Defective viral genomes and severe influenza
By Vincent Racaniello
The virulence of a virus - its capacity to cause disease - is determined by both viral and host factors. Even among healthy individuals, infection with a particular virus may have different outcomes ranging from benign to lethal. The study of influenza viruses that cause mild or fatal outcomes reveals ...

A breath of fresh influenza virus
By Vincent Racaniello
Influenza virus may be transmitted among humans in three ways: by direct contact with infected individuals; by contact with contaminated objects (called fomites, such as toys, doorknobs); and by inhalation of virus-laden aerosols. A recent study suggests that normal tidal breathing plays a substantial role in aerosol transmission. Volunteers in a ...
