S. Korean COVID deaths rise, hope rests on high booster rate

South Korea reported its highest number of COVID-19 deaths in a month Tuesday as U.S. health authorities advised Americans to avoid traveling to the country grappling with a fast-developing omicron surge. The 61 deaths reported by the Korea Disease Control and Prevention Agency on Tuesday was the highest daily tally since the 74 reported on Jan. 19, when the country was emerging from an outbreak driven by the delta variant. While omicron so far seems less likely to cause serious illness or death, the greater scale of the outbreak is fueling concerns that hospitalizations and fatalities could spike in coming weeks.
