Is H7N9 very serious and really has nothing to do with dead pigs?

The dead pigs are related to the arrest of those who collected the dead pigs in the previous stage.

Avian influenza is related to the antibiotic injections reported in poultry in the previous stage, hehe.

According to the requirements of the Veterinary Bureau of the Ministry of Agriculture and the Shanghai Municipal Agricultural Commission, the Shanghai Municipal Animal Disease Control and Prevention Center yesterday tested 34 samples of floating dead pigs in the upper reaches of the Huangpu River that were recently salvaged, and no avian influenza virus was found.

According to an investigation by the Shanghai Center for Disease Control and Prevention, the three Shanghai patients, surnamed Li, father and son, basically have no history of contact with live poultry or go out, and are retirees living in the community. Another infected person, 27-year-old Wu, traveled from Jiangsu to a vegetable market in Minhang, Shanghai, in January this year to work as a pork seller. Although poultry is also sold in the vegetable market, Wu did not have direct contact with it, and Wu's stall was at least about 20 meters away from the poultry stall.

According to Wu's family, Wu rarely went to the poultry stall and had contact with poultry. However, the hospital's liver function test of Wu found that Wu had abnormal liver function of Xiao Sanyang.

Last night, the World Health Organization's representative in China, Timothyo'Dr. Leary released information about H7N9 avian influenza in Beijing, saying that WHO would provide all possible help. Previously, it was reported that one of the 27-year-old deceased patients was a pork trader before his death, and Lan Ruiming said in an interview that it could not be ruled out that the source of the disease came from pigs and other animals.

Lan Ruiming said that as far as the WHO knows, there is no correlation between the current three patients, "for their studies and ** are also conducted separately, the laboratory research needs to be very careful, whether the three patients are related, there is no conclusion yet." ”

One of the fatalities in Shanghai was a pork trader who had far more contact with pork than usual. It was also reported that experts who participated in the consultation with Anhui H7N9 avian influenza patients in Nanjing said that the Anhui patient Han had also been exposed to poultry and pigs. When asked whether H7N9 may be related to contact with non-inspection and quarantine dead pigs, Lan Ruiming said that according to past experience, most of the source of the disease comes from birds and birds, but does not rule out the possibility of being related to pigs and other animals.

The case of Shanghai is worth studying, but there is currently no direct evidence to suggest it. Lan Ruiming said that a large number of studies are currently being carried out, including investigating which people and animals the patient has been exposed to, and investigating all possible sources of the disease.

It is reported that up to now, the close contacts with the two confirmed cases in Shanghai have not found similar symptoms and morbidity. Since the beginning of this year, the incidence of influenza and pneumonia in the city has been generally stable, and there has been no significant increase compared with the same period in the past three years. From January 1 to March 31, a total of 24,000 influenza-like cases were reported at influenza surveillance sites in 27 general hospitals in Shanghai, a decrease from the same period in 2012. The surveillance results showed that the incidence of influenza-like cases in the city was at the average level of previous years.

Since January this year, disease control agencies at all levels have not received any reports of seasonal influenza or influenza A (H1N1) outbreaks.

From November 15 last year to March 31 this year, no suspected, clinically diagnosed or confirmed cases of SARS, human avian influenza H5N1 and novel coronavirus were found in the monitoring of 43 influenza surveillance sentinels and 18 national influenza network laboratories in the city, as well as in the active search of pneumonia cases of unknown cause in 130 medical institutions above the second level that opened fever clinics in the city. From January 1 to March 29 this year, the city, district (county) and district (county) centers for disease control and prevention carried out active searches for pneumonia of unknown cause in 130 medical institutions with fever clinics in the city, and the number of patients with fever and lung inflammation decreased compared with the same period in 2012.

It is understood that the H7N9 avian influenza virus infected by humans is the first new subtype of influenza virus discovered in the world, and has not yet been included in China's notifiable infectious disease surveillance and reporting system. When the Shanghai health authorities discovered the above-mentioned cases, they carried out relevant laboratory screening in a timely manner to rule out infectious diseases such as highly pathogenic avian influenza (H5N1) in humans who fell within the scope of surveillance and reporting.

It is also understood that according to the requirements of the Veterinary Bureau of the Ministry of Agriculture and the Municipal Agricultural Commission, the Municipal Animal Disease Control Center today (April 1) conducted a general primer test for avian influenza on 34 samples of floating dead pigs in the upper reaches of the Huangpu River that were recently salvaged, and no avian influenza virus was found.

At present, close contacts of 2 confirmed cases of H7N9 in Shanghai have not found similar symptoms and morbidity.

The city's ** deployment for the prevention and control of H7N9 avian influenza has not detected avian influenza virus in dead pigs in the Huangpu River.

Can avian flu be associated with pigs?

It's far away.,What kind of bird flu are pigs?。。。

As a rule of thumb, pigs do not carry avian influenza viruses!

Avian influenza, the full name of avian avian epidemic, is an animal infectious disease caused by a virus, usually only affecting birds, and rarely infecting pigs. Although the outbreak of avian influenza happened to be the place where the dead pig incident occurred, I personally think that this is a coincidence, after all, it is very rare for pigs to carry avian influenza viruses. But then again, although it is rare, it does not mean that it is impossible, and all claims have to be based on experimental data.

To sum up, I don't think this H7N9 avian flu has much to do with the dead pig incident.

First, the WHO statement does not rule out that the H7N9 avian influenza virus is associated with pigs, and there have been rare cases of pigs being infected with avian influenza.

Second, the official has responded, saying that "due to the limited number of cases, the specific source of infection is not yet known, and it is not clear what kind of animal reservoir it is, and there is currently insufficient evidence to prove that the infection originated from pigs." Yin Ou, deputy director of the Municipal Agricultural Commission, reiterated that the Municipal Animal Disease Control Center conducted a general primer test for avian influenza on 34 samples of floating dead pigs in the upper reaches of the Huangpu River that were recently salvaged, and no avian influenza virus was found. At the same time, Yin Ou said that after a comprehensive investigation in the city, no avian influenza epidemic or pig epidemic has been found, and chicken and pork in the Shanghai market can be eaten with confidence."

We can make an analysis from the above information, if the dead pig incident is related to avian influenza, then first of all, there will naturally be virus in the dead pigs. Further, as mentioned in the above analysis, if the test results are put aside, if the dead pigs carry H7N9, then there will definitely be a group outbreak in the source of the dead pigs along the way, and the current situation is still pointed, and there is no close connection between the individual cases, so the official statement is still credible.

Officially, it claims that it has nothing to do with the dead pig incident.

Generally speaking, avian influenza is transmitted by avian animals, pigs do not carry the virus, and dead pigs are sent to the water and into the sea, and the viability of the virus in the water is not strong, and it does not have the conditions for transmission.

In addition, according to the latest investigation, the deceased and the patient had contact with live chickens or had contact with the patient, so there should be no relationship.

Because a number of ** confirmed that it has nothing to do with this incident. So I'm inclined to be.

Those who have been repeatedly refuted by ** are often worth believing.

You have to understand the principle of virus transmission, which is that two viruses are conjugated and reproduced, and their genetic information is exchanged, and the new disease has the genetic information of two viruses! It's called mutation! H7N9 may be like this, the virus of chickens and poultry is transmitted to the breeder, but generally the virus in chickens and poultry will not be transmitted to humans, because the host is different, can not survive!

It's mutated! It usually takes 2 days for this virus scientist to crack his RNA sequence, and when he does, he will know how he got it! Then you can identify the source of the infection and find out how to crack it!

The former prime minister said: How difficult it is to prosper the country. This means that the more disasters there are, the more prosperous the country will be.

Officials said that it was not the cause of the dead pigs, and the source of the dead pigs had not yet been found in this situation, and it should now appear in migratory birds.

Up to now, a total of 127 confirmed cases of H7N9 have been reported in Nathan Rangrandi across the country, including 26 H7N9 deaths and **26 deaths.

At present, H7N9 cases are distributed in 39 city-level areas in 10 provinces and cities, including Beijing (1 case), Shanghai (33 cases, 13 deaths), Jiangsu (27 cases, 6 deaths), Zhejiang (46 cases, 6 deaths), Anhui (4 cases, 1 death), Fujian (3 cases), Jiangxi (5 cases), Shandong (2 cases), Henan (4 cases), and Hunan (2 cases). The case is sporadic and there is no evidence of human-to-human transmission.

As of 19:00 on April 27, a total of 121 confirmed cases of H7N9 avian influenza were confirmed across the country, including 23 deaths, and the cases were divided into Beijing (1 case), Shanghai (33 cases, 12 deaths), Jiangsu (27 cases, 4 deaths), Zhejiang (45 cases, 6 deaths), Anhui (4 cases, 1 death), Henan (4 cases), Shandong (1 case), Jiangxi (2 cases), Hunan (2 cases), Fujian (1 case), and Taiwan (1 case).
