Until the vaccine comes out, there won't be any "normal" travel. That actually means next year.
Suppose you have no new cases in your country, and all the existing cases have either recovered or sadly resulted in death. But, there are countries in the world where cases are still developing. Would you restore travel back to normal levels? No! You import one case, and the whole cycle will restart.
In late summer/early fall, once airports, border crossings, and ports have been equipped with testing facilities, you might see the path back to normalcy. You might see more extensive health screening than the current security screening.
So, we need to get everyone to recover and see no new cases in any major region in the world (or the cases are very well quarantined - such as Ebola in W Africa). We also need to equip all entry ports with extensive health screening. Either that - or get a vaccine out first.
