What is quarantine? As more countries are imposing a quarantine on arrivals from 'high-risk' countries.

The World Health Organisation says the Covid-19 quarantine period should not be reduced from 14 days.
The rule currently applies to those who've been diagnosed with the virus, and their close contacts.
Several countries, including France and Ireland, are considering reducing the period to seven or ten days. But Dr Maria Van Kerkhove, from the WHO, says its advice hasn't changed.
