Question

which are various media of spreading the infectious disease

Answer 1

Not all infectious diseases are contagious. For example, urinary tract infections, otitis media (inner ear infection), and tooth abscesses don’t spread. On the other hand, some infections, like tuberculosis, influenza, and the common cold are spread by a cough or sneeze from the infected person to other people nearby. Insect bites spread malaria and a dog bite can cause rabies. Drinking contaminated water can cause cholera and eating contaminated food can spread typhoid fever and hepatitis A. Touching a contaminated object or surface can allow the transmission of staphylococcal infections and Ebola virus. Tetanus and many other bacterial infections are acquired by penetrating wounds of the skin. Swimming in infected water can transmit bacterial and parasitic infections. Sexually transmitted infections are spread person-to-person through sexual contact; bacteria ( gonorrhea and syphilis, for example) and viruses (herpes and human papilloma virus) are transmitted through the genital tract. There are many more examples of contagious diseases, but the major modes of transmission are inhalation, ingestion, or penetration through the skin or body openings.
