Can coronavirus live on paper mail
The short answer is: it's possible, but unlikely.
Coronavirus, including SARS-CoV-2, can survive on surfaces for a short period of time. However, the likelihood of it surviving on paper mail depends on several factors:
- Type of paper: The type of paper used for mail can affect the virus's survival. For example, paper with a glossy finish or coated with a chemical treatment may reduce the virus's ability to survive.
- Handling and storage: If the mail is handled and stored properly, the risk of transmission is lower. For example, if the mail is sealed in an envelope and not touched or handled excessively, the virus may not survive.
- Environmental conditions: Temperature, humidity, and exposure to light can all impact the virus's survival. For example, if the mail is exposed to high temperatures (above 140°F/60°C) or low humidity, the virus may not survive.
- Duration of exposure: The longer the virus is exposed to the paper, the higher the risk of transmission.
Studies have shown that:
- SARS-CoV-2 can survive on paper for up to 24 hours at room temperature (around 72°F/22°C) and humidity levels around 50%.
- The virus can survive for up to 7 days on paper at refrigerated temperatures (around 40°F/4°C) and humidity levels around 50%.
- The virus is unlikely to survive on paper for more than 3 days at temperatures above 140°F (60°C) or below -20°F (-29°C).
To minimize the risk of transmission through paper mail:
- Wash your hands thoroughly after handling mail.
- Avoid touching your face, eyes, or mouth after handling mail.
- Disinfect your hands and any surfaces that may have come into contact with the mail.
- Consider using gloves when handling mail, especially if you're handling mail from an unknown or potentially contaminated source.
It's important to note that the risk of transmission through paper mail is generally low, and the virus is more likely to be transmitted through close contact with an infected person or contaminated surfaces.
