As the pandemic expanded its reach, China and South Korea were trying to hold their hard-fought gains. China is quarantining new arrivals, who in recent days have accounted for an increasing number of cases, and South Korea starting Thursday will increase screenings of all overseas arrivals. The virus causes only mild or moderate symptoms, such as fever and cough, for most people, but severe illness is more likely in the elderly and people with existing health problems.
