A multi-species epidemic model with spatial dynamics.

A model is formulated that describes the spatial propagation of a disease that can be transmitted between multiple species. The spatial component consists, for each species, of a certain number of patches that make up the vertices of a digraph, the arcs of which represent the movement of the various species between the patches. In each of the patches and for each species, a susceptible-exposed-infectious-recovered (SEIR) epidemic model describes the evolution of the disease status of individuals. Also in each patch, there is transmission of the disease from species to species. An analysis of the system is given, beginning with results on the mobility component. A formula is derived for the computation of the basic reproduction number R(0) for sspecies and npatches, which then determines the global stability properties of the disease free equilibrium. Simulations for the spread of a disease in one species and two patches are presented.

Large summertime influenza A outbreak among tourists in Alaska and the Yukon Territory.

We investigated a large summertime outbreak of acute respiratory illness during May-September 1998 in Alaska and the Yukon Territory, Canada. Surveillance for acute respiratory illness (ARI), influenza-like illness (ILI), and pneumonia conducted at 31 hospital, clinic, and cruise ship infirmary sites identified 5361 cases of ARI (including 2864 cases of ILI [53%] and 171 cases of pneumonia [3.2%]) occurring primarily in tourists and tourism workers (from 18 and 37 countries, respectively). Influenza A viruses were isolated from 41 of 210 patients with ILI at 8 of 14 land sites and 8 of 17 cruise ship infirmaries. Twenty-two influenza isolates were antigenically characterized, and all were influenza A/Sydney/05/97-like (H3N2) viruses. No other predominant pathogens were identified. We estimated that >33,000 cases of ARI might have occurred during this protracted outbreak, which was attributed primarily to influenza A/Sydney/05/97-like (H3N2) viruses. Modern travel patterns may facilitate similar outbreaks, indicating the need for increased awareness about influenza by health care providers and travelers and the desirability of year-round influenza surveillance in some regions.

A survey of refugee health assessments in the United States.

We conducted a survey among nine geographically dispersed, large metropolitan refugee health programs to estimate the number of U.S. refugee arrivals during 1997 and 1998, the number receiving health assessments, and the percentage of sites offering health services. The nine sites received an estimated 40% of all U.S. refugee arrivals during the study period. Of these refugees, 76% received a health assessment. The completeness of health assessments, including services offered, varied by site; some services were provided by the private sector. Most sites offered services for infectious diseases and vaccinations. While 78% of the sites offered mental health care, but only 33% actually performed mental status examinations. These statistics show that such health services need to be provided on a broader basis and possibly reflect a need to address cultural and language barriers that might be preventing their delivery to this diverse population.
