Patients of new type influenza are increasing rapidly even in
my town. I have received the report of patients everyday
from the medical society of my town.
There are many young patients. The age distribution of patients
is not ordinary. Today I received the newest report, and
the age distribution is the next.
The total of patients were 1,682.
age(0-5) 131 (7.7%)
(6-12) 634 (37.7%)
(13-15) 434 (25.8%)
(16-18) 163 (9.7%)
(19-64) 313 (18.6%)
(over 65) 7 (0.4%)
That is to say, junior high school students are the most,
and primary school students are the second, because
a period of a primary school is six years.
In three years, primary school students are 18.8%.
I can't understand why patients of high school students
decrease suddenly. Is there difference of immunity
between junior high school students and high school students?
Difference of their age is only three years.
Why are students of a primary school and a junior high school
the main target of new type influenza?
This new type influenza must have the specific character of
immunity.
Is there the cliff of immunity at the age of fifteen years old?
