Which of the following describes a high-risk group for influenza complications?

• A. Healthy adult
• B. Age 65 and older without comorbidity
• C. Pregnant or postpartum women
• D. Hypertension alone

Answer: (C)

High-risk groups for influenza complications include those with physiologic and immune changes that raise vulnerability to severe illness. Pregnancy brings immune modulation and increased cardiopulmonary demand, which heighten the risk of influenza-related pneumonia, hospitalization, and other serious outcomes. The postpartum period carries similar risks due to ongoing immune shifts and hemodynamic changes. Because of this, pregnant or postpartum individuals are explicitly recognized as high risk and prioritized for vaccination and prompt treatment. By comparison, a healthy adult has lower risk, and hypertension alone isn’t a typical standalone high-risk factor for severe influenza. The combination of immune and physiologic changes during pregnancy makes this group the most clearly high-risk among the options.
