Do you trust Iran's figures?
At face value they seem to be doing remarkably well for a country under sanctions. I believe they have got their epidemic under control because they are one of the most monitored places on Earth, and we would know if they had huge problems, and their general population does not give the appearance of being traumatised. They have trouble keeping them off the roads during New year celebrations.
I think Iran has had assistance from China, Russia and the UAE.
It is significant in that this is the first underdeveloped nation which it struck. In China, Asia Pacific, USA, Europe the virus is now on the retreat and attention turns to whether the lockdown measures used so far can be effective in poorer countries. Iran would suggest they can get through it.
