The death on Friday was announced in a statement by Dr. Sherif Ibrahim, regional epidemiologist for the Mid-Ohio Valley Health Department. The department did not disclose the woman’s identity.
Ibrahim said pregnancy increases susceptibility to H1N1 influenza, more commonly referred to as swine flu.
According to the Centers for Disease Control and Prevention, nearly 6 percent of H1N1 deaths are women who are pregnant.
Health officials encourage pregnant women experiencing flu-like symptoms to immediately contact their physician.
