Is It Safe To Lick An Envelope

Is It Safe To Lick An Envelope

One of the most important parts of this issue is that the main way the virus spreads is through person-to-person contact.

Inanimate surfaces play a very small part in transmission of COVID (Dr John Segreti, Medical Director of Infection Control & Prevention, Rush University Medical Centre).
This leading to the fact that the virus can survive on different surfaces for varying amounts of time; for paper and tissue paper the virus is said to have lost infectivity within 3 hours (Professor Mark Harris, School of Molecular & Cellular Biology, University of Leeds).

As such one suggested piece of advise to ease any concern would be to leave the paper envelope untouched for a few hours before licking to seal, this way you can be assured that risk is minimal.



Whilst as the recipient of the envelope, it is advisable to again leave the envelope for a few hours once delivery has occurred to ensure that any virus particles do not survive, resulting in the envelope being safe to open. (Professor Mark Harris, School of Molecular & Cellular Biology, University of Leeds).


As is the case with touching any object or surface, to minimise risk or concern, ensure that good hand hygiene is maintained, by washing hands after picking something up or touching a frequently used surface (Professor Sally Bloomfield, London School of Hygiene & Tropical Medicine).


Alternatively, many consumers have begun using different methods and tools to seal gummed envelopes. One technique being to use a moist sponge to activate the sealing gum; the same effect would occur using a wet cotton bud.


However, this cannot guarantee no risk. One alternative that has seen huge increase in demand since the start of the pandemic is the use of ‘Peel & Seal’ envelopes to minimise contact with the envelope.
