This research output has an Altmetric Attention Score of 2329. 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 22 March 2026.
All research outputs
#4,096
of 34,634,910 outputs
Outputs from MMWR: Morbidity & Mortality Weekly Report
#154
of 5,636 outputs
Outputs of similar age
#185
of 462,890 outputs
Outputs of similar age from MMWR: Morbidity & Mortality Weekly Report
#19
of 98 outputs
Altmetric has tracked 34,634,910 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 5,636 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 276.4. This one has done particularly well, scoring higher than 97% 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 462,890 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 99% of its contemporaries.
We're also able to compare this research output to 98 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 80% of its contemporaries.
