People With Rare Diseases Have Higher Recorded COVID-19 Rates: UK Study Based On 62.5 Million People

People With Rare Diseases Had Higher Recorded COVID-19 Rates: UK Study Based On 62.5 Million People

Individuals diagnosed with <span>rare diseases</span> had higher COVID-19 rates than people who did not have them. As per a study analysing health records of 62.5 million people in England, there were significant differences in infections recorded across ethnic groups and individual rare diseases.

Published in <em><span rel="noindex">Scientific Reports</span></em> recently, the study analysed 406 rare diseases with the help of healthcare records from the <span>National Health Service</span> (NHS) in England.

Of the 62.5 million people included in the analysis, around 1.05 million, or 1.7%, had at least one of the 406 rare diseases.

COVID-19 infections were reported in around 32.8% of people with a rare disease, compared with 29% of those without one. Even though the difference between the two figures is not far from each other, it makes us stop and think.

According to the study researchers, the findings provide a country-wide picture of rare disease rates and incidence of COVID-19 infections across various ethnic groups.

<h2>COVID-19 Infection Rates Differed Across Rare Diseases</h2>

The study found that COVID-19 infection rates differed significantly depending on the rare disease. Among the 25 most common rare diseases, infection rates ranged from 24.6% to 41.2%.

Four conditions had recorded infection rates below 30%: <span>congenital laryngomalacia</span>, at 24.6%; <span><a href="https://www.healthandme.com/health/retinopathy">retinopathy</a></span> of prematurity, at 26.5%; <span>polymyalgia rheumatica</span>, at 27.1%; and infantile apnoea, at 29.9%. The remaining 21 conditions had recorded infection rates between 30% and 50%.

These differences highlight an important point that people with rare diseases should not be treated as one uniform group, especially when it comes to their COVID experience.

However, the study did not establish that every person with a <a href="https://www.healthandme.com/health-news/cladophialophora-bantiana-us-cdc-flags-surge-in-deadly-brain-fungus-cases-article-156286674" data-type="tilCustomLink">rare disease</a> had a higher risk of contracting the virus, nor did it show that rare diseases necessarily led to more severe COVID-19.

<h2>Infection Rates Differed By Ethnicity</h2>

The researchers also identified differences in <a href="https://www.healthandme.com/health-wellness/flu-covid-rsv-shingles-vaccines-studies-link-all-4-to-better-heart-health-article-156364268" data-type="tilCustomLink">COVID-19 </a> infection rates among ethnic groups within the rare disease occurrence.

The highest rates were observed among people classified as White British, at 33.7%, and those in the broader White category used by the Office for National Statistics (ONS), at 33.5%.

Lower rates were recorded among several other groups, including Black African people, at 23.8%; Gypsy or Irish Traveller people, at 24.1%; Bangladeshi people, at 27.2%; and Pakistani people, at 27.7%.

The researchers said that this pattern was different from trends in the general population, where ethnic minority groups experienced an uneven burden of COVID-19.

<h2>Rare Diseases Varied Across Ethnic Groups</h2>

Apart from COVID-19 infection, the study mapped 406 rare diseases across various ethnic groups. The researchers found variations in how frequently each condition was recorded.

Some of these differences became clearer when broad ethnic categories were divided into more specific groups. For example, discoid lupus erythematosus was more prevalent among Black Caribbean people than among Black African people.

The researchers also found that <a href="https://www.healthandme.com/health-wellness/rare-canine-tooth-found-in-indian-teens-eyelid-what-is-an-ectopic-tooth-article-156353126" data-type="tilCustomLink">polymyalgia rheumatica</a> was more prevalent among White people than Asian or Asian British and Black or Black British populations.

The researchers carried out a cross-sectional analysis using NHS England’s Secure Data Environment, linking primary care, hospital and mortality records for people alive on July 31, 2023.

They estimated the prevalence of 406 rare diseases and examined COVID-19 infections across the overall population, individual rare diseases and ethnic groups. The analysis used both six ONS ethnic categories and 19 more detailed NHS ethnicity classifications.

The study’s large population base allowed the researchers to examine conditions that can be difficult to investigate because each rare disease affects relatively few people.

The researchers said the national estimates provide a baseline for understanding rare disease rates and COVID-19 cases across different populations in England. The findings may help inform future research and support efforts towards earlier diagnosis and better healthcare.
