Healthcare workers who pick their noses are more likely to get Covid and should be made aware of the infection risk, a study suggests.

Of 219 participants, 17% of those who admitted nose-picking tested positive for Covid compared to 6% of those who did not pick their noses.

The Dutch researchers said the role of nose-picking in spreading the virus could be underestimated.

Men and younger people were more likely to admit to the habit, they found.

The survey of healthcare workers at two university medical centres in The Netherlands in 2020 revealed the majority (85%) of respondents admitted to picking their nose “at least incidentally” – somewhere between monthly, weekly and daily.

And doctors were the most frequent nose-pickers (95%), followed by support staff (86%) and nurses (80%), the data showed.

In contrast, a third of staff admitted to biting their nails. Nail-biting, having a beard or wearing glasses did not make any difference to the likelihood of testing positive, the study found.

Moist tissues

The researchers said as the nose was a main route for coronavirus to get into the body, nose-picking may make infection easier by directly introducing virus particles on the hands into the nose.

The habit could also mean the virus spreading more easily to other people.

Even before symptoms start developing, they explained there would be a lot of virus in the moist tissues that line the nose in the days after becoming infected.

“Subsequently, nose picking healthcare workers who are infected with [coronavirus] could contaminate the work environment, potentially leading to further transmission,” they concluded.

The study authors pointed to the fact that coronavirus transmission between staff was an important problem in hospitals, saying the role of nose picking could be “underestimated”.

Writing in the PLOS One journal, they recommended “educational sessions against nose-picking in infection prevention guidelines”.
