I know the author of this (and of the | linked Washington Post article) are trying to help people gain | clarity, but it worries me that it only serves to accelerate fear | and panic. | | These articles are making it sound as if the exponential part of | the curve will just continue on forever until it consumes the | whole population. The (self-admittedly) overly simplified | simulations aren't helping either. | | Front this article > | | _And here 's the kicker: even if we manage to "flatten the | curve" enough to meaningfully space out the case load, we're | still positioned to lose millions and millions of lives._ | | From the WaPo article > | | _This so-called exponential curve has experts worried. If the | number of cases were to continue to double every three days, | there would be about a hundred million cases in the United States | by May._ | | _Still, without any measures to slow it down, covid-19 will | continue to spread exponentially for months. To understand why, | it is instructive to simulate the spread of a fake disease | through a population._ | | It will continue to spread exponentially for months!? Millions & | millions of cases & or deaths? These are really sloppy and | dangerous ideas to put in peoples head. They are just plain | wrong, and not how pandemics play out in reality. | | Here is what the CDC says about how pandemics spread (Under the | 'COVID-19 Now a Pandemic' heading) | https://www.cdc.gov/coronavirus/2019-ncov/cases-updates/summ... | | _Pandemics of respiratory disease follow a certain progression | outlined in a "Pandemic Intervals Framework." Pandemics begin | with an investigation phase, followed by recognition, initiation, | and acceleration phases. The peak of illnesses occurs at the end | of the acceleration phase, which is followed by a deceleration | phase, during which there is a decrease in illnesses. Different | countries can be in different phases of the pandemic at any point | in time and different parts of the same country can also be in | different phases of a pandemic._ | | _Different parts of the country are seeing different levels of | COVID-19 activity. The United States nationally is currently in | the initiation phases, but states where community spread is | occurring are in the acceleration phase. The duration and | severity of each phase can vary depending on the characteristics | of the virus and the public health response._ | | So no, it will NOT continue exponentially for months. Especially | given the amount of isolation/ quarantine measures and canceling | of large events taking place. I think it is reasonable to expect | these measures will help us progress through to the deceleration | phase faster. | | Further-more, there is more and more evidence coming out | suggesting the in China where it started, they have already | entered the deceleration phase. This should be encouraging news | for us in USA where it is just beginning. | | https://www.aljazeera.com/programmes/newsfeed/2020/03/big-dr... | feanaro wrote: | What happens once China starts dismantling mitigations | currently in place, given that the majority of the population | is still naive to the virus? Is it reasonable to expect they | can wait out the virus disappearing completely by tracking all | active cases until they have recovered? | saberdancer wrote: | It's probably better to err on the side of caution than the | alternative. | xwdv wrote: | This is missing a couple things: | | 1) Cells should have random demographics such as male/female and | age, and a virus could respond differently to them | | 2) The virus should have some capability for mutation as it | spreads. (probability of changing variables from the initial | configuration by some percent) | wiz21c wrote: | How can I model the type of interaction between people.

I covered all the pathogens too, though I think I had | quite a few genes left to unlock. | | I've never played the original Plague Inc, so I can't tell | you the difference from experience, but according to | Wikipedia (https://en.wikipedia.org/wiki/Plague_Inc:_Evolved | , isn't it amazing that it has its own Wikipedia page?): | | _The core game of Plague Inc: Evolved is the same as Plague | Inc. - the player controls a plague which has infected | patient zero. The player must infect and kill the whole world | population by evolving the plague and adapting to various | environments. However, there is a time pressure to complete | the game before humans, the opponent, develop a cure for the | plague. [...] It also includes all of the expansion packs | from the original Plague Inc. game_ | | Great game concept, though still with some untapped potential | in my opinion. I keep getting inspired to replay it by the | news right now, but we really have much, much more urgent | things to attend to.
