The current surveillance strategy for avian influenza viruses is piecemeal, risking the detection of important virus sources or subtypes. A UC Davis expert emphasizes the need to strengthen global surveillance to prevent future pandemics.
Researchers have identified seven new host species for H5N1 avian influenza, including four goose species and the common gull, in a study of over 36,000 wild migratory birds. The findings provide important insights into the ecology and epidemiology of various global strains of the virus.
A review article argues that migratory birds are not the primary source of H5N1 virus dispersal. Human commercial activities, particularly poultry trade, are the major factors behind the global spread of the virus. The study suggests that strict health control and better animal welfare measures can help prevent disease transmission.
H5N1 avian influenza is most likely to be introduced to the US through infected poultry trade, not migratory birds. The virus spread rapidly through Asia, Europe, and Africa, causing millions of chicken deaths and 153 human fatalities.
The H5N1 avian influenza has been detected in 55 countries, but critical information about wild birds is often recorded inaccurately or not at all. This lack of data can lead to unwarranted assumptions and conclusions that affect public perceptions and resource allocation.
The US Geological Survey (USGS) has developed a database and web application called HEDDS to share information on sample collection sites, bird species sampled, and test results. The database provides current information on wild bird sampling for early detection of highly pathogenic avian influenza (HPAI) in the United States.
The US government has approved a multi-million dollar surveillance network to track the avian flu virus overseas. The Global Avian Influenza Network for Surveillance (GAINS) will provide valuable forecasts on viral storms, enabling the prevention of avian flu spread and preparation for outbreaks.
Wildlife Conservation Society's field vets collected samples from hundreds of wild birds affected by H5N1 strain, helping to develop a human pandemic influenza vaccine. The collaboration highlights the importance of protecting wildlife diversity and monitoring their health for potential benefits to humankind.
A study by Cornell University ecologists found that cadmium from abandoned mines is affecting white-tailed ptarmigan birds in Colorado, causing brittle bones and damaged kidneys. The metal is also concentrated in willow plants, which the birds eat, leading to reduced reproductive success.
Researchers at Cornell University will use acoustic monitoring to count forest elephants in Africa, providing crucial information on population numbers and health. The project aims to support conservation efforts by tracking endangered species such as gorillas and rhinos.
Elementary students at Christiansburg Elementary School are participating in a wildlife mapping program, recording animal sightings and sending data to the state. The project uses GPS technology and bird specimens from Virginia Tech's Museum of Natural History to teach students about conservation and habitat patterns.
Researchers investigated beaver pond succession and its impact on waterfowl productivity, finding that ponds in the old active stage created the most valuable habitat for waterfowl broods. Beaver ponds also support a wide range of bird species, including marsh and song birds.
A new study found that nearly all of Georgia's surviving least tern pairs are nesting on artificial sites, such as rooftops or man-made sand hills. The researchers warn that without further protection, the Atlantic least tern is vulnerable to decline due to habitat loss and human activities.
