Ticks and tick-borne microbes identified through passive and active surveillance in Alaska
Hahn MB , Hojgaard A , Disler G , George W , Droghini A , Schlaht R , Durden LA , Coburn S , Gerlach R , Eisen RJ . J Med Entomol 2023 60 (5) 1099-1107 Rapid environmental change in Alaska and other regions of the Arctic and sub-Arctic has raised concerns about increasing human exposure to ticks and the pathogens they carry. We tested a sample of ticks collected through a combination of passive and active surveillance from humans, domestic animals, and wildlife hosts in Alaska for a panel of the most common tick-borne pathogens in the contiguous United States to characterize the diversity of microbes present in this region. We tested 189 pooled tick samples collected in 2019-2020 for Borrelia spp., Anaplasma spp., Ehrlichia spp., and Babesia spp. using a multiplex PCR amplicon sequencing assay. We found established populations of Ixodes angustus Neumann (Acari: Ixodidae), Ixodes uriae White (Acari: Ixodidae), and Haemaphysalis leporispalustris Packard (Acari: Ixodidae) in Alaska, with I. angustus found on a variety of hosts including domestic companion animals (dogs and cats), small wild mammals, and humans. Ixodes angustus were active from April through October with peaks in adult and nymphal activity observed in summer months (mainly July). Although no known human pathogens were detected, Babesia microti-like parasites and candidatus Ehrlichia khabarensis were identified in ticks and small mammals. The only human pathogen detected (B. burgdorferi s.s.) was found in a tick associated with a dog that had recently traveled to New York, where Lyme disease is endemic. This study highlights the value of a combined passive and active tick surveillance system to detect introduced tick species and pathogens and to assess which tick species and microbes are locally established. |
Family and home asthma services across the Controlling Asthma in American Cities Project
Brown AS , Disler S , Burns L , Carlson A , Davis A , Kurian C , Weems D Jr , Wilson K . J Urban Health 2011 88 Suppl 1 100-12 Asthma is among the most common chronic childhood diseases, affecting 6.8 million children nationwide. The highest rates of morbidity and mortality associated with the disease occur among those living in the inner city. Because asthma is a complex disease affected by physiological, social, environmental, and behavioral factors, interventions to reduce its morbidity burden need to address multiple determinants of health. In response to this need, the Centers for Disease Control and Prevention developed a multisite cooperative agreement for the Controlling Asthma in American Cities Project (CAAC), with the primary goal of developing innovative, effective community-based interventions. All CAAC sites found a need for family and home asthma services (FHAS) and developed multicomponent (e.g., asthma self-management, social services, coordinated care) and multitrigger environmental interventions. This paper presents a synthesis of key program variables and process indicators for six CAAC FHAS interventions for consideration by communities, coalitions, or programs planning to implement similar activities. |
