Infectious diseases can be spread through the following agents:

i)      Through air: Cough or sneeze of an infected person may cause infection to a healthy person if he inhales the droplets containing microbes. Diseases like common-cold, tuberculosis, pneumonia, etc., are spread through air.
2)      Through water: Consumption of water contaminated with the spores of bacteria or disease causing microbes can cause diseases like cholera, amoebiasis.
3)      Through sexual contact: Unsafe sexual contact with an infected partner many lead to many sexually transmitted diseases. For example, syphilis, AIDS, genital warts, etc.
4)      Through vectors: Vectors (animals or microorganisms) carry the infecting agents from a sick person to another potential host. They act as a carrier of a disease or infection. Example- Malaria
