EVOLUTIONARY BIRD FLU (2)

avian flu 2

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 :

EVOLUTIONARY BIRD FLU

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.

Tool to Prevent Bird Flu

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.

PREVENTING from BIRD FLU

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.

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.

H5N1, New Virus?

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.
