| national assessment of human health effects of climate change in portugal: approach and key findings. | in this study we investigated the potential impact of climate change in portugal on heat-related mortality, air pollution-related health effects, and selected vectorborne diseases. the assessment used climate scenarios from two regional climate models for a range of future time periods. the annual heat-related death rates in lisbon may increase from between 5.4 and 6 per 100,000 in 1980-1998 to between 8.5 and 12.1 by the 2020s and to a maximum of 29.5 by the 2050s, if no adaptations occur. the ... | 2006 | 17185290 |
| laboratory diagnosis of lyme borreliosis at the portuguese national institute of health (1990-2004). | lyme borreliosis is considered to be an emerging infection in some regions of the world, including portugal. the first portuguese human case of lyme borreliosis was identified in 1989. since 1999, this disease is considered a notifiable disease (ddo) in portugal, but only a few cases are reported each year, which does not allow consistent analysis of risk factors and the impact on public health. in this study the authors analyse the data available at the centre for vectors and infectious disease ... | 2006 | 17130658 |
| genetic diversity of borrelia burgdorferi sensu lato in ticks from mainland portugal. | to date borrelia lusitaniae is the only genospecies of borrelia burgdorferi sensu lato isolated from ixodes ricinus ticks collected in portugal and tunisia. this suggests that the genospecies diversity of b. burgdorferi sensu lato decreases toward the southwestern margin of its old world subtropical range. in order to further explore the genetic diversity of b. burgdorferi sensu lato from this region, 55 i. ricinus and 27 hyalomma marginatum questing adults, collected during the spring of 1998 f ... | 2000 | 10834965 |
