Avian Influenza Outbreaks 2023
Avian Influenza Outbreaks 2023
Avian influenza (Bird Flu) is a disease caused by influenza type A viruses that occur naturally among birds and domestic poultry. Highly pathogenic avian influenza (HAPI) A virus subtypes (H5, H7, H9) A(H5N1) first emerged in southern China in 1997.
According to the FluView dashboard, 54 countries reported an H5N1 outbreak in birds to the World Health Organization (WHO) in 2021, 2022, and 2023. In the WHO for Animal Health Monthly Situation Report on January 5, 2023, there were 290 highly pathogenic avian flu outbreaks in poultry and 140 events involving wild birds, outpacing activity in 2022.
In addition, the United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) stated the Eurasian H5N1 strain appeared in North America in January 2022, affecting 47 states, leading to the loss of over 57.8 million birds as of January 17, 2023.
Avian Influenza (Bird Flu) in Humans
Zoonotic influenza infections in humans may be asymptomatic or may cause disease, from conjunctivitis or mild, flu-like symptoms to severe, acute respiratory disease or even death, depending on factors related to the virus-causing infection and the infected host, says the WHO.
The U.S. CDC confirmed in 2023 that although bird flu viruses mainly infect and spread among wild migratory water birds and domestic poultry. Human cases of infection with avian influenza viruses are usually the result of direct or indirect exposure to infected live or dead poultry or contaminated environments. As on November 2022, the CDC tracked the health of more than 5,190 people with exposures to HAPI-infected birds.
The Asian lineage H5N1 and H7N9 have caused the most human infections. The WHO says since 2003, multiple countries have reported more than 860 human infections with HPAI A(H5N1) viruses, with about 53% of those cases resulting in fatalities. From 2014 to January 2023, 54 human cases of avian influenza A(H5N1) and 82 human cases of avian influenza A(H5N6) have been reported by Mainland China health authorities.
The WHO says the risk to humans remains low, and no sustained human-to-human transmission has been reported. The WHO confirmed in January 2023, influenza A(H5) viruses have not acquired the ability for sustained transmission among humans, thus the likelihood of human-to-human spread is low.
Human Avian Influenza Infections U.S.
On April 28, 2022, the state of Colorado reported the first influenza A (H5) virus infection in Montrose County. The CDC says this 'Colorado patient is the first human detection of any influenza A(H5) virus in the U.S. since 2016. In addition, the CDC publishes: Past Reported Global Human Cases with Highly Pathogenic Avian Influenza A(H5N1) (HPAI H5N1) by Country, 1997-2022.
Avian Influenza China
The Centre for Health Protection (CHP) of the Department of Health closely monitors human cases of avian influenza in the Mainland and again urges the public to maintain strict personal, food, and environmental hygiene locally and during travel. The CHP Avian Influenza Report report VOLUME 19, NUMBER 01, was posted on January 3, 2023. Furthermore, on January 5, 2023, the Alert Response Level under the CHP's Government Preparedness Plan for Influenza Pandemic (2014) was activated.
The public may visit the CHP's weekly Avian Influenza Report, global statistics, and affected areas of avian influenza for updated news.
Avian Influenza Americas
On January 18, 2023, the WHO stated the Ecuador case is the first human infection caused by the avian influenza A(H5) virus in Latin America and the Caribbean region. The Canadian Food Inspection Agency reported H5N1 outbreaks beginning in December 2021, marking the first identification of HPAI in the Americas since June 2015.
The Pan American Health Organization/WHO (PAHO/WHO) recommended on December 3, 2022, that the Member States strengthen coordination between sectors involved in alerting and responding to zoonotic events and implement the necessary measures to contain emerging pathogens that may put public health at risk. PAHO/WHO recommends monitoring the occurrence of influenza-like illness or severe acute respiratory infection in people exposed to birds (domestic, wild, or in captivity) infected with influenza viruses.
On November 28, 2022, Venezuela confirmed its initial HAPI outbreak. And the Central American country of Ecuador reported its first HAPI outbreak in poultry on November 25, 2022, likely part of the Eurasian H5N1 strain found in South America. A nine-year-old girl in central Ecuador was infected with the A-H5 strain of avian influenza in January 2023. In addition, other countries, such as Belize, Columbia, Mexico, and Peru have confirmed HAPI cases.
Avian Influenza India
Thiruvananthapuram's Health Minister confirmed a bird flu infection in Trivandrum Azhur Gram Panchayat in southern India in January 2023. In response, the local Health Departmenwarnedto all the districts.
Avian Influenza Spain
The WHO reported on November 4, 2022, public health authorities in Spain reported the detection of influenza A(H5N1) in two poultry workers on a single farm. However, no evidence of human-to-human transmission of the influenza A(H5N1) virus in this event has been identified to date.
Spanish researchers reported in Eurosurveillance on January 19, 2023, the first known HAPI A(H5N1) outbreak in farmed mink in the Galicia region. The new variant puts bird flu in “uncharted territory”, says Wendy Puryear, a virologist at Tufts University in Massachusetts, on January 24, 2023.
Avian Influenza Vietnam
On October 17, 2022, the Vietnam Central Institute of Hygiene and Epidemiology reported positive results for influenza A(H5) from a specimen of a 5-year-old female patient in Phu Tho. This is the latest human case of influenza A(H5) in Vietnam since February 2014. Accumulating from 2003 to now, the whole country recorded 128 cases of influenza A(H5) infection.
Avian Influenza United Kingdom
An Avian influenza Prevention Zone was declared by the U.K. government across Great Britain on October 17, 2022, making it a legal requirement for all bird keepers to follow strict biosecurity measures. The U.K. Health Security Agency (UKHSA) advises that the risk to public health from the virus is very loIn addition, the Food Standards Agency recommends that avian influenzas pose a very low food safety risk for consumers.
As of October 24, 2022, the U.K. says residents should register poultry, even if only kept as pets. All bird keepers (whether you have pet birds, commercial flocks, or just a few birds in a backyard flock) must closely watch on them for signs of disease and maintain good biosecurity at all times. If you have any concerns about the health of your birds, seek prompt advice from your vet.
On October 10, 2022, the U.K. announced it had faced its largest-ever bird flu outbreak, with over 170 cases confirmed since late October 2021. The wild bird risk across Great Britain is maintained at medium, and the risk to poultry with stringent biosecurity is maintained at low. However, birdkeepers should follow enhanced measures at all times to prevent the risk of future outbreaks.
HAPI Infections in Mammals
As of 2023, surveillance data does not suggest widespread mammalian adaptation of the HAPI virus (low to moderate confidence). And there is insufficient information to judge the risk of asymptomatic or mild disease due to limited testing in human contact with infected birds.
The USDA listing, as of January 18, 2023, includes about 110 H5N1 detections in mammals (skunks, bears, raccoons, red foxes) that were confirmed during 2022. The USDA has reported four detections from three states involving three bear species in 2022.
The Montana Department of Fish, Wildlife, and Parks confirmed on January 17, 2023, three juvenile grizzly bears tested positive for HAPI. In 2022, a fox and a skunk also tested positive for HPAI in Montana. The State of Alaska reported on December 13, 2022, HPA had been detected in a brown bear cub on Kodiak Island, Alaska. On November 18, 2022, HPAI was detected in a black bear in Southeast Alaska. The first confirmation was in June 2022. And on August 30, 2022, the first case of H5N1 infection in a black bear was confirmed in Quebec, Canada.
In May 2022, two red fox kits in Ontario, Canada, tested positive for HPAI. Those kits were the first reported cases of the current HPAI outbreak in a wild mammal in North America. Red fox infections were confirmed in Michigan and Minnesota, bald eagles in Alaska, skunks and raccoons in Washington, and seals near Maine in July 2022. In addition, Norway reported H5N1 for the first time in mammals (foxes), according to a study posted on July 25, 2022.
