Avian influenza is an infection caused by avian (bird) influenza (flu) viruses. These influenza viruses occur naturally among birds. Wild birds worldwide carry the viruses in their intestines, but usually do not get sick from them. However, avian influenza is very contagious among birds and can make some domesticated birds, including chickens, ducks, and turkeys, very sick and kill them.
Scientists in a network of medical research institutions across the United States are set to begin a series of clinical trials to gather critical data about influenza vaccines, including two candidate H1N1 flu vaccines. The research will be under the direction of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
The recent global swine flu outbreak has underscored the critical need for good surveillance and rapid access to epidemiological data. The US military, starting with early monitoring efforts in the 1970s, has developed a broad-based influenza monitoring system. In an article published in the September 2009 issue of the American Journal of Preventive Medicine, researchers describe this little-known national jewel that has repeatedly made notable contributions to global influenza control through close collaboration with CDC, the Food and Drug Administration (FDA), the WHO, and many other partners.
Scientists say new research has shown that the new H1N1 influenza strain (swine flu) is somewhat less contagious than seasonal flu, but appears to be more able to cause stomach upsets.
According to a report published today, we must all share responsibility for preventing the spread of diseases such as swine flu, SARS, avian influenza, diarrhoeal and skin diseases, and even the common cold.
"The new swine influenza virus [H1N1], which appeared suddenly after years of warning about a potential pandemic of avian influenza, upset the WHO's assumptions that most people have the same understanding of the word pandemic," says the New York Times in a report that examines the difficultly health experts have had when attempting to agree upon what constitutes a pandemic.
New data on the persistence of avian influenza viruses in the environment has allowed a team of University of Georgia researchers to create the first model that takes into account both direct and indirect transmission of the viruses among birds. The model, which is detailed in the early online edition of the journal Proceedings of the National Academy of Sciences, has the potential to shed new light on how outbreaks begin in wild bird populations.
Sanofi Pasteur announced today it has received the first of what is expected to be a series of orders from the U.S. Department of Health and Human Services (HHS) to commence production of a vaccine to help protect against the new influenza A(H1N1) virus.
In just two weeks from the time the first patient virus samples were made available, Singapore scientists report an evolutionary analysis of a critical protein produced by the 2009 H1N1 influenza A virus strain.
WHO Director-General Dr Margaret Chan and United Nations Secretary-General Ban Ki-moon met with over 30 vaccine manufacturers from developing and developed countries at WHO headquarters today.
Avian influenza viruses do not thrive in humans because the temperature inside a person's nose is too low, according to research published today in the journal PLoS Pathogens.
It is expected that the upcoming World Health Organisation's (WHO) annual assembly will be dominated this year by the emergence and spread of the new influenza virus H1N1 (swine flu).
Pregnant women and newborns are at greatest risk in a flu epidemic, but more planning must be done to ensure that they receive priority treatment should an outbreak occur, according to a University of Pittsburgh Medical Center (UPMC) and University of Pittsburgh study.
The latest update (# 26) from the World Health Organisation (WHO) reports that as of the 12th of May 2009, 30 countries have officially reported 5,251 cases of influenza A (H1N1) infection.
The latest update (# 24), from the World Health Organisation on influenza A H1N1 (swine flu) says as of the 10th May 2009, 29 countries have now officially reported cases of human infection.
The U.S. Agency for International Development (USAID) is convening a group of civil society organizations in Addis Ababa, Ethiopia, in a regional exercise that will kick off the implementation stage of its Humanitarian Pandemic Preparedness initiative.
New research from the University of Leicester and University Hospitals of Leicester NHS Trust warns of a six-month time lag before effective vaccines can be manufactured in the event of a pandemic flu outbreak.
A new study by University of Maryland researchers suggests that the potential for an avian influenza virus to cause a human flu pandemic is greater than previously thought. Results also illustrate how the current swine flu outbreak likely came about.
Swine influenza or Swine flu is a respiratory disease commonly found in pigs which is caused by type A influenza virus - it causes high levels of illness in pigs but low death rates and while swine flu viruses may circulate among swine throughout the year, most outbreaks occur during the autumn and winter months similar to flu outbreaks in humans.
An in-depth analysis of blood from patients recovering from the H5N1 avian influenza virus has provided important insights into how to combat the potentially lethal virus.
The U.S. Food and Drug Administration today cleared for marketing a new, more rapid test for the detection of influenza A/H5N1, a disease-causing subtype of the avian influenza A virus that can infect humans.
