There are 18 known HA subtypes (H1–H18) and 11 known NA subtypes (N1–N11). HA subtypes are further divided into two groups. Group 1 HA includes H1, H2, H5, H6, H8, H9, H11, H12, H13, H16, H17, and H18, whereas group 2 HA includes H3, H4, H7, H10, H14, and H15. Both influenza A and B viruses infect humans and can cause severe illness or death.

The correct way to specify a heading level higher than 6 is to include the attribute aria-level="7" (or whatever level you prefer). If you apply this attribute to anything other than h1 - h6 you will also need role="heading". Therefore any of the following "h7" examples are valid and correct according to w3.
The analysis used a correlation matrix, formed on the standardized frequencies. At first, an analysis was made using 14 variables (H1*, H1a, H1b, H2a1, H3, H4, H5*, H5a, H6a, H6b, H7, H8, H11), which we had previously analyzed in various Eurasian populations (Loogväli et al. 2004), or which, in the case of H20 could be deduced from HVS-1 data
Xenon Headlight Color Temperature 8000K: Xenon bulbs - 8000K has an approximately 2900lm output, which is about 3x the light output of the traditional halogen light and slightly less light output compared to the 6000K. While it has a bit lesser light output, it emits bluer light than the 6000K. Xenon Headlight Color Temperature 10000K:
