This year's outbreak of West Nile virus is the worst since the illness was first observed in the United States in 1999, officials from the U.S. Centers for Disease Control and Prevention said Wednesday. The number of confirmed cases rose by 25% last week to 1,993 -- although only an estimated 2% to 3% of cases are reported to the government. Those are generally the most serious infections: Most people who contract the virus do not develop severe symptoms, and many never even know they were infected.

Federal officials said Tuesday that they fear an outbreak of dengue fever in Florida after a survey of Key West residents found that at least 5% had been infected or exposed to the virus. With the exception of a handful of isolated cases along the Texas-Mexico border, there had previously been no cases in the United States since 1946 and no outbreak in Florida since 1934. Dengue fever, which is characterized by a fever of 104 to 105 degrees, a widespread rash, headache, fatigue and muscle aches, is the most common disease caused by mosquito-transmitted viruses in the world.

A reusable grocery bag left in a hotel bathroom caused an outbreak of norovirus-induced diarrhea and nausea that struck nine of 13 members of a girls' soccer team in October, Oregon researchers reported Wednesday. The outbreak also affected many family members after the team returned home. Norovirus is a common, easily spread virus that causes various forms of gastric distress. It is "the perfect human pathogen" because it is highly contagious, rapidly and prolifically spread, produces limited immunity and is only moderately virulent, which allows it to continue spreading, said Dr. Aron J. Hall of the Centers for Disease Control and Prevention in an editorial accompanying the report in the Journal of Infectious Diseases.
