Ramaswami: India, too, has banned flights from more than 30 countries until April 15. However, as data shows and according to the World Health Organisation, travel bans do not always work. Even though China has not banned travel from any countries, the number of new cases has declined drastically over time. This was possible only by enforcing strict monitoring at airports. In places like Shandong in North East China, which saw a large number of flights from South Korea, which was also badly affected, the authorities enforced stringent isolation policy, with dedicated buses transporting travellers to quarantine sites. Travellers from Italy, Japan, the US, and other high-risk countries are also being quarantined.
