Experts predict that the next is likely to have sporadic cases
Appear in the first half but the possibility of very small-scale epidemic
Added on yesterday Jiaxing case of human infection H7N9 avian influenza, in fact, does not make people feel too surprised.
October 15 Shaoxing new case of human H7N9 avian influenza infection after detecting critical public health emergency, Zhejiang Key Laboratory director of the provincial CDC microbiological laboratory science chief expert Professor Lu Yiyu said, do not rule out another sporadically Zhejiang case situation, but we do not have too much panic. First, compared to other seasonal epidemics of influenza, human infection with H7N9 avian influenza low incidence lot. Second, they are extracted from Shaoxing patients to H7N9 virus were analyzed and found the virus in the first half of this year and more than 99% homology. In other words, H7N9 virus does not mutate, so even if there is sporadic cases, can follow the first half of the treatment and prevention methods used.
Added again in the second half of the province of human infection with H7N9 avian influenza, diagnosis and treatment of human infection of H7N9 avian influenza virus first person, Chinese Academy of Engineering, State Key Laboratory for Diagnosis and Treatment of Infectious Diseases Director Li Lanjuan also said that the second half of people infected with H7N9 epidemic will continue to distribute mainly from person to person is unlikely that the aggregation of the epidemic appears unlikely. And now a vaccine against the H7N9 virus has been developed to complete, ready to be produced, we do not need to panic.
The province of human infection with H7N9 avian influenza expert, an expert personal forecast, the second half of the first half of the epidemic should be no serious epidemic occurred in the first half the size of very small possibility.
Patients infected with H7N9 province
Highest proportion of farmers and retirees, up 70%
At present, Zhejiang has reported cases of human infection with H7N9 avian influenza in 48 cases, including 30 cases in Hangzhou, Huzhou 12 cases, 3 cases of Jiaxing, Wenzhou, Shaoxing two cases and one case.
These 48 patients, the largest proportion of farmers, a total of 19 people, accounting for 39.6%; followed by retirees, a total of 15 cases, accounting for 31.3%; company employees have three cases; other occupations were 7 cases (Cook 1 people, engaged in meat pigeon breeding seller a person, the driver a person, street cadres, a person, a self-employed person, worker 2); unemployed or unemployed four cases.
The age composition, the proportion of patients aged over 60 up to a total of 26 people, accounting for 54.2%; 40 -60 years a total of 13 patients, accounting for 27.1%; 40 patients under the age of 9.
The elderly, patients
Minimize contact with live birds
April 25, the world's leading medical journal "The Lancet" published a research team led by Academician Li Lanjuan writing research papers, thesis titled "" source of human infection with live poultry markets, "the new hair H7N9 subtype avian influenza virus: clinical analysis and viral genome characteristics ", the paper pointed out that human infection with H7N9 live bird market is the main source of the virus have been reported cases, 79% of the patients had history of exposure to poultry; H7N9 virus transmission is mainly through the respiratory tract; more than 60% of patients are relatively poor immunity of elderly patients, so old that get this disease the most important risk factors.
Li Lanjuan academicians believe that the most important thing is prevention of H7N9 we have to raise awareness of influenza. Not cold, pay attention to health care. Strengthening exercises to improve physical fitness. In addition, the contact birds should pay attention to protection, not in favor of the live chickens and ducks to take home. To completely impossible without touching poultry, rural areas where poultry or to a pet. But if there are duck plague fowl plague appeared to timely reporting and timely detection.
As to whether the farmers market to wear masks? The province of human infection with H7N9 avian influenza expert panel is not very recommended because the market of ordinary masks unable to isolate the virus, only a doctor in the isolation ward of N95 masks to block the use of H7N9, but the N95 masks airtight, people will be wearing uncomfortable, not suitable for long wear.
Shaoxing, Jiaxing patients too ill patients than re-
Main is found too late
Work in Shaoxing Liu XX is the first province in the second half confirmed cases of human infection H7N9 avian influenza, aged 35, in a textile company engaged in design work.
October 7, he was vomiting, fever symptoms, a start, let my colleagues to buy him some cold medicine. No effect, but also to the local township hospital treatment, continuous still hung up two days brine temperature 40 ℃ and down. October 11, which is four days after the onset of illness, he was transferred to the First People's Hospital of Shaoxing City, was eventually diagnosed with human H7N9 avian influenza infection.
Zhejiang University School of Medicine Department of Infectious Diseases, First Affiliated Hospital chief physician Joseph Leung, deputy director of Shaoxing in treatment. Liangzhu Ren said, Shaoxing, the patient has made three artificial liver, artificial lung is currently being used, but is still in a state of shock, oxygen saturation is low. To his current physical condition, can not be transferred only in a local hospital's intensive care unit treatment, Zhejiang Province, where people infected with H7N9 bird flu expert team almost every day to the hospital to guide treatment.
Currently looking for a new medical expert effective treatments, including injections to patients trying to have recovered patient's serum, the serum of these patients with a person infected with H7N9 avian influenza virus.
But Zhejiang University First Hospital have been recovered more than thirty cases of human infection with H7N9 bird flu blood test found that only patients with the comfort of a rehabilitation Hangzhou serum antibodies are relatively strong, suitable for the treatment, but the comfort of a patient's blood type and Shaoxing Ryu a blood group incompatibility, can not be paired.
Liangzhu Ren said that, relatively speaking, patients reported yesterday Jiaxing Chen Moumou, although very ill, still in a coma, low blood pressure, but because of earlier detection and diagnosis, so the condition is more stable.
It also reminds us that the early detection, early diagnosis, early treatment is the key to prevention and treatment of H7N9. Once a fever higher than 38 ℃, do not delay, to have fever clinics to immediately above the county hospital.
