Measles prompts total shut-down of Samoa

In the Pacific nation of Samoa, the government closed all schools and businesses this week because of an unprecedented measles outbreak — 4,000 cases in a country of just 200,000. Families that aren’t vaccinated have been encouraged to hang a red cloth on their home, so health workers can more easily find them. The World’s Marco Werman talks with Frances Vulivuli, a medical doctor with UNICEF who has been in Samoa since the start of the epidemic.
