Summary
Influenza A (H3N2) activity is declining in Canada, with most severe cases in seniors. Vaccine effectiveness against H3N2 was low, indicating a need for improved vaccine matching.
Area of Science:
- Public Health
- Virology
- Epidemiology
Background:
- The FluWatch program monitors influenza activity across Canada.
- Influenza A (H3N2) predominated the 2014-15 season.
Purpose of the Study:
- To summarize the weekly FluWatch report for February 8-14, 2015.
- To assess influenza activity and vaccine effectiveness in Canada.
Main Methods:
- Utilized data from sentinel laboratories, primary care practices, and hospitals.
- Aggregated and disseminated influenza surveillance indicators weekly.
Main Results:
- Influenza activity declined, with widespread activity in seven regions.
- Influenza-like illness consultation rates and laboratory detections decreased.
- 4,817 hospitalizations and 342 deaths reported; most cases in adults over 65.
- Influenza A (H3N2) showed poor vaccine match; vaccine effectiveness was low.
Conclusions:
- Influenza A (H3N2) remains the dominant strain, primarily affecting seniors.
- The 2014-15 influenza season peak has passed.
- Continued monitoring by FluWatch is essential for public health response.

01:045-Number Summary
5.7K
In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

02:29Relative Strengths of Conjugate Acid-Base Pairs
52.6K
Brønsted-Lowry acid-base chemistry is the transfer of protons; thus, logic suggests a relation between the relative strengths of conjugate acid-base pairs. The strength of an acid or base is quantified in its ionization constant, Ka or Kb, which represents the extent of the acid or base ionization reaction. For the conjugate acid-base pair HA / A−, the ionization equilibrium equations and ionization constant expressions are

02:56The Fossil Record
27.5K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...

The reaction between a Brønsted-Lowry acid and water is called acid ionization. For example, when hydrogen fluoride dissolves in water and ionizes, protons are transferred from hydrogen fluoride molecules to water molecules, yielding hydronium ions and fluoride ions:
