Findings The application of all four social distancing interventions: school closure, workplace
non-attendance, increased case isolation, and community contact reduction is highly effective in
flattening the epidemic curve, reducing the maximum daily case numbers, and lengthening
outbreak duration. These were also found to be effective even after 10 weeks delay from index
case arrivals. The most effective single intervention was found to be increasing case isolation, to
100% of children and 90% of adults.

cold dry air helps SARS2

1. Global fatality rate is 4.34%
2. Italy's fatality rate at 9.3%, Iran 7.8%, Spain at 6.2%, UK at 4.9%, Netherlands at 4.3%, France t 4.2%.
3. 15 of 25 countries with more than 1,000 cases is in Europe (Turkey excluded)
4. U.S. has now the third highest case count globally but fatality rate is well below global average at 1.3%, similar to South Korea at 1.2%.
5. Germany has 5th most coronavirus cases but mortality at 0.4% so far.

"More than 300,000 cases have now been reported @WHO from almost every country on Earth. The pandemic is accelerating."

* It took 67 days from the 1st reported case to reach 100K cases.
* 11 days for the 2nd 100K.
* 4 days for the third 100K.

New data ... found lower rates in kids. But when they relied on contact tracing testing people who come in contact with a confirmed case children seemed to be getting infected at the same rate as adults.

Power of social distancing. Self isolation and self quarantine is the best way to fight the pandemic. Rest keep washing your hands and sanitising yourself and people around you.
