China counts 170 virus deaths, new countries find infections

China has raised the death toll to 170 and more countries reported infections from a new virus, including some spread locally. Russia announced it was closing its 2,600-mile border with China, joining Mongolia and North Korea in barring crossings to guard against a new viral outbreak. Foreign evacuees from China’s worst-hit region were returning home to medical tests and even isolation. India and the Philippines reported their first cases, and South Korea confirmed a case that was spread locally. Experts worry such cases may mean the virus is spreading more easily. In Geneva, the World Health Organization convened a committee to assess whether the outbreak warrants being declared a global emergency.
