Figure 1. Respiratory viruses detected from September 2020 to October 2021, shown by virus (a) and rhinovirus genotype (b). Changes in COVID-19-related public health and social measures during this period are labelled in (a). *Strict social measures to mitigate COVID-19 from January 2021 included tightening of social distancing measures, restrictions on gatherings and dining, and closure of leisure venues. Quarantine of inbound travellers was also extended from 14 to 21 days. HMPV, human metapneumovirus; HCoV-HKU1, human coronavirus HKU-1; HCoV-229E, human coronavirus 229E; HPIV 1-4, human parainfluenza viruses 1-4; RSV, respiratory syncytial virus.
Figure 2. Rhinovirus genetic diversity detected in paediatric samples in Hong Kong during September 2020 – October 2021. Maximum likelihood trees show phylogenetic relationships of the VP4/2 genes. Phylogenetic tips in red represent samples from this study, labelled by genotype and number of positive samples.
Figure 3. Time-scaled phylogenetic trees of the three most prevalent rhinovirus genotypes circulating in Hong Kong during the study period. Grey bars at nodes indicate 95% CIs of the estimated time to most recent common ancestor (tMRCA).
