In childcare safety, the question of how to handle cases of Shiga toxin-producing E. coli (STEC) has been under scrutiny. However, a recent study suggests that current exclusion protocols for affected children may not need adjustment, despite an uptick in non E. coli -O157 cases.
Conducted by a team of researchers, the study delved into the duration of shedding among young STEC patients attending childcare facilities in England from March 2018 to March 2022. The findings, published in the journal Epidemiology and Infection, shed light on the complexities of managing these cases within educational settings.
Of the 1,033 confirmed STEC cases among children, 367 were linked to childcare attendance. Notably, both E. coli O157 and non E. coli -O157 strains were observed, with E. coli O26:H11 and E. coli O145:H28 emerging as the most prevalent non E. coli -O157 variants.
The median age of affected children was 3 years old, with diarrhea reported as the primary symptom in a significant majority. Tragically, 37 patients developed hemolytic uremic syndrome (HUS), and two fatalities were recorded.
One key finding was the median shedding duration of 32 days, regardless of E. coli strain. Notably, a quarter of cases took over six weeks to clear the infection fully, with some individuals shedding for as long as 142 days.
Despite these prolonged shedding periods, the study found that current exclusion practices, which mandate clearance through consecutive negative fecal specimens, generally aligned with the observed shedding durations. However, there were instances where children were excluded from childcare for longer than necessary, often due to delays in obtaining follow-up samples.
Challenges in implementing exclusion protocols were apparent, with parental dissatisfaction, financial strain, and logistical difficulties among the most common hurdles. Effective communication emerged as a vital strategy for managing these challenges, underscoring the importance of clear and transparent guidelines.
Notably, the study revealed a median delay of 10 days from symptom onset to formal exclusion by public health authorities, suggesting room for improvement in response times.
In light of these findings, researchers concluded that current exclusion guidance in England remains valid, providing a necessary balance between public health protection and minimizing disruption to families and communities. However, ongoing efforts to refine these protocols and understand their impact on children and parents are underway, ensuring that childcare facilities remain safe environments for all.
