    Abstract

    Serological surveillance conducted in H7N9 outbreak areas of China found no sero-positivity for antibodies specific for avian-origin H7N9 virus among 1129 individuals of the general population, whereas greater than 6% among 396 poultry workers were positive (HI titers ≥80), confirming that infected poultry is the principal source of human infections and subclinical infections are possible. Elevated antibodies to the H7N9 virus were found in 65.8% (25/38) of survival cases but only in 28.6% (2/7) of fatal cases after an interval of 10-14 days, suggesting the presence of antibodies may improve clinical outcome in infected patients.
