Overview

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.
Substance Use Disorder
Substance use disorder is a medical condition involving continued use of alcohol or drugs despite harmful effects or difficulty controlling use. It can affect health, relationships, work, and daily functioning. The disorder may involve craving, loss of control, increasing tolerance, withdrawal symptoms, or repeated unsuccessful attempts to reduce or stop use.

Diagnosis

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.
Substance Use Disorder
Diagnosis is based on a clinical assessment of substance use and its effects on health and daily functioning. Healthcare professionals consider patterns of use, inability to control use, craving, continued use despite harm, tolerance, withdrawal, and related problems. Screening questionnaires and assessment for medical or psychiatric complications may also be used.

Prevention

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.
Substance Use Disorder
Substance use disorder cannot always be prevented, but risk may be reduced by delaying or avoiding harmful substance use, using prescribed medicines only as directed, building healthy coping strategies, and addressing stress or trauma appropriately. Early recognition of problematic use and timely professional support can help prevent progression and reduce complications.

Risk Factors

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.
Substance Use Disorder
Risk factors include family history of substance use disorder, early exposure to alcohol or drugs, trauma, chronic stress, certain mental health conditions, social environments where substance use is common, and easy access to addictive substances. Risk varies according to the substance, pattern of use, individual vulnerability, and social circumstances.
