When will international travel normalise, if at all?

In the residential complex where I live, the gates are closed at all times. With the exception of very specific outsiders, no one else is allowed to come into the complex. Not even guests of residents, not even domestic help or drivers.

The theory simply is that we as a residential complex, under these lockdown conditions, have managed to keep Covid-19 out so far, and we would not like to take the risk of an outsider coming in and infecting even one person with the virus, further resulting in a wider spread of the outbreak in our complex.

So fundamentally, we are talking of borders that remain closed!
