A positive reaction for type A avian influenza virus was confirmed. When the above five Jungle Crows were genetically tested at Hokkaido University, it was reported that highly pathogenic avian influenza virus (H5N1 subtype and H5 subtype) was detected on Thursday, April 7. In addition, one debilitated tanuki, which was recovered on April 1 (Friday) near the recovery of the above-mentioned Jungle Crow and independently inspected by Hokkaido University, is highly pathogenic on April 7 (Thursday).

In addition, a highly pathogenic avian influenza virus was collected on April 4 (Monday) for one red fox that was collected by Hokkaido University on March 31 (Thursday) near the above-mentioned Jungle Crow and independently inspected. There was a report that (H5 subtype) was detected.

1. 1. background

Jungle Crow

March 29 (Tuesday)	・ Collected 7 dead individuals of Jungle Crow in Sapporo, Hokkaido ・ A simple test of 5 birds confirmed a positive reaction of type A avian influenza virus from all 5 birds. ・ Strengthen wild bird monitoring by designating the area within 10km around the collection point as a priority area for wild bird monitoring.

Fox

March 31 (Thursday)	・ Hokkaido University collects one dead red fox in Sapporo, Hokkaido
April 4th (Monday)	・Highly pathogenic avian influenza virus (H5 subtype) was detected as a result of conducting a genetic test in an original test conducted by Hokkaido University.

2. 2. Future response

• In coordination with Hokkaido, an urgent survey (birds) aimed at understanding the status of virus infection in wild birds within the priority area for wild bird monitoring, estimating the source of infection, and obtaining basic information to prevent further spread of infection. We are planning to carry out investigations, investigations of dead wild birds, strengthening of abnormal monitoring of wild birds and beasts, etc.).
• The nationwide response level in wild bird surveillance has been raised to the highest level of "response level 3" as of November 11, 1991, and we will continue to strengthen monitoring of wild birds nationwide.

3. 3. Points to note

(1) Avian influenza virus is not considered to infect humans unless there is close contact with infected birds. In daily life, if you wash your hands and gargle after touching the excrement of birds, you do not have to worry excessively, so behave calmly not only in the surrounding area but also in the people. I would like.

(2) Although several cases of fox infection have been confirmed overseas, it has been suggested that the infection may have been caused by predation of birds infected with highly pathogenic avian influenza, and infection between foxes has been confirmed. not. In addition, it is unlikely that it will infect humans in daily life.


(3) If many wild birds die in the same place, please contact the nearest prefecture or municipal office.
