Cryptosporidiosis outbreak in a day-care center
Insights
Cryptosporidium oocysts were identified as the primary cause of diarrhea during a 1984 Texas day-care outbreak. This finding suggests Cryptosporidium is a significant pathogen in young children attending day-care centers.
Area of Science:
- Pediatric infectious diseases
- Microbiology
- Epidemiology
Background:
- Diarrheal outbreaks in day-care centers pose a significant public health concern.
- Identifying causative agents is crucial for effective outbreak control and prevention.
Purpose of the Study:
- To investigate the etiology of a diarrhea outbreak in a Texas day-care center.
- To determine the association between specific pathogens and diarrheal illness in young children.
Main Methods:
- Stool specimens were collected from 50 children in a day-care center during an outbreak.
- Samples were analyzed for the presence of parasites (Cryptosporidium, Giardia lamblia) and viruses (Echovirus 30).
- Statistical analysis was performed to correlate pathogen detection with diarrheal symptoms.
Main Results:
- Cryptosporidium oocysts and Giardia lamblia cysts were detected in 18 children each.
- Echovirus 30 was identified in 19 of 25 cultured stool specimens.
- Only Cryptosporidium oocyst presence was significantly associated with diarrheal illness.
Conclusions:
- Cryptosporidium is a likely cause of diarrhea in this day-care setting.
- The findings highlight the importance of Cryptosporidium surveillance in pediatric populations.
- Day-care centers may be environments where Cryptosporidium transmission is common.
Abstract:
An outbreak of diarrhea occurred in a day-care center in San Marcos, Tex, in August 1984. At the time of this study, the center was caring for 81 children aged 2 months through 5 years. A single stool specimen was collected from each of 50 children (62%). Cryptosporidium oocysts and Giardia lamblia cysts were each identified in stool specimens from 18 children. Three children had both parasites present in the same stool specimen. Echovirus 30 was identified in 19 of 25 stools cultured. Although three pathogens were circulating simultaneously in this group of children, only the presence of Cryptosporidium oocysts was associated with the occurrence of a diarrheal illness. Cryptosporidium may be a common cause of diarrhea in children who attend day-care centers.
