Tartuntataudit are infectious diseases, meaning they are caused by pathogenic microorganisms like bacteria, viruses, fungi, or parasites. These diseases can be transmitted from one person to another, or from animals or the environment to humans. Transmission can occur through various routes, including direct contact, airborne droplets, contaminated food or water, or vectors such as insects.

The spread of infectious diseases is a significant public health concern worldwide. Understanding how these diseases are transmitted is crucial for developing effective prevention and control strategies. These strategies often involve hygiene practices, vaccination, sanitation, and public health measures like quarantine or isolation when necessary.

Common examples of infectious diseases include influenza, the common cold, food poisoning, and more serious conditions like tuberculosis or HIV/AIDS. While many infectious diseases are mild and self-limiting, others can cause severe illness, long-term health problems, or even death. Public health efforts focus on reducing the incidence and impact of these diseases through education, surveillance, and medical interventions. Research into new treatments and vaccines is ongoing to combat emerging and re-emerging infectious diseases.
