As of March 10, 2021, a total of 22 people infected with the outbreak strain were reported from 7 states (see map). Illnesses started on dates ranging from December 18, 2020, to January 12, 2021.
Sick people ranged in age from 10 to 95 years, with a median age of 28, and 68% were female. Of 20 people with information available, 11 were hospitalized. Of 18 people with information, 3 developed a type of kidney failure called hemolytic uremic syndrome (HUS). One death was reported from Washington.
State and local public health officials interviewed people about the foods they ate in the week before they got sick. CDC analyzed the interview data and did not identify a specific food item as a potential source of this outbreak. People reported eating a variety of food items, including leafy greens, broccoli, cucumbers, and strawberries. However, none of the food items were reported significantly more by sick people in this outbreak when compared to healthy people in the FoodNet population survey.
