High heat can kill the coronavirus that causes COVID-19. Research argues that exposing a surface to a temperature the at least 158°F (70°C) for 5 minutes deactivates the virus.

You are watching: How hot does it have to be to kill a virus


This information originates from a 2020 laboratory study.

However, warmth may no be a practical or reliable technique of protecting against the SARS-CoV-2 virus for number of reasons. In house settings, appliances and hot water faucets usually cannot gain hot sufficient to provide the temperatures compelled to kill SARS-CoV-2.

Read on come learn more about even if it is heat can kill the novel coronavirus, SARS-CoV-2, and when and also how human being can use heat to stop its spread.

Stay informed with live updates on the current COVID-19 outbreak and also visit ours coronavirus hub for much more advice ~ above prevention and treatment.

An infection v the SARS-CoV-2 virus, i m sorry is a form of coronavirus, reasons COVID-19. Restricted research suggests that, similar to various other coronaviruses, SARS-CoV-2 is perceptible to high temperatures.

Authors that a 2020 activities study found that exposing a surface with SARS-CoV-2 ~ above it come a temperature the 158°F (70°C) because that 5 minutes deactivates the virus. This corresponds to the temperatures the deactivate various other coronaviruses.

A 2020 review approximates that the adhering to temperatures and also exposure times may be enough to deactivate SARS-CoV-2, based upon information around the older virus SARS-CoV:

above <167°F> (75°C) because that 3 minutes (The first value is a correction of a typographical error in the review.)above 149°F (65°C) because that 5 minutesabove 140°F (60°C) for 20 minutes

However, as these experiment took ar in highly regulated laboratories, they execute not necessarily reflect how efficient heat is at killing the novel coronavirus in more everyday settings, such together hospitals or a person’s home.

Researchers think SARS-CoV-2 mostly spreads through respiratory droplets, which space droplets that enter the air as soon as a human coughs, sneezes, or talks. Heat is only helpful for sterilization when these droplets soil on things or surface.

Even then, it may not be possible to usage temperatures high enough to kill SARS-CoV-2 in the home, as many appliances and also faucets cannot carry out water hot sufficient to deactivate the virus.

For this reason, the is best to monitor the advice the the Centers for condition Control and Prevention (CDC), which introduce cleaning with soaps, detergents, or disinfectants.


Do high temperatures kill the virus in food?

According come the CDC, the risk of contracting SARS‐CoV‐2 indigenous food assets or packaging is an extremely low. The key route the transmission appears to be v droplets in the air.

It is feasible for who to develop COVID-19 after touching food that contains SARS-CoV-2 and then emotional their eyes, mouth, or nose. However, despite the possibility, there room no current cases of COVID-19 that doctors have the right to attribute to contact with contaminated food.

Nevertheless, the is always a an excellent idea to chef food in ~ the encourage temperature to protect against foodborne illnesses. A 2020 evaluation notes the exposure come normal cooking temperatures will kill viruses in food, consisting of SARS-CoV-2.

Other things human being can perform to gain food for sure include:

cooking foods items until they space thoroughly cooked follow to the packet instructionsusing separate utensils and plates from family members members that may have COVID-19

Most washing devices do no reach temperatures high sufficient to kill SARS-CoV-2. Devices that deserve to reach temperature of 158°F (70°C) or over for 5 minutes may be able to do that, however research has not evidenced this.

Similarly, warm water indigenous a faucet will certainly not it is in hot sufficient to kill the novel coronavirus. In the joined States, water indigenous a faucet can not reach above 120°F (49°C).

The CDC proposal laundering garments at the warmest possible temperature and then enabling them to dry fully to mitigate the danger of transmission.

People must also:

regularly disinfect laundry baskets and clothes hampersdry laundry far from human being who may have actually COVID-19wash the hands extensively after managing unwashed or wet laundry

It is safe to wash laundry from who who has actually COVID-19 in addition to laundry from other people. However, the human doing the laundry should wear a challenge mask and also protective gloves, particularly when dealing with unwashed clothing, bedding, or towels indigenous the human being with the virus.


In some cases, it is not safe to rely on heat for protection versus SARS-CoV-2. This may be due to the fact that the heat source cannot acquire hot sufficient for long sufficient or because exposure to together high temperatures would certainly be dangerous.

The adhering to sources perform not provide enough warmth to death SARS-CoV-2:

hot drink waterhot bathshair dryerswarm or warm weathersaunas and vapor rooms

People have to not use warm to kill SARS-CoV-2 on or inside the body. The temperatures that death SARS-CoV-2 space unsafe because that humans and also animals and will reason burns.

Even if an individual has a fever, coronaviruses continue to be alive at these body temperatures.

However, world can use proper soaps and cleansers externally ~ above the skin to eliminate viruses.


Cleaning and also disinfecting objects, surfaces, and clothing helps prevent the spread out of SARS-CoV-2. Other ways to prevent transmission in the house include:

regularly cleaning frequently touched electronic devices, such as phones and also tabletsregularly cleaning high-touch surfaces, such as door handles, light switches, and dining tablescleaning any type of surfaces that room visibly dirtywashing home furnishings, such as cushions, blankets, and also drapestaking extra precautions if who in the home has COVID-19, such together wearing gloves and also a challenge mask once cleaning or entering their room, making use of disinfectants come sterilize surfaces and objects, and also keeping your trash separated and also in a sealed bag

Use commodities that are perfect for each surface and also follow the accuse on the label.

Other essential precautions come take against COVID-19 include:

Physical distancing: within the home, avoid close call with world who have actually COVID-19. External of the home, remain 6 feet far from those who space not family members members. This street is about two eight lengths.Wearing a face mask: everyone who has not received the vaccine, who is 2 years old or older, and also who go not have a conflicting medical condition should wear a confront mask in indoor settings external of the home. It is not necessary to undertake a mask outdoors uneven someone is in one area v a high variety of COVID-19 cases, or if physics distancing the end is no possible.Avoiding poorly ventilated spaces and crowds: as soon as indoors, open up windows and doors to permit in new air. As much as possible, avoid public indoor areas that do not have a source of new air. Gift in crowded indoor areas, such as movie theaters and bars, rises the risk of transmission.Washing the hands often: use soap and water to wash the hands for 20 seconds, an especially after coughing, sneezing, blow the nose, or being in a public place.

Evidence argues that SARS-CoV-2 becomes deactivated in ~ a temperature of 158°F (70°C) after 5 minute of exposure.

However, although high temperatures can sterilize objects the may have actually come into contact with SARS‐CoV‐2, this way killing the virus is not constantly reliable, achievable, or safe to shot at home.

Using heat water and also an suitable soap or detergent can successfully clean surfaces and objects that may have come into contact with the novel coronavirus.

People can additionally use hand soaps and alcohol gelatin to clean their hands, and normal cooking temperatures to ensure their food is safe.
