What happens if the reservoir cannot pass along the infection?
Keep in mind that if the reservoir cannot pass along the infection, or if the portal of entry/exit does not reach a new host, then the chain of infection is broken. That means the infection will be more difficult to contract and spread. Here are ways to help reduce the spread of airborne infections: Control air pressure to ensure ...

The specific links in the chain of infection are: reservoir, infectious agent, susceptible host, portal of entry, mode of transmission and portal of exit. 3 Each link must be present and in sequential order for an infection to occur.
How are infectious droplets transmitted?
Infectious droplets are generated during coughing, sneezing, talking and through procedures such as bronchoscopy and suctioning. Transmission occurs when these droplets are propelled a short distance through the air and deposited on a host's mouth, nasal mucosa or conjunctivae. Droplet transmission is not to be confused with airborne transmission because droplets do not remain suspended in the air and special air handling and ventilation is not required.
Why are subclinical cases less likely to be recognized than acute clinical cases?
Subclinical cases and carriers are less likely to be recognized than acute clinical cases because they may not be ill or may maintain activities at a normal level. Precautionary measures such as barrier precautions are less likely to be instituted because the illness is not apparent.
What are some examples of airborne transmission?
Microorganisms transmitted in this manner can be inhaled by a susceptible host, so special air handling is indicated to prevent the spread of infection. Smallpox and Mycobacterium tuberculosis are a few examples of bacteria spread by airborne transmission.
What are the sources of microorganisms?
Human sources of microorganisms are healthcare workers (HCWs), patients and visitors, any of whom may be individuals in the incubation period of a disease, those who already have a disease, or those who are considered to be chronic carriers of an infectious agent. Other sources of bacteria are the patient's endogenous (produced or originating from a cell or organism) flora and inanimate objects that have become contaminated (see next month's issue of Infection Control Today for an article on fomites).
What are the two modes of contact transmission?
Two modes of contact transmission exist, direct-contact transmission and indirect-contact transmission. Direct-contact transmission, as its name implies, consist of direct body surface to body surface contact and physical transfer of bacteria between a susceptible host and an infected or colonized individual.
How many steps are there in the chain of infection?
There are six steps in the chain of infection and transmission will only take place if all six links are intact. Infectious Agent – microorganism (e.g. virus, bacteria, or fungi) Reservoir (source) – a host which allows the microorganism to live, and possibly grow, and multiply. Humans, animals and the environment can all be reservoirs ...
