For most STIs, the answer is no. Chlamydia, gonorrhoea, HIV, syphilis, and herpes cannot realistically be transmitted through bed sheets, towels, or clothing. These organisms die quickly outside the human body and require direct skin-to-skin or sexual contact to spread.
The exceptions are pubic lice (crabs) and scabies, which can survive on fabrics for 24-72 hours and can be transmitted through shared bedding. Trichomoniasis has a small theoretical risk on very moist surfaces.

Which STIs Can Survive on Bed Sheets?
| STI | Survives on Fabric? | Risk from Bed Sheets |
|---|---|---|
| Chlamydia | No (dies immediately) | Zero |
| Gonorrhoea | No (extremely fragile) | Zero |
| HIV | No (cannot survive outside body fluids) | Zero |
| Syphilis | No | Zero |
| Herpes | Briefly (minutes on moist fabric) | Negligible |
| HPV | Possibly (more resilient) | Very low, theoretical |
| Trichomoniasis | Briefly on moist surfaces | Very low |
| Pubic lice | Yes (up to 48 hours) | Possible |
| Scabies | Yes (up to 72 hours) | Possible |
Why Most STIs Can’t Spread Through Bedding
Bacteria like Chlamydia trachomatis and Neisseria gonorrhoeae are extremely fragile outside the warm, moist environment of human mucous membranes. They die within seconds on dry surfaces like sheets, pillowcases, and towels. HIV is similarly fragile, becoming non-viable within minutes outside bodily fluids.
Even herpes, which is more resilient than many STI organisms, requires direct contact with mucous membranes or broken skin to establish infection. The viral load on a bed sheet would be far too low to cause infection by the time you came into contact with it.
Pubic Lice and Scabies: The Real Risk
These are the genuine concerns when sharing bedding:
Pubic lice (crabs)
Adult lice can survive away from the body for up to 48 hours. They can transfer from infested bedding to your body. Symptoms include intense itching in the pubic area. Treatment: over-the-counter insecticide lotions and washing all bedding and clothing at 60°C or above.
Scabies
Scabies mites can survive up to 72 hours on fabrics. They burrow into skin and cause intense itching, worst at night. They’re more commonly spread through prolonged skin-to-skin contact, but shared bedding can contribute. Treatment: prescription permethrin cream applied to the whole body.

Sharing a bed (sleeping beside someone) without sexual contact poses essentially no risk for any STI except pubic lice and scabies. STIs are transmitted through sexual contact, not through proximity or shared sleeping surfaces.
If you’re sharing a bed with someone who has pubic lice or scabies, wash all bedding, towels, and clothing at 60°C and avoid skin-to-skin contact until treatment is complete.
How to Stay Safe
- Wash shared bedding and towels at 60°C or above
- Don’t share underwear
- If you suspect lice or scabies, treat all bedding, clothing, and affected people simultaneously
- For actual STI protection, use condoms during sex and get tested regularly
Frequently Asked Questions
Can you get chlamydia from sharing a bed?
No. Chlamydia is transmitted through vaginal, anal, or oral sex. It cannot survive on bed sheets or towels.
Can you get HIV from blood on sheets?
No. HIV dies rapidly outside the body. Even if there were blood on sheets, the virus would be inactive by the time you encountered it. HIV requires direct contact with fresh infected blood or sexual fluids to transmit.
Should I wash hotel bedding before using it?
Hotel bedding should be laundered between guests. If you’re concerned about pubic lice or scabies, you can request fresh sheets. For STIs like chlamydia, gonorrhoea, and HIV, hotel bedding poses zero risk.
Can I catch an STI from a toilet seat?
No. This is a persistent myth. STI organisms cannot survive on hard, dry surfaces like toilet seats. Read more: Can you catch an STI from a toilet?
