Beijing CDC Statement On Imported H7N9 Cases & Advice To Public

FAO Update Feb 15th


Although Beijing has reported two recent imported cases, they are normally somewhat removed from China's yearly H7N9 epidemic, with only 11 cases reported since the virus first appeared in 2013.

This year's epidemic is unusually robust, and two imported cases in less than a week is a bit of a wake up call, which likely explains the rather detailed advice proffered today by Beijing's CDC.

            This year, China appears more H7N9 cases. According to the Beijing Municipal Health and Family Planning Commission Bulletin, February 11, 2017, the Beijing report a case of imported H7N9 cases. The patient is a man in Hebei Province, the local medical institutions for treatment. Because the condition gradually worsened, on February 6 go to the city for treatment. The patient in critical condition, still in the full treatment. After investigation, patients with suspected history of exposure to poultry, which are currently in close contact with no associated symptoms. The patient is the first case of H7N9 cases found in the city in 2017.

            February 14, 2017, the city has reported 2017 second cases of imported H7N9 cases. The seedlings of a patient, male, 48 years old, Liaoning Xingcheng people; the incidence in the local January 31; February 3 - 7 days, patients in local medical institutions for treatment did not improve; February 8 morning, I was transferred to City medical institution.

H7N9 , the disease can not be ignored

            H7N9 as Class B infectious diseases, acute respiratory infections caused by the avian influenza virus, and higher mortality. According to available research data show that as of now its etiological characteristics of the virus, transmission and propagation mode did not change significantly, the birds carry the virus and their droppings, secretions may still be the main source of infection of the H7N9 virus. China city and town live bird markets transactions ubiquitous phenomenon backyard poultry in the short term is difficult to eliminate. Birds carrying the virus situation persists. In view of this, it is expected there will still be cases of H7N9, the epidemic is still mainly sporadic state, there will be a small number of clusters of disease.

            At present, China is in the high season H7N9 epidemic, several provinces in southern H7N9 case report persistent. Although Beijing has issued regulations related to live bird markets closed since 2005, but there are still small-scale illicit trading of live poultry in some urban and rural areas scattered in the sale of live poultry sales and secretly slaughtered condition persists and stored in other provinces live birds enter the case. Therefore, do not rule out the possibility of Beijing residents infected with H7N9 virus. Especially in close contact with poultry workers at greater risk. In addition, Beijing is rich medical resources, a large number of foreign patients to Beijing for treatment, and does not exclude foreign imported cases to Beijing medical institution may be diagnosed.

Curiously, despite today's announcement of another 61 cases from the mainland, and obvious signs of concern both in Hong Kong and Macao, and on the mainland, we are seeing media reports suggesting that China's avian flu outbreak is declining (see Reuters China says bird flu spread slows, vows to stiffen controls).

While one hopes that to be the case, the numbers we've seen announced by the NHFPC over the past couple of weeks (100+ cases) seem about on par with the number of cases we saw announced for the month of January (n=190).
