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.

Centers for Disease Control and Prevention officials have linked four more deaths to the fungal meningitis outbreak caused by a batch of tainted steroid medicine, bringing the total dead to 19. Two of the new deaths were in Tennessee, with one each in Virginia and Florida. Fungal meningitis is an extremely dangerous, non-contagious infection of the membranes that line the brain and spinal cord. It often causes the brain to swell. The announcement by the CDC came the same day Food and Drug Administration authorities raided the Massachusetts offices of New England Compounding Center, the company at the center of the scandal.

Shingles is typically thought of as a once-in-a-lifetime (miserable) experience. But wait! Shingles can recur, even among healthy adults. The illness is caused by the herpes zoster virus. While researchers have known that people with weak immune systems due to other illnesses can develop shingles a second time, healthy people were thought to be one-time-only victims. The illness causes a burning or tingling sensation in the skin in one area of the body followed by blisters that last a few weeks.

An outbreak of E. coli cases linked to a North Carolina fair is raising questions about the safety of petting zoos and animal exhibits. So far, Cleveland County Health Director Dorothea Wyant said 38 cases, including the death of a 2-year-old boy, have been linked to the Cleveland County Fair. Of the 16 adults and 22 children involved, eight were hospitalized. Many had stopped by to see the sheep, goats and pigs used for livestock competitions and in the "huge" petting zoo, Wyant said.

More than two months after declaring the outbreak over, the U.S. Centers for Disease Control and Prevention said an additional 43 people have been sickened by strains of salmonella linked to Foster Farms poultry. The new cases were reported between late February and March 18, bringing the total number of people sickened by the year-old national outbreak to 524, the CDC said Wednesday . The outbreak first surfaced last October when the U.S. Department of Agriculture issued a health alert warning consumers of salmonella linked to three Foster Farms processing facilities in Central California.

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.
