Abstract

The COVID-19 pandemic initially started in China then spread to Europe. It is not known whether COVID-19 affects patients differently across the two continents. We aimed to describe our cohort of patients admitted to a single British centre with COVID-19 in comparison to a Chinese cohort of similar size and admitted over a similar time period to Chinese centres. We present a comparison of 62 Chinese and 71 British cases hospitalised for COVID-19. Cases in both sites were confirmed by a positive RT-PCR of nasopharyngeal swabs. Comparison analysis highlighted some differences between both populations. The most striking difference is the significantly older age of the British population (72% of the British ≥ 66 years compared to only 3% of the Chinese patients, difference of 69%, 95% confidence interval (CI) 68.3% to 69.7%, respectively) and the associated significant premorbid conditions (85% of patients vs 32%, difference of 53%, 95% CI 52 to 54%, respectively). Gastrointestinal and general symptoms were more common clinical presentation in the British while respiratory symptoms were more prominent in the Chinese cohort. Mortality was significantly higher in the British cohort 14% compared to none in the Chinese cohort (difference of 14%, 95% CI 13.7 to 14.3%). We conclude that COVID-19 does present differently in these two cohorts, but the apparent differences in the clinical presentations could be explained by the inherent differences in the demographics and case mix…

How strong is the evidence?

Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 19 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
