[h=3]Abstract[/h] [h=4]BACKGROUND:[/h] Data on the seasonality of respiratory viruses helps to ensure that vaccinations can be timed optimally and that possible variant outbreaks can be monitored.
[h=4]OBJECTIVES:[/h] We designed our study to describe the molecular epidemiology and seasonality of acute respiratory infection (ARI)-related respiratory viruses in the United Arab Emirates (UAE).
[h=4]METHODS:[/h] We collected both upper and lower respiratory specimens for analysis from all patients who visited the Sheikh Khalifa Specialty Hospital (SKSH) with ARI for over 2 years. The multiplex real-time reverse transcription PCR (rRT-PCR) test was used to detect respiratory viruses such as human adenovirus, influenza virus (FLU) A and B, respiratory syncytial virus, parainfluenza viruses, human rhinovirus, human metapneumovirus, human enterovirus, human coronavirus, and human bocavirus.
[h=4]RESULTS:[/h] We collected 1362 respiratory samples from 733 (53.8%) male and 629 (46.2%) female ARI patients who visited the SKSH between November 2015 and February 2018. The rRT-PCR test revealed an overall positivity rate of 37.2% (507/1362). The positive rate increased during winter; it was highest in December and lowest in September. FLU was the most frequently detected virus (273/1362 [20.0%]), followed by human rhinovirus (146/1362 [10.7%]). The FLU positivity rate showed two peaks, which occurred in August and December. The peak-to-low ratio for FLU was 2.26 (95% confidence interval [CI]: 1.52-3.35).
[h=4]CONCLUSIONS:[/h] The pattern of FLU in the UAE parallels to that of temperate countries. The trend of small peak of FLU in the summer suggests that a semi-seasonal pattern is possible in the UAE. This article is protected by copyright. All rights reserved.
