Bird flu in China: As the Chinese authorities struggle to contain the spread of Avian Influenza, the world body said it has approved the establishment of a national command center. Vice Premier Hui Liangyu has been appointed to direct the center. China has been actively collecting samples from suspected outbreak sites in an effort to fight the virus. The WHO said that Chinese labs have begun testing the virus in humans and poultry. Meanwhile, the WHO says it will send samples from outbreak sites to its laboratory in Shanghai for further study.

China reported H10N3 Bird Flu First Case
In the past month, a new strain of avian influenza has emerged in China. This strain is among the “most lethal” strains because it can easily jump from birds to humans. While it is unlikely to cause a global pandemic, scientists say there is little evidence that the virus can survive in humans. However, if this new virus is able to spread from human to human, it could cause a global pandemic.
This strain was previously known to only infect birds, but the recent Chinese outbreaks suggest that this virus may have the potential to cause a worldwide pandemic. The virus’ genes appear to have adapted to grow in mammals, making it more easily transmissible. Scientists have analyzed avian flu viruses’ genomes to predict where they might end up next.
The virus’s source has been traced to open poultry markets. Scientists are concerned that this new strain could spread from birds to humans, and therefore have begun to trace its spread to poultry markets in China. But the WHO says it is too early to say if the virus is transmitting from one species to another. This new virus also jumps from poultry to humans and can be transmitted from one species to another without any obvious symptoms. Because it can jump from bird to human, it’s harder to track its spread.
In Suzhou, a 53-year-old man has tested positive for avian flu. He had recently traveled to mainland China and returned via Shanghai. He has been in critical condition at a local hospital since April 16. The outbreak has spread across the country and has already caused 22 deaths. It is the result of H5N6 being the most widespread strain in China.
Bird Flu affects birds
In a recent study of waterbird populations in Guangdong Province, researchers found that the length of roads, area of construction land, and number of aquaculture ponds were all associated with lower numbers of birds. The study also found that waterbird populations were affected by the presence of mangroves. The disease can also affect birds that rely on open water for food and shelter, so officials are trying to prevent it.
Although the H5N6 strain is generally specific to birds, the virus can infect humans. Luckily, this strain hasn’t proven to be deadly for humans, so the risk of a pandemic is low. Nevertheless, the Chinese health commission has instructed officials in Henan Province to implement prevention programs. According to the U.S. Centers for Disease Control and Prevention, there are 33 million cases of avian influenza A in the U.S. this year.
Over the last few decades, China has armored its coastline by building sea walls and turning more than half of its coastal wetlands into solid ground. The development has affected migratory birds’ food and habitat. Because coastal wetlands are vital to the migration of birds, 10% of the species on this flyway are in jeopardy of extinction. One of the most endangered species, the spoon-billed sandpiper, is in particular danger of extinction, with only 200 breeding pairs remaining in the wild. Reclaimed land is one of the biggest threats to the mudflats.
Aside from the loss of habitat, the country has a diverse climate and a high degree of endemism. As of this year, 1372 species of birds are present in China, including 77 strictly endemic. Of those, 29 of them are threatened or critically endangered. The Chinese government supports the Red List of Vertebrates (Bird) in China, which evaluates the status of endangered and threatened species. Throughout the study, 27 researchers assessed the status of bird populations in China.
Spreads through respiratory droplets
Humans exhale fluids, called respiratory droplets, that carry viruses, bacteria, and other microorganisms. These droplets can be inhaled by other humans, and they can also spread infection when they come into contact with inanimate objects. The risk of transmission is greatest when people are near the source of the infection and the concentration of droplets and particles is high. Also, the risk of transmission is increased if infected people touch surfaces that are covered with mucous membranes, such as a coughing hand.
Although respiratory virus transmission methods are similar to those of other diseases, it is not always clear how they are transmitted. Traditionally, transmission occurs through direct physical contact, but some researchers consider exposure to infectious droplets an additional mode of transmission. Because there is no consensus on the exact definition of contact, ‘droplet contact’ may refer to the transmission of infectious droplets rather than direct physical contact. However, researchers are continuing to debate the exact definition of respiratory virus transmission.
New studies are beginning to confirm the theory that a novel coronavirus can be transmitted through respiratory droplets. This hypothesis has been challenged by more than 200 scientists who wrote an open letter to the World Health Organization that noted cumulative evidence that the new coronavirus is spread through aerosols. The revised text contains new information on respiratory droplet transmission through talking and choir practice in Washington State. There are some other factors that may contribute to the transmission of the new coronavirus, but researchers are not convinced that any of them are responsible for a new case.
The viral particles in respiratory droplets are released into the air, where they remain for a few hours. The respiratory droplets themselves can be highly infectious, so it is best to avoid physical contact with infected people when possible. The particles are highly infectious and can be transmitted by kissing, hugging, or high-fives. People should also wash their hands after coughing, sneezing, or contacting infected surfaces.
Bird Flu affecting humans
Chinese health officials have confirmed the first human case of the H3N8 strain of bird flu. The case is of a four-year-old boy who came into close contact with wild ducks and chickens. The man was admitted to the hospital on April 28, and has recovered. The risk of the bird flu spreading to humans is very low. The man contracted the virus accidentally through close contact with infected birds, and there are no confirmed cases in other close contacts.
The H5N1 strain of bird flu leaves a trail of dead poultry. But the H7N9 strain infects birds silently and spreads through flocks undetected. The virus can jump from birds to humans at poultry markets. The CDC reports that as of mid-April, 63 cases had been reported. The H7N9 virus has mutated after jumping from birds to humans. Humans are more susceptible to the H7N9 strain than the H5N1 strain did.
In 2009, the CDC confirmed that the virus that caused the China outbreak was made up of three strains. One of these strains was derived from pigs, and the third was from humans. Scientists have speculated that the human strain could be just a few mutations away from becoming contagious. Scientists are urging people to stay away from China until more information is released. In the meantime, the Chinese government is preparing for the worst by restricting trade in pigs.
The virus is causing death in migratory birds in western Siberia, Tibet, and Mongolia. It has already spread to turkey, mute swans in Croatia, and poultry in Hungary, and has reached Jordan. It has also been linked to the first human cases of the virus in China. The CDC estimates that there are 33 million cases of the disease in the United States. And this is just the beginning.
Bird flu could evolve into a pathogenic strain
The first human cases of H5N1 were reported in 1997. A mass slaughter of 1.5 million chickens contained the outbreak. Since then, human cases have been reported in Europe and North Africa. In addition to Asia, humans are now also becoming infected with the virus. The virus has been found in dead birds from several countries where there have been no reported human cases.
Although China has many different strains of the virus, H10N3 has been the first human case of H10N3. While some strains of the virus are not pathogenic and infect only poultry, it is a concern because it could evolve into an invasive form of the disease. Although the virus does not infect humans easily, the man’s case was the first reported human case. The health commission did not give details on how the man contracted the virus.
Because of its ability to infect humans, H5N1 is still a major concern for public health. It can be transmitted from poultry to people through home slaughter or plucking infected birds. However, the potential for the virus to evolve into a pathogenic strain is the primary concern. The virus can combine with other influenza viruses and spread throughout the world and cause a pandemic.
The HPAI outbreak has spread to more than 48 million birds in seven months. The US Department of Agriculture reports that the virus has already affected 48 million birds. The outbreak has spread to other countries in Africa, Egypt, and the US. The latest outbreak has reached the Middle East, where it has been detected in wild birds. The virus was first reported in Egypt in May 2006 and is now being detected in the Middle East.
