Swine Flu

You remember the truly great swine flu virus epidemic of 2009, proper? Really, you don’t remember the school’s staying closed across the nation after the 1st wave of fatalities? And how people stopped eating chicken to this kind of extent that farmers simply slaughtered most of their domestic swine and then burned up the meat? You don’t understand that? Well, of course not. No-one does, since it didn’t happen. It also authentic that no person knows how come it did not happen.

The interesting question at this point, together looks to the way in which decisions were made to halt an crisis before this got started. In the aftermath in the flu season, when right now there had been zero outbreak, a large number of people belittled public health representatives for having over-reacted. Those representatives in turn asserted two points. Initial, it was far better to over-react than to under-react because the effects of the previous were much more dire than the consequences from the latter.

Furthermore, public health officials argued, there were no way to determine in the post occurences of the flu virus season as to what extent the actions that had been taken had prevented an epidemic or perhaps pandemic of flu. At times the fact there is not a catastrophe that proves that the level of response was exactly correct. This paper examines your decision process that was adopted in getting yourself ready for the 2009 flu season.

Rather than making any kind of judgement about whether the right decision was made – because it is of course difficult to determine later whether an epidemic was suppressed or just never came about – this kind of paper walks through the decision-making process according to different models of decision that focus on different root assumptions.

Bazerman and Moore’s Decision-making Model

Bazerman Moore (2008) and Bazerman (2008) have developed a six-stage decision-making model that can be applied to any kind of field. It of the newspaper uses this model to analyze the decisions produced in preparing for this year’s flu season. As will probably be discussed in greater span following the breakdown of the individual actions of this style and the ways that they could have been used in placing public health plan, while this kind of and similar models have sufficient supporters, this kind of models in many cases are criticized to be overly mechanized and reductionistic.

The first step in Bazerman Moore’s (2008) model is always to determine whether or not there is a problem. This noises so general as to not the need to be said, but it is usually remarkable when the “if it’s certainly not broke no longer fix it” axiom gets ignored. Also included in this step are the following considerations: When there is a problem, does it have to be resolved now? What happens if the decision if delayed? Who is accountable for making the decision? These steps are intuitive as well as would be the first steps for the majority of decision-making models that are being applied directly to problem solving.

The answer as to if the H1N1 flu computer virus had the potential to cause significant harm was undoubtedly yes, a thing that was well-researched in public well being research. In the matter of a potential flu pandemic, you can the possibility that there could be truly devastating consequence. Indeed, thousands and generally tens of thousands of People in america die every year from the flu virus, and at least half a million people die by flu annually, many from secondary bacterial infections (Influenza, 2003).

In fact , the worldwide loss of life rate of individuals from flu may be greater than this kind of because countries where there is likely to be a very high level of contamination are those same countries (primarily undeveloped international locations in the tropics) that are both equally burdened with highly limited public health devices and limited means (and perhaps limited incentive) to report using the rates of morbidity and mortality costs from flu. Even growing nations such as China had been slow to report the levels of illness.

The [government’s] threats [to statement the number of flu virus cases accurately] emerged after a visible Chinese doctor, Zhong Nanshan, questioned how come China’s official H1N1 death toll is still in the double digits while other countries with smaller populations content much higher quantities. He’s confident that [national] the government is definitely covering in the spread in the virus.

What a serious accusations in Cina, which endured global humiliation after looking to conceal the deadly SARS [Severe Acute Breathing Syndrome] virus in 2003. Now, China’s large size may well contribute to the problem of under-reporting. (Hatton, 2009)

The fact that initial reviews of the significance of flu virus transmission prices may be artificially (even in the event that not intentionally) low must be considered in assessing the length of time any decision on working on a flu virus epidemic may wait because initial reviews may claim that the risk is less than it truly is.

The The spanish language flu outbreak of 1918-19, which wiped out more people than got died on planet War I, swept around the world along with the soldiers going residence from the conflict. The flu virus killed actually healthy adults, who may feel “fine in the morning” and yet be dead by the time that the sunshine had dropped (Pandemic flu virus history, 2011).

Some of the stats that help to make the level of the Spanish flu outbreak are the pursuing: 1) Roughly 20% to 40% in the worldwide inhabitants became ill; 2) Around 50 , 000, 000 people perished 3) Practically 675, 1000 people died in the United States (Pandemic flu record, 2011). One of the reasons that this flu virus pandemic proved to be so lethal was that the virus responsible for it was new and so persons did not come with an immunity to it.

Influenza viruses, similar to most viruses, can adjust quickly. It really is for this reason that having the flu one year will not protect an individual the next year. Although the computer virus that arrives each year is similar enough towards the previous type to be regarded as a form of the same disease, it is usually significantly diverse. H1N1 was obviously a virus that was drastically different from previous flu viruses, and so it had a greater potential than most versions from the flu to cause a excessive rate of infection and a high level of fatality.

“It’s a fresh virus in whose biological houses we’re still not sure of, ” explained Andrew Pekosz. “And with influenza, it’s been documented that different pressures have a differential ability to cause disease in animals and in humans. And at the moment, we’re receiving mixed alerts about this virus’ ability to trigger disease. inch (Researchers competition to develop swine flu shot, 2009)

The 1918 flu virus pandemic likewise spread therefore quickly since it was carried home across the globe by troops returning residence from battle. H1N1 will not be sent in this way, good results . international travelling of thousands and thousands of people throughout a single flu virus season, the spread in the disease could possibly be incredibly fast.

There had not been a flu virus pandemic because severe since that time, but the damaging consequences of the flu virus to which a persons population has not been exposed, which will had been demonstrated by the 1918-19 pandemic, which the emergence of your new tension of influenza was enough to set off alarm alarms throughout the public well-being community. As a result, step one of Baverman Moore’s model have been satisfied: There was a probably serious problem, and it was the one which had to be served on with alacrity.

Among the key axioms of public well-being is that a vaccination system to be effective it ought to be started in the beginning. Once a number of the human population becomes infected (what the percentage is depends on a number of elements, including the kind of pathogen) a vaccination system will have little or no effect. This precept is called “herd immunity” or “community immunity” and is also a well-researched medical fact:

When a important portion of a community is immunized against a contagious disease, most people of the community are safeguarded against that disease since there is little chance for an outbreak. Even individuals who are not qualified to receive certain vaccines – including infants, women that are pregnant, or immunocompromised individuals – get some protection because the distributed of infectious disease can be contained. This is known as “community immunity. inch (Community defenses, 2010)

Idea of “herd immunity” answers the question of why it might have been very problematic to hold back any significant length of time before making a decision to behave.

Among the additional key questions posed in step one of it is, after determining there is a problem is always to determine who will be responsible for supplying a solution to the problem. The answer to this part of the model is usually that the most important stars in the option are public welfare officials working on national and international amounts. Viruses can fly around an international line instantaneously so any intervention that has a potential for being successful must have intercontinental cooperation.

Although other celebrities are also responsible as a required part of virtually any intervention: Primary care physicians for diagnosing flu patients, individuals to be vaccinated as well as for
