Migration routes hold key to bird flu spread, global study finds

Monitoring the migration routes of wild birds could help to provide early warning of potential bird flu outbreaks, experts say. The recommendation follows new research that shows migrating birds can help to spread deadly strains of avian flu around the world. Some strains of bird flu viruses are highly lethal in birds they infect and […]

Prime-boost H7N9 influenza vaccine concept promising in clinical trial

Prime-boost H7N9 influenza vaccine concept promising in clinical trial

In clinical trials, several candidate H7N9 pandemic influenza vaccines made from inactivated viruses have been shown to be safe and to generate an immune response. However, scientists believe for practical use, these potential vaccines would require multiple doses or the addition of adjuvants, which enhance the immune response. With hopes of making one dose of […]

Avian influenza expert raises concerns as USDA stockpiles vaccines

The U.S. Department of Agriculture is creating a stockpile of avian influenza vaccines, but an expert suggests careful consideration of the strategy and cautions that the strain of the next outbreak is unknown. Wild birds are typically the source of the introduction of the virus to backyard and commercial poultry flocks, which makes it very […]

Flexible future of point-of-care disease diagnostic

Flexible future of point-of-care disease diagnostic

The world-wide deployment of biomedical devices for health monitoring, point-of-care diagnostics and environmental sensing is hampered by their high cost that is not readily affordable for e.g. developing countries. The primary task is therefore to reduce the price of the devices and allow for their high-volume delivery in a cost efficient manner, e.g. container transportation. […]
