The virus that causes COVID-19 can end up on your clothes, but fabric is a poor home for it, and catching COVID this way is very unlikely. The virus spreads mainly through the air you breathe near an infected person, and US health officials rate the risk from touching surfaces as low.1Respiratory Therapy. CDC: Risk of COVID-19 Surface Transmission Low Absorbent fabrics like cotton break the virus down faster than hard surfaces such as phones, doorknobs, and counters, so your clothes are less of a concern than the objects around you.
How Virus Ends Up on Clothing
Tiny particles that float in the air mostly follow the air currents around your body instead of landing on your clothes.2Occupational Health & Safety. Where Does the Virus Live? Not on Your Hair, Clothes or Shoes As you move, you push air aside, and most small particles get carried along with it.3Occupational Health & Safety. Where Does the Virus Live? Not on Your Hair, Clothes or Shoes For droplets to land on your clothing, someone usually has to cough, sneeze, or spray spit while talking close to you.4Occupational Health & Safety. Where Does the Virus Live? Not on Your Hair, Clothes or Shoes
Large droplets are the main way virus reaches clothing. When someone coughs or sneezes face to face, many large droplets fall below chest height and land on clothes or shoes instead of the face.5PubMed Central. Numerical modeling of the distribution of virus carrying saliva droplets during sneeze and cough Saliva droplets on fabric dry within several minutes and leave small dried spots behind.6PubMed Central. Transmission risk of viruses in large mucosalivary droplets on the surface of objects: A time-based analysis
Holding or hugging someone who is ill is much more likely to transfer droplets than passing them in a store. A short walk through a crowded space rarely leaves anything meaningful on your clothes.
The front of your clothes catches most of the action, because droplets from a cough travel forward and downward. If you are the one who is sick and you cough into your elbow, your own droplets land on your sleeve, which is worth washing.
A visible wet spot from a cough is not an emergency. Avoid touching it and then your face. You can keep wearing the clothes for the moment and change when it’s convenient, as long as you wash your hands before touching your eyes, nose, or mouth.
Being close enough to a sick person to get droplets on your clothes also means you were close enough to breathe in their breath, which carries the larger risk. If you were near someone with COVID, your concern should be the exposure itself, such as testing and watching for symptoms, more than the state of your outfit.
How Long COVID Lasts on Fabric
Absorbent fabric kills the virus fastest. In one study, live virus could not be recovered from cotton even right after it dried on the fabric.7PubMed Central. Survival of SARS-CoV-2 on Clothing Materials Polyester and faux leather lost live virus within the first day in the same tests.8PubMed Central. Survival of SARS-CoV-2 on Clothing Materials Other tests found cotton can hold infectious virus anywhere from 2 hours to 4 days, while polyester held it for 1 to 3 days.9PubMed Central. Porous surfaces: stability and recovery of coronaviruses
Fabric dries droplets out quickly. It soaks a droplet into its fibers by wicking, so it dries much faster than a droplet sitting on glass or metal.10PubMed Central. Why coronavirus survives longer on impermeable than porous surfaces The virus needs moisture to stay infectious, so it breaks down sooner on cloth. It also does not appear to stick to fabric fibers or get trapped in the weave, so it is not hiding deep in the cloth.11PubMed Central. The Stability of Model Human Coronaviruses on Textiles in the Environment and during Health Care Laundering
Temperature makes a big difference. In dark lab conditions at 20°C (68°F), live virus lasted up to 14 days on cotton cloth but up to 28 days on glass, steel, and banknotes.12CSIRO. How long the virus can survive At 30°C (86°F), it lasted only 3 days on cotton.13CSIRO. How long the virus can survive At 40°C (104°F), it lasted less than 16 hours.14CSIRO. How long the virus can survive In another study, clothing kept live virus at least 96 hours at fridge temperature and at least 4 hours at room temperature, and none was found at body temperature.15PubMed Central. Modeling the stability of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on skin, currency, and clothing Warm conditions and the heat from your own body work against the virus. The survival numbers vary widely because studies used different fabrics, amounts of virus, temperatures, and ways of measuring, so no single figure is the right one.
Lab times also overstate real-life risk. Lab tests often place far more virus on fabric than a real cough leaves, and the samples sit dark and still, while real clothes face sunlight, movement, and body heat. A virus surviving in small amounts does not mean enough remains to infect someone. Studies of common office fabrics conclude they are unlikely sources of coronavirus spread in normal room conditions.16Indoor and Built Environment. Virus inactivation on common indoor contract fabrics
Setting clothes aside for a few days is a reasonable option if you can’t wash them right away. Warmth speeds the loss of infectious virus, so a heated home works better than a cold car or garage, where the virus can last longer.
Detecting Virus Is Not the Same as Being Infectious
Many surface tests look for genetic traces of the virus rather than live virus that can infect you. Finding genetic traces on a surface does not mean live virus is there.17PubMed Central. Persistence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Virus and Viral RNA in Relation to Surface Type and Contamination Concentration The virus loses its ability to infect much faster than its genetic traces fade.18PubMed Central. Survival of SARS-CoV-2 and bovine coronavirus on common surfaces of living environments On one cruise ship, genetic traces were found 17 days after sick passengers left.19PubMed Central. Survival of SARS-CoV-2 and bovine coronavirus on common surfaces of living environments
The common surface tests use a method that picks up genetic material, even from broken fragments of virus. A fragment cannot infect anyone. Growing virus in cultured cells is the test that shows whether a sample can infect, and it is slower and harder, so fewer studies do it. That’s why headlines about virus “on surfaces” can mislead: they often report genetic traces as if they were live virus.
Real sick people’s linens show the same pattern. In homes and care settings with infected people, genetic traces turned up on about 1 in 7 linens used by COVID patients.20PubMed Central. Potential risk of SARS-CoV-2 infection among people handling linens used by COVID-19 patients before and after washing No live virus was grown from any of the 700 samples taken.21PubMed Central. Potential risk of SARS-CoV-2 infection among people handling linens used by COVID-19 patients before and after washing Even in these settings, most linens had no traces at all, so sheets and towels can be washed the normal way instead of treated as hazardous waste.
Can Your Clothes Make Someone Sick
Clothes can carry virus-laden particles from a workplace to a car or home.22PubMed Central. Modeling Clothing as a Vector for Transporting Airborne Particles and Pathogens across Indoor Microenvironments But breathing in particles shaken loose from cotton clothing gave about 1,000 times less exposure than breathing the air at work.23PubMed Central. Modeling Clothing as a Vector for Transporting Airborne Particles and Pathogens across Indoor Microenvironments Even with synthetic fabrics that keep the virus alive longer, the exposure was still about 100 times lower.24PubMed Central. Modeling Clothing as a Vector for Transporting Airborne Particles and Pathogens across Indoor Microenvironments Risk from clothes after work was low unless you were in close contact with the contaminated clothing.25American Chemical Society (ACS). Modeling Clothing as a Vector for Transporting Airborne Particles and Pathogens across Indoor Microenvironments The risk rose mainly with close contact, such as burying your face in the clothing or handling it roughly.
Touching fabric moves little virus. When artificial skin was pressed against contaminated masks, some genetic traces transferred but no live virus did.26PubMed Central. Stability of Aerosolized SARS-CoV-2 on Masks and Transfer to Skin Washing your hands after handling clothes from a sick person is a cheap precaution that covers what small risk remains. Health officials rank surface spread well below direct contact, droplets, and airborne particles.27Respiratory Therapy. CDC: Risk of COVID-19 Surface Transmission Low Ventilation and distance from a sick person reduce your risk far more than worrying about fabric.
How to Wash Clothes After COVID Exposure
Regular detergent breaks down the virus’s fatty outer coating, which is what lets it infect cells. Water carries the broken pieces away, so washing works even at a modest temperature. Drying adds protection, with hotter and longer cycles cutting germ numbers more.28PubMed Central. Laundry Hygiene and Odor Control: State of the Science Laundry sanitizer products killed at least 99.9% more of the virus beyond washing alone, but a sanitizer is optional.29PubMed Central. Virucidal efficacy of laundry sanitizers against SARS-CoV-2 and other coronaviruses and influenza viruses30PubMed Central. Virucidal efficacy of laundry sanitizers against SARS-CoV-2 and other coronaviruses and influenza viruses
For a sick household member’s laundry, don’t shake the dirty items, since shaking can send particles into the air. Use the warmest water setting the fabric label allows and dry completely. Washing their clothes with the rest of the household’s laundry is fine. Wash your hands after handling dirty laundry, and wear gloves if you have them.
When you’re caring for someone with COVID, carry the hamper instead of hugging the bundle against your body. Wipe the hamper or use a washable liner. There’s no need to bleach everything or throw clothes away.
Changing at work and bagging uniforms keeps them separate on the drive home, and washing them separately on a hot cycle is a reasonable practice.31PubMed Central. Health care worker knowledge and attitudes towards uniform laundering during the COVID-19 pandemic
If a fabric can’t take hot water or a hot dryer, a normal wash with detergent on the warmest permitted setting is still adequate. Letting the item dry fully, ideally in sunlight or a warm room, adds more protection. For something too delicate for the machine, hand washing with detergent and then drying completely works.
Does the Type of Fabric Matter
Virus stayed infectious longest on plastic gowns and coveralls and shortest on cotton and polyester.32PubMed. The role of gowns in preventing nosocomial transmission of respiratory viruses: a systematic review Several hospital studies found short sleeves, cotton gowns, or no gowns protected staff about as well as standard gowns.33PubMed. The role of gowns in preventing nosocomial transmission of respiratory viruses: a systematic review In a hospital simulation, short-sleeved gowns with hand and arm washing prevented all staff contamination during a high-risk procedure, compared with 30 of 67 staff in standard gear.34PubMed Central. Reduction in transfer of micro-organisms between patients and staff using short-sleeved gowns and hand/arm hygiene in intensive care during the COVID-19 pandemic: A simulation-based randomised trial
Plastic gowns and coveralls don’t absorb liquid, so droplets stay as wet beads on the surface instead of soaking in and drying. A liquid-repelling gown still helps hospital staff by keeping fluids off their skin.
Short sleeves leave the forearms bare, where they can be washed, whereas long sleeves can carry virus that is hard to clean off. In the simulation, the washing step was a major part of why short-sleeved gowns worked so well, not the sleeve length alone. These results come from healthcare staff in high-risk procedures, so a caregiver at home faces much lower exposure.
At home, short sleeves let you wash your forearms along with your hands. Rain jackets and plastic aprons are worth wiping down or rinsing after close care.
Masks are fabric too. Wash reusable cloth masks like other clothes and handle used masks by the straps. Disposable masks are meant to be thrown away, not stored and reused.
Are Antiviral Fabrics Worth It
A silver-based coating cut virus by about 75% within 5 minutes and 98% after 2 hours in lab tests.35PubMed Central. Antiviral Activity of Silver, Copper Oxide and Zinc Oxide Nanoparticle Coatings against SARS-CoV-2 A copper oxide coating cut it by about 76% after 2 hours, while zinc oxide had little effect.36PubMed Central. Antiviral Activity of Silver, Copper Oxide and Zinc Oxide Nanoparticle Coatings against SARS-CoV-2 These results come from coated surfaces in the lab, not from clothes worn in daily life. Even the fast silver result took minutes to hours, so virus still sits on the fabric for some of that time.
The mixed results matter when choosing a product. Zinc oxide had little effect, so not every metal-based coating helps, and a label that says antimicrobial tells you very little. A product with silver or copper may reduce virus on the coated material, but that doesn’t mean it protects the wearer.
Before buying, check whether the maker tested against the coronavirus that causes COVID or only against bacteria or odor, since results don’t carry over. Look for whether the claim describes the fabric when new or after repeated washes, since coatings can wear off. Be cautious of any claim promising protection from COVID.
