弗吉尼亚州通报西北地区1例麻疹确诊 Harrisonburg一企业列为暴露点 全州今年累计180例
弗吉尼亚州卫生厅（Virginia Department of Health，VDH）10月17日通报，该州西北地区（Northwest Region）新增1例麻疹确诊病例，患者为一名近期曾在美国国内旅行的成年人。VDH表示，为保护患者隐私，不公布更多个人信息，卫生官员正协调追踪可能接触过病毒的人。
VDH公布的州内潜在暴露点只有一处：位于 Harrisonburg 的 Fair Hill Precision（4445 Lewis Byrd Road），暴露时段为10月12日（周一）上午8时至下午5时，以及10月13日（周二）上午8时至下午5时。VDH称，截至通报时，弗吉尼亚州2026年已报告180例麻疹病例；如再发现新的暴露点，将公布在该厅麻疹专题页面上。弗吉尼亚州今年5月至6月间曾在 Buckingham County 与 Cumberland County 出现麻疹疫情，VDH已于8月18日宣布该轮疫情结束。
VDH表示，大多数弗吉尼亚州居民已通过接种获得麻疹免疫，公众整体风险较低；在上述时段到过暴露点的人应通过该厅的简短问卷报告暴露情况，并确认自己是否接种过麻疹（MMR）疫苗或曾经患过麻疹。已接种两剂含麻疹成分疫苗、或在1957年之前出生的人，被视为已有保护，目前无需接受暴露后处置。未完全接种或不具备免疫力的人应尽快联系医疗提供者或当地卫生部门，讨论暴露后处置——这类处置只在较短的时间窗内有效。
VDH同时列出观察要求：暴露后21天内留意麻疹症状，最可能的发病区间为10月19日至11月3日；如出现症状应立即居家隔离，并先打电话联系医疗提供者、请对方通知当地卫生部门后再前往就诊。麻疹经空气传播，感染者呼吸、咳嗽或打喷嚏时即可传播，病毒在感染者离开后仍可在空气中存留最长两小时；初期症状多为超过101华氏度的发烧、流鼻涕、眼睛红肿流泪与咳嗽，暴露后7至14天出现，发病3至5天后皮疹从面部开始并蔓延至全身，患者在皮疹出现前4天至出现后4天具有传染性。
据VDH介绍，麻疹可通过安全有效的MMR疫苗预防，两剂疫苗可提供长期保护，弗吉尼亚州约95%的幼儿园儿童已完整接种；6至11个月大、将进行国际旅行或前往疫情地区的婴儿应提前接种一剂MMR疫苗，家长可向医疗提供者咨询。VDH问询中心电话为877-829-4682，周一至周五（节假日除外）上午8时至下午5时开放。（GSM 据弗吉尼亚州卫生厅 VDH 发布）
Virginia Reports Confirmed Measles Case in Northwest Region; Harrisonburg Business Listed as Exposure Site as State Total Reaches 180 in 2026
The Virginia Department of Health (VDH) reported on October 17 a confirmed case of measles in a resident of the state's Northwest Region. The patient is an adult who recently traveled domestically. VDH said it would not release additional information about the patient to protect privacy, and that health officials are coordinating an effort to identify people who might have been exposed.
VDH listed one potential exposure site in Virginia: Fair Hill Precision, at 4445 Lewis Byrd Road in Harrisonburg, on Monday, October 12 (8 a.m. to 5 p.m.) and Tuesday, October 13 (8 a.m. to 5 p.m.). To date in 2026, Virginia has reported 180 cases of measles, VDH said, and any additional exposure sites identified in the state will be posted on the VDH measles website. Virginia previously saw a measles outbreak in Buckingham and Cumberland counties in May and June of this year, which VDH formally declared over on August 18.
Most people in Virginia have immunity to measles through vaccination, so the risk to the general public is low, VDH said. Anyone who was at the exposure site at the listed times should report the exposure through VDH's short survey and find out whether they have been vaccinated for measles or have had measles previously. People who have received two doses of a measles-containing vaccine, or who were born before 1957, are considered protected and do not need post-exposure treatment at this time. People who are not fully vaccinated or otherwise immune should promptly contact their healthcare provider or local health department, as post-exposure treatments are effective only within a small timeframe.
VDH also advised exposed people to watch for measles symptoms for 21 days after the potential exposure, noting the most likely period to become sick is October 19 through November 3, 2026. Anyone who notices symptoms should immediately isolate at home and call a healthcare provider ahead of any visit, asking the provider to notify the local health department. Measles spreads through the air when an infected person breathes, coughs or sneezes, and the virus can remain in the air for up to two hours after the person leaves. Early symptoms — a fever above 101 degrees, runny nose, watery red eyes and a cough — usually start seven to 14 days after exposure; a rash begins on the face three to five days after symptoms start and spreads to the rest of the body, and patients are contagious from four days before the rash appears through four days after.
Measles is preventable through the safe and effective MMR vaccine, with two doses providing long-lasting protection, and about 95% of Virginia kindergarteners are fully vaccinated, according to VDH. Infants six through 11 months old who will travel internationally or to an outbreak setting should receive one dose of MMR vaccine before travel, and parents can talk to a healthcare provider with questions. The VDH Call Center can be reached at 877-829-4682, Monday through Friday (except holidays), 8 a.m. to 5 p.m. (GSM, based on the Virginia Department of Health release)
