To describe the temporal and geographic progression of the Lyme disease epidemic in New York State from 1977 through 1989.
Communicable disease surveillance system.
Statewide.
The progression of the epidemic was examined by analyzing trends in Lyme disease cases reported to the state surveillance system, town and county Lyme disease incidence rates, Lyme disease hospital discharge rates, and the distribution of Ixodes dammini ticks obtained from surveillance efforts and submitted for identification.
The number of confirmed Lyme disease cases in New York has increased with concurrent increases in the number of hospital discharges. The number of counties endemic for Lyme disease increased from four to eight between 1985 and 1989. The number of counties with documented I dammini ticks increased from four in 1985 to 22 in 1989. Incidence of the disease also increased within known endemic counties.
Tick surveillance indicated that the range of I dammini has expanded annually into areas up to 384 km from the original known endemic areas of Long Island, NY, and Connecticut. Cumulative data from human surveillance resources document both temporal increases and geographic expansion of the Lyme disease epidemic in New York.
描述1977年至1989年纽约州莱姆病疫情的时间和地理发展情况。
传染病监测系统。
全州范围。
通过分析向州监测系统报告的莱姆病病例趋势、城镇和乡村莱姆病发病率、莱姆病出院率，以及从监测工作中获取并送检鉴定的达敏硬蜱（Ixodes dammini）分布情况，来研究疫情的发展。
纽约州确诊的莱姆病病例数增加，同时出院人数也增加。1985年至1989年间，莱姆病流行的县从4个增加到8个。有记录的达敏硬蜱的县从1985年的4个增加到1989年的22个。在已知的流行县内，该病的发病率也有所增加。
蜱虫监测表明，达敏硬蜱的活动范围每年都扩展到距离纽约长岛和康涅狄格州最初已知流行区达384公里的区域。来自人类监测资源的累积数据记录了纽约州莱姆病疫情在时间上的增加和地理上的扩展。
