"WE HAVE TAKEN THE OPTION OF CONTAIN AND NOT THAT OF VACCINATION"

Dr Amadou Gu?ye, specialist in public health, no less coordinator of the technical committee of the poultry industry in Senegal confirms avian influenza in Senegal

Jean Pierre MALOU | Publication 16/01/2021

Avian flu has been announced in Senegal since December 23 of last year. Immediately after the veterinary services took the issue head-on. This is confirmed by Amadou Gu?ye, specialist in public health, no less coordinator of the technical committee of the poultry industry in Senegal.

“Conservative measures have been taken by blocking all products until after treatment. What was done. After analysis, the disease turned out. And everything has been locked so that the disease does not migrate, ”said Mr. Gu?ye. And to continue, "Since this avian flu appeared in a poultry farm in Pout (Thi?s), precautionary measures (stamping out) have been taken to stop the disease outright". “Up to this day (yesterday), it is a single outbreak of 100 thousand poultry, located in the forest of Pout (Thi?s). And all these poultry were slaughtered with the authorization of the administrative authorities, in this case the prefect ”.

Of course, he will say: "It is a consequent economic loss but it is a single poultry farm which is an epidemiological unit". In other words, it is "a single home", he wishes to clarify. To slaughter all these poultry, he will say: "The prefect has set in motion the police, the gendarmerie, a company with mechanical shovels for deep burial to prevent contamination". However, in relation to the slaughter, he specifies: “In Senegal, the health police law has drawn up a list of diseases deemed contagious. And for each of these diseases, when it appears somewhere, the state orders the stamping out. And it is on this basis that the breeder is compensated through the official services, in agreement with the operator ”.

When asked how this avian influenza appeared in Senegal, the poultry expert confided: "We are required to understand, but only the investigation will tell us". But, he will add: "I admit that it is a disease that we know even if we do not have it in Senegal but it can go through the wind, migratory birds, animate or inanimate vectors. ". Regarding the strategy adopted or to be adopted, Doctor Gu?ye said: “For the moment, we do not think we have to vaccinate because we have taken the option of confining the disease. In other words, kill in the bud and that's why we did the stamping out ”.

However, he said: "If the situation were to necessitate vaccination, we will not hesitate to do so by placing the order which is available ...". Finally, he will say: "Currently the henhouse has been completely disinfected, closed for a month and the crawl space is under observation before giving the owner the discharge so that he can resume his activities".

Environment. Massacre in Senegal: 750 pelicans found dead

10 mins ago

ngadmin

The Senegalese authorities announced on Wednesday the “suspension” of public access to the Djoudj ornithological park after the death of at least 750 pelicans, a massacre unrelated to a recent outbreak of bird flu, according to the first elements of the report. .:magnify:

“This January 23, following a patrol, a high mortality was noted: 750 pelicans (740 youngsters and ten adults),” the Ministry of the Environment said in a statement.

....There are almost 400 species of birds, or more than three million individuals.
Destroyed corpses

....
Pelican carcasses and waste have been destroyed and public access and canoe trips in the park backwater have been suspended.

The authorities have already ruled out the hypothesis of bird flu, from which a recent outbreak in a poultry farm in the west of the country was officially circumscribed, as the cause of this unusual mortality of Djoudj pelicans.

“Bird flu only affects grain-eating birds. Pelicans eat fish. We cannot say that it is this disease,” said the national director of national parks, Bocar Thiam..:tiphat:https://www.ngwinnett.com/2021/01/27/environment-massacre-in-senegal-750-pelicans-found-dead/

DAKAR (Reuters) - Some 750 pelicans found dead in a UNESCO World Heritage site in northern Senegal last week have tested positive for H5N1 bird flu, the head of the parks authority told Reuters on Friday.

Rangers found the pelicans on Jan. 23 in the Djoudj bird sanctuary, a remote pocket of wetland near the border with Mauritania and a resting place for birds that cross the Sahara Desert into West Africa each year.
