Among adults, COVID-19 hospitalization rates increase with age. Data from the COVID-19-Associated Hospitalization Surveillance Network were analyzed to estimate population-based COVID-19-associated hospitalization rates during October 2023-April 2024 and identify demographic and clinical characteristics of adults aged ≥18 years hospitalized with COVID-19. Adults aged ≥65 years accounted for 70% of all adult COVID-19-associated hospitalizations, and their COVID-19-associated hospitalization rates were higher than those among younger adult age groups. Cumulative rates of COVID-19-associated hospitalization during October 2023-April 2024 were the lowest for all adult age groups during an October-April surveillance period since 2020-2021. However, hospitalization rates among all adults aged ≥75 years approached one COVID-19-associated hospitalization for every 100 persons. Among adults hospitalized with COVID-19, 88.1% had not received the 2023-2024 formula COVID-19 vaccine before hospitalization, 80.0% had multiple underlying medical conditions, and 16.6% were residents of long-term care facilities (LTCFs). Guidance for adults at high risk for severe COVID-19 illness, including adults aged ≥65 years and residents of LTCFs, should continue to focus on adopting measures to reduce risk for contracting COVID-19, advocating for receipt of recommended COVID-19 vaccinations, and seeking prompt outpatient antiviral treatment after receipt of a positive SARS-CoV-2 test result.

美国 18 岁以上成年人与 COVID-19 相关的住院情况 - COVID-NET，12 个州，2023 年 10 月至 2024 年 4 月。


在成年人中，COVID-19 住院率随着年龄的增长而增加。对来自 COVID-19 相关住院监测网络的数据进行了分析，以估计 2023 年 10 月至 2024 年 4 月期间基于人群的 COVID-19 相关住院率，并确定因 COVID-19 住院的 18 岁以上成年人的人口和临床特征。年龄≥65岁的成年人占所有成人COVID-19相关住院治疗的70%，他们的COVID-19相关住院率高于较年轻的成人年龄组。 2023 年 10 月至 2024 年 4 月期间与 COVID-19 相关的累计住院率是自 2020 年至 2021 年以来 10 月至 4 月监测期间所有成人年龄组中最低的。然而，所有 75 岁以上成年人的住院率接近每 100 人就有 1 人因 COVID-19 住院。在因 COVID-19 住院的成年人中，88.1% 的人在住院前未接种 2023-2024 年配方的 COVID-19 疫苗，80.0% 的人患有多种基础疾病，16.6% 的人是长期护理机构 (LTCF) 的居民。针对患有严重 COVID-19 疾病的高风险成年人（包括年龄≥65 岁的成年人和 LTCF 居民）的指南应继续重点关注采取措施降低感染 COVID-19 的风险，提倡接种推荐的 COVID-19 疫苗，收到 SARS-CoV-2 检测结果呈阳性后立即寻求门诊抗病毒治疗。
