| Sumario: | Introduction: The main human Coronavirus (HCoVs) involved in human respiratory tract infections are the 229E, NL63, and OC43.
Due to the lack of information about these infections in our country, it seemed important to know its impact on acute respiratory disease.
Material and Methods: In the period February-April 2014, we have studied the presence of different respiratory viruses in 950 samples (throat swabs and/or nasopharyngeal aspirates) belonging to 674 (70.9%) children (<15 years) and 276 adults (29.1%).
The detection of respiratory viruses was performed using commercial automatic real-time PCR system (Anyplex RV16), detecting 16 different viruses.
Results: The overall HCoV detected was 4.6% of all samples studied and 7.8% (44 cases) of the positive samples. The 44 HCoVs detected corresponded to 20 HCoV-OC43 (45.4%), 17 HCoV-NL63 (38.6%) and 7 HCoV-229E (15.9%). The HCoVs alone were
detected in 25 cases (56.8%) and with other respiratory viruses in 19 (43.2%) cases (coinfections). In the mixed infections, rhinovirus was detected in 11 cases (57.8%), influenzavirus type B in 6 cases (31.5%), adenovirus in 1 case and RSV-A in 1 case. HCoVs were detected in the 26 children (59%) and 18 adults (41%). Of the 44 cases, 13 (29.5%) required hospital admission, No patients infected by HCoVs died as a direct result of respiratory tract infection.
Conclusions: This study demonstrates the importance of respiratory infections caused by HCoVs, especially in children |
