HONG KONG (BLOOMBERG) - The sudden re-emergence of Covid-19 in places with the world s best records for handling the pandemic is sending a discouraging message to health officials: Strategies to fully snuff out the virus don t work as a long-term solution, and even the most successful places can never let down their guard.
On the same day, Thailand saw 427 new cases, a staggering jump for a country that as recently as September had gone 100 days without a domestic infection. Unfortunately, in countries that have got really low levels of virus and may well have eliminated it, it s so easy to come back, said professor Peter Collignon, a clinical medicine expert at the Australian National University Medical School in Canberra who has advised the country on virus mitigation.
