RISK PREPAREDNESS
Wake-up call- India’s Preparedness to Disease Breakouts
The
Ebola disease outbreak draws attention to the need for preparedness and for
more government
spending
on public health infrastructure. By T.K. RAJALAKSHMI
The outbreak of the Ebola virus disease
(EVD) in some West African nations and the subsequent possibility of the virus spreading to countries in South Asia,
including India, have raised legitimate concerns not only about the state of preparedness but also about the general
state of public health infrastructure in the country. While it is true that the government took the threat of the
epidemic seriously following the global panic when an American doctor and an
aid worker got infected, the thrust of the
effort and governmental intervention seem to be symptomatic rather than
systemic.
The high mortality rate of the disease,
at 90 per cent, is attributed to the underdeveloped immune response to the
virus. And with pharmaceutical companies reluctant
to invest in producing vaccines for the disease as Ebola cases have affected
mostly the poorest countries of the world, the
need to step up public expenditure on health is of utmost importance. However,
the National Democratic Alliance (NDA)
government, despite its promises of bringing a new health policy with
stepped-up
public expenditure on health and
universal access to health services, is relying on the public-private
partnership (PPP) model to deliver services. If the
experience of the Ebola disease outbreak is anything to go by, there is a
crying need for more government spending and research on
health.
Resurgence of
communicable diseases
It is widely acknowledged that there has
been a resurgence of communicable diseases in the past decade, with their outbreak and spread confined not just to
developing countries. Following the Ebola disease outbreak, on May 2, the
National Institute of Communicable Diseases
(NICD) issued an advisory to all health-care providers, including State
surveillance officers, to keep a constant vigil and
to raise their level of awareness and knowledge of standard precautions to be
taken during the care and treatment of
suspected Ebola patients. The advisory includes instructions on sample
collection techniques and packaging conditions. It
also cautions that samples from patients are an “extreme biological risk and
that testing should be conducted under
maximum biological containment conditions”. The World Health Organisation’s
(WHO)
Twelfth General Programme of Work has
stated the reduction of “mortality, morbidity and societal disruption resulting from epidemics... through prevention, preparedness,
response and recovery activities” as one its five strategic imperatives.
In the editorial titled “Are we
prepared?” in Journal of the Association of Physicians of India (September
2014, Volume 62), its authors, Falguni Parekh and Shweta Shah,
state that India needs to walk an extra mile as far as “preparedness, response
and recovery activities” are concerned.
According to them, an estimated 47,000 Indians in Ebola-affected countries were
being
contacted by diplomatic missions and
supplied with educational material about the disease. And from August 9
onwards, passengers coming from these countries
have been asked to fill in a form detailing the places visited and symptoms, if
any, before landing. This is essentially a
screening procedure for the standard symptoms of the virus. These steps, though welcome, are not adequate, given the
potential of the virus to spread. “It is impossible to screen everyone
having some symptoms. Given the overcrowding at our airports, by the time the
affected person is identified and quarantined,
hundreds of people would have been infected,” said a health specialist with
expertise
in dealing with epidemics. The
government has restricted flights coming from Ebola-affected areas to two
international airports, Delhi and Mumbai. The
guidelines of the Ministry of Health & Family Welfare state that samples
should be collected from any person who has or has
had fever with acute clinical symptoms and signs of haemorrhage, such as bleeding of gums, nose bleeds,
conjunctival infection, and red spots on the body. But experts say the
isolation of such cases coming into the country, given the sheer
numbers, will be difficult unless those symptoms are reported by people
themselves.
High cost of PPE and
therapy
Dr K.P. Kushwaha, head of BRD Medical
College at Gorakhpur, Uttar Pradesh, has dealt with all kinds of diseases
caused by deadly viruses, including the scourge of
Japanese encephalitis that affects the district and surrounding areas each
year. He told Frontline that the Ebola
virus, which is an RNA (ribonucleic acid) virus, was a deadly one. The
guidelines issued by the Centres for Disease Control and
Prevention (CDC) were not followed by the United States government. The
personal protection equipment (PPE) comprising
gowns that covered the entire body, he said, was manufactured by private companies and was too expensive. “The
health worker who has been in contact with an infected person has to be cleaned thoroughly; even while removing the
glove, care has to be taken that it does not touch any body part. The
guidelines by the WHO and other agencies are very strict
about precautionary measures. To what extent they are followed or violated is a
big question as the risks are great,” he
explained.
There was no PPE at the airports, Dr
Kushwaha said, and expressed doubts about the manpower and resources for the isolation and screening of people, even
at the airports. The personnel deployed were only filling in forms and checking whether individuals had any fever or
cough. Quarantining was the biggest challenge, but all that had been happening
was in the nature of formalities getting
fulfilled, he said. There is no cure for Ebola, and persons
infected with the virus have to be put on oxygen and antibiotics. In the
absence of a vaccine, only an experimental medicine
or therapy such as ZMapp, which consists of monoclonal antibodies prepared from the plasma of the person infected, can
be given. “Conservative treatment and the isolation of the patient are the only possible ways out,” he said. People
returning from Liberia, Sierra Leone or Guinea had to be isolated and screened
for
symptoms, he said. “All persons
returning from the affected countries should disembark at one airport,” he
suggested. In fact, the costs itself of PPE and the
experimental therapy have come under question. Each set of PPE costs as much as
$100, and the affected countries are finding
it very difficult to pay for the PPE. Dr Kushwaha said that barring surgery
involving HIV patients, PPE was not provided anywhere in government hospitals.
The medicine, too, he said, was very
costly, at $4,000 a patient a day. The combination had to be taken until the
patient was fully cured, he said. Dr Kushwaha also
stressed the need for laboratories, biosafety laboratories in particular, in
adequate numbers. Given the nature of the virus,
special containment facilities were required, which at present were available
only at the NICD in Delhi and the National
Institute of Virology (NIV) in Pune. Experts are of the opinion that normal
pathological
laboratories are not suitable for the
testing of suspected Ebola samples.
Doctor-patient ratio
Dr Kushwaha also laments the poor
doctor-patient ratio in the country. “The number of doctors and health workers
has not kept pace with the growth in population.
The 40,000-odd doctors and 284 medical colleges are hardly enough to meet this challenge,” he said, adding that every
State should ideally have an epidemiological institution. He recommends an epidemiological control authority on the
lines of the National Disaster Management Authority to tackle an epidemic situation. The Integrated Disease
Surveillance Unit was not working well, he said, as there was no monitoring. He
recalled how at the time of the swine flu
epidemic, each hospital was sanctioned up to Rs.4 crore to establish swine flu
laboratories. None of those laboratories were
functional, he said.
The chapter on health in the 12th Plan
document notes that the total health infrastructure in the country is much
below the stated requirement. While the number of
skilled professionals has increased, they are concentrated in urban areas. In
rural areas, the numbers of accredited social
health activists (ASHAs) has gone up but only half of the additional numbers
got advanced or 5th module training. In any
case, ASHAs, who draw incentive-based emoluments, are deployed for the purpose
of reducing maternal and infant
mortality. Moreover, their regularisation and working conditions still remain
unaddressed. The chapter further notes that very few of
the facilities at the sub-centre, community health centre (CHC) and primary health centre (PHC) levels meet the
requirements laid down in the Indian Public Health Standards. The shortfall in
each category is huge: laboratory technicians
80 per cent, specialists 88 per cent, doctors 76 per cent, health workers
(male) 75 per cent, nurses 53 per cent, and
auxiliary nurses and midwives (ANMs) 52 per cent.
Over-reliance on contractual
appointments as the means of increasing service providers is another matter
mentioned in the chapter. The difference in pay and perks
for the same work between contractual and regular staff is irrational. More seriously, the health chapter in
the 12th Plan, while arguing for a comprehensive approach for health care,
observes that public expenditure on health, both
Plan and non-Plan and State and Central, was less than 1 per cent of the gross domestic product (GDP) in 2007-08. This
went up marginally to 1.05 per cent in 2010-11, which the chapter says, “needed
to increase much more”. But it does not appear that the present
government’s thinking on public expenditure is very much different from that of
the previous government. Reports of a
targeted National Health Assurance Mission with some promises of health
insurance and provision of generic variants of
essential medicines at affordable rates have appeared, but the government plans
to deliver
health care through the PPP mode as
well.
For a maximalist
approach
While the scare of Ebola should
legitimately make the authorities focus attention on India’s public health
system, some experts say there is no need to go into
panic mode as far as mortality and infectivity are concerned. Agreeing that
public health systems needed to be strengthened
immeasurably, T. Sundararaman, Visiting Professor at Jawaharlal Nehru University, New Delhi, and former
director of the National Health Systems Resource Centre, told Frontline that
while mortality and infectivity were high, it
was not impossible to control them. Liberia faced the brunt of structural adjustment
policies under the dictates of the World Bank and thereby its public health system could not withstand the onslaught
of the virus. The problem, he said, was that most public systems, facing the
kind of pressure that Liberia did, opted for a
minimalist package of health care. This was a highly selective package of
health care. “Whenever there is an emergency, there
is a maximalist response,” he said, but the approach continued to be
minimalist. He advised that at all times, there
should be a certain degree of redundant capacity. “This is to say that large
hospitals should not target 80 per cent occupancy.
We cannot expect a private hospital to keep beds vacant. There should be enough
and more number of beds to respond to
situations of emergency,” he said, emphasising that most hospitals in India
were overcrowded. “The government has
responded in terms of identifying places where the infected can be isolated and
in creating awareness, but the overall
preparedness is not there,” he said.
One of the foremost requirements,
Sundararaman said, was an efficient system of notifying diseases. The symptoms
of Ebola are similar to that of dengue
hemorrhagic fever. “One cannot prepare for an epidemic like Ebola without
having prepared for tackling epidemics on an ongoing
basis. The integration between clinical care and the city health office is an
example of such coordination and, to my knowledge,
Kolkata and Chennai are two cities that have such a system in place,” he said.
There could be a guarantee that the virus
could be restricted in the airport areas. However, most cities, he said,
including second- and third-tier ones, did not
have a robust public health system in place. “There has been much talk of a
health policy since the 12th Plan, but nothing seems
to have taken off. Public expenditure on health has remained stagnant,” he
said.
That seems to be the fundamental point.
Writing in Journal of the Association of Physicians of India, Falguni
Parekh and Shweta Shah say that the WHO has
identified some basic principles in dealing with public health emergencies of
national and international concern. Assuming that
Ebola is one such emergency, a strong and efficient response should include— after considering the socio-economic,
demographic, environmental and ecological factors that facilitate the
occurrence and
spread of the disease in
India—infrastructure for transport, triage and isolation of patients; provision
for treatment to the patients and the implementation of
infection-prevention practices, including environmental cleaning procedures
according to national and international guidelines
of the National Centre for Disease Control (NCDC), India, the WHO and the CDC;
use of unlicensed drugs and vaccines
according to the WHO recommendations; laboratory facilities for diagnosis and
sample
collection; an efficient surveillance
and reporting system; and provision of information and training to public
health officials and the community through mass
communication systems.
The Ebola disease outbreak is a wake-up
call for the government to spend more public health. According to the Jan
Swasthya Abhiyaan (people’s health movement),
even though public health care systems account for only 29 per cent of the
total health expenditure and employ less than
20 per cent of the medical workforce, they provide about 33 per cent of all outpatient care as provided by a
qualified provider and 40 to 50 per cent of all inpatient care and 100 per cent
of all preventive and promotive care. If
anything, health care requires a maximalist approach in terms of everything
beginning with public expenditure.
