Download file to see previous pages Avian Influenza or Bird Flu, as it commonly referred to, is an infection which is caused by the H5N1 virus. The natural hosts of this virus are wild birds, in particular waterfowls, who carry these viruses in their intestines while themselves remaining asymptomatic (Auewaraku 404). The transmission of this virus to domesticated birds such as ducks, chickens, and turkeys, can lead to outbreaks and epidemics of infection amongst these birds, causing a large number of them to be killed (Centers for Disease Control and Prevention). Recently, H5N1 virus is not only leading to an increasing number of epizootics but has also been implicated in several epidemics in humans. The mode of transmission of this virus has been described as being feco-oral amongst birds, whereas humans contract the disease via contact with airborne particles from infected poultry or while contact with the poultry or their fecal matter e.g. during food preparation (Fleming 1066).  The first human infection with H5N1 was witnessed in 1997 in Hong Kong, as a result of which six out of the eighteen people affected died. Ever since several similar outbreaks of human infection have been observed in various regions of the world and this has become an important public health concern (Auewaraku 404). At present, there are two different clades of the H5N1 which have been identified to be circulating amongst poultry. Amongst these, three subgroups from the clade 2 have been shown to infect humans viz. subclades 2.1, 2.2, and 2.3 Centers for Disease Control and Prevention).
Infections in humans appear on a spectrum, ranging in variety and severity from relatively milder infections such as conjunctivitis to potentially serious ones such as pneumonia and can even lead to death (Centers for Disease Control and Prevention).
The increasing outbreaks of human infection with H5N1 are of prime concern as this organism is highly pathogenic. It has a unique ability to infect humans and this poses a threat to the human race as this virus might have the potential to evolve into a form that is transmissible from person to person (Auewaraku 404). In the past, the world has witnessed several outbreaks of influenza, causing significant morbidity and mortality. If a new strain of this virulent organism emerges, it can lead to potentially catastrophic outbreaks of influenza in biologically naïve human hosts, claiming thousands of human lives. Thereby, it is important to study in detail the structure and molecular and cellular mechanisms of disease and evolution of H5N1 virus, as this would help in planning strategies aimed at keeping a check on the further spread of this organism and in the development of preventive measures such as vaccines to combat any further epidemics of this disease. ...Download file to see next pagesRead More

Ebola virus

...H5N1 Avian Virus... H5N1 Avian Virus... Virus Even though only just over a thousand people have died from Ebola since the virus was discovered, it is still considered one of the deadliest diseases in the world. This is because of the usual horrific experience someone goes through before dying of the disease. This paper will discuss about the Ebola virus and its history. Also, Ebola has five different strains that each came from separate natural reservoirs. Next, how Ebola is transmitted and what is the natural host. Other ideas that will be touched on include the signs and symptoms of the disease and how it manifests itself. Additionally, possible treatment methods and the structure of the virus will be discussed. The official name for Ebola is...

However in 1997, an influenza epidemic broke out in Asia and North East Africa (WHO, 2011). The avian subtype H5N1 had been incriminated for the several human diseases and deaths and was known to occur from infected poultry birds and farmyard animals as influenza A (CDC, 2009). The WHO had worked with the aims of identification of new cases and made attempts to reduce animal health and public health risks (WHO, 2011). The continuous effort by the World Health Organization had resulted in the WHO declaring that the world was not ready to contain an influenza epidemic in 2005. The swine flu epidemic of ...

The natural hosts of this virus are wild birds, in particular water fowls, who carry these viruses in their intestines while themselves remaining asymptomatic. Recently, H5N1 virus is not only leading to an increasing number of epizootics, but has also been implicated in several epidemics in humans. The Avian influenza virus is unique in several aspects. It has a unique structure of the HA structural protein which not only confers host specificity to the virus but is also implicated in enhancing the virulence of the organism. Moreover, this virus also has...

H5N1 Avian Virus... risks does the avian flu virus (H5N1) present to the human population Introduction: The avian influenza virus is normally an infective strain tothe birds only; however, the world now faces the threat of a human influenza pandemic arising from the recently emerged avian influenza H5N1 virus. Although of avian origin, H5N1 is of particular concern since it has recognised ability to be transmitted directly from birds to human. Historically, the emergence and spread of severe acute respiratory syndrome (SARS) in 2003 caused significant effects on the health, trade, and economies of a number of countries, particularly in Asia. This happened perhaps due to the fact that in the humans, this strain of avian virus...

Pandemic avian influenza

...H5N1 Avian Virus... H5N1 Avian Virus... global disease outbreak is known as a pandemic. A flu pandemic takes place when a new influenza virus surfaces for which there is little or no immunity for humans, and for which no vaccine is available. Influenza viruses are highly unstable, genetically adaptable, and well prepared to elude host defenses. The disease spreads easily from person-to-person, causing serious illness, and can encompass the whole country and even the world in very short time. Avian (bird) flu is caused by influenza A viruses that occur naturally among birds. There are different subtypes of these viruses because of changes in certain proteins (hemagglutinin [HA] and neuraminidase [NA]) on the surface of the influenza A virus and...

Flu Copyright Although communications is a broad science and an imperfect art, it is impossible to effectively manage a crisis without effective communications. The nature of crises differs and whereas a terrorist related blast or an industrial accident is likely to be a high speed spontaneous event, a public health crisis such as an influenza pandemic can be a relatively slow waiting game that can suddenly escalate. However, emergency or crisis management and communications plans are required to handle all types of incidents and crisis. The avian flu threat that has made itself evident recently as a result of the mutation of the influenza type A virus is a ticking time bomb that needs to be monitored...

Ebola Virus

...H5N1 Avian Virus... H5N1 Avian Virus... Ebola Virus Disease Ebola virus disease (EVD), also mentioned as the Ebola hemorrhagic fever, is an uncommon but fatal illness that is transmitted by Ebola virus carrier species. The disease predominantly affects humans and nonhumans such as primates namely, chimpanzees, gorillas, and monkeys. In reference to the World Health Organization (WHO), the Ebola fatalities average to about ninety percent of all the infected persons (Peters and LeDuc ix). Despite the high fatality rates, the illness still lacks proper mechanisms of treatment. Ebola is found to be caused by the viruses of the Filoviridae (filovirus) family. Accordingly, there exists up to five Ebola virus species. Out of the five, only four can be...
