加州现首例 I 型猴痘病例：公共卫生部呼吁接种两剂 JYNNEOS 疫苗
加州公共卫生部（CDPH）发布第 NR26-015 号新闻稿，确认旧金山出现加州首例 I 型（Clade I）猴痘病例，并呼吁符合条件的人群尽快完成两剂 JYNNEOS 疫苗接种。这是自2024年11月以来加州确诊的第7例 I 型猴痘病例。
公共卫生部表示，这名患者未接种过猴痘疫苗，是国际旅行者的密切接触者，目前正在住院治疗，病情正在好转。与此同时，加州 II 型（Clade II）猴痘病例呈上升趋势，2026年周平均病例为14.5例，高于2024年的5.8例与2025年的3.4例，患者大多未接种疫苗。
加州公共卫生部主任兼州公共卫生官员 Erica Pan 博士表示，接种疫苗仍是预防猴痘重症最有效的方法。公共卫生部建议有暴露风险的人群接种两剂 JYNNEOS 疫苗，现阶段不建议接种加强针，并提醒出现皮疹等症状者及时就医并避免密切接触他人。

California Reports First Clade I Mpox Case; CDPH Urges JYNNEOS Vaccination
The California Department of Public Health (CDPH), in news release NR26-015, confirmed the first Clade I mpox case in San Francisco and urged eligible residents to complete the two-dose JYNNEOS vaccine series. It is the seventh Clade I mpox case identified in California since November 2024.
CDPH said the patient, who was unvaccinated, is a close contact of an international traveler and is hospitalized and improving. Meanwhile, Clade II mpox cases are rising in California, averaging 14.5 cases per week in 2026, up from 5.8 in 2024 and 3.4 in 2025, with most patients unvaccinated.
Dr. Erica Pan, CDPH Director and State Public Health Officer, said vaccination remains the most effective way to prevent severe mpox illness. CDPH recommends two doses of JYNNEOS for people at risk, does not currently recommend booster doses, and advises anyone with symptoms such as a rash to seek care promptly and avoid close contact with others.
