“…However, the most common virus that causes ILI is RSV which often occurs in children ( Kondratiuk et al, 2021 , Faye et al, 2022 ). ILI is commonly spread through contact with an infected person (direct or indirect) ( Fauzi et al, 2023 ), with an incubation period of 1–4 days ( Table 1 ) ( Stellrecht, 2017 ). In Saudi Arabia the number of cases infected with ILI is about 1424 from 2018 to 2021 ( MOH, 2021b ), however, the number of cases in the United States is 9 million to 49 million annually ( Spencer et al, 2022 , Jones et al, 2021 ), ( Blanchet Zumofen et al, 2023 ), which is considered a leading factor for high mortality and morbidity ( Mezlini et al, 2022 ).…”
