Question

What are the different means by which infectious diseases spread?

Answer 1

Infectious diseases generally spread through the direct transfer of viruses, bacteria or other pathogens from one individual to another. This can occur when a person with the virus or bacterium kisses, touches, or sneezes or coughs on someone who isn't affected.

Complete answer:
Infectious disease can spread in different ways. They are as follows:

Through Air: The infected scraps spread by medium s of cough or sneeze of the infected individual which delivers little droplets carrying the microbes. These droplets when breathed by another individual, he/she can get affected by the virus. Eg: Common cold, Pneumonia.
Through water: The vomiting or excreta of an individual suffering from the contagious disease may get associated with the drinking water equipment, ending in the spread of the infection. Eg: Cholera
Physical contact: Contagious diseases such as syphilis, AIDS etc can spread by the medium of sexual contact. AIDS can also be caught through blood transmission and from infected parents to the kid.
Through vectors: Mosquitoes and the bugs work as vectors for the release of several diseases. Eg: Malaria.

Additional Information: Disease-causing microbes can also affect you via spoiled water and food. This method of carrying allows pathogens to spread to many individuals through a single reference. For example, Escherichia coli, is a bacterium that exists in or on specific foods — such as unpasteurized fruit juice or undercooked hamburger.
