SINGAPORE, Dec 20 (Bloomberg): Singapore is investigating 13 cases of Covid-19 infections among people who served their quarantine at a hotel along the city’s Orchard Road shopping strip.
The cases, all imported, had "high genetic similarity” despite the victims arriving from 10 different countries, the government said in a statement on Saturday. Singapore said it conducts whole genome sequencing and phylogenetic analysis on all Covid-19 cases, and it takes about four weeks to culture the virus and complete the sequencing.
