  • Disease & Illness Seasonality & Waves

    ... to examine why seasonal waves go down with only 5%-20% of the
    populaton infected

    ... to examine why some strains dominate and others disappear

    ... to examine why flu is almost yearround in the tropes but dies in warmer
    weather in regions more distant from the equator

    ... to examine where/how the new strains emerge than then become dominant

    ... to examine how immunity builds up and thus selects on dominance of
    new strains

    Re: seasonality,waves

    new particularly successful strains usually cause a first strong,early
    wave in USA,Europe and then becomes "normal" in the next years
    once immunity had built up

    below for the UK (couldn't easily find data from USA before 1997 ?)

    also demonstrating the mystery why flu declined so much in the UK
    since 2000 (but not in other countries)

        Re: seasonality,waves

        seasonal diseases , diseases that cause more deaths in winter than in summer in the USA
        ordered by the magnitude of winter/summer quotient, not by total deaths

        1.) almost all respiratory deaths
        2.) other viral (except HIV) and chlamydial infection
        3.) mening- anything
        4.) sudden death, cause unknown
        5.) most mental/nerval diseases, like Alzheimer,Parkinson,senility,dementia
        6.) malnutrition,nutritional conditions, especially marasmus
        7.) septicemia

        8.) almost all cardiovascular deaths , (ratio small (~1.05), but total number big)

        9.) cancer (the ratio is very small (~1.02 , maybe 1.03 in lung cancer))

        [to be updated and extended]
        I'm making tables for ICD7,ICD8,ICD9a,ICD9b,ICD10 deaths with their seasonality
        and influenza-dependence

          Re: Disease & Illness Seasonality & Waves

          there are small (but significant because of the large numbers) differences
          in the seasonality of the various cancer deaths.

          lung,breast,prostate cancer deaths occur 2-3% more often
          in winter than in summer, independent from the severety of the flu-season
          while pancreas,skin cancer deaths are balanced between summer and winter.

            most of the various cardiovascular death, that sound so different
            to me in symptoms and causes, still have all a quite uniform ~11%
            winter-preference. The preference for severe flu-seasons is lower,
            at ~2% in average.

              Re: Disease & Illness Seasonality & Waves

              deaths from infectious diseases became rare these days.
              Except pneumonia, which will be handled in the respiratory group later.
              Most are Septicaemia - those a bit more seasonal than cardiovascular
              Very seasonal - comparable with pneumonia - are deaths from
              viral meningitis and other viral infections, but it's not so significant,
              it could be (bad) luck, the numbers are small.

                as expected, deaths from respiratory causes are most seasonal.
                They are dominated by Pneumonia,Bronchopneumonia (unspecified)
                with caused 39&#37; more deaths in winter than in summer and
                ~16% more deaths in severe flu-winters as compared to mild flu-winters.
                The last numer(16%) is surprisingly low, when you consider that deaths
                attributed to flu were 500% higher in those seasons.
                Maybe it's because flu-B kills well by pneumonia but not by cardiovascular
                causes and so seasons dominated by flu-B are considered mild.
                The other common respiratory death condition is chronic obstructive
                pulmonary disease, which is half as seasonal as pneumonia
                but ~double as seasonal as cardiovascular deaths.

                Some of the respiratory conditions are "highly" seasonal,
                ~50% more winter deaths than summer deaths,
                while others are only lightly elevated.
                Maybe some medical expert can explain why ...

                        among the deaths from inner organ-problems we have the highest seasonality
                        in kidney-related deaths. Prostate deaths show a high correlation with severe
                        flu seasons, but small significance (flu won't go into prostate or kidney ?!)
                        Most deaths in this category are from cirrhosis of liver, which has low seasonality,
                        still more than cancer.

                          we already know that seasonality of deaths is _worse_ in the Southern states,
                          Europe and USA, although that's improving in the last decades.

                          Without flu, in mild flu-seasons we have an almost linear decline from Jan to Aug
                          (7 months) and then a linear increase Aug-Jan (5 months --> steeper)

                          what is it ? Hard to imagine why spring,fall are worse than August wrt. deathss.
                          Is it all just because of (unknown ?) respiratory viruses that spread better in cold
                          weather ? Differences in immunity ? Nutrition ?
                          We mostly live in heated rooms in winter
