0 The cases of infected with bird flu in China grow , but there is no danger of an epidemic.

On Tuesday, January 28 , the total number of people infected in China for 2014 H7N9 virus reached 100 . However, experts say there is no danger of an epidemic during the weekends for the most important holiday in the country - the Spring festival , or Chinese New Year .

In recent days, almost daily reports of new cases of people infected with the virus H7N9. On Tuesday, January 28 , in the eastern Zhejiang province were reported 4 new cases that number this year has reached 53 people .

According to the initial infection with the virus H7N9, which was announced in February 2013, so far in mainland China they are already over 245 people , they died by Tuesday, January 28 are 56. In May last year the cases declined , but as happens generally with flu virus during the winter months at the end of 2013 cases of people infected with the new strain again started to increase. In January according to the National Center for Control and Prevention of Disease , the number of people infected has exceeded 100, and the deceased 19.




Despite rapid growth in the number of people infected with bird flu , authorities say that the likelihood of a major epidemic remains small, given that the transmission of the virus from person to person has been sporadic.

Feng Dzadzyan is deputy director of the National Center for Control and Prevention of Disease .

" In epidemiology work with an index that defines the diseases that can be spread among the people. If the disease can spread , the index will be greater than one. This means that the disease can be transferred from one person to more . However, when the index is below unity , the disease will not spread on a large scale . Our analysis of the H7N9 virus and its index by 0.09 points show that there is a serious danger of the outbreak . "

WHO also said that so far there is no evidence of " stable " transfer of the virus between humans. Chinese authorities take draconian measures to limit the reach of people living birds. Cities in Hangzhou , Ningbo and Dzinhua trade in live birds was banned and Hong Kong , where one paid Guangdong Province chickens was discovered virus H7N9, were slaughtered 20,000 birds. authorities in SAR banned imports of live poultry from mainland China and sell them for three weeks.

Shu Yuelun is director of the National Center for flu. According to him, there is no danger of bird flu epidemic during the Spring holiday, which is a peak period travel in the country.

" The disease is spread primarily from birds to humans. During peak travel for spring holiday, regardless of the massive gathering of people in one place , no particular risks of spreading disease . So exodus will not lead to the outbreak of the epidemic. "

He added that this should not soothe ordinary citizens. Authorities will step up monitoring for potential virus carriers in key transportation hubs , airports, railway stations and bus stations . Passengers who were with temperatures above 38 degrees and have had contact with live birds will be required to undergo a medical examination before you set off.

China has made progress in developing a vaccine against H7N9. Hunanskata company " Hualan Bioengineering " in early January announced that the vaccine being developed by its subsidiary " Hulan Biobakterin " has passed initial approval of health authorities , but it will take time until the produce it

The meeting with the media, dedicated to current concerns about bird flu , Chief Executive of Hong Kong Lan Chunin , questioned whether residents should continue with the habit to buy live poultry markets . According to him, this practice should be reconsidered , since even a single case of bird flu in Hong Kong, forcing residents to pay a social price for their health.

Lan Chunin added that all the Hong Kong society, including poultry dealers , restaurants and other sectors should pay attention to the advice of the authorities and personal hygiene, as well as to comply with health orders.

Every time after registration of a case of infection with H7N9 authorities SAR killing thousands and even millions of birds to ensure that the infection does not spread .

Last Sunday , Deputy Prime Minister of China Liu Yandun also spoke specifically on the topic of avian flu , indicating the need for coordinated efforts to prevent and control infection .

Under the plan for the diagnosis and treatment of people infected with the virus H7N9, which was announced last week , the majority of people who have contracted the disease from another person , it was an accident and can not talk about regularity. However , the danger remains, and the Chinese authorities are doing everything possible to limit the possible outbreak of a real bird flu epidemic.

0 Flu symptoms 2014: H5N1 bird flu death in Canada

In Canada, health officials confirmed the first death from H5N1 bird flu in North America! Deceased woman from Canadian province of Alberta, which has been recently traveled to China.

According to the Minister of Health Canada Rona Ambrose this an isolated case
and there is no danger of the disease spreading, and even less of a bird flu epidemic.

During this flu season in Alberta 10 people have died from swine flu H1N1.

The bird flu H5N1 infects the lower respiratory tract in the lungs and causes
acute viral pneumonia, which in many cases causes the death of the patient.

WHO reported that H5N1 avian influenza is transmitted difficult from person to person , but when people infected with it the mortality rate is about 60%.




Over the last decade in 15 countries around the world were detected 650 cases of avian flu, and 60% of them are fatal.

Only in 2013 reported cases of bird flu were 38 , and 24 of them proved fatal.
Canadian residents have been warned to be especially careful when visiting China, since 60% of cases with fatal outcome.

The virus can lead to a new global bird flu pandemic, the World Health Organization warned in May 2013 in the same year the plague started in China.

Experts say that if the H5N1 virus to mutate and become easily transmissible between humans, the public health consequences could be very serious.

Timothy O'Leary, a spokesman for the WHO, said the organization will not change their risk assessments of H5N1, in view of this development.

He said: "It usually takes 2-8 days for symptoms of H5N1 appear So if someone were infected then we would probably know about it by now..."

"There is reason for concern, but it seems that this is an isolated incident. It was imported from outside North America. 'll Be surprised if there are any cases related to this one from China. 's Hard for people to get it ."

Canadian authorities have followed up with all close contacts of the infected person and offered Tamiflu as a precaution. None of them have bird flu symptoms.

0 Flu symptoms 2014: New Bird Flu Strain, H10N8 kill woman in China!

73 -year-old woman died in China of a new strain of bird flu - virus H10N8, Reuters reported. Case in Nanchang, capital of Jiangxi is single, and the risk that the virus will spread to people is small.

The woman died on 6 December 2013 year as a result of respiratory failure and shock. She sought hospital treatment on November 30 with severe pneumonia. Several days later died of respiratory failure and shock . Prior to infection with the virus, the woman went to the local market for live poultry. People who have been in close contact with the woman , were not detected flu symptoms.

Unnamed experts speculate that this is the single and the risk of spreading the virus and flu epidemic is very small.

Bird flu strain H10N8 has not been detected in humans until now. In August, scientists reported the first case of transmission of viruses like H7N9 from person to person.




People should not panic, because the virus is "fragile and limited", explains the doctor .

In the boom of the avian flu strain H7N9 in China at least 139 people fell ill and 45 of them died. The degree of mortality dramatically decreases from the end of June to now. Cases of H7N9 were found in Hong Kong and Taiwan.

Although China has previously detected H10N8 in wild and domestic birds, this is the first ever report of H10N8 isolated from a patient. Given the potentially unpredictable behaviour of influenza viruses, vigilance and close monitoring is needed.

WHO reports that outside of China, the virus has been found in at least six countries (Italy, USA, Canada, South Korea, Sweden and Japan) in poultry since 1965 year. For people infected with flu virus strain H10N7 was reported from Egypt and Australia. All these patients were admitted with mild clinical signs have fully recovered.

How to prevent of bird flu :

Avoid contact with sick or dead poultry. Keep children away from poultry.
Avoid touching any surfaces that may have been contaminated with poultry feces or blood.
Do not eat raw or undercooked poultry. Cook poultry to internal temperature of 70°C (until meat is not pink in the centre) and do not touch cooked meat with raw meat.
Clean cooking implements that have been in contact with raw meat before re-using.
Wash hands regularly, especially after handling poultry, while cooking and before eating.
Cover your mouth and nose when you cough or sneeze.
WHO does not recommend any specific measures be applied to travellers at this time.
Poultry, poultry products (eggs) and pork can be safely consumed provided they are properly cooked and properly handled during food preparation.

0 Flu symptoms 2013: Chinese bird flu is resistant to drugs

Scientists have discovered a mutation in the new strain of bird flu, showed for the first time in humans in March this year in China, which makes it resistant to key drug without limiting its ability to spread among mammals, Reuters reported, citing published in the journal " Nature Communications ".

The discovery means that unlike seasonal flu strains that often become more difficult transmissible when develop resistance to drugs such as "Tamiflu" to "Roche", the new virus of  bird flu H7N9 has not lost its ability to spread, although developed resistance.





And while it does not strain H7N9 potential to cause a human pandemic, researchers say doctors should be more cautious use of antiviral medications in the treatment of infection with it and be able to use other drugs besides Tamiflu, like Relenza to "GlaxoSmithKline".


"Usually drug resistance damage of viruses, but what surprised us is that in the case of H7N9 resistance does not diminish its ability to spread" says Nicole Bouvier, head of the research team from the hospital "Mount Sinai" in New York.

Experts remind that there is still no evidence of continuing and easy spreading H7N9 strain among people. Published in August scientific analysis, however, offer the most convincing evidence to date that the virus is able to "jump" from person to person and has the potential to cause a human flu pandemic.

In a separate study, experts from the U.S. announced this week that while it is not impossible H7N9 to become easily transmissible from person to person , the virus will have to pass through multiple mutations to achieve it. This means that scientists around the world should continue to monitor it "vigilant" and monitor for signs that developed similar potential .

0 Bird flu H7N9 attacked again, warning of a pandemic!

Syndicate mail alert these days doctors in France for the presence of an alleged case of the deadly bird flu H7N9. The new bird flu strain was detected for the first time in China in late March, and his victims are now 35. Most of them are from the area of ​​Shanghai. Experts are concerned about the speed with which the virus is spreading faster than its mutation and the possibility of infection has to be passed from person to person.

According to the World Health Organization H7N9 is one of the most lethal influenza viruses can stand on the threshold of a new global pandemic. Mankind has no immunity to the new strain of flu in more than 90% of the clinical forms of the disease are severe, and scientists have not been able to invent a vaccine.

Virus spread are increased

One of the most insidious features of the new avian flu strain that infects birds without Symptoms. That is, without making them sick. This complicates the control of the spread of the virus which can survive for several days in the environment. Scientists are still hoping most worrying scenario - the transmission of the new strain from one person to pass us by. The method of transmission of infection to humans, however, lies a mystery.

If birds are the ultimate source of the infection, how do we explain the fact that almost half of those infected before they get sick from avian flu, had no contact with poultry? Such is the case with a patient ill from H7N9 in Taiwan. Virologists studying the cases of infection within a family. To solve the mystery of the new avian flu H7N9, the World Health Organization launched an investigation in China. Peyris Malik, Professor of Virology and Medical Sciences at University of Hong Kong, suggesting that the wide range of deadly virus responsible merchants to help carry the virus between poultry farms and shops.


In 2002, just infected bird cages have been the key factor in the outbreak of the H5N1 strain in Hong Kong, highlights Peyris. It is quite possible that such traffic is one of the major risk factors for the dissemination and the new virus. What is worrying is that last week the dangerous strain was first discovered in a bird purchased on the wholesale market in Dongguan, Guangdong Province, 100 kilometers from Hong Kong. This, according Peyris perhaps the moment when China and Asia need to review practices in poultry-farming, and Hong Kong to serve them as a model of biosecurity. In the first place should be closed wet markets. It is urgent and large-scale testing of blood samples to look for "silent infections." This will help to answer the question can now H7N9 virus of bird flu is transmitted from person to person.

The study will clarify and whether infected develop only mild symptoms - cases they have not hitherto been discovered and reported. If it is proved that the cause of the virus in poultry, getting rid of the deadly H7N9 strain will not be easy because they are very popular food in the world. But experts fear that the new flu strain can now infect other animals, including pigs, make spreading more widely. Because if H7N9 came out of the continent of Asia, can create more problems than his kinsman H5N1, which failed to evolve, but for now over 63 countries, leaving hundreds of thousands of dead birds behind and took hundreds of lives.

Probability of transmission of the new virus of bird flu, H7N9, from person to person, it is much more!

According to experts, the likelihood of transmission of the new virus of bird flu H7N9, from person to person, it is much larger than the other strains, ITAR-TASS reported.
Experts from the World Health Organization in China compared with other H7N9 strains and have concluded that it spreads faster than them. Its susceptibility to mutation greatly increases the risk of illness. The features of the new virus are not fully explored, scientists warn the authorities in Beijing to preserve the condition of caution.
