Infection causing microbes travel from patient to person through: 

(i) Air: Sneezing or coughing since little droplets are thrown which they reach another person through air. Example, common Cole, pneumonia etc. 

(ii) Water: contaminated water carries disease causing microbes which cause infection on its usage. Example, diseases such as cholera. 

(iii) Sexual contact: Diseases such as syphilis or AIDS are transmitted by sexual contact from one person to the other. 

(iv) Animals: These are intermediaries, called vectors, transmitting diseases from a patient to the host. Example, mosquitoes (Female Anopheles mosquito) cause spread of malaria.
