Introduction to Public Health

The first time an influenza virus was found to be transmitted directly from birds to people, with infections linked to exposure to poultry markets. Six people in Hong Kong died. This virus was different because it moved directly from chickens to people, rather than having been altered by infecting pigs as an intermediate host. In addition, many of the most severe illnesses occurred in young adults similar to illnesses caused by the 1918 Spanish flu virus.
Law firms will lead the pack, with 30% expecting to add staff. Paralegals with four to six years' experience are in particular demand, as are attorneys who specialize in "lucrative areas like litigation, health care, bankruptcy, and foreclosure law," the report says.
