dễ lây lan
/kənˈteɪdʒəs//kənˈteɪdʒəs/The word "contagious" originated from the Latin word "contagiosus," which literally translates to "touchable." This term was used during ancient times to describe diseases that could be transmitted through contact, as the disease seemed to "touch" or affect the person coming in contact with the infected individual. The concept of contagious diseases became more widely understood during the 19th century, as scientists such as Louis Pasteur and Joseph Lister conducted research on the spread of diseases through contact with infected individuals or materials. The term "contagious" came to be associated with diseases that were transmitted through contact, such as cholera, tuberculosis, and smallpox. Today, the term "contagious" is commonly used to refer to infectious diseases that have the potential to spread rapidly from person to person through direct or indirect contact, respiratory droplets, or contaminated objects. Some examples of contagious diseases include the common cold, influenza, measles, and COVID-19. The importance of measures such as social distancing, hand washing, and wearing masks is emphasized to prevent the spread of contagious diseases as a result of their contagious nature.
