Hospitalization of Infants and Children Aged 0–4 Years with
Laboratory-Confirmed COVID-19 — COVID-NET, 14 States, March 2020–February
2022
0-4歲小孩住院新冠病毒14州研究,2020年三月到2022年二月

Important strategies to prevent COVID-19 among infants and young children
include vaccination of currently eligible populations such as pregnant women,family members, and caregivers of infants and young children.
重要的方法防止新冠病毒對小孩包括接種疫苗如懷孕婦女,家庭成員,照顧小孩的人

During the period of Omicron predominance (December 19, 2021–February 19,
2022), weekly COVID-19–associated hospitalization rates per 100,000 infants
and children aged 0–4 years peaked at 14.5 (week ending January 8, 2022)
在主要是omicrom傳播(12月19,2021-2月19,2022),每周0-4歲小孩在住院高峰每十萬人
14.5位

During Omicron predominance, 63% of hospitalized infants and children had no
underlying medical conditions; infants aged <6 months accounted for 44% of
hospitalizations, although no differences were observed in indicators of
severity by age.
在主要為Omnicron傳播,63%住院嬰兒或小孩沒有既有疾病,嬰兒小於六個月佔了44%,雖然沒有顯示病重跟年紀有關係

Although infants aged <6 months are not currently eligible for vaccination,
evidence suggests that this age group can receive protection through passive
transplacental transfer of maternal antibodies acquired through vaccination
(9). CDC recommends that women who are pregnant, breastfeeding, trying to
become pregnant, or might become pregnant get vaccinated and stay up to date
with COVID-19 vaccination.
雖然嬰兒小於六個月目前無法接種疫苗,證據顯示小於六個月可以被動透過從母親的抗體取得疫苗抗體.美國CDC推薦懷孕的婦女接種新冠疫苗並且新冠疫苗目前保護有效期間

CDC recommends that women who are pregnant, breastfeeding, trying to become
pregnant, or might become pregnant get vaccinated and stay up to date with COVID-19
vaccination.
CDC推薦婦女已經懷孕,餵乳,嘗試懷孕,或可能懷孕接種新冠疫苗必且疫苗及時

結論:在0-4歲,嬰兒小於6個月最可能住院,比例佔44%,美國CDC推薦懷孕,餵乳婦女接種疫苗並且疫苗還是即時,因為嬰兒可以得到保護,並且推薦照顧0-4歲家人或照顧者接種疫苗,
假設台灣一年出生20萬,0-4歲(未滿5歲)100萬人口,每周住院高峰人口145位
