Cambodia's MOH reports their 7th human H5N1 infection for 2024 - and the 2nd one in past two days - with the discovery that a 5 y.o. girl living in the same household as Saturday's case (who is reportedly mildly symptomatic) has tested positive for the virus. 
While we don't have word on the exact clade of these two most recent H5N1 cases, they are very likely the older 2.3.2.1c clade of H5N1, which predates the emergence of clade 2.3.4.4b and has been identified in 10 of the last 11 cases in Cambodia.

-
While Cambodia has an excellent reputation for reporting and investigating cases or clusters, it takes a bit of luck for these cases to be detected. Mild or moderate cases are more likely to go unrecognized, since the best chance for detection comes when a patient is hospitalized.
Of the 13 H5N1 cases reported by Cambodia over the past 18 months, only 3 have been in adults and all of them survived.  Among the 10 children infected - while several had mild symptoms -half (n=5) died. 
Younger people (< 40) seem to be more susceptible to H5 infections while the opposite appears true for H7N9 (see H7N9: The Riddle Of The Ages). This affinity for the H5N1 virus to infect younger patients has evoked a number of theories, but has never been adequately explained.
DJ, We are learning more on flu...

But, as the chart below illustrates, the 18 known subtypes are divided into two basic groups;  Group 1 and Group 2.

and immunity within the group of flu may offer protection for more types of the same group of flu.
