One month after Poland's first Newcastle disease infection of 2024 was confirmed, the country reported that two more flocks have been affected by the virus.

The World Organisation for Animal Health (WOAH) reported that both flocks - like the previously affected flock - were in the city of Mońki. WOAH only listed both flocks as "domestic" poultry.

One of the flocks had 24,564 birds, 439 of which died. The remainder of the flock was depopulated.

The other flock involved 35,000 birds. While there were no mortalities among those birds, the flock has been depopulated.

Other control measures applied include zoning, surveillance with7687in the restricted zone, movement control, disinfection, traceability and official destruction of animal products.

The previous flock to be infected in Poland in 2024 involved 51,900 birds.

Until one month ago, Poland had been declared free of Newcastle disease. In 2023, four flocks were affected by Newcastle disease. Those four flocks collectively included 78,315 birds. Following the successful completion of control measures, the situation was declared resolved on November 29, 2023.

Within the past several weeks, one country has had Newcastle disease reappear, while another country was declared free of the disease.

WOAH reported on October 22 that a flock of about 18,000 laying hens in Ödeshög, Sweden, had been affected. Depopulation and other control measures were being put in place at the time the report was issued.

One day after the Swedish case was confirmed, the Newcastle disease situation was declared resolved in Brazil, after control measures were successfully completed in a single outbreak in the country.

The only other country with which WOAH has an active report concerning Newcastle disease is Israel.
