"Infected (Contaminated)" refers to a state where an organism, environment, or object has been invaded by harmful microorganisms, such as bacteria, viruses, or parasites. This contamination can lead to diseases or health issues in living beings, and it can also affect the safety of food, water, and surfaces. Infection can occur through various means, including direct contact, airborne transmission, or contaminated surfaces. Common examples include bacterial infections like strep throat, viral infections such as the flu, and foodborne illnesses caused by contaminated food. Proper hygiene and sanitation practices are essential to prevent and control infections.
