Can the coronavirus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.

How long can COVID-19 survive out in the air and on other surfaces?
The scientists found that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was detectable in aerosols for up to three hours, up to four hours on copper, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel.
How long can COVID-19 stay airborne?
Transmission of COVID-19 from inhalation of virus in the air can occur at distances greater than six feet. Particles from an infected person can move throughout an entire room or indoor space. The particles can also linger in the air after a person has left the room – they can remain airborne for hours in some cases.
What temperature kills the virus that causes COVID-19?
Research on the impact of temperature has shown that SARS-CoV-2, the virus that causes COVID-19, is sensitive to elevated temperatures, with over 99.99% inactivation in only a few minutes at 70°C (158°F). However, this temperature is far outside the limits of human comfort and could damage some building materials.
How long have coronaviruses existed?
The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.
In what conditions does COVID-19 survive the longest?
Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).
Can you get COVID-19 from touching infected surfaces or objects?
It may be possible that a person can get COVID-19 by touching a surface or object that has the virus on it and then touching their own mouth, nose, or possibly their eyes. This is not thought to be the main way the virus spreads, but we are still learning more about this virus.
What is COVID-19 airborne transmission?
Airborne means a virus can be transmitted from person to person by the tiny particles of moisture released from the mouth or nose when speaking, breathing or singing. These droplets are suspended in the air over long periods of time.
Can COVID-19 be spread through breathing?
Infection control guidelines have stated that most respiratory virus transmission occurs from large infected droplets produced by coughing, sneezing, and breathing in close proximity to another person.
How is airborne transmission of COVID-19 different from droplet transmission?
Airborne transmission is different from droplet transmission as it refers to the presence of microbes within droplet nuclei, which are generally considered to be particles <5μm in diameter, can remain in the air for long periods of time and be transmitted to others over distances greater than 1 m.In the context of COVID-19, airborne transmission may be possible in specific circumstances and settings in which procedures or support treatments that generate aerosols are performed;

Can COVID-19 be destroyed by freezing it in food?
It is unlikely that freezing by itself would be effective in inactivating COVID-19, however as detailed by the FDA, there is currently no evidence of food or food packaging being associated with transmission of COVID-19.
Can the coronavirus survive in a swimming pool?
The CDC states that it’s unlikely that the new coronavirus can survive in a pool that’s properly maintained — which includes regularly checking and adjusting the pool’s chlorine levels and pH.In addition, the CDC also reports that there’s currently no evidence that COVID-19 is spread through water in a pool or hot tub

Can the coronavirus disease spread through pools and hot tubs?
See full answer
There is no evidence that the virus that causes COVID-19 can be spread to people through the water in pools, hot tubs, spas, or water play areas. Proper operation and maintenance (including disinfection with chlorine and bromine) of these facilities should inactivate the virus in the water.While there is ongoing community spread of COVID-19 of the virus that causes COVID-19, it is important for individuals as well as owners and operators of these facilities to take steps to ensure health and safety:Everyone should follow local and state guidance that may determine when and how recreational water facilities may operate.Individuals should continue to protect themselves and others at recreational water venues both in and out of the water – for example, by practicing social distancing and good hand hygiene.
