Shandong infected with H7N9 & Sons symptoms gap significantly difficult to support human-to-human transmission

China news agency, Ji'nan, April 29 - The Shandong Zaozhuang father and son have confirmed human infection with the H7N9 avian influenza, at present, only from the point of view of clinical symptoms, father and son performance differences are significant. Avian flu "human-to-human transmission," saying there is no clear evidence to support. "the provincial medical treatment team leader, Shandong Provincial Chest Hospital Dean Professor Gao Taichuan 29, 2009, said in an interview with China news agency reporters.
Tall Chuan said, "I Zaozhuang Municipal Hospital of these cases of H7N9 avian influenza cases Sons consultation just returned to Jinan children are pediatric infections emergency room for treatment, children with the disease situation is relatively stable, normal eating and sleeping, showing the local symptoms of pneumonia, but her condition is not severe but not critical condition. based on clinical diagnosis, the children viruses and bacteria combined infection, white blood cell count is high. development of the children's condition is relatively stable, according to the incidence of early and contrast six hours after the diagnosis, the development of the children's condition and did not show the rapid deterioration of the situation. "
The progression of the disease but the children's father is unstable, on admission, no obvious pathological symptoms, but the hospital after 4 hours, the rapid development of the disease, the rate of deterioration soon. "Tall Chuan said the children's father after 7 days after emergency treatment, although not completely out of danger, but relatively stable vital signs, do not need the support of ECMO (artificial heart-lung machine).
Tall Chuan, because the presence of a history of close contact, not directly related to exclude possible, but only from the point of view of symptoms, the gap between the two is obvious. The same time, on a time basis, the degree of association of the symptoms of the father and son do not have the "human-to-human transmission performance. H7N9 avian influenza longest incubation period of seven days, the children in father hospitalized for 8 days, was found to have a fever, children diagnosed with the H7N9 avian influenza patients time the past 10 days. This case, the emergence of the cases of familial aggregation, does not mean that the virus H7N9 has mutated into a human influenza virus continued to spread from person to person. Currently, the state health department epidemiological investigation and laboratory tracking of all cases, it is still the main mode of transmission of infection from birds to people.
