Health officials have confirmed that two people from Snohomish County have been infected by the same type of salmonella that has sickened more than 1,000 people nationally.
The man and the woman, both in their 50s, were tested for the infection in late May or early June. But test results were just completed, showing that the salmonella that sickened these two people is the same strain that has sickened people nationally, Snohomish Health District spokeswoman Suzanne Pate said Wednesday.
Most people infected with salmonella develop diarrhea, fever and abdominal cramps 12 to 72 hours after infection. The illness usually lasts four to seven days. Although most people recover without treatment, severe infections may occur. Infants, the elderly and those with impaired immune systems are more likely to develop severe illness.
Federal agencies are still trying to identify the source of the outbreak, which is one of the worst food-borne-disease outbreaks in years.
