COVID-19: U.S. sees biggest jump in confirmed cases, 26,400 in a day

Excersize and sun light is important aswell.

MICROBIAL GROWTH http://www2.hawaii.edu/~johnb/micro/medmicro/medmicro.5.html
lag, log, flat, done; overlap anyone?
Bacteria divide and reproduce asexually. Binary Fission and everything is equally divided between the two daughter cells.

Time it takes for a single cell to go from one division to the next: generation time or doubling time. This is also the time it takes for a population to double. For many "typical" bacteria under "ideal" conditions this doubling time may be as fast as 20 minutes.
Bacterial population increases exponentially or logarithmically. That is:
(x)(2)n , where x=initial number of bacterial cells and n=the number of generations.
[Remember that if 2n=y, then n=log2y].
This is also a geometric progression: 2, 2x2, 2x2x2, 2x2x2x2, etc.
Bacterial Growth Curve:

When an organism is inoculated into a nutrient solution 4 distinct growth phases are noted:
1.) Lag Phase - where the organisms are "getting used to the medium and physical conditions" - that is they are inducing the necessary enzymes for growth.
2.) Logarithmic (Log) Growth Phase - This is the phase where the generation time is measured. The more ideal the conditions, the faster the growth - up to the maximum growth rate for the species.
3.) Stationary Phase - during this phase the number of new cells equals the number of dead cells so that there is no net increase in viable cells. Nutrient are becoming depleted, the pH is changing, toxic wastes are building up, oxygen levels are becoming depleted.
4.) Death Phase - Rate of cell death is faster than regeneration. Death may accelerate and become exponential.
doubling time, yield

Wasn't refered to the bacteria, got a mate NHS ambulance desk, not many C19 related call outs, but loads and loads way more than normal heart attack related calls, a LOT dead this week, I blame the sudden in activity.

50ish year old died with his 2 kids alone with in the house, nasty :(
 
ambulance desk,
growth curves apply to populations other than microbes, it is a food thing usually, carbon source is required, though virus is as you say a cat of a different color, but doubling time and exponential growth models are in use by lotsa planners. Dagone virus hijack the cell's replication mechanism to reproduce copies of itself which are disbursed when the cell lyses, pops and everyviri moves along locate another cell, is the current model in molbio biz. Sez virus is not actually alive but just genetic material wrapped in protein coat. clever system, no doubt. Since they dont 'eat' per se, the 'food' is lack of 'host' for the 'party' as it were. Which means that the lag log plateau death model does not cleave to the bacterial numbers as slavishly but rhyme pretty well.
If accurate numbers were available it would be a cinch to run the numbers backwards and forwards to learn a coupla things, no?
Agree that ticker attack a cause of death that ranks right up there with medical mistakes, lol.
Always good to know an EMT or two, you are in good stead there. In the states EMT's, Fire, Police have to watch for all manner of crazy when they go out on a call. To hassle an emt out there keeping it together in emergency on a daily basis is unthinkable.
Mr T, you got vegemite in your neighborhood?

Virus, needs to grow in it's host ( human ) and then leave said hoste to look for other food sources, other humans, at first exponential growth from 1% to 50% pretty damn quickly, as lots of hosts to jump into, then more people are immune and less people to transfer to.

When you get to 80%, very hard to find new hosts and infections slow and only 20% left 1/5th population.

It's pretty much a good bet, that 80%'s very near in Italy and London ( rest of UK lagging ) looking at the data, should start dropping nicely there infections needing hospital wise, finally.

Vegemite, I guess so, but not into Vegie stuff!!

Well, people with underlying heart issue will likely have heart attacks under great stress, which we are certainly going through at this time.

Stress caused by massively over hyped fear of a virus, fear of losing job, stuck in a house scared to go out, although 50s shouldn't be that scared in this example.

I blame lack of excersize, junk food as BORED and beer most likely, LOADS and LOADS 5x's normal heart attack call outs this week, been rushed off there feet with them.

i keep feeling crap, eating too much crap, type 2 diabetes not far away, got to get back off the sugar, doing a lot of hill walking and bike riding to compensate, but still, need to behave :(
