What are infection control measures for GI outbreaks?

Question

Hello doctor,

My entire assisted living facility, where I work as a nurse, is currently facing a serious gastrointestinal outbreak. It started in the memory care unit yesterday and has quickly spread throughout our facility, which houses 87 residents. The symptoms include severe vomiting, intense diarrhea, and rapid dehydration. My primary concern is for our elderly residents who have multiple health issues. Despite our efforts to keep them hydrated with oral electrolyte solutions, many are unable to retain fluids and have become critically dehydrated. We've already had to send three residents to the hospital, but our local emergency room is becoming overwhelmed. With our medical director out of town, I am the charge nurse in charge of making containment decisions. What infection control measures should we put in place immediately? At what point should we consider sending additional residents to the hospital? How can we safeguard our limited staff from getting infected?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Norovirus infection is an extremely contagious condition that typically resolves on its own, with symptoms persisting for approximately four to five days. A single source of infection can lead to widespread transmission among all household members.

If fluid intake is not adequately maintained, dehydration can become a serious concern.

Signs of severe dehydration include:

Unusual lethargy or decreased activity.
Pale, sunken eyes.
Cold extremities.
Increased heart rate and rapid breathing.
Irritability, drowsiness, or confusion.
Dark yellow urine or infrequent urination.
Decreased skin elasticity.

Should any of these symptoms be observed in patients, it is imperative to seek emergency medical care for intravenous fluid administration.

Recommendations:

Utilize oral rehydration solutions (ORS), increase fluid consumption, and avoid sugary beverages.
Administer antiemetics such as ondansetron for nausea and vomiting.
Use Imodium to manage diarrhea.
Antispasmodics, such as a combination of Dicyclomine tablets and Paracetamol, should be considered.
Consume easily digestible foods such as rice, soups, toast, and fruits.
Incorporate yogurt to help maintain normal gut flora.

Preventive measures include practicing good hygiene, such as thorough handwashing, properly cooking meat and vegetables, and ensuring food is cleaned adequately before preparation. Due to the highly contagious nature of norovirus, disinfecting contaminated areas is essential. This can be accomplished by following these steps:

Initial Cleaning: Wear disposable gloves to protect yourself and others. Clean the area with soap and water to eliminate visible dirt and debris before disinfecting.
Select an Appropriate Disinfectant: A diluted bleach solution (1/3 cup of bleach in 1 gallon of water) is effective. Ensure the solution is fresh and that the area is well-ventilated during application.
Disinfecting Process: Allow the disinfectant to remain on the surface for the recommended duration (typically 5-10 minutes) to effectively eradicate the virus.
Surface Wiping: After the disinfectant has been allowed to sit, wipe the surface with clean paper towels or disposable cloths.
Laundering Contaminated Fabrics: Wash any affected fabrics, including clothing, bedding, or towels, in hot water (at least 140°F or 60°C) with detergent.

I hope this information helps you.
