We conducted a\u00a0 descriptive study based on the detection records of\u00a0 adenovirus, influenza A and B (IA and IB), parainfluenza\u00a0 1-3 (PIV), metapneumovirus (hMPV), and respiratory\u00a0 syncytial virus (RSV). Of 1740 episodes (1220 patients),\u00a0 14.4% tested positive: 196 (78.0%) RSV, 23 (9.2%) IA, 14\u00a0 (5.6%) PIV-3, and 13 (5.2%) hMPV. In children under five\u00a0 years of age, RSV predominated, while in children over\u00a0 five years of age, it was IA. The frequency of ARI was\u00a0 lower with increasing age, during the pandemic (2020- 2021), and the spring and summer seasons. The higher\u00a0 frequency of respiratory viruses in 2022 highlights the\u00a0 need to maintain and strengthen surveillance and\u00a0 preparedness against these outbreaks.<\/jats:p>","DOI":"10.17843\/rpmesp.2026.433.15564","type":"journal-article","created":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T21:12:11Z","timestamp":1791234731000},"page":"349-55","source":"Crossref","is-referenced-by-count":0,"title":["Infecciones respiratorias virales agudas en ni\u00f1os antes y durante la pandemia de COVID-19 en un hospital de referencia peruano","Acute viral respiratory infections in children before and during the COVID-19 pandemic in a Peruvian reference hospital"],"prefix":"10.17843","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9846-8503","authenticated-orcid":false,"given":"Jhonatan R.","family":"Mejia","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9441-1067","authenticated-orcid":false,"given":"Daniel","family":"Fernandez-Guzman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3351-7877","authenticated-orcid":false,"given":"Medalit","family":"Luna-Vilchez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8758-0463","authenticated-orcid":false,"given":"Alvaro","family":"Taype-Rondan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"7920","published-online":{"date-parts":[[2026,9,4]]},"container-title":["Revista Peruana de Medicina Experimental y Salud P\u00fablica"],"original-title":[],"link":[{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/15564\/6301","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/15564\/6305","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/download\/15564\/6301","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,5]],"date-time":"2026-10-05T21:12:16Z","timestamp":1791234736000},"score":1,"resource":{"primary":{"URL":"https:\/\/rpmesp.ins.gob.pe\/index.php\/rpmesp\/article\/view\/15564"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.17843\/rpmesp.2026.433.15564","relation":{},"ISSN":["1726-4642","1726-4634"],"issn-type":[{"value":"1726-4642","type":"electronic"},{"value":"1726-4634","type":"print"}],"subject":[],"published":{"date-parts":[[2026,9,4]]}}}
