First detection in 2016 of Highly pathogenic H7N8 Avian Influenza (HPAI) has been confirmed by the United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS). The outbreak appeared the 16th January, 2016 in a commercial turkey flock in Dubois County, Indiana. In 2015, USA experienced a number of influenza outbreaks (232 outbreaks in 15 states, last outbreak was detected June 17) and Indiana reported one outbreak in a backyard flock affecting 76 birds.

The strain involved in this outbreak is different from the strains involved in 2015 outbreak. Further investigations tend to show that this highly pathogenic strain mutated from a low pathogenic one.

There are no known cases of H7N8 infections in humans.

A case of Rabies in a 6-month puppy living in Cayenne (French Guiana) has been diagnosed by Pasteur Institute (Paris).

The dog was hospitalized at a veterinary clinic for nervous symptoms (convulsions, aggressiveness, visual loss and difficulties with movement) and died.

The virus isolated is a Lyssavirus, of Rabies virus (RABV) species and of bat rabies type. An epidemiological investigation is ongoing to identify all contacts with humans and other animals. A regulated zone has been established to strengthen surveillance.

Origin of contamination has not been determined but is likely linked to contact with bats.

Rabies hasn't been diagnosed in domestic animals since 2003 (a dog in Cayenne) and in wildlife (bat) since 2009, when the rabies virus was first isolated in a bat in French Guiana. The last human case was reported in 2008. Since 2008, a ministerial decree has made vaccination against rabies mandatory for all domestic carnivores and herbivores in French Guiana.

Rabies of bat type is endemic in French Guiana, and French Guiana is free from canine Rabies, however the risk of introduction is not negligible considering the Rabies situation in the Caribbean and the illegal imports of pets.

Center for Disease Control (Atlanta, USA) reported a human infection with a variant Influenza A virus of pig origin, i.e. an Influenza virus normally circulates in swine and not people.

Since 2005, 354 cases of H3N2v have been reported in the US and other variant influenza (H1N1v) have also been reported. Most of the human infections result from exposition to infected pigs and some cases of limited person-to-person spred have occured.

Human to human transmissions are closely monitored especially for variant Influenza A as pigs are known to be mixing vessels that may lead to more virulent strains for humans.

Belmopan, Belize:

No new premises positive for Avian Influenza Low Pathogenic H5N2 have been detected since 5 june 2015, when one layer flock situated in a hot spot of a declared infected area tested positive.

The Avian Influenza event in belize with three outbreaks has resulted in a total of 26 infected poultry flocks that included breeders, layers, broilers and hobby birds. Stamping out measures resulted in a total of more than 80,000 birds destroyed, disposal by burial and decontamination of all infected premises. All infected flocks have been within a 5 km radius from the index case, located in Spanish Lookout (Cayo District) - a major poultry production area in Belize. The virus was first detected after routine testing, under the Avian Influenza Programme of the Belize Poultry Improvement Plan.

The virus ins an American Chicken Avian Influenza low pathogenic virus. It showed 98,8% similarity with a strain isolated in Mexico in 2012. No clinical signs have been associated with the disease in Belize.

A 3-month enhanced surveillance following OIE guidelines is in place post the cleaning and disinfection of the last known positive farm in order to regain LPAI free status in domestic poultry.

Since notification of low pathogenic H5N2 by Belize Agricultural Health Authority (BAHA) in January this year, Belize has submitted to the OIE several follow-up reports. Access all reports here:

- Immediate notification

- OIE follow-up reports: N°1 (23 Jan.), N2 (10 Feb.), N°3 (17 July), N°4 (14 Aug)
