Epidemiological comments

The reoccurrence of highly pathogenic avian influenza serotype H5N1 is not confirmed and will be closed since the results obtained by the OIE Reference Laboratory in Padova were negative for avian influenza by RT-PCR, virus isolation in embryonated eggs, sequencing, intravenous pathogenicity index test and hemagglutination inhibition test. Further tests were carried out by the same laboratory for Newcastle disease and West Nile fever and they were negative.
Concerning the ravens that died in Abidjan, some people have revealed that they had spread a toxic product, mainly Gambaril; that could be the origin of the deaths reported. Toxicological tests gave negative results.
