Turn of the year H5N6 caused one death and one serious injury provincial disease control: No variation to human transmission of the virus
Winter and spring high incidence of bird flu, H7N9 has slowed down, H5N6 again, "trouble" - beginning of the end of December 29, 2015, January 1, 2016, Shenzhen, Zhaoqing found two cases of H5N6 infections, causing one death and one ill. At present, six cases of H5N6 cases worldwide found three cases in Guangdong.
Yesterday afternoon, the provincial CDC chief expert, mass anti Jianfeng, director informed the media, the two cases are the property of sporadic sporadic H5N6 virus, the virus mutates to a human successor was not found, the key to preventing infection in reducing close contact with live poultry.
Text / Guangzhou Daily Reporter Reporter He Xuehua correspondent Guangdong Health Letter
Last December 29, the Shenzhen Municipal report one case of H5N6 cases, patients Wu, female, 26 years old, live Bao'an District of Shenzhen City. December 24 Wu disease, but did not seek immediate medical attention, December 29 to see a doctor and be diagnosed H5N6 virus infection, admitted to Shenzhen designated hospital has now been critically ill in hospital, on December 30 died.
January 1 this year, Zhaoqing report one case of H5N6 cases, patients Hemou, female, 40 years old, living for Zhaoqing City. Hemou after onset, the primary hospital for two days, after severe illness turn go Zhaoqing City People's Hospital intensive care unit, the current condition is still heavy. Disturbing that Hemou also a maternal infection after H5N6 Caesarean section.
Virus "ferocious"
Two days in patients' lungs all white. "
It was once dreaded H7N9, mortality was 40%; In contrast, H5N6 more "evil." According to statistics, currently the world were found and confirmed six cases of H5N6 virus infection, all in China, including one case in Sichuan, Yunnan two cases, three cases in Guangdong.
Guangdong early detection of cases at 15 December 2014, the Guangzhou CDC first detected the H5N6, confirmed that 58-year-old man in Guangzhou Panyu a hill, is the world's first case of human infection with the H5N6 influenza cases survived, and then transferred to Canton Medical Institute hospital with severe respiratory medicine, through the full treatment a month cured.
According to doctors in Guangdong for three clinical description of H5N6 cases, since the detection of severe pneumonia, found that patients had lung shadows, they begin to turn white within the lungs is only one day, the next day, "all white lung", Shenzhen onset cases December 24, December 30 death, also seven days time, progress in three cases of severe pneumonia very quickly, even faster than H7N9.
Common feature
We have a history of exposure to live poultry market
And ask the virus come from, can be found in three patients have contact with live birds or live poultry market exposure history.
Qiu first patient in a long-term smoking and colon cancer surgery done, time to market to buy chicken meat to eat on the way home to the rain, began the incidence of infection process. Shenzhen Wu second patient, go to the market to buy a home to ducks. From the perspective of bioinformatics confirmed that Wu cases are due to contact with live poultry or external market environment infection. Third patients Hemou Zhaoqing, also went before the onset of the sale of live poultry markets. Disease control department detected the H5 virus from the associated environmental samples.
Do not panic too
Sporadic cases and not human to human transmission
Continuous two people infected with H5N6 virus, does that mean H5N6 bird flu virus has to infect people across racial barriers?
In this regard, Jianfeng said: "The description of H5N6 among birds has become an advantage of influenza virus strains and the virus mutates occasionally infected people." However, the public need not panic too much, molecular biology currently found in Guangdong H5N6 also is typical of Avian influenza virus, the key non-variant gene locus to obtain the ability to continue to infect humans, "but it does infect a person, worthy of attention."
In addition, Guangdong three confirmed cases, H5N6 occasionally infected people, there is variation pleasant human transmission has not occurred.
A first patient mound, all close contacts no exception; and second close contact with patients Wu crowd, no disease; third patient 64 close contacts and market poultry five employees, so far no abnormalities .
Prevention key
Reduce close contact with live poultry
Guangdong expert group's analysis: 1 to 2 months, the spread of avian influenza virus in human lower risk, but does not rule out the possibility H5N6, H7N9 and other sporadic cases arise. So, individuals how to effectively prevent H5N6 infection? Jianfeng that the reduction in close contact with live poultry is the most critical.
He pointed out that Guangdong found multiple cases, does not mean "Guangdong's most dangerous", but explain unexplained severe pneumonia in Guangdong monitor effective, virus traceability clear, case tracking in place, Guangdong has a stronger ability to find cases.
Of course, on the other hand, also with the Guangdong live poultry sales patterns. Cantonese shopping, love and live poultry and other animals close contact, and trafficking together market geese, ducks, chickens, fish and other waterfowl, the market has become mixed with a stirrer, to the virus mutating, restructuring provides an opportunity. Most people are not easy to move, but the move does not rule out sporadic cases of human infection.
Therefore, Jianfeng repeatedly called for change to buy live poultry slaughtering their own habits, focus on live poultry slaughtering, cold chain distribution, fresh listing is good to reduce human exposure to infection with the virus pattern.
Treatment is expected to
Neuraminidase inhibitor effective
Guangdong three cases H5N6,1 were cured, one case being seriously ill, one case has died, whether the clinical treatment of H5N6 have explored a trick?
In January 2015, led the call Guangzhou Institute team, Guangdong the first case of H5N6 critically ill patients successfully cured respiratory disease expert Zhong Nanshan pointed out famous, confirmed the first case of treatment, H5N6 virus as long as the early use of oseltamivir and other neuraminidase inhibition anti-viral agents, patients can cure incorrigible.
Jianfeng yesterday, citing the recent two cases further treatment of the case, said, when clinical findings in patients with influenza-like illness, fever, sore throat, muscle aches, fatigue, combined with live bird markets or history of exposure to live poultry practitioners involved in the crowd, it is recommended as soon as possible (most Well within 48 hours) with neuraminidase inhibitors, treatment success depends on early treatment.
Jianfeng reminded, there is underlying disease of the elderly, low immunity, pregnant women and other people, once infected with H5N6 virus, likely to develop into severe, it is recommended to go to the market as little as possible.
Prevention and control of bird flu three to three not
To wash hands: After contact with poultry, wash hands before meals and after.
To cook: poultry and eggs should be cooked before eating.
To early treatment: If fever, cough, headache, general malaise and other respiratory symptoms, we should as soon as possible to the nearest medical institution for treatment. Before contact with birds, to take the initiative to tell the doctor.
Do not eat dead poultry.
Do not buy from unknown sources poultry products.
Do accommodation in live poultry stalls.
