You can blame China for making this virus, but not for spreading it. China might have hide it for some time, but everyone got to know about Virus in November. The first case in India was reported in January. All countries should have stopped their flights in November itself. Initially they were concerned about economy, then they were busy in bringing their citizens in their respective country. Just let everyone remain where they are and get treatment if needed. Why do they need to exchange people and make it more complicated?
I don't think anybody knew about the virus in November. I think it was China who came to know about this impeding pandemic in November. They hid the information with tacit/open/unknowing support of WHO . and before Wuhan was put under lockdown almost 5 million people left Wuhan for different parts of the World. If China had acted earlier the pandemic, loss of human life and wealth would have been avoided.
China needs to be punished.
Iran refused to treat Indian citizens in Iran citing the reason that they did not have enough test equipment.
So India had to fly down a medical team to Iran to treat them and get them back.
