Chain of infection consists of events that occur during the spread of infection starting from multiplication of organism in the reservoir.

It consists of six elements:

1. Organism : the chain of infection starts from organism. For eg. Falciparum plasmodium in malaria

2. Reservoir : reservoir of infection is the living or non living place where the organism grows and reproduce. For eg P falciparum grows in mosquito.

3. Portal of exit : portal of exit is the medium in which the organism grow and enters the host. For eg p. Falciparum grows in saliva of mosquito.

4. Means of transmission : means of transmission is the mode through which the organism enters the host through reservoir. For eg. P. Falciparum spreads enters host through mosquito bite.

5. Portal of entry : how the infection enters the host body. For eg. P. Falciparum enters host through the blood.

6. Vulnerable host : the infected host further spreads the infection. For eg. Infected humans
