A study of severe COVID-19 in the United Kingdom reveals the risk that healthcare workers take to help others.

A new study in the journal Occupational & Environmental Medicine examines the risks that essential and nonessential British workers will develop severe COVID-19.

It suggests that healthcare workers are seven times more likely to develop severe cases of COVID-19 than people with nonessential roles.

Although it makes sense that people who interact with COVID-19 patients are at greater risk, this is the first study to compare their risk of developing severe disease with that of other types of workers.

As the study authors conclude:

Our findings reinforce the need for adequate health and safety arrangements and provision of [personal protective equipment] for essential workers, especially in the health and social care sectors. The health and well-being of essential workers is critical to limiting the spread and managing the burden of global pandemics.

The researchers analyzed three sources of data:

The UK Biobank data allowed the researchers to track multiple factors that may be associated with the development of severe disease beyond ones occupation.

A total of 120,075 employees, aged 4964 years, were involved in the study. Black and Asian people, who are more likely to be essential workers, comprised nearly 3% of the group.

Around 32,127 employees, or 29% of the participants, were essential workers.

The team broke the healthcare workers category down further into:

For the purposes of the study, the researchers considered anyone with a hospital diagnosis of COVID-19 and anyone who died of the disease to have a severe case.

Of the total study group, 271 employees had severe COVID-19.

The healthcare workers category overall experienced an average of seven times as many severe cases as nonessential workers.

The study suggests that medical support staff are the most vulnerable. They were nine times more likely to develop severe disease than people in nonessential occupations.

People in the social care and education category had an 84% higher risk, while those providing social care were 2.5 times more likely to have a severe case of the disease.

Transport workers were twice as likely to get seriously ill as nonessential workers, and the risks for people in the other category, in general, were 60% higher.

The researchers analysis revealed a racial disparity in the likelihood of having a severe case of the disease. This parallels the racial imbalance in deaths from COVID-19.

Black and Asian essential workers were eight times as likely to have severe cases as white nonessential workers.

Black and Asian nonessential employees were three times more likely to have severe cases than their white counterparts.

In addition, their severe case rates were roughly equivalent to those that white essential workers experienced.

The researchers point out several limitations of their study. These include the following:

However, the study authors do point out that despite these issues, their conclusions are consistent with the findings of other COVID-19 research.
