Don’t bring it in, don’t take it out, don’t spread it around

The dull checklist behind the three sentences we say at the door: hand hygiene, PPE order, vaccination, observation, zoning, cleaning.

Older bodies don’t fight off infection the way younger ones do. A single case can turn into an outbreak in a matter of days. The three words we say to each other at the door of the day-care center are the same three: don’t bring it in, don’t take it out, don’t spread it around.

What follows is the working checklist behind those three words. It’s boring on the page. It saves lives on the floor.

1. Standard precautions

The starting premise is simple: assume every person’s blood, body fluids, secretions, non-intact skin, and mucous membranes are potentially infectious. Treat everyone the same way. This is the WHO standard, and it is standard for a reason. You don’t want your caregivers guessing whom to protect against.

2. Hand hygiene — five moments (WHO)

• 1. Before touching a resident.
• 2. Before a clean or aseptic task.
• 3. After any risk of exposure to body fluids.
• 4. After touching a resident.
• 5. After touching anything in the resident’s surroundings.

Alcohol-based rubs are the default. When the hands are visibly soiled, wash with soap and running water.

3. PPE, and the order you take it off

Gloves, masks, gowns, eye protection — choose to fit the task. What people forget is the sequence for removal, which is where cross-contamination sneaks back in. Gloves come off first. Hand hygiene comes at the very end, every time.

4. Vaccination

The main vaccines for older adults in Japan: influenza (every autumn), pneumococcal (every 5 years), COVID-19, shingles, and RSV (older-adult formulation). Staff vaccination rates matter as much as resident rates. A facility’s inside transmission tracks with its lowest-vaccinated shift.

5. Watching for the earliest signs

Fever, cough, diarrhea, vomiting, loss of appetite, unusual lethargy, new skin rash. Routine vital-sign checks are half of it. Sharing the observation in the care record is the other half.

I want to add one more: the caregiver’s instinct that something’s “off.” That is a real piece of information, and worth writing down even when the numbers look normal.

6. Norovirus, specifically

Extraordinarily infectious. Spreads from vomit and stool. Alcohol won’t kill it. Chlorine will — a 0.1% sodium hypochlorite solution is the standard. Keep a vomit-response kit (gloves, mask, apron, newspaper, paper towels, chlorine solution) stocked on every unit, not just in the office.

7. Zoning during an outbreak

Two or more residents with the same symptoms in a short window? Treat it as an outbreak. Notify the local public health center. Inside the facility, divide space into red (confirmed positive), yellow (suspected), and green (clean). Staff assignments, movement paths, and equipment all get color-coded. The time to write that protocol is before you need it, not during.

8. Environmental cleaning

High-touch surfaces — doorknobs, handrails, toilet fixtures, dining tables — get wiped down multiple times a day. Air out each room 5 to 10 minutes, several times a day. Keep humidity between 50% and 60%; viruses do worse in that range.
