Sažetak
Backgrounds: Non-pharmacological measures (NPMs) introduced to prevent the spread of SARS-CoV-2 affected the incidence of respiratory viruses, but not with the same effect on all types of respiratory viruses. The aim of our research was to compare the incidence of enveloped versus naked respiratory viruses before and during NPMs in Croatia. Methods: In four years period (5/2017-3/2021), specimens obtained from 957 children up to 18 years of age which were hospitalized due to respiratory infection were collected and tested for fifteen respiratory viruses using multiplex PCR. Results: One or more respiratory viruses were detected in 739 (77.2%) patients, of which one virus in 496 (67.1%) and two or more viruses in 243 (32.8%) cases. The most frequently detected was rhinovirus (343 ; 35.8%), followed by: respiratory syncytial virus type A and B (162 ; 16.9%), adenovirus (145 ; 15.2%), parainfluenza viruses types 1-4 (101 ; 10.6%), bocavirus (73 ; 7.6%), influenza viruses type A and B (69 ; 7.2%), enterovirus (61 ; 6.4%), coronaviruses OC43 and 229E/NL63 (54 ; 5.6%) and metapneumovirus (30 ; 3.1%). Incidence of all tested viruses did not differ between seasons 2017/18, 2018/19 and 2019/20, while significantly dropped in 2020/21 when NPMs were in use (P<0.05). However, while the incidence of enveloped viruses (i.e., respiratory syncytial virus, influenza and parainfluenza viruses, seasonal coronaviruses, metapneumovirus) was practically zero, the non-enveloped viruses (i.e., rhinovirus, bocavirus, adenovirus and enterovirus) showed activity of quarter of the value compared to previous seasons despite NPMs. Conclusions/Learning points: The spread of enveloped respiratory viruses is effectively prevented with NPMs. To completely prevent the spread of non-enveloped respiratory viruses, NPMs such as distance and wearing masks are not sufficient, specific pharmacological measures should be developed and considered.
