The relationship between weather and influenza and pneumonia mortality was examined retrospectively using daily data from 1980-2009 in Auckland, New Zealand, a humid, subtropical location. Mortality events, defined when mortality exceeded 0.95 standard deviation above the mean, followed periods with anomalously cold air (ta.m. = -4.1, p<0.01; tp.m. = -4.2, p<0.01) and/or anomalously dry air (ta.m. = -4.1, p<0.01; tp.m. = -3.8, p<0.01) by up to 19 days. These results suggest that respiratory infection is enhanced during unusually cold conditions and during conditions with unusually low humidity, even in a subtropical location where humidity is typically high.

This research output has an Altmetric Attention Score of 292. 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 11 May 2025.
All research outputs
#151,868
of 34,547,233 outputs
Outputs from Influenza & Other Respiratory Viruses
#24
of 1,611 outputs
Outputs of similar age
#2,327
of 340,624 outputs
Outputs of similar age from Influenza & Other Respiratory Viruses
#2
of 12 outputs
Altmetric has tracked 34,547,233 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 1,611 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 20.8. This one has done particularly well, scoring higher than 98% 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 340,624 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 12 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 83% of its contemporaries.
