Avian influenza - questions and answers
With the onset of spring, not only last year's dog poop on the lawns begins to thaw, but also human stupidity. The avian flu hysteria begins a new round. "Vile swans spread the H5N1 Virus from China through Russia and Turkey to Western Europe. Mass death of waterfowl from bird flu! People are infected. Even cats will die! Death to swans and other waterfowl!"
Veterinary pharmacies and hospitals are attacking squadrons of grannies, demanding to protect their pets from a terrible fatal infection. Apocalypse! Avian flu, great and terrible, like Marilyn Manson! "
And no one knows that the increased horror of the same Marilyn Manson is only for those who look at him from the side of the auditorium and pay money. The rest, who peek out from behind the curtains and receive dividends from the spectacle, see what it is: a skinny, tattered creature with awkward makeup and stupid vinyl wings.
At the last international ornithological symposium "Anseriformes of Northern Eurasia", held from 5 to 10 October 2005 in St. Petersburg, and at the All-Russian Ornithological Conference in Stavropol in February this year, the problem of bird flu was seriously discussed. Let's try to summarize the available data.
Mysterious killer or news with forty-five years of experience?
For the first time, the avian influenza virus was isolated in 1902. During the 20th century, the incidence of various strains of group A was detected in a very large number of species of birds, mammals and humans. Some of the strains of this group are characteristic only for certain species, with some of them several groups of animals can get sick at once. Sometimes certain species can only be carriers, and they themselves do not get sick.
The virus of the H5N1 strain has been known since 1959, when an epizootic of chickens arose on a small farm in Scotland. In 1969, he caused an epizootic in Hong Kong. In 1979, it was found in wild waterfowl in the northeastern Caspian.
Thus, the novelty of the year is a "good old friend" for humanity.
Which ducks carry bird flu - wild or newspaper?
"A terrible infection from the east comes at us on the wings of migratory birds!" - with these words, associations arise with the medieval bubonic plague that came from the east with hordes of gray rats.
If this were so, then in the spring of 2005 a wave of the epizootic would go on a continuous front to the north. But throughout the history of the H5N1 strain, we see foci that are far apart across Eurasia. And in the past year - now the Novosibirsk region, now the Tula and Tambov, even in Finland in July, it seems, some seagulls with this virus were found, and in Romania - a dead gray heron. The winter outbreak of the disease in Turkey and Crimea, in principle, is located in the same geographic focus (Black Sea region) as Romania. And finally, the Western Baltic. And in the intervals between these points there is nothing contagious, these foci are not connected with each other.
Each large geographic grouping of waterfowl has its own flight paths and isolated wintering grounds. The exchange of individuals between these groups is extremely insignificant. Let's see: birds from our Far East and Eastern Siberia winter in eastern China, and it is there, according to the logic of newspaper events, that bird flu should get this summer. However, neither on Lake Khanka, nor on the lakes of the Amur floodplain, nor in Dauria (it is warm everywhere, there are a lot of people and poultry), nothing that pleases the yellow press has jumped out. Even if we assume that some significant part of the infected ducks wintering in eastern China suddenly went crazy and flew to nest in the Trans-Urals, then why did not any epizootics break out, for example, on Balkhash, in Semirechye? They could not pass these places of mass camps of migratory birds. And the heat is stronger there than in the Novosibirsk steppes and comes much earlier! Something doesn't grow together.
West Siberian birds winter in the Caspian Sea, the Persian Gulf and the Black Sea. They do not fly either through China or through the Tula and Tambov regions. Consequently, they could not bring anything there in one summer, since they meet with Central Russian mallards only at wintering grounds.
They could theoretically bring the virus to Crimea and Turkey in the fall. But they do not appear there until October, and already at the end of August in the Black Sea region (Romania) a dead heron (obviously of local origin) with H5N1 in the blood was found. This means that the virus has already wandered in this region.
Birds from completely different areas winter in Western Europe: the European North, tundra and forest-tundra, up to Taimyr. These two groupings never mix. From Turkey, waterfowl can only get to Egypt and Iraq, and by no means to the island of Rügen in the Baltic.
That is, we can safely say that in each focus of the disease, the virus has been present for fifty years, if not a hundred - from the moment of its inception. So, it is not a virus from China that spreads, but only unhealthy rumors and information ducks.
Where is the enemy's lair, who is he killing and why?
The H5N1 strain causes massive diseases and mortality only in poultry; in the wild, no large deaths from this virus have been detected. Only a small percentage of aquatic birds die, usually weakened by another infection. So in 1979-1982. in the northeastern Caspian Sea, according to the estimates of ornithologists of the Astrakhan Reserve, up to a million swans, geese, ducks and gulls perished. Some dead birds have been isolated with the H5N1 strain. But the cause of the tragedy was the massive poisoning of botulism toxins, and the flu acted as a "nice addition" for the emaciated birds. Even in 2005, only 15 dead wild ducks with this virus were found in the outbreak on Lake Chany in Western Siberia, but the deaths occurred for other reasons. And this with tens of thousands of dead poultry.
Why do the wild do not have such massive epizootics? First, because the immune system is stronger. Secondly, as mentioned above, H5N1 was discovered for a long time and existed, apparently, much earlier than the moment of its discovery, and natural populations perfectly adapt to any, even lethal at first, infection. It's simple: those who survive - transmit the signs of resistance to the strain to the offspring. Natural selection. There is no such selection in poultry!
Thirdly, nowhere in nature is there such superdense congregations of birds in one permanent place, as in chickens and ducks in a village courtyard. And such unsanitary conditions - too. The poultry house is usually a low, stuffy and cramped structure on chicken legs with microscopic blinded windows and a floor slimy from droppings. Yes, any stick of Koch will sell his soul for such a hacienda! Foolish from the "cultural" wintering and teeming with all kinds of bacteria, domestic ducks in the spring go in droves to the village pond or the nearest backwater of the lake, where they communicate with neighbors, share news and intestinal microflora. Can you imagine how many interesting things can proliferate in this nutritious broth, if you just bake the sun properly? A microbiologist's dream! And now, in waterfowl, poisoning with botulism, pasteurellosis, helminthic infestations, bacterial diseases and other delights begin.
On top of all the troubles in the exhausted organisms, the bird flu virus, which was peacefully dormant before, is sharply activated. And away we go, to the delight of the journalists languishing with heat and boredom. In support of the above, we note that not a single case of the disease has been detected in any large poultry complex in Western Siberia! Because they comply with sanitary standards and technology!
121 dead swan and dead cat on the island. Rügen. Is the lethality of the virus growing day by day?
The question arises: "Why did the winter surges of H5N1 occur in Turkey and Germany?" To answer the question, let's look at the situation a little more broadly. Over the past twenty years, there has been an extremely strong climate warming in Europe. During the same period, European environmentalists enforced many laws and programs to make life easier for waterfowl.
Due to these two reasons, the number of many bird species has increased manifold.
And suddenly, after such prosperity, unprecedented frosts and snowfall fall on dense mass concentrations of wintering birds! And so throughout Europe!
During the winter cold in the Baltic, there have been cases of deaths before. Swans and ducks died in thousands from exhaustion in Denmark, and off the coast of Pomerania, and even on the Estonian seaside (1983-85). But nobody tested them on H5N1 - there was simply no such panic "anti-bird" campaign.
This year the frosts were unprecedented, and the number of birds killed from starvation is expected to reach tens of thousands. Any birdwatcher will tell you that. But no one officially talks about these numbers. Speak only about 121 dead swans with the H5N1 virus in their blood. And this is done to create the illusion that the birds died from it, and there is "an unprecedented death of wild birds from the flu."
The unfortunate cat found on the street is also added here! Listen, stray cats always feed on all sorts of filth and raw bird meat! So there is nothing surprising in the presence of the virus in her blood. And in such frosts, she could die from other more prosaic reasons!
Will the flu kill humanity?
A hybrid avian-human flu is possible. In theory. In practice, with regard to the H5N1 strain, in its entire history from 1959 there was not a single case of disease and death of a person until 1997. There were no such cases in 2005 in Russia. Think: up to 80 thousand infected poultry in Western Siberia and not a single human disease, despite constant and close contacts at peasant farmsteads!
At the same time, according to oral reports of ornithologists who worked in the areas of epizootics, our peasants ate the infected bird with might and main, and during slaughter they did not always comply with the prescribed norms. Well, there are no effective (active) human antigens in this strain!
What will happen?
Epidemiologists will face the enemy fully armed - the development and testing of vaccines have been successfully completed. But the tragic consequences of unhealthy media hysteria can be palpable. For example, the decline in agriculture caused by a panic decline in consumer demand.
Most importantly, wild birds may be harmed. Already in 2005, in some places barbaric shootings were observed, sanctioned by a number of local authorities. Such a measure does not lead to anything good - healthy birds were destroyed in mass, completely innocent of the epizootic caused by human carelessness. After all, poultry almost exclusively get sick and transmit the infection to each other. And wild waterfowl, frightened by the shooting, begin to concentrate en masse on small safe areas, where the likelihood of the virus spreading sharply increases. In addition, the birds that died during the shooting become a real source of infection for both water bodies and corpse-eating animals.
Bird watchers everywhere demand that migratory birds be left alone. The authorities seem to be listening, and in some places they have already banned spring hunting. But instead they create detachments of shooters to shoot birds in "flu-hazardous places". And will anyone keep an eye on all the headless alarmists and poachers who want to burn their fill under the guise of fighting the "universal infection"?
This is how someone will earn huge money on this unhealthy hysteria, and huge irreparable damage will be caused to nature. Waterfowl already suffer from massive, often poaching, hunting every year.
A brief conclusion for grandmothers with cats and lapdogs
Dear ladies, cases of infection of cats and dogs with bird flu are so rare and exotic that you can be completely calm about the fate of your Murziks. If you let them out into the street, then they will die only from some other infection or under the wheels of a car. There is plenty of both in our city. Almost all newspaper facts are so unverified and doubtful that one does not want to dwell on them. And as for the dogs - so far not a single case of infection with bird flu is known. So, get vaccinated from the Olympics and listen to stupid radio less!

How important is gardening and horticulture for a person
Any gardening, no matter what the scale, is definitely a worthy occupation, regardless of the skill level. Being a gardener means constantly learning, learning something new, experimenting.
You can treat gardening in different ways:
- get carried away with it as a hobby
- engage in professional activities.
This activity can bring not only pleasure, but also profit. For some, a garden, a vegetable garden, a dacha is an opportunity to take a break from the bustle of the city. Someone has to earn money by growing and selling vegetables and fruits. And in the countryside it is generally an integral part of life.
Is it possible to get bird flu
The influenza A subtype, which causes disease in birds, is also dangerous for humans. Infection occurs through direct contact with birds carrying this virus, their feces or objects that they constantly touch.
The virus is known to die from high temperatures. Therefore, when heat-treating poultry meat for more than an hour, it is not dangerous to eat it. Eggs mixed with blood cannot be eaten. Eggs that have not changed color should be boiled for at least ten minutes. Before doing this, they should be washed to get rid of the infection from the shell. Eating raw eggs is very dangerous.
New bird flu recorded in Russia
A new bird flu virus was found in the Novosibirsk branch of Rospotrebnadzor. The emergence of a new H5N8 infection was announced yesterday, February 20, by the head of the department, Anna Popova.
The virus was caught by seven employees of a poultry farm in southern Russia. The workers bore it easily. In December 2020, an outbreak of influenza among birds was recorded there. The most encouraging fact is that no cases of human-to-human transmission have yet been found. Whether it is possible to catch the infection by eating the meat of an infected bird has not been reported.
In 2020, an outbreak of highly pathogenic H5N8 influenza was observed in birds in several countries: Denmark, France, Germany, Ireland, the Netherlands, Sweden and the United Kingdom. Most of the cases involved wild birds, mostly duck birds. There were also several cases of infection in poultry farms. China has already reported cases of human infection with the closely related type of avian influenza, H5N6. The Belarusian authorities have not yet made statements about a new bird flu in the country.
Medicine in the USSR and now: a comparison. Achievements of Soviet medicine. Famous doctors of the USSR
You can often hear that medicine in the USSR was the best in the world. Is it really? The statistics are relentless: now only 44% of Russians, that is, less than half, consider it necessary to consult a doctor for any ailment, the rest do their best to avoid people in white coats. Two-thirds of the population is categorically dissatisfied with the quality of medical services, complaining of inattention, rudeness and incompetence of doctors and nurses. And how was it in the USSR? Let us compare Soviet and modern medicine, and then briefly touch upon the topic of achievements and outstanding doctors of the times of the USSR.
BIRD FLU - is it dangerous?
Avian influenza was first described by the Italian veterinarian Eduardo Perronchito [it] in 1878 under the name chicken typhus. Perroncito reported an outbreak of a highly contagious disease affecting chickens on farms in the vicinity of Turin, Italy.
For some time, avian influenza was confused with Newcastle's disease, but after the etiology was established, the latter was called pseudo-plague or Asiatic avian plague, and avian influenza - classical or European avian plague.
Outbreaks of European bird plague regularly occurred at the beginning of the 20th century in the countries of Europe, Africa and Asia. In 1925, the disease came to North America. In the second half of the 20th century, 18 large epizootics were registered only abroad.
In 1901, the viral nature of the pathogen was established, but only in 1955 it was proved that the virus that causes "bird plague" is an influenza virus.
The modern name - avian influenza - received this disease only in 1971. With regard to the most dangerous forms (for example, caused by the H5N1 strain), the term highly pathogenic avian influenza is also used.

Re: Caution! Bird flu!
Don't worry, there is more than one factories. In 21 days, it will work (quarantine). Everyone will be burned, the ditch has already been dug.

Re: Caution! Bird flu!
100% sure all property is insured
they don't care about the flu, they don't get sick. But pigeons and carriers themselves get sick. Hope for crows - they will eat the weak and the sick, in fact, for this they serve - orderlies of birds, feed the crows

Re: Caution! Bird flu!
Quarantine was introduced at the Kostroma poultry farm due to a dangerous virus.
The bird flu virus was detected at the Kostromskaya poultry farm in Nikolskoye. In this regard, quarantine was introduced at the enterprise, the governor's press service reports.
Residents of the region are advised to limit contact with wild birds, and eat poultry and eggs only after heat treatment: cook the egg for at least 10 minutes, meat for at least 30 minutes at a temperature of 100 degrees.
Invalid domain name.
It seems to me that this factory will be fine. After all, they are in the top 20 Poultry Farms in Russia!
Plus, they have their own bank.
The entire poultry farm is sent to the burial grounds. Kick-ass looks like her. Interestingly, the crows, pigeons, and other birds, who ate there for free, will lay themselves in the burial ground or rush into the city to feast on at last. In a strange way, they mentioned the first case of influenza in Kostroma. As a rule, half of the city will get flu with a diagnosis of acute respiratory infections, until the authorities officially recognize this fact, and here one case and oppa is the flu.
An acquaintance of mine works there. He says that in January they will populate the workshops with new chickens. So everything that the media writes is nonsense. There are live answers from people working there
