Objective To evaluate the prevalent epidemics of major respiratory viral infectious diseases in neighboring countries of the South China Sea such as Vietnam, Malaysia and Philippines from 2007 to 2019. Methods We performed a systematic literature search for articles on respiratory viral infectious diseases from PubMed, Web of Science, Embase, Medline, Scopus and Google scholar published from January 2015 to June 2020. Studies reporting data on the prevalence and the epidemic situation of respiratory viral infectious diseases were selected for analysis. Methodological quality of the studies was assessed using AHRQ (The Agency for Healthcare Research and Quality) and NOS (The Newcastle-Ottawa Scale) criteria. Results A total of 38 observational studies were identified following the inclusion criteria, from 2007 to 2019. The major respiratory viruses in Vietnam were influenza virus (IFV, 3.0%-40.6%), respiratory syncytial virus (RSV, 6.2%-48%) and rhinovirus (HRV, 8.8%-42.0%); Malaysia's primary respiratory viruses were IFV (3.0%-40.6%) and RSV (16.7%-51%); the main respiratory viruses of Philippines were IFV (6.0%-17.0%) and RSV (7.2%-31.6%). The prevalence of IFV typically rose in both rainy season and dry season, and the number of influenza A (IAV) cases was more than influenza B (IBV). Moreover, RSV infection mostly occurred in infants in these three countries, and was more common in the rainy season particularly in Vietnam and Malaysia. In addition, adenovirus (ADV), parainfluenza virus (PIV), human Boca virus (HBoV), coronavirus (HCoV), human metapneumovirus (HMPV), etc. have also been reported in the past five years. Conclusions Respiratory infectious viruses especially IFV, RSV and HRV are common in major neighboring countries of the South China Sea such as Vietnam, Malaysia and Philippines, underscoring the importance of enhancing surveillance and prevention of related diseases in neighboring provinces of China.
