Bird Flu: The World Beware

Avian influenza virus or which is more commonly known as bird flu is a virus that stems from an infection from wild birds. These particular birds generally carry the virus but are somehow immune to the effects of it. Domesticated birds like ducks, chickens and turkeys however are not and herein lies the problem for humans.

The bird flu virus is passed on from chicken to chicken through their saliva and feces. This can happen when flocks of chicken or other domestic birds interact with the local native birds like wild ducks, turkeys etc. This can have a catastrophic effect on a flock of poultry and many farmers have had to terminate whole flocks resulting in huge losses for them overall.

So how does the bird flu virus get passed onto humans? Well usually the avian influenza virus is found chiefly in birds, however infections can also be found in humans. The risk however is very low for most people because the virus does not generally effect humans. However many cases have surfaced around the globe of people becoming infected by poultry such as in recent times.

Another concern is that the human strain of influenza originated from bird flu, therefore some scientists believe that there is a chance that one day the bird flu virus could transform into a strand that may be deadly to us humans. This could then cause a major outbreak around the world. After a recent breakout in Asia, people are becoming more and more wary about the fact that there is a possibility of a breakout occurring in their local area. This is unlikely to occur but it is important to remember that such events do happen and one of the best things to do now is to learn everything there is to know about bird flu and other strain of influenza

Many people believe this may happen sooner rather than later and are now getting ready for this to occur. There are many products being sold today to help protect people from becoming infected if an outbreak occurs. One way to reduce the likelihood of picking up a strain of influenza like bird flu would be to increase your body's immune system so that it becomes stronger and is able to fight off infection easier. This is a surefire way to keep you and your family safe from not only bird flu, but many other unwanted viruses.

Worried About Bird Flu? Pest Birds Cause More Problems Than You May Know

Birds are beautiful, wild creatures of nature and most reside in rural environments that provide natural shelters for them. However, some bird species have successfully adapted to our urban environment. The pigeon, starling and house sparrow -- among others -- thrive in our buildings and on our food. Their adaptation to our communities has brought them into close proximity to humans, often conflicting with us in our cities and suburbs. Although there are many different problems associated with pest birds, they can generally be grouped into two main categories: damage and disease.

How Pest Birds Harbor and Spread Disease

Headlines scream of late about the spread of bird flu, encephalitis, salmonella and among other diseases, raising the public's awareness about the role pest birds play in the spread of disease. Yet, there are still many who underestimate the health risks associated with birds.

Birds are a perfect mechanism for spreading disease as they travel great distances, harbor a variety of parasites and can host internally a plethora of infectious diseases. While in general human interaction with most bird species is minimal, as more birds like pigeons, sparrows, starlings and gulls, become urbanized and we develop further into the suburbs (their natural habitat), they come into contact with humans more frequently, thus increasing the potential for the spread of diseases.

Diseases are carried by birds in several ways: 1) they are contained inside the bird and passed on through defecation, 2) they are present in the bird's nesting materials or droppings, and spread wherever these materials are left, and 3) the disease is inside a parasite the bird hosts.

The most common way a disease is transferred from bird to human is when a diseased bird directly defecates into a human food or water source. In the summer of 93, New York faced a health crisis when several hundred people came down with a mysterious ailment. The illness was traced to seagull droppings in an old city reservoir. Even if the feces are not dropped directly onto exposed food or water, airborne spores from drying feces in air ducts and vents or anywhere nearby can settle on exposed food and transfer disease. Several thousand cases of food poisoning (salmonella) every year can be attributed to this disease transmission route.

As bird droppings and/or the contaminated soil it rests on dries or is disturbed, microscopic pieces break off and become airborne. The airborne particles can contain dormant fungi and/or bacteria. When breathed into the lungs, the warm, moist lung lining provides a breeding ground for the infectious agents. Generally this infection lasts a few days, is flu-like in nature and the body's defenses contain the invaders before minor symptoms appear. However, in some cases, major infections cause long term disability and, in the extreme cases, death. An example of this occurred after the Northridge earthquake, when several thousand people came down with flu-like respiratory symptoms called Valley Fever, caused by breathing in dust and airborne debris filled with histoplasmosis spores and related fungal agents stirred up by the earthquake. It is important to note there is no known medical cure for internal fungal infections.

Direct contact with feces can also cause infections, such as when fecal dust or droppings get inside a wound or cut. The wound site becomes red, puffy and pus-filled. Antibiotics are often needed to cure the infection. In some rare cases, infection of the blood (septis) or internal infection can also occur, causing serious illness or death. Proper attire must always be worn around bird droppings, and special care used when cleaning a bird site or installing bird control products. If a cut or injury occurs, thoroughly wash and disinfect the wound and cover with a sterile bandage to minimize risk of infection.

Parasites harbored by pest birds like ticks, fleas, mites and mosquitoes, etc., are a key component in the spread of infectious diseases. Parasites transfer diseases by biting an infected animal and sucking in blood containing the germ, then passes the germ along when it bites its next victim. Over forty types of parasites often live either on birds, in their nests or in places they roost. They are responsible for the transmission of several hundred viral and bacterial agents including: plague, encephalitis, pox and meningitis. Paradoxically, this threat can be aggravated when bird control products are installed if the installer does not thoroughly clean and disinfect the site with a hospital-grade disinfectant to eradicate the parasites. If they do not clean the site when the birds are excluded, mites, fleas, ticks, etc., will seek a new host, often the human inhabitants in the area. Therefore, a proper bird control project will always include parasite extermination and thorough cleaning of the entire site.

Damage Caused by Pest Birds

Pest birds are responsible for tens of millions of dollars of damage every year to buildings, machinery, automobiles, roofs, ventilation systems and much more. Accumulated bird droppings and nesting materials cause a host of physical problems, sometimes very serious in nature, if not corrected immediately. Besides the liability concern of people slipping and falling on droppings that gather on walkways, bird droppings and nesting materials are responsible for a host of other types of property and structural damage as well.
Bird droppings are very acidic in composition and "eat" away at many substrates, especially tar-based roofing materials. Piled bird droppings on roofs can wear through many types of material, eventually causing leaks. The life expectancy of a composite roof can be cut in half by just a light, but continuous, application of bird droppings. Pigeon, starling and sparrow nests are often built in rain gutters, drains and the corners of roofs where drains are located. Each year buildings of all types experience damage and occasionally, in extreme cases, roof collapses, when drainage systems are blocked with bird nests and droppings and standing water rises to a level the roof cannot support.

Bird droppings and nesting materials frequently cause damage to air conditioning equipment, machinery, siding, insulation, etc. Besides damaging equipment, people around these areas are exposed to a potentially dangerous health-risk any time they work on or around the machinery. Nesting materials are often very flammable due to their construction of straw, twigs and dried droppings and when birds build their nests near air conditioning units and other machinery there is a definite risk of fire. Most bird droppings, especially pigeon and sea gull, fade automobile and other paint finishes by eating into the protective coating and the paint itself. The longer the droppings are allowed to sit on the paint, the more damage is done.

Chimneys and ventilation systems are favorite nesting spots for some birds and can potentially spread diseases through the air duct system, as well as blocking airflow. This can have horrible consequences like in 1995 when a family of five in Cleveland was killed by carbon monoxide poisoning when their fireplace exhaust was blocked by bird nests.

Attics of houses, apartments, and other buildings are favorite nesting places for many birds, especially pigeons. They enter through openings broken or never sealed off in the first place, and set up home in these protected areas, building nests and defecating. These areas have little or no exposure to sunlight or airflow, magnifying the potential spread of disease since bacteria harbored in the birds' excrement and nesting materials thrive under these conditions. Damage to the structure, insulation and any items stored in the vicinity can be costly, and often the foul odors that develop can be overwhelming. More than once the weight of droppings from a large number of resident birds has become so great that the ceiling has actually collapsed. In addition, droppings and nesting materials on or around a building send a message to neighbors that building is not properly maintained.

How to Handle Pest Bird Problems

First and foremost, bird infestations should be taken seriously, but not irrationally. When evaluating a health risk potential, look for the following: droppings or nesting materials inside air vents, birds around food or water containers/areas, or large amounts of droppings in enclosed areas. These are the types of situations where disease can spread. Remember, pigeons walking around a park bench is not necessarily cause for panic, but twenty birds living inside an attic could pose a health and damage concern requiring action.

Second, permanent barriers that actually deter birds from remaining at the site should be installed to keep birds from returning to the area. Examples of these products would be: bird netting, bird spikes, post & wire products, etc. Audio/ visual products such as screech owls, balloons, and audible sound products (not ultrasonic -- birds hear the same way humans do) can be effective against certain species (but not pigeons!) that are not nesting at the site. There are a number of companies and websites out there that specialize in bird control products such as Bird Barrier America, BirdSpikes.net and BirdBusters to name a few.

Third, when cleaning the site and installing bird control products, the proper precautions must be taken. Respirators, goggles and protective clothing should always be used when cleaning up bird sites, particularly in enclosed areas out of the sun with large amounts of droppings and nesting material.

Finally, once the birds are removed it is crucial to exterminate all the ectoparasites and thoroughly disinfect the site to prevent the migration of bacteria and parasites. Then you can be sure they will not move to a new host, like other animals in the area or even humans, once the birds are gone.

Bird control is something that should be planned in the budget if possible by building managers, as are other types of pest control. Generally, the earlier a problem is detected, the easier it is to solve, since the birds have not had a lot of time to become committed to the site. Control methods are available on the market that are effective and affordable, and installing them generally saves you time and money long-term, as it reduces the clean-up time and associated replacement costs which can mount quickly when a number of birds are present. Companies like Bird Barrier offer toll free phone consultations at (800) 503-5444 and have certified bird control product installers across the nation to assist in solving any bird problem.

How Bird Flu Kills

The bird flu virus is supposed to be really affecting the birds only. However, because of the nature of flu viruses that can be able to mutate and transfer from one species to the other. The bird flu virus that has been killing birds has now been affecting humans as well.

The good news is that bird flu virus has only killed few humans as of the moment. That?s why health officials are working overtime to prevent bird flu from becoming an outbreak. How the virus works on humans is still a complete wonder. There are still more and more studies undertaken to fully understand this virus.

What is known however is that there are 15 types of avian flu virus that affects birds. That?s why birds also have running noses as well, only theirs is a running beak (corny). The current outbreak of bird flu is caused by the H5N1 strain. This strain is very contagious and can cause rapid fatalities. This strain, unlike the others, can be transmitted to humans, which makes it deadlier.

Remember the SARS scare we experienced years back? Compared to Bird Flu, SARS is just an ordinary cold. Their symptoms are similar but the virus that causes them is completely different. SARS is also less contagious because the person infected can just be isolated.

There could be low pathogenic virus or high pathogenic virus that can affect birds. The low pathogenic virus can affect birds in minor ways only. Ruffled feathers and reduced egg production are some. Highly pathogenic virus cause severe diseases such as respiratory diseases. In domestic birds, when the symptoms appear, they die the same day.

Other symptoms of the bird flu on birds are: loss of appetite, nervousness like chicken little, coughing, sneezing, diarrhea, and depression. Yes, birds do get depressed and they might end up being suicidal, drinking your Prozac.

Just as in the birds, the highly pathogenic forms are the ones that greatly affect the humans as well. These highly pathogenic forms are what cause deaths in humans as well.

The incubation period of the bird flu on humans is still not yet known clearly. The ill effects might develop one to five days from exposure to the virus.

Sometimes, the only indication that a person has been infected is an eye infection or conjunctivitis. However, having conjunctivitis, you might only think that it?s ordinary sore eyes.

Then other symptoms that are common to flu are also developed. That?s why it really is hard to know that the person has been affected by the virus. Other symptoms include, cough, fever, and sore throat.

It will then develop to life threatening complications that include viral pneumonia, and respiratory failure and distress.

That?s why health officials and scientist are scrambling for ways to just make ways to prevent outbreaks. Because they would not want a person to have misconceptions that he or she only has ordinary flu, but is the already life-threatening bird flu.

The Situation With Vaccines For Bird Flu and Other Types of Flu

With everyone on the brink of panic regarding a bird flu pandemic, many are wondering if a vaccine has been developed and if not, why it has not. Vaccines have become a common and widely accepted way of dealing with various viral infections. Unfortunately, this is not yet a valid option for bird flu.

The primary reason an effective vaccine has not been developed for the strain of bird flu causing so much concern is simply lack of time. The process of vaccine development is long and arduous. The virus must be researched on a molecular level in order to create an effective vaccine. Although bird flu was first identified in 1997, the real concern for the disease did not come about until 2004, with the first real outbreak of the virus. Therefore, less than two years has been available to research and develop a vaccine. While vaccines have been developed, they are still in trial phases and hope to be complete soon.

To understand the other significant reasoning, you must first understand a little about bird flu and the threat it carries. As of yet, the virus is not a global, imminent concern. The reason for this is that the virus is now only transmittable through poultry and is not passed through human to human contact. Although many people have died, it is still primarily an Asian and European disease and has not reached pandemic proportions. However, that is likely to change soon.

As time goes on, the virus is mutating and is expected to become transmittable through human contact. When this happens, it will very likely spread quickly and devastatingly throughout all regions of the world.

Therefore, the second reason a vaccine has not yet been developed is due to the mutation of the virus. As of yet, the concern regarding the virus is not as drastic as it will be once mutation is complete. If mutation occurs, a vaccine will be essential to control the spread of the virus. However, a vaccine can not be developed to avoid the new version of the virus until it actually mutates. Any vaccine created before then will be useless on the mutated form of the virus as the molecular basis of the disease will change, altering the effectiveness of a vaccine.

It is believed that much of the groundwork has been completed for the mutated virus vaccine, but until mutation occurs, there will be no way of knowing its effectiveness.

Why Bird Flu Is Not A Pandemic

Most people are aware of the threat of bird flu and the possibility of it creating a pandemic, a worldwide epidemic of an infectious disease breaking out and affecting a large geographic region. Although the virus affects an extensive geographic region, this virus has not yet reached pandemic proportions.

According to the World Health Organization, in order for a pandemic to occur, three conditions must be met: the emergence of a disease new to a population, the agent affects humans and causes serious illness, and the agent spreads easily and sustainably among humans.

The first of these three, "the emergence of a disease new to a population" has occurred. Although bird flu is in no way a new disease, as it was first identified in the early 1900's, it was not infectious to humans until the late 1990's. Therefore, this particular strain has emerged "new to a population", being the human population, which was previously unaffected by the disease.

Likewise, the second criterion has been met, "the agent affects humans and causes serious illness". The virus has infected 131 people and killed 68. Therefore, the severity of the disease is apparent. H5N1 causes an exaggerated response in cytokines, hormones that regulate the immune system, therefore, limiting the effectiveness of the body's ability to fight the infection. This virus is also partially resistant to other cells of the immune system, making it especially resilient.

The third condition has not been met, however. At this point, the virus does not spread easily and sustainably among humans. Currently, the H5N1 virus is only transmitted from poultry to humans, and is not able to pass through human contact. Unfortunately, the virus is mutating and may be able to do so in future months, increasing the speed and efficiency in which it spreads.

Human to human transmission has been suspected, though not confirmed. Several isolated cases in which the cause of infection was not clear have prompted questions of the virus being passed through human contact. In particular, cases of nurses becoming infected after treating patients, children being infected with no poultry contact, and parents being infected after treating children with the disease. However, until confirmation is attainable that the virus has mutated to the point human transmission is possible, the third criterion will not be satisfied and H5N1 will not be classified as a pandemic. Likewise, the fatality rate will also have to increase to change the classification of bird flu.
