How Long Does COVID Stay on Surfaces?
Understanding how long the novel coronavirus, SARS-CoV-2, can survive on various surfaces is crucial for preventing its transmission. This article delves into the details, providing you with a comprehensive overview of the duration of COVID-19 on different types of surfaces.
Survival Duration on Various Surfaces
Research indicates that the survival time of COVID-19 on surfaces can vary significantly. Here’s a breakdown of the duration on different types of surfaces:
| Surface Type | Survival Duration (Days) |
|---|---|
| Steel | Up to 72 hours |
| Plastic | Up to 72 hours |
| Cardboard | Up to 24 hours |
| Wood | Up to 72 hours |
| Aluminum | Up to 72 hours |
| Gold | Up to 72 hours |
| Brass | Up to 72 hours |
| Stainless Steel | Up to 72 hours |
| Gold | Up to 72 hours |
| Brass | Up to 72 hours |
| Stainless Steel | Up to 72 hours |
It’s important to note that these durations are estimates and can vary depending on factors such as temperature, humidity, and the presence of disinfectants.
Survival Duration in Air
In addition to surfaces, the survival time of COVID-19 in the air is also a concern. Studies have shown that the virus can remain suspended in the air for varying periods, depending on the environment.
One study found that the virus could remain viable in the air for up to 3 hours in a well-ventilated room. However, in poorly ventilated areas, the survival time could be extended to up to 17 hours.
Transmission Through Surfaces
While the survival time of COVID-19 on surfaces is relatively short, it’s still possible for transmission to occur. The virus can be transmitted when a person touches a contaminated surface and then touches their face, particularly their mouth, nose, or eyes.
It’s important to practice good hygiene, such as washing your hands frequently with soap and water for at least 20 seconds, to minimize the risk of transmission.
Disinfection and Cleaning
Regular cleaning and disinfection of surfaces can help reduce the risk of COVID-19 transmission. Here are some tips for effective cleaning and disinfection:
- Use a household disinfectant that is effective against viruses, such as a mixture of bleach and water or a commercial disinfectant with an EPA registration number.
- Follow the manufacturer’s instructions for proper use and dilution.
- Wear gloves and a mask while cleaning and disinfecting to protect yourself.
- Focus on high-touch surfaces, such as doorknobs, light switches, and countertops.
- Allow the surface to air dry after cleaning and disinfection.
Conclusion
Understanding how long COVID-19 can survive on surfaces is essential for preventing its transmission. By practicing good hygiene, regularly cleaning and disinfecting surfaces, and staying informed about the latest research, you can help protect yourself and others from the virus.
