Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, fungi, and parasites. These pathogens can invade the body, multiply, and cause disease by disrupting normal bodily functions or triggering an immune response. Infectious diseases can spread through various modes, including direct contact with an infected person, inhalation of airborne pathogens, transmission through contaminated food or water, vectors like insects, and other routes.
An example of an infectious disease is **influenza**, commonly known as the flu. It is caused by the influenza virus and can spread easily from person to person, particularly in crowded settings. Symptoms typically include fever, cough, sore throat, body aches, and fatigue. Influenza can lead to severe respiratory complications, especially in vulnerable populations such as the elderly or those with underlying health conditions.
