Virus infections continue to rise in South Korea

SEOUL, SOUTH KOREA — South Korea reported an eight-fold jump in viral infections Saturday with more than 400 cases mostly linked to a church and a hospital, while the death toll in Iran climbed to five and a dozen towns in Italy effectively went into lockdowns as health officials around the world battle a new virus that has spread from China.

Some virus clusters have shown no direct link to travel to China. The secondary contagions in Italy prompted local authorities in the Lombardy and Veneto regions to order schools, businesses, and restaurants closed and to cancel sporting events and Masses. Hundreds of residents and workers who came into contact with an estimated 54 people confirmed infected in Italy were in isolation pending test results. Two people infected with the virus have died.

South Korea has reported 433 cases and its third death from the virus, a man in his 40s who was found dead at home and posthumously tested positive. There’s concern that the country’s death toll could grow. In and around South Korea’s fourth-largest city, Daegu, health workers scrambled to screen thousands.

Globally, nearly 78,000 people have been infected in 29 countries, and more than 2,300 have died.

A team of global experts with the World Health Organization is on the way to China’s Wuhan, the epicenter of the outbreak, WHO Director-General Tedros Adhanom Ghebreyesus said Saturday. It has been visiting other parts of China this past week.
