Search Strategy and Selection Criteria
Following PRISMA guidelines, a systematic online search of English and Indonesian language databases were conducted. For the English journals, a search of three scientific abstract indexing databases (PubMed, Web of Science, and CAB Abstracts), with no restriction on the year of publication, was performed on 23 February 2021 using the following structured search query ((virus or viruses or viral) AND (respiratory) AND (Indonesia)).
For the Indonesian language journals, a search of the Garuda database, with no restriction on the year of publication, was performed on 03 February 2021. Garuda is a comprehensive database operated by the Indonesian Ministry of Research, Technology and Higher Education, which contains various national publications from all universities in Indonesia. Given that the database lacked the functionality to use a multi-string structured search query, the single term “virus” was instead used. Thereafter, a manual review and selection strategy was performed based on the inclusion and exclusion criteria.
