Barozi said: Germany saw a decrease of 24% in new infections week over week from 4.7k to 3.6k. Numbers in 14 out of 16 federal states declined but two of them increased by 30-45% which is somewhat concerning. Testing capacity for the past week will be revealed tomorrow. Doubt it will change much. |
Yep this virus is wierd, for some time I thought maybe this virus doesn't spread fast as first thought. But look at Iran, Brazil, Russia, India and Pakistan it's spreading really fast. At the same time things looking good in Germany and Denmark. There must be something random that causes this virus to spread super fast.
And ofc things not looking good in Canada and California, despite ongoing lockdown their cases is just not coming down.

It's actually weird the other way, why is it not spreading faster in India.
The original R0 was estimated at 2.2, and the fastest observed doubling time was 5 days when looking at reported deaths.
Brazil's fastest growth was close to 300% increase week over week (April 1st), 1.17x daily increase, doubling time of 4.5 days which is exactly R0 of 2.2
Brazil slowed down after taking measures, but not enough, and has kept growing between 104% and a spike to 232% week over week, with an average daily growth of 1.042x over the past 30 days, a doubling time of 17 days.
Iran managed to get the growth down from a first peak of 3100 cases per day (March 31st) to a low of 930 cases per day (May 1st) and then turned back into growth, currently adding 2100 cases per day. An average daily increase of 1.036x since the turn around, doubling time just under 20 days.
Russia peaked on May 11th and has been declining since, a slow decline around 90% week over week.
India isn't growing fast either, it's been steadily growing since early March. Currently at about 150% week over week, 1.06x per day, 12 day doubling time. India is just starting to come back down again, slowing down in growth. Over the last month it was 1.048x per day, doubling time just under 15 days.
It's not spreading really fast, but slow exponential growth will still look like that once the numbers start getting big. Brazil, India and Iran all have their own challenges to get below Rt 1.0, and so far they're not succeeding.
Canada or rather Ontario is also back to growth (although today looks better) which is mainly because of people getting too excited about getting back to normal. The heat wave might help. From crowded trails on Saturday, I hardly saw anyone today on my 4 hour bike ride. Traffic on the roads and parking lots was still more than usual :/

Living conditions play a big factor. It is spreading like crazy in Brazil's slums which majority of people don't even have running water. Plus they are packed together. Brazil's president doesn't care for any shutdowns either and social distancing isn't promoted by the government.

They did shutdowns, but not enough, and I doubt it would matter much for the slums.

By March 23rd measures were in effect, which started seeing results from April 1st. (peak growth)
Yet Rt remained above 1.0, not doing enough.
It's a balancing act which accelerates either way. Think of it as interest on daily infections, R0 is about 17% daily interest, Brazil is at 4.2% daily interest. 4 times slower, still going bankrupt.
