Hosting Thanksgiving when a guest, or the host, is sick

A sick guest, or a sick host, is one of the most common reasons a Thanksgiving plan changes in the last 48 hours. What to do depends on the illness. CDC treats respiratory viruses (flu, COVID, RSV, colds) and norovirus (the usual "stomach bug") very differently, and the second one is mostly about the kitchen. This page is a host's summary of CDC's public guidance, not medical advice; a guest with a medical condition should follow their own doctor.

Which kind of sick?

	Cough, fever, cold or flu symptoms	Vomiting or diarrhea
Likely cause	Respiratory virus (flu, COVID, RSV, cold)	Often norovirus
CDC: when to rejoin others	After 24 hours with symptoms improving and no fever (without fever reducers)	Avoid preparing food or caring for others until 48 hours after symptoms stop
Then	5 days of added precautions: mask, distance, cleaner air, hygiene, testing	Wash hands with soap and water; virus can be shed for 2 weeks or more
Biggest host risk	Shared air in a crowded room	Hands, food and the bathroom

If a guest has cold, flu or COVID symptoms

Before the day. If a guest is still feverish or getting worse, CDC's guidance is to stay home. Make that easy: offer a video seat at the table, and a plate packed by the host to drop off or pick up later. Say it early, so nobody feels pushed to come sick.

If they are in the 5-day window. A guest who meets CDC's 24-hour test can rejoin others but should take added precautions for 5 days. For a host, that looks like:

• A well-fitted mask when close to others, with a spare at the door.
• A seat with more space, near an open window, and away from older guests and babies.
• Their own serving utensils, or one person serving everyone's plates, so the sick guest isn't handling shared spoons.
• A test before arrival, if they have one; CDC lists testing among the added precautions.

Clean up the air. CDC's cleaner-air steps: open windows or doors even a little, run kitchen and bathroom exhaust fans, set the HVAC fan to "on" rather than "auto" so air keeps passing through the filter, use a portable HEPA air cleaner, or move part of the gathering outdoors. A crowded living room with the windows shut is the room to fix.

Protect the higher-risk guests. CDC says these precautions matter most for people 65 and older and people with weakened immune systems. Tell those guests who was sick, so they can decide for themselves. The older guests guide has seating and pacing ideas.

If someone has a stomach bug

Norovirus spreads through hands, food and surfaces, so the kitchen rules are strict. From CDC:

• Whoever was sick does not cook. No preparing or handling food for others until at least 48 hours after symptoms stop. If that is the person bringing pies or the gravy, reassign the dish now; the potluck planner helps redistribute.
• Soap and water, not sanitizer. Wash for at least 20 seconds before cooking and eating and after the bathroom. Hand sanitizer can be used in addition, but CDC says it does not work well against norovirus.
• Clean up right away. Gloves on; wipe up with paper towels into a plastic trash bag; disinfect with a chlorine bleach solution of 1,000 to 5,000 ppm (CDC: 5 to 25 tablespoons of household bleach per gallon of water) or an EPA-registered disinfectant against norovirus; leave bleach on for at least 5 minutes; then clean again with soap and hot water.
• Laundry: remove soiled linens right away, don't shake them, wash on hot with the longest cycle, and dry on the highest heat.
• Food that might be contaminated goes in the trash. CDC notes norovirus can survive temperatures as high as 145°F and that contaminated food can look, smell and taste normal.

If the sick one is the host

The 48-hour norovirus rule applies to you too, and it is the hardest one: if you had a stomach bug in the days before Thursday, someone else should do the cooking. Options, in order of disruption:

1. Move the kitchen. Another household cooks; you host only, or host at their house.
2. Make it a potluck, with every dish made in other kitchens. The what-to-bring guide is the list to send.
3. Postpone. A turkey thawing in the fridge keeps for 1 to 2 days, per the thawing guide; a turkey that's been cooked keeps 3 to 4 days, per the leftovers guide.

With a respiratory illness, CDC's 24-hour test still applies. A host in the 5-day window can cook with careful handwashing, but should consider a mask while plating and leave the serving to someone else.

The guest bathroom and the overnight guest

Stock every sink with soap and paper towels, put out a lidded bin, and keep a cleanup kit (gloves, bleach, a trash bag) under the guest-bathroom sink. If a sick guest is staying over, give them their own towel and, if you can, their own bathroom; the overnight guests checklist has the rest of the setup. And on the day, the usual buffet food-safety rules still apply.
