The climate conditions are rather different: from arctic and moderate to continental and subtropical. Our country is one of the richest in natural resources countries in the world: oil, natural gas, coal, different ores, fer- rous and non-ferrous metals and other minerals. The Russian Federation is a multinational state. It comprises many national districts, several autonomous republics and regions. he popula- tion of the country is about 140 million people Moscow, the capital of Russian Federation, is the largest political. scientific, cultural and industnal center of the country and one of the most beautiful cities on the globe. Russian is the official language of the state. The national symbols ofthe Russian Federation are awhite-blue-red ban. ner and a double-headed eagle The Russian Federation is a constitutional republic headed by the president. The country govemment consists of three branches: legisla- tive, executive and judicial. The President controls only the executive the government, but not the Supreme Court and Fed branch of eral A The legislative power belongs to the Federal Assembly comprising two chambers: the Council of Federation(upper Chamber) and the State Duma(lower Chamber.

thousands of years people lived in harmony with environment and it seemed to them
that natural riches were unlimited. But with the development of civilization man’s
interference in nature began to increase.Every year world industry pollutes the
atmosphere with about 1000 million tons of dust and other harmful substances. Many
cities suffer from smog. Vast forests are cut and burn in fire. Their disappearance
upsets the oxygen balance. As a result some rare species of animals, birds, fish and
plants disappear forever, a number of rivers and lakes dry up.The pollution of air and
the world’s ocean, destruction of the ozone layer is the result of man’s careless
interaction with nature, a sign of ecological cities. Environmental protection is of a
universal concern. That is why serious measures to create a system of ecological
security

notice of. Twice a day, with predictable regularity, the pot boils over. Whenever you look it’s people, people, people. The trains which leave or arrive every few minutes are packed: an endless procession of human sardine tins. The streets are so crowded, there is hardly room to move on the pavement. The queues for buses reach staggering proportions. It takes ages for a bus to get to you because the traffic on the roads has virtually come to a standstill. Even when a bus does at least arrive, it’s so full, it can’t take any more passengers. The smallest unforeseen event can bring about conditions of utter chaos. A power-cut, for instance, an exceptionally heavy snowfall or a minor derailment must always make city-dwellers realize how precarious the balance is. The extraordinary thing is not that people put up with these conditions, but that they actually choose them in preference to anything else. Large modern cities a too big to control. They impose their own living conditions on the people who inhabit them. City-dwellers are obliged by their environment to adopt a wholly unnatural way of life. They lose touch with the land and the rhythm of nature. It’s possible to live such an air conditioned existence in the large city that you are barely conscious of the seasons. A few flowers in a public park (if you have time to visit it) may remind you whether it’s spring or summer. A few leaves clinging to the pavement may remind you it is autumn. Beyond that, what is going on in nature seems totally irrelevant. Tall buildings blot out the sun, traffic fumes pollute the atmosphere. Even the distinction between day and night is lost. The flow of traffic goes on unceasingly and the noise never stops.

from birds to humans easily, the severity of the infection of H5N1 in humans is frightening. The virus has killed every second person infected by it. These cases were reported in perfectly healthy individuals who had no past history of infections. However the greater concern for the world is the POSSIBILITY THAT THE VIRUS MAY MUTATE (UNDERGO ANTIGENIC SHIFT) AND CREATE A FORM THAT MAY SPREAD FROM HUMAN TO HUMAN. Such a strain of virus may result in a pandemic, killing millions of people worldwide.

Is Consumption Of Poultry Birds Safe?

Yes, it is safe to consume THOROUGHLY COOKED poultry products. The H5N1 virus is sensitive to heat and gets destroyed by normal cooking temperatures of 70- 100 degree Celsius. If meat from poultry birds and eggs are cooked properly, the virus will be destroyed. Just make sure that no part of the meat remains raw or uncooked.

How Big Is The Risk Of A Pandemic Breaking Out?

The world had to face a Bird Flu Pandemic, thrice in the twentieth century. In 1918-1919, "Spanish Flu" killed anywhere between 20 million to 50 million people (exact figures not known), including half a million in the United States alone. The "Asian flu" in 1957-58 killed 70,000 in the United States and in 1968-1969, the "Hong Kong flu" killed 34,000 in the USA.

Currently the risk of H5N1 strain leading to a Pandemic is high. The virus is spreading fast to new areas and the efforts made to curtail it have proved inadequate.

Domestic ducks have now become a "reservoir" for the virus. They are acting like a carrier for the virus - their bodies carry the virus without showing signs of any infection. Infected ducks then release large quantities of the virus in pathogenic form in their excretions spreading the virus to other birds or humans. This has made detection of the virus difficult especially in rural areas.

According to health experts, the virus has already met the first two prerequisites for starting a pandemic. First it has attained a form, for which humans have no inbuilt immunity; and second, it has proved pathogenic enough to cause serious illness and death in humans.

The present risk of a pandemic is very high. The only factor that has prevented a pandemic so far is that the virus has not mutated into a form that would allow it to transmit efficiently from one human to another. Once such a genetic change takes place for the virus, a pandemic will be inevitable. The first signs of such a reassortment will be presence of the clusters of patients with flu symptoms, closely related - both in time and space. This would be a clear indication of virus having the ability to transmit from human-to-human.

Currently no vaccine has been developed for fighting H5N1 strain. Simultaneous work is being done in many countries for developing a vaccine, but no success has been achieved. The exact virus that may cause the pandemic cannot be predetermined. Thus mass production of vaccine before the pandemic starts is ruled out. The worldwide manufacturing capacity is inadequate to match the sudden demand surge during a pandemic. The best that scientists can do is to carry out a study and determine the smallest amount of antigen per dose that will provide sufficient protection and thus maximise the number of vaccines produced.

What Are The Precautions Necessary To Prevent A Pandemic?

The logical first step is to control the disease from spreading among birds, but this seems a difficult task now. Bird Flu has become a bird epidemic in many parts of Asia and is spreading fast.

The Next step is to prevent the disease from getting passed on to humans. People who come in close contact with birds (like poultry farmers) are advised to keep a close watch on the health of birds, notify any sort of sickness in birds to the health authorities and avoid direct contact with sick birds in all cases. (Ducks have become a reservoir for the virus and may not exhibit signs of sickness even if they are carrying the virus.)

In case the flu becomes a pandemic, most countries of the world will be affected. In such a scenario, the best preventive measures would be personal hygiene, avoiding crowded places and staying away from raw meat and eggs.

A flu shot does not prevent bird flu, but it can protect a person from other forms of flu and avoid complications. Persons above 65 years of age, children, health services workers, people with chronic respiratory disorders, travellers to flu affected countries and pregnant women may consult a doctor regarding flu vaccination.
