It appears that it did evolve once it was in Europe. The first wave of it hit the soldiers in the spring. It was known as the 3 day flu because large numbers of them caught it, were sick for 3 days and then recovered.

Then it went unnoticed until around September 1918 — when it spread throughout the world and in 3 months killed many more people than the war itself. From at peace Spain (which was unfairly blamed for it) to the South Pacific to remove Eskimo villages in Alaska.

Perhaps the deadly 1918 flu had its deadly origins for BOTH reasons :

1. It was a mutated avian flu that people did not have any acquired immunity for.

• 2. Wartime conditions encouraged it to retain and/or increase its lethality, by rewarding it for disabling and killing soldiers so fast and easily.

What does this mean for bird flu today?

We already know it’s a mutated avian flu we have no acquired immunity for. It kills over half of its human victims.

There is no major, intense war underway — but many people in large megacities of the developing world from Rio to Calcutta live in extreme density. One sick person lying in the corner of a corrugated iron hovel could infect many close family members and neighbors. If a pandemic struck, many would be transported to large and overcrowded medical centers.

In such conditions, a bird flu mutation would likely retain or evolve its extreme lethality.

And what if it was “only” as lethal as the virus that caused the 1968 “Hong Kong” virus?

According to the CDC, the 1968 virus would today kill 2 to 7 million people around the world. From 89,000 to 207,000 people just in the U.S. That would not be a worst case scenario but it would certainly cause a lot of fear and concern.

Therefore, bird flu does not have to evolve into a strain as deadly as 1918, to pose a threat to millions of people around the world. Even without a major world war, we are at risk from a bird flu pandemic.

According to evolutionary biologist Paul Ewald, author of Evolution of Infectious Disease and Plague Time: How Stealth Infections Cause Cancers, Heart Disease and Other Deadly Ailments (both great books well worth reading), the 1918 flu was so much more lethal than ordinary flu because it appeared and evolved at the Western Front of World War I Europe’s brutal trench war.

The more advantageous it is for infections to keep us alive and feeling well enough to walk around, the safer they are. The common cold is irritating but we can still go to work with it — the better to sneeze and spread cold germs to our co-workers.

The more advantageous it is for infections to destroy us, the more they will destroy us. Malaria makes us so sick because it spreads by mosquitoes — who find it easier to bite people who’re too sick to swap the mosquitoes. Who then go spread the infection to a healthy person.

During the 1918 flu, soldiers in Europe lay sick in crowded trenches where they easily spread the flu to other soldiers even though they were too sick to walk and many soon died. When transported to medical care, they were crowded into trucks and train cars with other sick and wounded soldiers. And arrived at military hospitals crowded with more sick and wounded soldiers.

Therefore, the 1918 flu virus had every evolutionary incentive to evolve into a strain highly lethal to people.

But is that the whole story? According to Ewald, we are not in danger of a bird flu pandemic — or at least, not one as deadly as 1918 — because there is no similar war going on today.

So should we all forget about bird flu and start worrying only about Iran?

Ewald uses sources from the 1940s that give France as the origin of the 1918 flu.

In The Great Influenza: The Epic Story of the Deadliest Plague In History John M. Barry discusses the work of Dr. Edwin Johnson, editor of THE JOURNAL OF INFECTIOUS DISEASE, who studied the 1918 soon after it happened and published EPIDEMIC INFLUENZA in 1927.

Dr. Johnson also discards the theory (that some have given) that the 1918 flu originated in China and spread to Europe via imported laborers. Yet he also could not find evidence that it started in Europe.

In Haskell County, Kansas, the winter of 1917-1918 was hard. Many people came down with a flu that was unusually serious. We don’t know exactly how many of Haskell County flu victims that winter died, but it was enough to alarm the local doctor. He was so concerned about the number of local and deadly cases of flu that he wrote an alert to the government.

Of course, that didn’t stop the government from drafting young men from Haskell County — who were sent to Camp Funston for training before shipping them off to France.

So it’s quite possible that the 1918 flu first infected people in Haskell County, Kansas.

Precaution is the best tool that we have to prevent a worldwide pandemic. Taking simple steps such as washing your hands frequently and sneezing and coughing into tissues can go a long way in preventing the spread of germs and viruses. It is also important to make sure that you stay up to date with yearly flu shots. The shot won’t prevent Avian Flu, but it will help to ensure that you don’t come down with Influenza. If someone were to have Influenza and then contract the Avian Flu at the same time, that would be the perfect mix for mutating the Avian Flu strain. By staying current with your shots, you will help minimize the risk of that happening. If you are visiting a foreign country that has had cases of Avian Flu it is important to use care and precaution. Stay clear of areas that host wild birds or birds for sale in open markets. Also, make sure that all of the food that you eat has been cooke
H5N1 virus symptoms are very similar to other symptoms of Influenza. Symptoms include fever, sore throat, malaise, and coughing. It can progress to Pneumonia and other serious conditions. A person who has contracted bird flu will need a lot of fluids and should be treated by a physician immediately. If the condition is untreated, it can lead to death.

Currently, the Bird Flu has been affecting Asia and Europe. The rest of the world is keeping a close eye on this illness to make sure that it doesn’t cross any more borders. Avian influenza, though common with wild birds, can devastate domesticated birds swiftly and quickly, completely eradicating all that were infected with the virus. The potential crisis is in the fact that humans do not have built in immunities to this virus. If it mutates and infects humans, they would not be able to fight it off without medical intervention. Since the strain hasn’t mutated yet, there isn’t a medicine that can cure it. The only way we can fight this potential crisis is through prevention.

There are many ways of preventing this particular disease from occurring in chickens and other poultry farms. Firstly the virus is usually spread by native birds who usually have an immunity to the bird flu virus. Most poultry stock are not bred with this immunity and therefore when they come in contact with native birds, they may pick up the virus and spread it throughout the whole flock. This is probably the most common reason how the virus is spread.

To prevent this from occurring, farm owners must do everything in their power to prevent outside contact from other birds with their livestock. This is one of the reasons why chicken farmers choose to keep their chickens caged because they are afraid that their flock may become infected with if not the bird flu virus, but another deadly disease that could destroy their whole flock of poultry.

How does bird flu ?

The bird flu virus is a strain of influenza that appears to affect only avian species or birds. So why is it that there have been so many humans deaths associated with bird flu? The answer is that infact it isn’t the actual bird flu virus that infects humans, but a mutation of the virus. What actually happens is the virus mutates into the human strain of influenza that is super deadly. This of course doesn’t always happen but when it does, it can be catastrophic.

Throughout history there have been several cases of bird flu outbreaks that have been known to have killed hundreds of thousands of people. The latest cases are coming out of South East Asia, where there were several deaths due to the bird flu virus. Many experts believe that the most scary thing about bird flu is not that it is so deadly, but that it has the potential to spread so fast and maybe to a point where it could become uncontrollable. Whatever the case, people must do everything they can to prevent it from occurring in the first place.

The bird flu virus is one of the most deadliest in the world and has taken many lives over the last century and a half. This virus is better known as avian influenza and is derived from an influenza virus from birds. When there is an outbreak of the avian flu virus, vast numbers of poultry including chickens and ducks have to be slaughtered to prevent the virus from spreading beyond the poultry and into the realm of humans.

The most recent breakouts have occurred in South East Asia and more particularly Indonesia, where many people died in a very short period of time. Luckily modern medicine is far more adept at treating influenza viruses these days. If the same breakout had have happened back at the beginning of the 20th century many more people would have died and its potential to spread across countries would have been greater. This of course did happen several times nearly 100 years ago and many people lost their lives.

Well first of all measurements are being taken to prevent poultry from becoming infected in the first place. Poultry farms are usually the beginning of any outbreak. Why? Well, poultry like chicken and ducks sometimes become infected by wild birds who of course contain an antibody that protects them from the Asian bird flu. This of course doesn’t mean they still can’t carry the virus and when a bird kept in captivity comes in contact with a carrying wild bird, it then becomes infected. That bird then passes it onto the rest of the birds on the farm and before you know it, there’s an epidemic.

If this happens, there is usually a mass culling of poultry to prevent any chance of Asian bird flu spreading any further. Unfortunately in many cases, infected chicken is sold to consumers and that’s where it can become a problem for people. The virus has the potential to mutate into a disease that harmful for humans and that can also be spread from human to human.
here is a deadly disease that has and still is sweeping nations across South East Asia. It’s now beginning to be known as the Asian bird flu. So what is it and how does it affect people? Well the Asian bird flu is a virus that is spread by birds, hence the name bird flu. It’s a type of influenza virus that can spread like wildfire when given the opportunity.

So you’re wondering how Asian bird flu is contracted by humans if it’s a strand of influenza that only affects birds? Well unfortunately, bird flu is like many other strands of influenza being that it has the potential to mutate into other strands when placed in the right environment. This of course has occurred many times and has resulted in catastrophic proportions on the human population.

Generally Bird Flu, the viruses do not affect humans, or cause mild illness at worst.
Diarrhea and Abdominal Pain: Diarrhea and abdominal pain has been a symptom in some patients, but not all of them. Watery diarrhea may be a symptom in bird flu cases, but is not a common symptom in regular flu. Diarrhea comes before respiratory symptoms. Two young patients had encephalitis and diarrhea without any respiratory symptoms.

The name H5N1 refers to the type of proteins found in the protein coat of the influenza virus – haemagglutinin 5(H5) and neuraminidase 1 (N1). There are dozens of different proteins that can be present, so that flu viruses called H1N1, H1N2, and H3N2 etc are also known.

Officials of the Kano state avian flu control committee detected the presence of Avian flu among 16,000 chickens on a farm a few days ago, a month after the area was declared free of the virus.
Avian influenza cannot be diagnosed by symptoms alone, so a laboratory test is required. Avian influenza is usually diagnosed by collecting a swab from the nose or throat during the first few days of illness. This swab is then sent to a laboratory, where they will either look for avian influenza virus using a molecular test, or they will try to grow the virus. Growing avian influenza viruses should only be done in laboratories with high levels of protection. If it is late in the illness, it may be difficult to find an avian influenza virus directly using these methods.

The virus has been identified in 12 states, including the largest city, Lagos, as well as around the federal capital, Abuja, since it was first confirmed in Nigeria four months ago.

Avian influenza infection in domestic poultry causes two main forms of disease that are distinguished by low and high extremes of virulence. The “low pathogenic” form may go undetected and usually causes only mild symptoms (such as ruffled feathers and a drop in egg production). However, the highly pathogenic form spreads more rapidly through flocks of poultry. It is the highly pathogenic form of H5N1 that concerns scientists.
Avian flu passes from birds to other birds, but there have also been human cases. As of January 2007, the World Health Organization (WHO) had confirmed 270 cases of H5N1 in humans in Azerbaijan, Cambodia, China, Djibouti, Egypt, Indonesia, Iraq, Thailand, Turkey and Vietnam, leading to 164 deaths.

Avian influenza (or bird flu) is a highly infectious disease affecting many species of birds, including chickens, duck, turkeys and geese. It can affect commercial, wild and pet birds. There are 15 types of bird flu, but the type that is causing concern at the moment is the deadly strain H5N1.
