The bird Influenza virus is a contagious confusion to that all species of geese are exposed. It vary from milder forms to a awfully exacting stage that consistently leads to death. Some bird species are more impervious to the virus than others but the real jeopardy of the Bird corruption is the contingency of transmission to humans.
There are 16 types of bird flu, but the type that has caused concern in recent years is the deadly H5N1 strain.
It is often referred to simply as bird flu or avian influenza though it is only one subtype of avian influenza causing virus.
Bird flu has a savagely high mortality rate, but fortunately is not transmissable person to person.
Also known as bird flu, is an infectious disease caused by a virus that lives naturally in wild birds.
Diagnosis is based on the onset of symptoms within 10 days of travel to a province with documented bird flu in poultry or humans.
The strain of bird flu virus found in Asia has not been found There have been no human cases of the flu However, it is possible that travelers returning from affected countries in Asia could be infected.

Flu activity seems to have quieted down recently, for which we can all be thankful. But the flu season is not over yet. Influenza is still out there.

Many states are reporting flu activity, which still remains a threat. Seasonal influenza usually peaks in February and March and can continue as late as May. So increased activity from the seasonal influenza, the H1N1 flu or both is still possible.

We need to remember the 1957-58 pandemic, when flu activity decreased in December and January. Thinking the worst was over, officials relaxed their push to get people vaccinated. When flu activity significantly returned in February and March, many were hospitalized, and deaths increased, as well. This could be a good lesson for us today.

So far during this flu season, most activity has been attributed to the H1N1 virus, which first appeared in April.

By the middle of November, the United States had reported roughly 47 million H1N1 flu cases. This resulted in well over 200,000 hospitalizations and caused nearly 10,000 deaths. About a thousand of those deaths were in children younger than 18, a number of whom were healthy before they caught the flu. That is why it is important not to take this disease lightly.

Although I think everyone would benefit from the flu vaccine, it is especially important for certain groups. You should be vaccinated if you:

• Have a chronic illness such as asthma, heart disease, or diabetes.

• Are pregnant.

• Are 65 years or older, and therefore are at increased risk of complications.

• Care for or live with a baby less than 6 months of age, as these infants are too young to be vaccinated for influenza.

Children who are 9 years old or younger need two doses of vaccine about a month apart; however, waiting more than a month between doses does not seem to decrease the effectiveness of the vaccine. Adults need only one dose.

Regarding popular worries about side effects of the H1N1 vaccine, data from the established surveillance systems would indicate that H1N1 has a safety profile similar to that of the seasonal flu vaccine. No significant pattern of adverse health events have been seen with either of the vaccines.

The bottom line is that although flu activity has died down this past month, the season is not over. It is still important to get vaccinated and be prepared for a possible increase in flu activity, which could occur between now and May. At this time, there appears to be enough vaccine for anyone who wants it.

I would like to thank the Palo Alto Medical Foundation’s Santa Cruz Incident Command Committee for supplying some of the information for this article.

CDC has revised the death toll for the H1N1 pandemic to almost 10,000 people since April, a significant jump from mortality numbers released last month. A month ago, the CDC estimated that only about 4,000 had died. CDC also noted that:

• 50 million Americans, one sixth of the country, had caught the disease
• 213,000 people had been sick enough to be hospitalized

Several flu experts said they were not shocked by the sudden jump because the new figures were as of Nov. 14, when this fall’s wave of swine flu cases was reaching its peak. The previous estimate of 4,000 deaths, issued last month, was only through mid-October. By next month, deaths should not have risen quite as abruptly because the fall wave is tapering off and hospitals have fewer people in intensive care, experts said. “I’m not surprised,” said Lone Simonsen, an epidemiologist at George Washington University’s School of Public Health. “This includes most of the fall wave.”

How many will ultimately die of the H1N1 flu depends heavily on whether there is a third wave in January, as happened in the 1918 and 1957 pandemics, and on whether the virus changes to be more lethal or drug-resistant. Predicting that requires a crystal ball.

Dr. Thomas R. Frieden, Director of the CDC said about 85 million doses of the H1N1 vaccine were now available. Some states have so much that they are asking that everyone over six months old get vaccinated, not just high-risk individuals. There is “still a good window of opportunity” to get vaccinated, Dr. Frieden said, adding that he plans to get the nasal spray vaccine himself “in a few days.”

Mutations making the flu more lethal and drug-resistant have been spotted in many countries, but thus far only in small numbers of isolated cases.

Michael T. Osterholm, director of the CIDRAPat the University of Minnesota, agreed that trying to guess how many would die by spring was “calling the score at halftime.” Mr. Osterholm was troubled by recent predictions that the pandemic would be the mildest on record.

“So the C.D.C. says 50 million have been infected so far,” he said. “Another 50 million have been vaccinated. And maybe 20 million have got innate immunity because of their age. You do the math — that’s 120 million who are immune out of 320 million, so two-thirds of the population is still not immune. It’s amazing how many people are acting as if this is all wrapped up. The numbers could still go up dramatically.”

Dr. Arnold S. Monto, a flu expert at the University of Michigan School of Public Health, said the flu might reach the lower end of a widely publicized forecast made in August by the President’s Council of Advisers on Science and Technology, which predicted 30,000 to 90,000 deaths.

Deaths appear to be lower than expected, Dr. Monto said, partly because young victims are better able to tolerate the aggressive drug and oxygen therapy used in hospitals to save those with overwhelming pneumonia. Flu deaths are hard to count because tests are inaccurate and some people die without being tested. In addition, some die of heart attacks, emphysema or organ failure, though flu triggered their illness. About 36,000 die in a typical flu season, according to a well-known 2003 study, but epidemiologists used different methods to calculate the 10,000 swine flu deaths, said Dr. Beth P. Bell, of the CDC.

In 2003, they counted winter deaths over a decade; this season’s model is based on lab-confirmed flu hospitalizations. The old method would probably conclude that more than 10,000 had died thus far, but it is impossible to know how many, Dr. Bell said. Dr. Frieden said Thursday that all the experts he consulted were divided over whether the country would have a January wave. “Half think we will,” he said, “and half think we won’t.

Also, Dr. Frieden noted that American Indians and Eskimos had died at four times the rate of other Americans. That is probably not because of genetic differences, he said, but because of poverty and childhood malnutrition, among other factors. (Canadian Indians have also had high death rates. But so did Australian aborigines, who have similar rates of poverty, isolation and underlying disease but are genetically distant from North American Indians.)
