Abstract
Objectives: This study aimed to investigate the trends in hospital admissions due to viral infections characterized by skin and mucous membrane lesions in England and Wales between 1999 and 2019. Methods: This is an ecological study using publicly available databases in England and Wales; the Hospital Episode Statistics database in England and the Patient Episode Database for Wales. Hospital admissions data were collected for the period between April 1999 and March 2019. Hospital admissions due to viral infections characterized by skin and mucous membrane lesions were identified using the tenth version of the International Statistical Classification of Diseases system, diagnostic codes B00–B09. The trend in hospital admissions was assessed using a Poisson model. Results: Hospital admissions for different causes increased by 51.9% (from 25.67 (95% CI 25.23–26.10) in 1999 to 38.98 (95% CI 38.48–39.48) in 2019 per 100,000 persons, trend test, p < 0.01). The most prevalent viral infections characterized by skin and mucous membrane lesions hospital admissions causes were zoster (herpes zoster), varicella (chickenpox), herpesviral (herpes simplex) infections, and viral warts, which accounted for 26.9%, 23.4%, 18.7%, and 17.6%, respectively. The age group below 15 years accounted for 43.2% of the total number of admissions. Females contributed to 50.5% of the total number of admissions. Hospital admission rate in males increased by 61.1% (from 25.21 (95% CI 24.59–25.82) in 1999 to 40.60 (95% CI 39.87–41.32) in 2019 per 100,000 persons). The increase in females was 43.2% (from 26.11 (95% CI 25.49–26.72) in 1999 to 37.40 (95% CI 36.70–38.09) in 2019 per 100,000 persons). Conclusion: Our study demonstrates an evident variation in hospital admission of viral infections characterized by skin and mucous membrane lesions based on age and gender. Efforts should be directed towards vaccinating high-risk groups, particularly the elderly and females. Moreover, efforts should be focused on vaccinating the young population against varicella, particularly females who are more susceptible to acquiring the infection. Further observational and epidemiological studies are needed to identify other factors associated with increased hospital admission rates.

The total annual number of hospital admissions for different causes increased by 73.1% from 13,383 in 1999 to 23,169 in 2019, representing an increase in hospital admission rate of 51.9% (from 25.67 in 1999 to 38.98 in 2019 per 100,000 persons, trend test, p < 0.01)

Summary
A virus is a microscopic organism that cannot live outside the host body [1]. It is composed of either ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) as genetic material [1]. Infectious diseases are a major cause of morbidity and mortality worldwide [2]. Viruses cause a wide range of infectious diseases and are a major concern for public health. Infections due to viruses are responsible for millions of deaths worldwide [1]. Some viral infections are chronic in nature and are associated with poor health outcomes and significant morbidities, such as infections due to human immunodeficiency virus (HIV) and hepatitis viruses [1]
