Its been more than 2 weeks in places like Italy and Spain, slightly less than that in the UK, it started 23 March but distancing was already in place, public gatherings limited and so on.
Prepare yourself for this to go on for months. Indias lockdown has been a farce. It was begun with 4 hours notice and tens or hundreds of millions of people are now walking up to 600km to get home (to rural areas) from the cities where they were daily paid workers. So they are essentially spreading it through the country step by step if they have it.
Places like South Africa have had a lockdown for a few days but if the virus gets into a township social distancing is impossible. The breakdown of law and order is also a distinct possibility there, they struggle enough as it it.
Nigeria, Africas most populous nation is starting a lockdown in Lagos tonight, (21 million people). It's also extremely densely populated. Then we have places like Bangladesh, Indias neigbour, poor as fuck, people packed and stacked in close proximity.
All of the "third world" countries I mentioned will not have good testing regimes in place and they all get crawled over by Chinese who are providing infrastructure in exchange for raping the continent of its natural resources.
