As the world worries about spread of the mysterious coronavirus, Springfield is invited to learn about another killer disease, no longer mysterious but potentially as deadly: measles. A September outbreak in Samoa infected 5,000 and killed 81 people, many of them children under 5. "Measles: An International Perspective," the Feb. 4 program of the World Affairs Council of Central Illinois, brings three physicians from the Southern Illinois University School of Medicine to describe global control measures, treatment and prevention, and the history of the anti-vaccination movement. Speakers are Dr. Marcela Rodriguez, Dr. Sana Waqar and Dr. Vidhya Prakash. The 7:30 p.m. program is free and open to the public at the Clubroom, Hoogland Center for the Arts.
