Abstract

Management of flu pandemic is a perpetual challenge for the medical fraternity since time immemorial. Animal to human transmission has been observed thrice in the last century within an average range of 11-39 years of antigenic recycling. The recent outbreak of influenza A (H1N1, also termed as swine flu), first reported in Mexico on April 26, 2009, occurred in the forty first year since last reported flu pandemic (July 1968). Within less than 50 days, it has assumed pandemic proportions (phase VI) affecting over 76 countries with 163 deaths/35,928 cases (as on 15th June 2009). It indicated the re-emergence of genetically reassorted virus having strains endemic to humans, swine and avian (H5N1). The World Health Organisation (WHO) member states have already pulled up their socks and geared up to combat such criticalities. Earlier outbreaks of avian flu (H5N1) in different countries led WHO to develop pandemic preparedness strategies with national/regional plans on pandemic preparedness. Numerous factors related to climatic conditions, socio-economic strata, governance and sharing of information/logistics at all levels have been considered critical indicators in monitoring the dynamics of escalation towards a pandemic situation.

The National Disaster Management Authority (NDMA), Government of India, with the active cooperation of UN agencies and other stakeholders/experts has formulated a concept paper on role of nonhealth service providers during pandemics in April 2008 and released national guidelines - management of biological disasters in July 2008. These guidelines enumerate that the success of medical management endeavors like pharmaceutical (anti-viral Oseltamivir and Zanamivir therapies), nonpharmaceutical interventions and vaccination development etc., largely depends on level of resistance offered by mutagenic viral strain and rationale use of pharmaco therapeutic interventions. This article describes the mitigation approach to combat flu pandemic with its effective implementation at national, state and local levels.

<abstract>
<p>Management of flu pandemic is a perpetual challenge for the medical fraternity since time immemorial. Animal to human transmission has been observed thrice in the last century within an average range of 11-39 years of antigenic recycling. The recent outbreak of influenza A (H1N1, also termed as swine flu), first reported in Mexico on April 26, 2009, occurred in the forty first year since last reported flu pandemic (July 1968). Within less than 50 days, it has assumed pandemic proportions (phase VI) affecting over 76 countries with 163 deaths/35,928 cases (as on 15
<sup>th</sup>
June 2009). It indicated the re-emergence of genetically reassorted virus having strains endemic to humans, swine and avian (H5N1). The World Health Organisation (WHO) member states have already pulled up their socks and geared up to combat such criticalities. Earlier outbreaks of avian flu (H5N1) in different countries led WHO to develop pandemic preparedness strategies with national/regional plans on pandemic preparedness. Numerous factors related to climatic conditions, socio-economic strata, governance and sharing of information/logistics at all levels have been considered critical indicators in monitoring the dynamics of escalation towards a pandemic situation.</p>
<p>The National Disaster Management Authority (NDMA), Government of India, with the active cooperation of UN agencies and other stakeholders/experts has formulated a concept paper on role of nonhealth service providers during pandemics in April 2008 and released national guidelines - management of biological disasters in July 2008. These guidelines enumerate that the success of medical management endeavors like pharmaceutical (anti-viral Oseltamivir and Zanamivir therapies), nonpharmaceutical interventions and vaccination development etc., largely depends on level of resistance offered by mutagenic viral strain and rationale use of pharmaco therapeutic interventions. This article describes the mitigation approach to combat flu pandemic with its effective implementation at national, state and local levels.</p>

<title>INTRODUCTION</title>
<p>Human civilization is exposed to a number of natural pathogens which are continually re-emerging from time-to-time by shifting from other host species where they have already established a complete reservoir of different variants. Such a switch over has often led to some of the most devastating epidemics recorded, including Human Immunodeficieny Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) in human communities.[
<xref ref-type="bibr" rid="CIT1">1</xref>
] This has even been argued that many microbial diseases affecting mankind (.like measles, tuberculosis, influenza and smallpox) emerged through pathogens jumping from domestic animals to humans on an evolutionary scale. A similar phenomenon also led to some of the devastating epidemics of plant pathogens in crop species like potato late blight in the cultivated potato and near extinction of American chestnut trees by chestnut blight.[
<xref ref-type="bibr" rid="CIT2">2</xref>
]</p>
<p>The etymology of the word pandemic can be traced to a Greek word
<italic>pandemos ‘pertaining to all people’ from pan -</italic>
‘all’ plus
<italic>demos</italic>
meaning ‘people’. It could also be referred to as a widespread epidemic of contagious disease affecting whole of a country or one or more continents at the same time.[
<xref ref-type="bibr" rid="CIT3">3</xref>
] Human pandemics is a situation in which a local pathogen with epidemic potential gains and mutagenic ability affects humans on a national, regional or global scale. Its management requires active participation of various emergency functionaries with harmonization of their actions to avoid associated panic.[
<xref ref-type="bibr" rid="CIT4">4</xref>
] China and India, being thickly populated zones of South East Asian regions, are maximally vulnerable to such situations. India has already faced avian flu epidemics in the states of Maharashtra, West Bengal, Tripura. The continued presence of the pathogen enhanced the possibility of reoccurrence of incidence in future.</p>
<sec id="sec2-1">
<title>Influenza outbreaks- transformation towards human pandemic</title>
<p>The actual account of influenza in humans probably dates back to the 12
<sup>th</sup>
century, however, possible pandemics are documented as far back as 1510, but the first one to be clearly recognized occurred in 1580.[
<xref ref-type="bibr" rid="CIT5">5</xref>
] Retrospective analysis of sera collected from individuals born as early as 1857 revealed that the virus emerged in different strains leading to various pandemics. The reliable epidemiological data is, however, available from 1889-1892 pandemic onwards. Though influenza virus was first isolated in 1933, majority of the present day lessons learnt are based on epidemiological findings from 1918-1919, 1957-1958 and 1968-1969 pandemics[
<xref ref-type="bibr" rid="CIT5">5</xref>
]. At least two of these pandemics of the 20th century were associated with the re-emergence of such viruses similar to those which were circulated in previous eras, a process referred to as antigenic recycling[

<p>There have been regular outbreaks of influenza since 1996 to 2006 attributing towards genetics of the virus. It is pertinent to share knowledge regarding the virus and its virulence.[
<xref ref-type="bibr" rid="CIT7">7</xref>
] Recent episodes of influenza virus (H5N1) in South East Asian countries and other parts of world led global attention towards the impending pandemics. It is important to understand that evolution of Avian Flu pathogen capable of affecting humans will be inherently unpredictable, even though emerging pathogens tend to share some common traits. In case of direct transmission through RNA viruses, it was anticipated that they were most likely to jump between host species.[
<xref ref-type="bibr" rid="CIT8">8</xref>
] However, the spread of H5N1 virus from human to human transmission has not been observed in India.[

<title>PANDEMIC PREPAREDNESS STRATEGY</title>
<p>In view of the urgency of issue, WHO has now invoked the pre-established global pandemic preparedness plans and strategies for effective management..[
<xref ref-type="bibr" rid="CIT11">11</xref>
–
<xref ref-type="bibr" rid="CIT12">12</xref>
] The strategy encompasses following key performance areas: (1) capabilities-based planning based on cooperative governance, (2) equipping to manage various types of risks, (3) training and education towards development oriented approach, (4) exercising and evaluation to enhance reflexes and; (5) identification and incorporation of lessons learned.[
<xref ref-type="bibr" rid="CIT13">13</xref>
] In the aftermath of 9/11 incidence and anthrax attacks, there is an increased possibility of bioterrorism incidences leading to pandemics. It calls for preparedness that will transcend across the boundaries to manage any myriad mass casualty incidences. The looming potential for an avian (bird) influenza pandemic or an intentional usage of virulent microorganisms against civilian population is, therefore, a very distinct possibility.[
<xref ref-type="bibr" rid="CIT14">14</xref>
]</p>
<p>Impact will range from severe human sufferings to disruption of complete social system. It will eventually leads to a situation of helplessness and hopelessness. Inadequate preparedness will seriously delay overall detection and treatment efforts. An effective cooperation with authorities involved in surveillance, contact tracing and isolation measures; optimal distribution of resources for the prophylactic and therapeutic measures are important mitigation strategies requiring strict enforcement.[
<xref ref-type="bibr" rid="CIT15">15</xref>
<xref ref-type="bibr" rid="CIT16">16</xref>
] These mitigation strategies need to be complemented by local level/house hold based interventions which are effective tools to control spread of lower transmissibility strains during initial phase of spread of flu. Though community awareness and its active participation might reduce the number of incidences towards development of severity a combination of household-based quarantine, isolation of cases outside the households and targeted use of vaccines and specific anti-viral therapies appear to be highly effective and feasible.[

<p>The present review outlines the inherent potential of switch over of avian influenza epidemic into a human pandemic, H1N1 pandemic 2009; major attributes towards emergency pandemic preparedness, health care preparedness, role of non-health care stakeholders and simulation exercises as learning tools for effective management of pandemics.</p>

<title>EMERGENCE OF FLU OUTBREAKS AS FUTURE PANDEMICS</title>
<p>Influenza is a highly contagious, acute respiratory disease that spreads rapidly and pervasively through a population with diverse susceptible reservoirs of influenza virus. A mutated virus strain to which people have no immunity can cause influenza pandemic once the virus gains efficient and sustained human-to-human transmission capability. Extremely high case-fatality ratio among confirmed cases with genetic sequencing of influenza A (H5N1) virus from human cases in Thailand and Vietnam has been reported from 2004 to 2006.[

<title>Avian influenza virus - low and highly pathogenic forms</title>
<p>Avian influenza virus uses protein marker hemagglutinin (H) to adhere and inject within a host and protein marker neuraminidase (N) is responsible for the virus' capacity to reproduce its progeny once it has infiltrated its host cell's DNA. These H and N proteins are used to classify different types of avian influenza viruses, and scientists have found that the H5 and H7 subtypes are the most likely to mutate and have potential to become deadly human pandemics.</p>
<p>Amongst them, H5N1 was found to have significantly high potential mutability.[

] Avian influenza exists in both low-pathogenic and high-pathogenic forms differing in its inherent ability to harm its host, and its capacity to spread between and among various host species. Low pathogenic avian influenza (LPAI) does not cause any illness in domestic poultry while an H5 or H7 LPAI strain posses significant potential to evolve into a highly pathogenic avian influenza (HPAI) strain.[
<xref ref-type="bibr" rid="CIT19">19</xref>
] HPAI is frequently fatal to domestic poultry and wild birds as it is easily transmissible between the susceptible species. The migration potential among different species across geographical boundaries led to the possibility of emergence of avian influenza virus as human influenza virus with a significant pandemic potential. Such jumps have already threatened species including lesser white-fronted goose, red-breasted goose, swan goose, oriental stork, Siberian crane and bar-headed goose. Recent reports from swine to human transmission have opened the pandemic potential of the virus.[

Among these reassortants, H5N1-PR2 (responsible for Hong Kong outbreak) and H5N1-PR7 were found to be associated with confirmed human cases.

<title>Effect of climatic and socio-economic factors</title>
<p>During inter-pandemic periods, in northern and southern temperate regions, the epidemiology of influenza is characterized by extremely low level transmission of influenza virus in summer months. It is generally followed by an annual upsurge in winter seasonal activity with clinically recognizable disease in the population for 8-12 weeks. On occasions, epidemics lasting four to six weeks, with an impact on both primary and secondary care were observed. In tropical and sub-tropical regions, although seasonal peaks of increased activity may be observed, the disease usually occurs year-round.[

<p>In India, fresh outbreak of highly pathogenic avian influenza (HPAI) has been reported in North Dinajpur of West Bengal. It started on March 17, 2009 and affected 363 rural backyard poultry. Epidemiological investigation, culling within an area of three-km-radius and continued surveillance will be carried out in an area of 10-km-radius. There were reports of HPAI outbreaks in poultry in Darjeeling and Dakshin Dinajpur, Coochbehar districts of West Bengal and Ravongla district of Sikkim of India in January-February 2009. So far, no cases of human avian influenza have been reported from India. Last two years have seen a series of incidences in Maharashtra, West Bengal, Tripura and other parts of North-East. Due to the nonavailability of track and trace mechanisms, mass culling or killing happens when detected. In 2006 itself, Rs. 2200 crore have been lost. The porous borders, supply chain inefficiencies and inadequate infrastructure make it a regional level issue. The integrity of supply chain with adequate awareness strategy is an important mitigation strategy.[

<p>On the other hand, sporadic occurrence of avian influenza outbreak is linked with annual wild bird migration and their interaction with local species, illegal poultry trade across the boundaries, local backyard poultry which comes frequently in contact with ducks and other species as well as porous international borders of developing countries.

<title>Analysis of spread of H1N1 pandemic during first 50 days</title>
<p>During the period of only 50 days (26 April 2009 to 15 June 2009), 76 countries officially reported 35928 cases of influenza A (H1N1) infection, including 163 deaths.

<p>The analysis of spread of H1N1 infection at an interval of 10 days from April 26 to June 15, 2009, revealed some important findings. The global increase in spread over this time period exhibited wave- like nature with lowering of spread half way (25-30 days i.e. May 26, 2009) and then peaking up. A similar pattern is observed in rate of increase of number of deaths with respect to increase in number of countries being affected [

<p>The ILI can cause a lowering of the immune system capability and a susceptibility to pneumonia.

Since human cases have been reported with geographical spread of multiple community outbreaks and the unusual age groups affected (young adults); these events are of high concern. It is containable as it is susceptible to oseltamivir and zanamivir that can help to control the infection and help to prevent spread.</p>

Flu infection occurs even if one has been successfully vaccinated against that strain of flu. The patients may have some mild common cold symptoms or may not have any symptoms at all.[
<xref ref-type="bibr" rid="CIT51">51</xref>
] However, if the mutation is highly lethal and existing vaccines like sanofi pasture H5N1 avian flu vaccine and others do not work against the offspring virus, such pandemic will certainly lead to mass casualty events across the globe.</p>
<p>Developed countries have already developed effective vaccines for their entire population but it may constitute only five per cent of the total global population.[
<xref ref-type="bibr" rid="CIT52">52</xref>
] Recent studies showed that young healthy adults become immune with a reduced (half) dose of killed flu protein if it is given combined with an adjuvant. Such technology will eventually be an effective tool as H5N1 candidate adjuvant vaccine for cross-protection against lethal H5N1 challenge in ferrets.[
<xref ref-type="bibr" rid="CIT53">53</xref>
] As observed in previous pandemic waves [
<xref ref-type="fig" rid="F0001">Figure 1</xref>
], the first wave might affect millions in one go followed by a latency period which should be utilized effectively to produce a viable vaccine against newly evolved virus.

<p>Predictions revealed that 25-50% of the population will become sick during first wave itself. The number of patients during the first wave of pandemic depends upon the clinical response to anti-viral or anti-flu antibiotics.</p>

<sec id="sec2-14">
<title>Oseltamivir therapy</title>
<p>Oseltamivir is an orally active antiviral drug that is used in the treatment and prophylaxis of both influenza A and B. It is currently marketed under the trade name tamiflu. It is a neuraminidase inhibitor and prevents new viral particle from being released by infected cells. If treated successfully, it needs no further vaccination. The WHO has recommended that every country establish a stockpile of enough drugs to treat 20% of its citizens to manage any possible avian influenza pandemic. It works effectively if it is given early within the first 48 hours of the illness with a dosage of one tablet for five days. However, it has some common adverse drug reactions (ADRs) of such therapy like nausea, vomiting, diarrhoea, abdominal pain and headache. In 2007, Japanese investigators detected neuraminidase-resistant Influenza B virus strains in individuals who had not been treated with these drugs. The prevalence was 1.7%. It indicates that it might not work if the mutation favours such resistance.[
<xref ref-type="bibr" rid="CIT59">59</xref>
] The indiscriminate use of antiviral drugs may lead to drug resistance. One of the strategies to prevent drug resistance may be usage of both therapies i.e. zanamivir and oseltamivir.[

or zanamivir, though has not been completely established yet. Zanamivir is a transition state analogue inhibitor delivered through an inhaler used in the treatment and prophylaxis of both influenza A and B. If given within six to 12 hours, it is ideal for treatment. It may cause bronchospasm so it should be administered with apparent safety in patients with asthma or chronic obstructive pulmonary diseases. It is specific and has not been known to cause toxic effects as it does not spread around through the body's systemic circulation. It also shows no signs of viral resistance yet.</p>

<title>Limitation of health care interventions</title>
<p>Avian flu has been found to be resistant to the other older anti-influenza drugs like amantadine. It is important to understand that medical preparedness has the limitation of failure of prediction of understanding virus. The important factor to be considered is that even during first wave, the hospital health care facilities will be exhausted, lot of health care workers may themselves get affected or died, hospital will quickly run off supplies and medical logistics due to shortage of other laboratories and absenteeism in pharmaceutical industries and other industries.[
<xref ref-type="bibr" rid="CIT61">61</xref>
] It is important to develop flu survival kit including various household items like ibuprofen, acetaminophen, table sugar, and table salt, thermometer, an automatic blood pressure and pulse monitor required to manage it effectively during primary attack. The national stockpile program is required to be in place for development of stockpiles at strategic location across the country. However, any such program will remain ineffective unless and until essential services other than health sector are not in place and secured.</p>

<title>CONCLUSIONS</title>
<p>Influenza A pandemic is no longer hype or horror but a reality spreading at a very dangerous speed. It is the responsibility of every stakeholder/essential service provider, policymaker, decision maker to act proactively to prevent/prepare for any such emergency situation. India has proactively launched Integrated Disease Surveillance Programme (IDSP) as part of national health programs. NDMA issued national guidelines for management of biological disasters in July, 2008 as mandated by DM Act, 2005. Guidelines for preparedness/mitigation of pandemics especially by all non-health care providers which need to be integrated with pandemic preparedness health plan were developed by Department of Health and Family Welfare as per WHO guidelines. They include public private partnership models to maintain business continuity of essential sectors and special provisions for different vulnerable groups to be included as a part of overall plan.</p>
<p>Media management is an effective tool to alleviate stress or panic among the civilian population and utilization of this sector in a disciplined and effective manner is a complex task required to be proactively amalgamated in the overall preparedness efforts. Besides protecting their own citizens, various countries should work in unison towards global mitigation strategy.[
<xref ref-type="bibr" rid="CIT66">66</xref>
] Adequate preparedness of every essential service provider to sustain their services during pandemics is important. Practising the pandemic medical management plans through simulation-based exercises enhance the level of reflexes and augment the operational readiness. In addition to health sector plans, the execution of business continuity and contingency plan with optimal use of man and material resources is critical to develop disaster resilience. Contingency planning also needs to be in place;[
<xref ref-type="bibr" rid="CIT67">67</xref>
] if H1N1 again reassorts (by reentering into pigs population) either with seasonal virus or H3N2 virus in pigs, it could lead to changes in its replication and virulence as well as probability of anti viral drug resistance.[
<xref ref-type="bibr" rid="CIT57">57</xref>
]</p>
<p>In all such cases, the present mitigation strategy might not be effective. It is apparent to promote a global collaborative approach from health care experts, government and media, to control and curb the spread of infection worldwide.[
<xref ref-type="bibr" rid="CIT68">68</xref>
] In conclusion, it is the right time to execute the plans and ensure optimal utilization of all resources to respond effectively to impending waves of present day emergency of H1N1 pandemic.</p>
