Oh what a problem our air travel is becoming. We have international hub airports in various countries. Once a virus outbreak reaches them, it can be spread to many countries very quickly. Closure of airports seems logical, but it is considered problematic too by governments. However, as a very dangerous virus outbreak spreads exponentially, despite containment efforts, there very soon comes a stage at which you cannot prevent it being spread to other countries unless travel restrictions were imposed earlier. Woe to those who put their trust in princes, the proverb says. It is through prayer and heroics that the folly of governments is sometimes overcome. The prophecy of Joel in the Bible tells of a time when the elect should gather to plead with God for mercy. Jesus said to pray with belief that God will answer.
