An outbreak of gastroenteritis in a psycho-geriatric hospital associated with a small round structured virus

Area of Science:

• Infectious Diseases
• Epidemiology
• Public Health

Background:

• Gastroenteritis outbreaks pose significant challenges in healthcare settings, particularly those with vulnerable populations.
• Psycho-geriatric facilities require specific infection control strategies due to patient demographics and potential complexities in care.

Purpose of the Study:

• To describe an outbreak of gastroenteritis in a psycho-geriatric hospital.
• To identify the causative agent and assess the outbreak's impact on patients and staff.
• To highlight challenges in implementing control measures within this specific healthcare environment.

Main Methods:

• Case identification and symptom monitoring across affected wards.
• Stool sample analysis for viral identification using electron microscopy.
• Epidemiological investigation to determine the extent and duration of the outbreak.

Main Results:

• An outbreak of gastroenteritis occurred, affecting 67 patients and 30 nurses across four wards over a 4-week period.
• Small round structured viruses, resembling the Norwalk agent, were identified in stool samples from four patients.
• The illness was characterized by mild symptoms, but the widespread nature presented significant challenges.

Conclusions:

• Small round structured viruses can cause significant outbreaks of gastroenteritis in psycho-geriatric settings.
• Effective control of such outbreaks is hampered by limited staff and inadequate isolation facilities.
• Enhanced infection control protocols and resource allocation are crucial for managing infectious disease outbreaks in long-term care facilities.
