Abstract: surveillance purposes.However, because of the small number of infl uenza virus (H5N1) case-patients, our study was too underpowered to draw any fi rm conclusions; results should be interpreted cautiously.In a study of cases in Vietnam, 5 case-patients did not have any identifi ed exposure <7 days of illness onset (10).In China, the exposure period for surveillance of suspected cases now includes exposure to a wet poultry market <14 days before illness onset.Although data on person-to-person virus transmission are limited, close contacts of patients infected with infl uenza virus (H5N1) in China are monitored daily for 10 days after the last known exposure.Further studies are needed to quantify the incubation period after exposure to sick or dead infected poultry, a wet poultry market, or to an infl uenza A virus (H5N1) case-patient and to investigate the basis for any differences.
