Έχω βάλει links 10.000 φορές. Δεν θα ξανακάνουμε κάθε φορά την ίδια συζήτηση. Τράβα διάβασε την περσινή έκθεση για την εποχική γρίπη για να βρεις τις 3000 και 4000. Την δε Τσιοδρομελέτη επίσης την έχω παραθέσει πολλές φορές. Τελευταία φορά:
Across all ages, influenza was associated with an annual mean of 2,559 excess deaths, or 23.6 per 100,000 population.

Διάβασες τη μελέτη;
Η μελέτη αυτή αφορά τους θανάτους από κάθε είδους αιτία που συνδέεται με τις χαμηλές θερμοκρασίες και τους ιούς.
Στη μελέτη αυτή, για λόγους απλοποίησης, όλα τα αίτια θανάτου που σχετίζονται με κρύο ή ιούς, αποκαλούνται "γριπώδη".
Σου αναφέρω χαρακτηριστικά αποσπάσματα:
"Mortality attributable to cold temperatures was much higher than that attributable to influenza."
Στα δείγματα που λαμβάνονται υπ' όψη, οι θάνατοι από χαμηλές θερμοκρασίες (πνευμονίες κλπ) είναι υπερδιπλάσιοι των θανάτων από γρίπη.
Συμπεριλαμβάνονται στο ίδιο δείγμα.
"estimation needs to adjust for the confounding effect of ambient temperature, not only at the extremes but also at milder cold levels, which may account for substantially more
temperature-related deaths than extreme cold"
"For every day in the series, the number of deaths attributable to each influenza type/subtype
and to cold temperatures was calculated using a previously described method for DLNMs"
"The total attributable number of deaths is then given by
summing the contributions of each day."
"We calculated influenza- and temperature-attributable mortality for each of the four winter seasons"
"In this context, ‘cold temperatures’ means lower than the minimum mortality temperature, which is the point where mortality is lowest; however, our model can estimate the mortality attributable to any temperature range, be it mild cold or extreme cold."
"There is an ongoing debate about whether the wintertime seasonal mortality excess is primarily driven by seasonal influenza [13,24] or cold temperatures [14,25].
In our study we found that mortality attributable to cold temperatures was several times higher than that attributable to influenza, with temperature explaining most of the within-year seasonal variation in mortality"
"Although it is true (and our results also indicate) that the magnitude of the overall winter excess mortality does correlate with the dominant influenza type/subtype for each season [13], influenza-attributable deaths appear to be a minority among all winter deaths. The majority is attributable to cold temperatures, independent of influenza, and that part is relatively constant each season."
"We could only study all-cause deaths, as no comprehensive coded cause-specific mortality data are available in Greece; for example, it would have been very useful to examine cardiac or ‘pneumonia and influenza’ (P and I) deaths, but unfortunately this was not possible."
Αφού πρώτα αντιληφθείς ότι ως "γριπώδες περιστατικό" στη συγκεκριμένη μελέτη αναφέρεται κάθε είδους επενέργεια του χειμώνα στην υγεία των πολιτών, θα καταλάβεις γιατί οι ίδιοι επιστήμονες, τις ίδιες χρονιές αναφέρονται σε 150-250 νεκρούς από γρίπη.
