Norovirus in a Rental: A Host's Turnover Guide
A guest left sick, or messaged you afterwards to say they had "the stomach bug." Your next check-in is tomorrow. This page is the CDC cleanup protocol translated into a whole-unit turnover — what to clean and with what, why the calendar matters more than the disclosure, and the three things hosts most often get wrong.
Why an ordinary changeover is not enough
Three facts from CDC decide everything below. Norovirus "can persist on surfaces for days or weeks and is resistant to many common disinfectants." The infectious dose is tiny — CDC says "it only takes a few norovirus particles" to make someone sick. And hand sanitizer "does not work well against norovirus" and "is not a substitute for handwashing," because norovirus has no lipid envelope for alcohol to disrupt. A standard wipe-and-vacuum turnover does not reliably clear it, which is why back-to-back bookings are the real hazard, not the previous guest.
The turnover, in order
This is CDC's household and outbreak guidance applied to a rental unit. The sequence matters: ventilate and protect yourself first, deal with any visible soiling before general cleaning, then disinfect, then laundry, then hands.
- Put on disposable gloves before you touch anything. Add a mask if you are cleaning up vomit — CDC notes that vomiting aerosolises virus, and droplets settle on nearby surfaces. Open windows if you can.
- Deal with visible vomit or stool first, and do not dry-handle it. Cover, absorb and remove with disposable materials, bag it, and disinfect the area and everything within a few feet of it. Vomit droplets travel further than most people assume — the classic hotel-restaurant investigation found attack rates that fell in step with each table's distance from the person who vomited (Marks et al., Epidemiol Infect 2000).
- Disinfect every hard, non-porous surface with bleach. CDC's concentration is 5–25 tablespoons of household bleach (5–8%) per gallon of water — approximately 1,000–5,000 ppm — or an EPA-registered product carrying a norovirus claim. Mix fresh. Leave surfaces visibly wet for the contact time the product states.
- Work the high-touch list, not just the visible mess. Toilet seat, flush handle and the floor around the toilet; taps, sink, bath and shower controls; every door handle and light switch; the fridge handle, kettle, microwave and coffee machine; remote controls; stair rails; the lock keypad. These are the surfaces a normal changeover skims.
- Laundry: bag, do not shake. Wear gloves, remove and bag soiled linens and towels carefully — shaking aerosolises virus — then machine wash with detergent in hot water at the maximum available cycle length and machine dry on the highest heat setting. CDC supports no cold-water or air-dry alternative.
- Kitchen items. Dishes, glassware and utensils through a hot dishwasher cycle. Discard any opened or unwrapped food the sick guest may have handled; a sealed, unopened item is not the risk.
- Soft surfaces last, and honestly. Steam-clean carpet and upholstery where it is practical. Where it is not — a soiled mattress, a heavily contaminated rug — replacement is the reliable answer, and pretending otherwise is the most common corner cut.
- Remove gloves inside-out, bin them, and wash your hands with soap and water for 20 seconds. Not sanitizer. This step is not optional for the person who did the cleaning.
If you are the one who got sick
Do not clean, cook or handle another guest's linens while symptomatic or for at least 48 hours after symptoms stop. That is the FDA Food Code standard for food workers with norovirus and the CDC's advice generally, and the reason is shedding: virus output is highest around and just after symptoms, and CDC states you can still spread norovirus for two weeks or more after you feel better. Get someone else to do the turnover.
What does not work — and keeps appearing in host advice
| Commonly used | Works against norovirus? | Why |
|---|---|---|
| Alcohol hand sanitizer | No — supplement only | CDC: "does not work well against norovirus"; no lipid envelope for alcohol to disrupt |
| Quat ("quaternary ammonium") wipes without bleach | Not reliably | Not effective against norovirus unless the product carries a registered norovirus claim |
| A wipe registered against COVID-19 | Not necessarily | EPA registration is pathogen-specific; a SARS-CoV-2 claim is a claim about an enveloped virus |
| Vinegar or "natural" cleaners | No | Not a disinfectant; no registered virus claim |
| Steam-only, no disinfectant | Partly | Useful for carpet and upholstery that cannot be laundered; not a substitute for bleach on hard surfaces |
| Chlorine bleach at CDC's concentration | Yes | CDC's specified agent; 5–25 tbsp per gallon, applied to hard non-porous surfaces |
The cross-virus version of this table — including how long each virus survives on a surface, and why the answer differs so much between norovirus and COVID — is on the network hub: what kills viruses, by virus type.
The calendar question
The question hosts actually ask is "how long do I have to block?" There is no published answer, and it is worth saying why rather than inventing a number.
No health authority publishes a vacancy period for a room or a rental unit after norovirus. CDC's standard is a completed disinfection, not elapsed time — the unit is safe when the work is done, not when a clock runs out. What sets a realistic block is therefore the work: a whole-unit bleach turnover with contact time on every hard surface, full hot-wash laundry, a dishwasher cycle and any soft-furnishing treatment is a half-day of work, not the 60–90 minutes a normal changeover assumes. Hosts who get caught out are almost always the ones with a same-day back-to-back booking.
Two related things are set by your platform and your own terms, not by public health guidance, and both change: the extenuating-circumstances policy that governs whether you can cancel a booking without penalty, and your own cancellation and refund terms for the guest who was ill. Check those on the platform directly at the time — do not rely on a summary, including this one.
Longer-term rentals and multi-unit buildings
The protocol above is the same for a landlord dealing with a tenant illness, but the legal frame is different and this page cannot resolve it. Who is responsible for cleaning a private unit after a tenant's illness, what a landlord may enter for, and what counts as habitability are matters of state and local landlord-tenant law and of your lease — not of CDC guidance. If you are directing paid cleaners into a unit contaminated with body fluids, that is also an occupational-safety question for your state authority.
What does generalise: in a multi-unit building, shared surfaces are the ones that matter. Lobby and stair handrails, lift buttons, shared laundry machines — particularly the machine doors, dials and folding surfaces — and any shared bathroom. Norovirus outbreaks in congregate settings are the most commonly reported kind in the US, and over half of reported US outbreaks occur in long-term care facilities; the mechanism there is shared surfaces and shared food service, and a residential building has both.
If you serve food to guests
Breakfast service, a shared kitchen you cook in, a welcome basket you assemble by hand — any of these puts you under food-safety rules. The FDA Food Code standard is that a food employee diagnosed with norovirus is excluded, and reinstatement requires regulatory approval plus one of: medical documentation of freedom from infection, or more than 48 hours since becoming asymptomatic (§2-201.13(D)). Our norovirus food safety page sets out the rules in full.
Frequently Asked Questions
How long should I block my calendar after a guest had norovirus?
There is no published quarantine period for a rental unit — the standard is a completed disinfection, not elapsed time. What sets a realistic block is the work: a full bleach turnover with contact time, hot-wash laundry and soft-furnishing treatment is a half-day, not a 90-minute changeover. Avoid the same-day back-to-back. The reason it matters is that norovirus persists on surfaces for days or weeks and resists many common disinfectants, so an ordinary clean will not reliably clear it.
What disinfectant should I use?
Chlorine bleach at CDC's concentration — 5 to 25 tablespoons of household bleach per gallon of water (≈1,000–5,000 ppm) — or an EPA-registered product with a specific norovirus kill claim. Quat wipes without bleach, alcohol wipes and vinegar are not reliably effective. A product registered against COVID-19 is not automatically registered against norovirus.
Do I have to tell the next guest?
No health authority requires it, and after a proper bleach turnover and hot-wash laundry there is no ongoing hazard to disclose. The question that does have consequences is the reverse one — your cancellation and refund terms if you need to block a booking to do the work — and that is set by your platform's policy and your house rules, which you should check directly.
Can norovirus spread through the laundry?
Yes, mostly in the handling. CDC's instruction is gloves on, bag soiled items without shaking them, machine wash with detergent in hot water at the maximum cycle length, machine dry on the highest heat. There is no CDC-supported cold-water or air-dry alternative, and you wash your hands with soap and water afterwards even though you wore gloves.
Should I hire a professional?
For a single-unit turnover the CDC protocol is what a professional applies, and time is the limiting factor rather than equipment. Call one for contaminated soft furnishings or mattresses that cannot be laundered, a vomiting incident in a shared building area, or a cluster across consecutive guests — which means something in the unit was missed.
Could the unit itself have made the guest sick?
Possibly, and it is worth ruling out if more than one guest reports illness. The routes are a contaminated surface left from an earlier guest, food handled by someone infected, or — rarely — water. A single report is far more likely to be community exposure that happened to surface during the stay, given the two-week incubation-to-shedding window. A cluster across consecutive stays is a different signal and is the case for a deep clean and a look at the water and food chain.
