To curb the disease's spread, many countries have implemented measures like active surveillance to detect cases before it can further impact bird populations. More in the latest OFFLU report:

On 5th December 2022, OFFLU held an online discussion with experts of all regions representing many countries to share information on avian influenza situation in poultry and wild birds since 1st October 2022.
The goal of this meeting was to get an improved understanding of the current situation and share initial findings and experiences on the most recent wave of outbreaks in poultry and wild birds in different countries.
Participants:
Ian Brown (UK); Alice Fusaro (Italy); Timm Harder (Germany); Eric Niqueux, Beatrice Grasland (France); David Swayne, David Suarez, David Stallknecht, Jonathan Sleeman, Andy Ramey, Julianna Lenoch (USA); Yohannes Berhane (Canada); Dilmara Reischak (Brazil); Abdelsatar Arafa (Egypt); Celia Abolnik, Lia Rotherham (South Africa); Samantha Letsholo (Botswana); Clement Meseko (Nigeria); Hualan Chen, Yanbing Li, Jiming Chen (China); Viktor Irza (Russia); Yoshi Sakoda (Japan); Chakradhar Tosh (India); Youn-Jeong Lee and other experts (Rep. Korea), Andrew Breed, Les Sims (Australia); Ron Fouchier (Netherlands); Sasan Fereidouni, Pastor Alfonso (Cuba), Nestor Alfonso, Experts from Colombia; Lidewij Wiersma, Amelia Coggon, Akiko Kamata(FAO); Aspen Hammond and WHO GIP colleagues; Keith Hamilton, Gounalan Pavade (WOAH).
Japan:
This season to date there is already more outbreaks noticed compared to last winter in poultry. There are many outbreaks in chickens and a small number in ducks. The number of outbreaks detected in wild birds is unprecedented. Noted a change in wild bird species compared to last year – last year it was crows and this year cranes were affected (in addition to water birds both years). Incursions are caused by the same viruses which Europe and North America were experiencing in 2021-2022 which gives evidence for re-incursion due to migrating birds. The viruses currently causing disease are slightly different to what is found in European countries.
India:
There is active and passive surveillance in poultry and wild birds. Active surveillance is detecting predominantly H9N2 in chickens, ducks and wild birds and passive surveillance is detecting H5N1 virus in domestic ducks, chickens and wild birds. In the southern part of India there were outbreaks in ducks with clinical signs being seen including corneal opacity and torticollis. The cleavage site of these viruses was confirmed as being highly pathogenic in chickens. Increased mortality was noted in backyard chickens, and H5N1 virus was confirmed. Gross pathology included congestion, oedema and haemorrhages in lungs. A wild dead bird (Pond heron) was confirmed with H5N1 virus infection.
Rep. of Korea:
There is a nationwide active surveillance program, particularly since the first detection of HPAI in wild birds this season. Broiler chickens are tested before movement to slaughter houses, broiler ducks are tested multiple times before movement to slaughter houses and other poultry farms are tested on a biweekly basis. ...
