Abstract

Between 16 February and 15 May 2018

,

three

highly

pathogenic avian influenza (HPAI)

A(H5N6) and

11 HPAI A(H5N8)

outbreaks in poultry holdings

,

one HPAI A(H5N6) and one HPAI A(H5N8)

outbreak

in captive birds,

and

55

HPAI A(H5N6)

wild bird events

were reported in Europe

.

T

here is no evidence

to date that HP

AI A(H5N6) viruses circulating in Europe are associated with clades infecting humans.

F

ewer HPAI wild bird cases have been detected

than during the same period of previous year

.

Most

of

mortality events

among

wild bird

s

involved single birds

and species li

sted in the revised list of target

species for passive surveillance. Raptor species constitute 7

4

% of the HPAI

–

infected wild birds found

dead. Those raptor species

probably

bec

a

me infected by hunting or scavenging HPAI

virus

–

positive

birds, and so raptor c

ases may predominate later in the course of an HPAI epidemic. Despite the

important

HPAI virus

incursion via wild birds there have been few associated HPAI A(H5N6) outbreaks

in poultry.

Fifteen

low pathogenic avian influenza (LPAI) outbreaks were reported

in three Member

States. The risk of zoonotic transmission to the general public in Europe is considered to be very low.

T

he situation in Africa

and the Middle East

should be closely monitored

with regards to HPAI A(H5N1)

and A(H5N8)

.

Uncontrolled spread of

the

virus and subsequent further genetic evolution in regions

geographically connected to Europe may increase uncertainty and

the

risk for further dissemination of

virus

.

Long

–

distance migrating wild birds from

s

outhern Africa, e.g.

the

c

ommon tern (

Sterna

hirundo

), may be included in targeted active surveillance schemes at a few priority locations in Europe

in order to detect HPAI A(H5)

–

infected migrating birds

early

.

However,

t

he risk of HPAI introduction

from

non

–

EU

countries via m

igratory wild birds to Europe is still considered

to be

much lower for wild

birds crossing the southern borders

than for those

crossing the north

–

eastern borders.
