U.S. life insurers are trying to curb their own risks to coronavirus by imposing waiting periods for applicants who have traveled to regions with widespread outbreaks, industry experts said.

Life insurers are worried about insuring U.S. customers who have traveled to countries that the U.S. Centers for Disease Control deems most concerning for contagion risk, including China, Iran, and many European nations.

Lincoln Financial Group, on Monday imposed a 30-day waiting period before issuing policies to most applicants who have traveled to those regions, a spokesman said.
