Moderator:

The incubation period of avian flu have long? The incubation period will not be transmitted? The route of transmission of avian influenza have what?

Yu Kangzhen:

The incubation period of avian influenza, generally recognized international or a week, but volatility is still relatively large. Some infections, like a few hours, more than a dozen hours or even days will be the incidence. Some can go a long ten days, or even 20 days before onset. The international community in order to facilitate the highly pathogenic avian influenza prevention and control, it provided a longer incubation period, because the back of the protective measures are based on the incubation period to decide. For example, there is no epidemic disinfection after how many days to lift the blockade, are based on the incubation period. Therefore the provisions of the international community are 21 days, after 21 days if there is no outbreak, as evidenced by the elimination of the epidemic was lost.

Again, within the incubation period can be transmitted, we often see it, such as farms, there are several waiting sheds, chicken coop when the beginning of the disease, we will as soon as possible to take urgent measures to kill all the chickens , disinfection and isolation, but after a few days, the incidence of sheds also. However, under normal circumstances or in the incidence of later, with symptoms after detoxification when the highest infection-prone, but do not rule out the incubation period will not be transmitted on.
