moja baba je rodila desetoro dece, prirodnom selekcijm prezivelo troje. svima koji se i dalje uzdaju u prirodnu selekciju iskreno zelim mnogo mnogo vise srece
Methods
In this modelling study, we used Covasim, a stochastic individual-based model for transmission of SARS-CoV-2, calibrated to the UK epidemic. The model describes individuals' contact networks stratified into household, school, workplace, and community layers, and uses demographic and epidemiological data from the UK. We simulated six different scenarios, representing the combination of two school reopening strategies (full time and a part-time rota system with 50% of students attending school on alternate weeks) and three testing scenarios (68% contact tracing with no scale-up in testing, 68% contact tracing with sufficient testing to avoid a second COVID-19 wave, and 40% contact tracing with sufficient testing to avoid a second COVID-19 wave). We estimated the number of new infections, cases, and deaths, as well as the effective reproduction number (R) under different strategies. In a sensitivity analysis to account for uncertainties within the stochastic simulation, we also simulated infectiousness of children and young adults aged younger than 20 years at 50% relative to older ages (20 years and older).
Findings
With increased levels of testing (between 59% and 87% of symptomatic people tested at some point during an active SARS-CoV-2 infection, depending on the scenario), and effective contact tracing and isolation, an epidemic rebound might be prevented. Assuming 68% of contacts could be traced, we estimate that 75% of individuals with symptomatic infection would need to be tested and positive cases isolated if schools return full-time in September, or 65% if a part-time rota system were used. If only 40% of contacts could be traced, these figures would increase to 87% and 75%, respectively. However, without these levels of testing and contact tracing, reopening of schools together with gradual relaxing of the lockdown measures are likely to induce a second wave that would peak in December, 2020, if schools open full-time in September, and in February, 2021, if a part-time rota system were adopted. In either case, the second wave would result in R rising above 1 and a resulting second wave of infections 2·0–2·3 times the size of the original COVID-19 wave. When infectiousness of children and young adults was varied from 100% to 50% of that of older ages, we still found that a comprehensive and effective test–trace–isolate strategy would be required to avoid a second COVID-19 wave.
Interpretation
To prevent a second COVID-19 wave, relaxation of physical distancing, including reopening of schools, in the UK must be accompanied by large-scale, population-wide testing of symptomatic individuals and effective tracing of their contacts, followed by isolation of diagnosed individuals.
Oni tako vide rešenje suprotnosti između potrebe za kontrolom i nepopularnosti koje takva kontrola sa sobom nosi. Pa će doneti neke mere, da se kaže da su nešto uradili, ali ih neće silom nametnuti, da bi odgovornost za eventualne loše posledice prebacili na one koji treba dobrovoljno da ih sprovode i sami osmisle tobožnje "detalje". Iako u jednoj po svemu heterogenoj masi veoma različitih osoba to ni nije tehnički moguće.[url=http://beobuild.rs/forum/viewtopic.php?p=767949#p767949:2b26rxd9 je napisao(la):astrodule » 21 Aug 2020 09:32 am[/url]":2b26rxd9]
Nebitno da li neko podržava mere ili ne, poenta je da Država ne kontroliše mere koje je ona sama donela, a to je najvažnije i to mnogo govori o Državi.
Ne, to nije dobra analiza suštine situacije iako u praksi jeste nužno. Taj problem se ustvari svodi na jednostavnu činjenicu da se društvo UVEK sastoji iz grupa veoma različitih shvatanja i osobina. Mnogi će dobrovoljno poslušati uputstva koja po njihovom shvatanju imaju smisla, ali će uvek preostati mnogo onih koji misle suprotno ili koje prosto niti je briga niti uopšte znaju išta što je izvan granica nekog njihovog ličnog kruga ljudi i sopstvenih briga. A poseban problem je što su mnogi spremni da doprinesu društvu samo u istoj meri u kojoj oni misle da je društvo doprinelo NJIHOVOM blagostanju. Pa svako svoje krajnje sebično ponašanje obrazlažu tobožnjom ravnotežom između onoga što su primili i što daju.[url=http://beobuild.rs/forum/viewtopic.php?p=767964#p767964:yw4fdx17 je napisao(la):astrodule » 21 Aug 2020 10:07 am[/url]":yw4fdx17]Za to je samo Država kriva koja uporno insistira na ličnoj odgovornosti, a znamo da kod nas to ne postoji i da postoji samo pretnja kaznom i kažnjavanje (Oko sokolovo je odličan primer)
