The World Organisation for Animal Health (WOAH) has confirmed that a fresh case of the highly pathogenic H5N1 bird flu has been reported in the northwestern part of Senegal.
In a report citing Senegalese authorities, the Paris-based WOAH said an H5N1 outbreak occurred two weeks ago at a farm in Potou near the town of Louga.
“It is highly likely that there is an epidemiological link between both outbreaks,” the body said.
WOAH said the outbreak killed 500 birds in the 11,400-strong flock, with the remaining animals culled.
Over 200 million birds have been killed by avian influenza, commonly known as bird flu, in the past year, sending egg prices skyrocketing and raising fears about human transmission.
Earlier this year, three African countries reported avian flu cases in poultry. In West Africa, new outbreaks of the flu were reported on farms in Niger and Nigeria. Two different virus variants have been linked to the latest outbreaks in South African poultry.
Avian influenza refers to the disease caused by infection with avian (bird) influenza (flu) Type A viruses. Three subtypes of avian influenza A viruses are known to infect people (H5, H7, and H9 viruses).
The flu is a major concern for public health. According to WHOAH, where outbreaks occur, it is best to cull all poultry, whether infected or healthy, to contain the spread.
