Influenza update

Influenza is a highly contagious, viral respiratory tract infection that causes epidemics annually during winter months in temperate zones and periodic worldwide pandemics. It manifests as an acute febrile illness with variable degrees of symptoms and severity, ranging from mild fatigue, fever and cough, to respiratory failure and death. Laboratory testing is available to confirm the diagnosis of influenza. Most patients will recover with supportive care, but specific antiviral therapy is recommended for individuals with underlying medical conditions that place them at high risk for poor outcomes of influenza infection, as well as patients with severe disease. Annually, regular annual influenza vaccination is suggested for all persons aged ≥ 6 months who do not have a contraindication.
