Overview
Lactose Intolerance
Lactose intolerance occurs when the small intestine does not produce enough lactase, the enzyme needed to digest lactose, the natural sugar in milk. Undigested lactose passes into the large intestine, where bacteria break it down and produce gas and other substances that can cause symptoms. Typical symptoms include bloating, abdominal discomfort, gas, and diarrhea after consuming lactose-containing foods. The severity varies between individuals and depends partly on the amount of lactose consumed and the degree of lactase deficiency.
Avian Influenza
Avian influenza is an infection caused by influenza A viruses that primarily affect birds but can occasionally infect humans and other animals. Human infections are uncommon but can sometimes cause severe respiratory illness. Most human infections occur after close or prolonged contact with infected birds, animals, or contaminated environments.

InfectionDiagnosis
Lactose Intolerance
Diagnosis is based on the relationship between lactose consumption and digestive symptoms. A healthcare professional may review dietary history and may recommend a temporary reduction in lactose followed by controlled reintroduction. A hydrogen breath test can help confirm lactose malabsorption by measuring hydrogen produced after lactose is consumed. Other gastrointestinal conditions may cause similar symptoms, so persistent or severe digestive complaints may require evaluation for alternative diagnoses.
Avian Influenza
Diagnosis of avian influenza requires laboratory testing because symptoms can resemble other respiratory infections. Testing may involve molecular methods such as polymerase chain reaction on respiratory specimens. A detailed history of contact with birds, animals, contaminated environments, and relevant travel or outbreak exposure is important when evaluating possible infection.
Prevention
Lactose Intolerance
Primary lactose intolerance related to genetically determined lactase reduction cannot generally be prevented. Secondary lactose intolerance may improve when the underlying intestinal condition is identified and treated. People who experience symptoms can often reduce discomfort by adjusting the amount and timing of lactose consumed rather than unnecessarily eliminating all dairy foods. Adequate calcium and vitamin D intake should be maintained through tolerated foods or appropriate alternatives, particularly when dairy consumption is reduced.
Avian Influenza
Reducing contact with sick or dead birds and animals, avoiding contaminated environments, using appropriate protective equipment when exposure cannot be avoided, and practicing good hand hygiene can reduce risk. People working with poultry or infected animals should follow public-health and occupational infection-control guidance.
Risk Factors
Lactose Intolerance
Risk depends on the underlying type of lactose intolerance. Primary lactase reduction is common with increasing age in many populations. Secondary deficiency may occur after intestinal infections, inflammatory disorders, or other conditions that affect the small intestinal lining. Genetic background also influences lactase persistence into adulthood. The amount of lactose consumed, the food in which it occurs, and individual digestive tolerance affect whether symptoms develop.
Avian Influenza
Risk is mainly associated with close or prolonged contact with infected birds or animals, contaminated environments, or surfaces containing infectious material. People working with poultry or other potentially infected animals may have greater exposure. Risk can vary according to the circulating virus and local animal infections.
