Overview

Concussion
A concussion is a type of mild traumatic brain injury caused by a blow, bump, or jolt to the head or by a force that makes the brain move rapidly within the skull. Symptoms can include headache, dizziness, confusion, difficulty concentrating, memory problems, nausea, sensitivity to light or noise, and changes in sleep or mood. Loss of consciousness is not required.
Influenza
Influenza is a contagious respiratory illness caused by influenza viruses. It commonly develops suddenly and may cause fever, chills, cough, sore throat, muscle aches, headache, and marked fatigue. Some people, particularly young children, may also experience vomiting or diarrhea. Most healthy people recover without serious complications, but influenza can lead to pneumonia and other severe problems in older adults, young children, pregnant people, and individuals with certain chronic conditions or weakened immunity. Seasonal vaccination and appropriate infection-control measures help reduce illness and transmission.

Diagnosis

Concussion
Concussion is diagnosed primarily from the circumstances of the injury, symptoms, and neurological examination. Healthcare professionals assess memory, concentration, balance, coordination, and other neurological functions. CT or MRI is not required for every concussion but may be used when there are signs suggesting a more serious brain injury, such as severe worsening headache, repeated vomiting, seizures, or neurological abnormalities.
Influenza
Influenza can often be diagnosed clinically from symptoms and the pattern of illness during periods of active community transmission. Rapid influenza diagnostic tests may provide results quickly, although their ability to detect infection varies. Molecular tests, including rapid molecular assays and other laboratory methods, can provide more sensitive confirmation when testing is indicated. Testing is particularly useful when the result may affect treatment, infection-control decisions, or evaluation of people at higher risk of complications. The diagnosis should also consider other respiratory infections with similar symptoms.

Prevention

Concussion
Concussion risk can be reduced by using appropriate protective equipment, following sports-safety rules, improving playing and training techniques, using seat belts, preventing falls, and making homes and work areas safer. Helmets can reduce the risk of some head injuries but cannot prevent every concussion. Anyone suspected of having a concussion should stop the activity and be medically assessed before returning to sports or other high-risk activities.
Influenza
Annual influenza vaccination is an important measure for reducing the risk of influenza and its complications. Good hand hygiene, covering coughs and sneezes, improving indoor ventilation, and avoiding close contact with people who are ill can reduce transmission. People with influenza should stay home when sick when possible and follow local guidance about returning to normal activities. Higher-risk individuals should seek medical advice promptly when significant influenza symptoms develop because antiviral treatment may be most useful when started early.

Risk Factors

Concussion
Risk factors include participation in contact or collision sports, activities with a high risk of falls, previous concussion, and situations where protective equipment or safety measures are inadequate. Children and adolescents may require particular attention because their brains are still developing. Returning to activities before recovery can increase the risk of another injury.
Influenza
The risk of influenza is increased during periods when influenza viruses are circulating widely. Older adults, young children, pregnant people, and individuals with chronic heart, lung, kidney, metabolic, or neurological conditions may have a greater risk of serious complications. Weakened immunity can also increase risk. Close contact with infected people, crowded indoor environments, and inadequate ventilation can facilitate transmission. Lack of seasonal vaccination may increase susceptibility to circulating strains.
