佐治亚州麻疹病例升至22例 梅肯县新增一例未接种居民 与宾夕法尼亚州疫情相关联
据FOX 5亚特兰大10月14日报道，佐治亚州卫生官员确认，该州梅肯县一名未接种疫苗的居民确诊麻疹，使该州今年麻疹病例总数升至22例，是2025年全年10例的两倍多。这名感染者正在家中隔离，未接种疫苗的密切接触者正在隔离中。
州公共卫生部表示，这名感染者没有旅行史，但曾接触一名与宾夕法尼亚州持续麻疹疫情相关的确诊病例；卫生部门正在追踪可能接触过病毒的人士，尚未公布州内可能发生社区暴露的具体地点。宾州今年的麻疹疫情已报告超过1100例。
州流行病学家谢丽·德伦泽克表示，一剂MMR疫苗对麻疹的防护效果约为93%，两剂约为97%。麻疹经空气传播，感染者离开后病毒可在空气中保持传染性最长两小时；症状通常在接触后7至14天出现，最长可达21天。
Georgia Measles Cases Reach 22 After Unvaccinated Macon County Resident Tests Positive
FOX 5 Atlanta reported on October 14 that Georgia health officials confirmed a new measles case in an unvaccinated Macon County resident, bringing the state's total to 22 cases this year, more than double the 10 cases reported in all of 2025. The infected person is isolating at home, and unvaccinated close contacts are quarantining.
The Georgia Department of Public Health said the person has no history of travel but was exposed to a confirmed case connected to an ongoing outbreak in Pennsylvania, and that it is tracking people who may have been exposed; it has not released the specific locations of potential community exposures in Georgia. Pennsylvania's measles outbreak has surpassed 1,100 cases this year.
State epidemiologist Dr. Cherie Drenzek said one dose of the MMR vaccine offers roughly 93% protection against measles and two doses about 97%. Measles spreads through the air and can remain infectious for up to two hours after an infected person leaves a room; symptoms typically appear seven to 14 days after exposure, and can take up to 21 days.
