A study shows that drug-resistant mutations have been identified in patients infected with the avian H7N9 influenza A virus.
Almost genetically identical strains of H7N9 avian influenza were isolated from a man in eastern China and his daughter, both who died of the illness.
H7N9 influenza A, a strain of avian flu not previously known to infect humans, has sickened seven and killed two in China.
Although no evidence exists of sustained ongoing human-to-human H7N9 transmission, health officials are taking steps to prepare for a potential pandemic.

"This is the first new antiviral flu treatment with a novel mechanism of action approved by the FDA in nearly 20 years," said FDA Commissioner Scott Gottlieb, MD.
Immunologic priming and MF59-mixed vaccine demonstrated effective immune responses against strains of the avian flu.
Doubling the dose of oseltamivir has no virological or clinical advantage compared with standard-dose treatment for children with severe influenza.
OVERVIEW: What every clinician needs to know Pathogen name and classification Influenza viruses (types A, B, C) are segmented, negative-strand ribonucleic acid (RNA) viruses in the Orthomyxoviridae family. Influenza A viruses of various subtypes infect many animal species (e.g., birds, swine, horses, dogs, marine mammals, and felids) in addition to humans. Influenza A viruses are…
What every physician needs to know: Pneumonia is the fourth leading cause of death in the world, accounting for about 5% of deaths annually. Over the last decade, community-acquired viral infections of the lung have captured media and public attention after pandemic outbreaks of the severe acute respiratory syndrome (SARS) coronavirus of 2002-2003, the avian…
