Many UK healthcare workers may have had coronavirus without knowing it – new survey of smell loss

Lack of odor is a recognised symptom of COVID-19 within the UK. Nevertheless, it was solely added to the official listing of signs on Might 18, a full month after the World Well being Group recognised it as a symptom. Earlier than this time, any member of NHS workers reporting a lack of odor – particularly within the absence of different signs – wouldn’t have been suggested to self-isolate.

Because the pandemic hit its peak in April, over 3,000 individuals had been being admitted to UK hospitals a day. This meant many NHS workers had been in danger, and given a few of the issues that had been confronted with PPE (private protecting tools), those that did develop signs wanted to self-isolate.

Survey of NHS workers

In April and Might 2020, on the top of the pandemic, we performed a survey of hospital workers to learn how a lot of them had been affected by odor loss. And of those that had skilled odor loss, we wished to know what number of had it as an remoted symptom or earlier than different signs appeared.

The survey was distributed to workers at hospitals in London, Norfolk and Larger Manchester. A complete of 1,041 healthcare employees took half. Over half of the respondents had been beneath the age of 40, and greater than two-thirds had been girls.

The preliminary outcomes of our research had been revealed in The Lancet Microbe.

We discovered that almost two-thirds of workers reported a sudden lack of their sense of odor or style, or each, and that these affected had been eight occasions extra more likely to have a optimistic check for COVID throughout the identical interval (April-Might) than these with out odor loss.

4 weeks after dropping their sense of odor, solely half the hospital workers surveyed had totally recovered it. A stark discovering was that over half of those that misplaced their sense of odor continued to work, and lots of of these individuals had been most likely extremely contagious on the time.

In practically one in 5 circumstances, lack of odor was reported as the one symptom. And in a single in three of these circumstances, it occurred earlier than different signs appeared.

Scent distortions and burning or tingling within the nostril and mouth had been additionally skilled by one in three of these affected. Solely 40% reported a cough or fever, which had been the preliminary official signs that everybody was instructed to look out for.

The opposite key discovering was that 98% of the survey respondents reported that their signs had been gentle to average, in order that they had been extra more likely to proceed with their day by day actions.

Being extra conscious of signs is essential in order that when recognised, these experiencing them self-isolate. That is notably vital for healthcare employees with a view to scale back the unfold in hospitals.

What number of infections had been preventable?

We will by no means know the true variety of healthcare employees who skilled odor loss and didn’t isolate that handed the virus to their co-workers or to different sufferers. But when practically half of them continued to work, then we would estimate that over 5,000 healthcare employees per day had been transmitting the virus in hospitals and to their households. We will solely surprise at what number of infections had been preventable had these NHS workers members been warned about odor loss.

However this lesson applies to all of us. Because the variety of individuals affected by COVID will increase and the knowledge on patterns of signs will increase, we should proceed to remain alert to those symptom patterns and take applicable motion in order that the virus might be contained till a secure, efficient vaccine turns into accessible.

Scent loss has been a symptom that has lengthy been uncared for because of being considered unimportant. Hopefully, now it is going to be held with higher significance.

Whereas 85% of these affected by odor loss had been solely with out it for 2 to a few weeks, an estimated 20,000 are nonetheless affected and including to the 5% of the inhabitants for whom complete odor loss is a day by day reality of life.
