this study aims to describe the epidemiological characteristics of yellow fever in Brazil in the period 2000-2012.
this is a descriptive ecological epidemiological study, using information from Ministry of Health databases.
326 cases of yellow fever were confirmed in Brazil during this period, with 156 deaths and an average case fatality rate of 47.8%; the young male adult age group was the most affected; in epizootic terms, 2,856 suspected cases of yellow fever in non-human primates were reported and 31.1% of these were confirmed by laboratory tests; during the study period the area in which sylvatic transmission of the disease occurs was found to have expanded to densely population regions, such as South, Southeast and Midwest Brazil.
the risk of urban yellow fever transmission persists, as sylvatic incidence of the disease has expanded to regions with high Aedes aegypti infestation, this being the mosquito responsible for urban transmission of the disease.
This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 April 2019.
All research outputs
#9,421,107
of 29,868,835 outputs
Outputs from Epidemiologia e Serviços de Saúde
#151
of 507 outputs
Outputs of similar age
#119,687
of 411,504 outputs
Outputs of similar age from Epidemiologia e Serviços de Saúde
#1
of 24 outputs
Altmetric has tracked 29,868,835 research outputs across all sources so far. This one has received more attention than most of these and is in the 68th percentile.
So far Altmetric has tracked 507 research outputs from this source. They receive a mean Attention Score of 3.5. This one has gotten more attention than average, scoring higher than 69% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 411,504 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 24 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 95% of its contemporaries.
