.
II. India is younger - favourable age profile of the population.
III. India being a malaria affected zone, a lot of hydroxychloroquine is
being consumed.
IV. BCG vaccination, at birth, is mandatory, since 1948.
V. Hot summer.

On the flip side:
I. Poverty - even despondency, and malnourishment is widespread.
II. Suffering from diseases has further lowered immunity.
III. Too densely populated - especially, in specific clusters.
IV. Miserable state of health infrastructure.

A clearer picture is bound to emerge - regardless of lowered figures on
account of low testing rate, in course of the coming four weeks.

However, it'd, in any case, remain a question mark what happens when the
summer is over - say, in September.

The latest available cumulative figures for India: 4822 confirmed infected
and 133 reported dead (ref.: <https://www.covid19india.org/>).
Globally: 1,347,587 / 74,782 (ref.: <

Dr N Devadasan is a public health professional with more than 30 years of
experience both at the grassroots level as well as in research and
teaching. He has worked with the World Health Organisation as its national
programme officer for communicable diseases in India. He has contributed
significantly to the design of the health ministry’s Integrated Disease
Surveillance Programme. He has also investigated various outbreaks,
including three Nipah outbreaks in Bangladesh and India. He is currently
the technical advisor to Health Systems Transformation Platform, a
non-profit organisation.

In this piece, Devadasan examines the available data for India’s
coronavirus outbreak and argues that the country may have overreacted. He
addresses four common questions in light of the available evidence.

1. Will the coronavirus infect millions in India?
In Wuhan in China and Italy, tens of thousands are affected and thousands
have died. While the disease spread at both these centres at alarming
rates, other countries and especially India are currently not showing a
similar trend.

Until March 3, India had only three confirmed Covid-19 cases – students who
had returned to Kerala from Wuhan. In the month since then, Covid-19 cases
have cropped up across the country, but the number remains 1,251 as of 4
pm, March 31.

Compare this with other European countries or China, where the number of
cases has rapidly crossed the 10,000 mark, as the chart below shows.


Among the 195 countries that have patients with Covid-19, India ranks 41st
in terms of the number of confirmed cases. Considering that India is the
second-most populous nation in the world and usually during epidemics,
larger countries tend to have a higher number of cases, what explains the
fact that there are fewer cases in the country?

Standardising the cases by population, the number of cases in India is 500
to 2,000 times lower than other countries, especially the European
countries.


2. Are the numbers in India low because of inadequate testing and
underreporting?
Many experts have complained that the government has not been testing
enough people for Covid-19. However, most textbooks of applied epidemiology
will tell you that once the agent of an outbreak or epidemic is
established, there is no need to test new symptomatic patients. It is a
waste of resources since there is no difference in the treatment provided
to a “probable” Covid-19 case and a “confirmed” Covid-19 case.

At this point, we should consider anybody with a fever and cough as a
probable Covid-19 patient and ask them to be self quarantined. The patient
and their contacts should be monitored closely for any deterioration in
clinical conditions (temperature, respiratory rate, fatigue) and if there
is a deterioration, then and only then should they be shifted to a hospital
where they may be tested for Covid-19 to confirm the diagnosis. This
strategy will save beds, health staff time and will also keep 80% of
patients out of hospitals.

Therefore, the government is right in limiting the testing to those who may
be at risk. The effort should not be to diagnose more cases but to ensure
that those who are sick are treated promptly.

A related question arises: if India is indeed underreporting the numbers
for Covid-19 and there are thousands of untested patients out there, then
why have they not shown up in hospitals already? It is nearly a month since
the first case of local transmission was reported. Given the panic, it is
unlikely that patients are sitting at home. For more than a week now,
because of the lockdown, clinics and health centres have been closed, which
makes it more likely that the patients will end up in the hospitals, which
are few and easily monitored.

While it is true that most diseases are underreported in India, some states
do better at disease surveillance: Maharashtra and Kerala, which are
reporting high number of Covid-19 cases, are both relatively
well-performing states. It is unlikely that the new cases and deaths will
be missed in these two states. If there is a surge in patients with
respiratory symptoms in hospitals, it is unlikely to miss the attention of
the media. Such information is hard to suppress in a country like India. So
where are these untested patients? Maybe they do not exist.

3. Will the epidemic explode uncontrollably in India?
The fear is part of the “spread to millions” discourse. However, comparing
countries that confirmed their first Covid-19 cases around March 3, we see
two different groups of countries, as visible in the chart below.


European countries (red lines) have an exponential trajectory. In contrast,
countries located in North Africa and the Middle East (blue lines), as well
as India (the thick green line) have a linear trajectory. This is further
highlighted when we compare the most affected countries with India.


The X-axis is the number of days since the onset of the outbreak, and we
see once again that India is performing very differently from other
countries. The number of Covid-19 cases in India is rising by a factor of
1.45, compared to a factor of 198 in Italy.

We are currently not following an exponential trajectory compared to other
countries. This begets the question: will the epidemic play out differently
in India compared to European countries?

4. Will the coronavirus kill lakhs in India?
Many have been rattled by the mortality rate often cited in the media:
3%-5%. However, one needs to look closely at this figure. As of March 27,
the average case fatality rate in India was 4.5 deaths among 100 patients.

However, the average is not the right measure to use in such a situation
since it is affected by extreme values. For example, in Tanzania, out of
three Covid-19 patients, one died, so the case fatality rate is 33%. You
will see this similar pattern in countries with low incidence of the
Covid-19. Their case fatality rate is high and this contributes to the
higher average.

On the other hand, the median is not affected by extreme values and gives
you the 50th percentile of the case fatality rate. Using the median, the
case fatality rate for India drops to 0.4 deaths per 100 patients, nearly
ten times. Data from 195 countries shows 95% of the countries will suffer a
case fatality rate between 0 and 0.8 deaths per 100 patients.

This case fatality rate further falls if we include the untested
asymptomatic patients into the calculation. As I do not have those figures,
I hesitate to arrive at any conclusion.

However, it is worth looking at population-based death rates to get some
perspective. Hubei province where Wuhan is situated has a population of
5.85 crores, comparable to any of our medium-sized states. This province
saw a total number of 3,295 Covid-19 deaths, that is, a death rate of five
persons per one lakh population. Without the Covid-19 outbreak, an Indian
state with a population of six crore would have seen about 420,000 deaths
every year, that is, 1,150 deaths every day because of heart attacks,
strokes, road traffic accidents, diarrhoea, pneumonia and cancers. At the
current rate of cases in India, Covid-19 related deaths are likely to be
less than 1% of this usual number of deaths.

In Italy, the estimated deaths for a similar population size would be
27,000 – nine times more than Wuhan. The point to note is that most of the
deaths happened among adults more than 70 years of age. Given that 23% of
the Italian population is elderly, it is not surprising that the death rate
in Italy is high. On the other hand, India, with only 6.3% of its
population above 65 years of age, is unlikely to see this level of
mortality.

More questions
Indians have been driven into a panic mode because of the deaths reported
in Italy and Wuhan. But India is not Italy, it is not China: our genetics,
environment and people are very different.

So far, we have not seen an exponential growth in Covid-19 cases as
predicted by various experts and simulations, despite our large population,
overcrowding, low level of hygiene and the laissez-faire attitude of the
public. We can only speculate about the possible reasons:

Contact tracing and quarantining ensured that the outbreak was largely
limited to family contacts and did not spill over to the community.
The weather in India is not conducive for the virus to spread as rapidly as
it did in Wuhan and Europe. Indians have an innate immunity to the virus,
thanks to unhygienic conditions.
This hypothesis can be quickly confirmed by doing serological surveillance
among the non-contact populations to see whether they have an antibody to
the Sars-CoV2. The Indian Council for Medical Research has already
announced plans for such surveillance.
The bottom line is that the data available so far suggests that the novel
coronavirus may not infect millions of people in India as predicted by some
mathematical simulations. Most patients would possibly only suffer from a
cough and fever and recover without any residue. Some will succumb to this
virus, but the numbers will most likely not be as high as predicted.

While simulations predict dire situations, we need to keep in mind that
simulations are based on assumptions. In contrast, I have drawn conclusions
based on the current path of the virus in India based on available data.
Let us hope that I am right.
