Scientists coronavirus can stay in air for hours on surfaces for days
You're referring to the recent studies on the persistence of SARS-CoV-2, the virus that causes COVID-19.
Yes, several studies have shown that SARS-CoV-2 can remain viable on surfaces and in the air for extended periods of time. Here are some key findings:
Airborne transmission:
- A study published in the New England Journal of Medicine found that SARS-CoV-2 can remain airborne for up to 3 hours.
- Another study published in the journal Nature Medicine found that the virus can remain airborne for up to 4 hours.
- The World Health Organization (WHO) has stated that SARS-CoV-2 can remain airborne for up to 2 hours.
Surface transmission:
- A study published in the Journal of Hospital Infection found that SARS-CoV-2 can remain viable on surfaces for up to 9 days.
- Another study published in the journal Emerging Infectious Diseases found that the virus can remain viable on surfaces for up to 14 days.
- The Centers for Disease Control and Prevention (CDC) has stated that SARS-CoV-2 can remain viable on surfaces for up to 7 days.
It's important to note that the exact duration of time that SARS-CoV-2 can remain airborne or on surfaces may vary depending on factors such as:
- Environmental conditions (e.g., temperature, humidity)
- Surface type and material
- Presence of other substances or contaminants
- Handling and cleaning procedures
These findings highlight the importance of taking precautions to prevent the spread of COVID-19, such as:
- Wearing masks and practicing social distancing
- Frequently washing hands with soap and water
- Cleaning and disinfecting surfaces regularly
- Improving ventilation in indoor spaces
Remember, it's always better to err on the side of caution when it comes to preventing the spread of infectious diseases.
