which link in the chain of infection do standard precautions break?

No matter the germ, there are 6 points at which the chain can be broken and a germ can be stopped from infecting others. The 6 points include: the infectious agent, reservoir, portal of exit, means of transmission, portal of entry, and susceptible host.

Droplet precautions are necessary when a patient infected with a pathogen, such as influenza, is within three to six feet of the patient. Infections are transmittable through air droplets by coughing, sneezing, talking, and close contact with an infected patient's breathing.

⇒ As a general rule, it would seem that omissions of a third party cannot break the chain of causation. For example, if you stabbed someone and a medic arrived but refused to treat the victim, the medic's omission (to treat the victim) would not break the chain of causation.

Carefully clean hospital rooms and medical equipment. Use Contact Precautions when caring for patients with MRSA (colonized, or carrying, and infected). Contact Precautions mean: Whenever possible, patients with MRSA will have a single room or will share a room only with someone else who also has MRSA.

6. True False Bloodborne infections can be transmitted through an open cut or through common skin conditions like dermatitis.

Direct transmission requires close association with the infected host, but not necessarily physical contact. Indirect transmission requires a vector, such as an animal or insect. The link can be broken through hand washing, safe sex practices, or avoiding contact with infected individuals.

aimed at controlling and preventing the spread of infection. There are two types of isolation – Source Isolation (barrier nursing) where the patient is the source of infection and Protective Isolation (reverse barrier nursing) where the patient requires protection i.e. they are immunocompromised.

Standard precautions are the minimum infection prevention and control practices that must be used at all times for all patients in all situations. • Transmission-based precautions are used when standard precautions alone are not sufficient to prevent the spread of an infectious agent.

Break the chain by cleaning your hands frequently, staying up to date on your vaccines (including the flu shot), covering coughs and sneezes and staying home when sick, following the rules for standard and contact isolation, using personal protective equipment the right way, cleaning and disinfecting the environment, ...

MRSA remains a concern in hospitals, where it can attack those most vulnerable — older adults and people with weakened immune systems. Having an invasive medical device. Medical tubing — such as intravenous lines or urinary catheters — can provide a pathway for MRSA to travel into your body.

The link can be broken through hand washing, safe sex practices, or avoiding contact with infected individuals. Link number five is the portal of entry. Entry of the pathogen can take place in one of three ways: penetration, inhalation, or ingestion.

A staph infection is contagious if the wound is weeping or draining and if people share towels or other items that are contaminated.

Bloodborne pathogens can be transmitted through: Accidental punctures and cuts with contaminated sharp materials (e.g. Needle stick). Contact between mucous membranes or broken skin and infected body fluids (e.g. Splash). Sharing of needles.

The skin, mucous membranes, and endothelia throughout the body serve as physical barriers that prevent microbes from reaching potential sites of infection. Tight cell junctions in these tissues prevent microbes from passing through.

The final link in the chain of infection is a susceptible host. Susceptibility of a host depends on genetic or constitutional factors, specific immunity, and nonspecific factors that affect an individual's ability to resist infection or to limit pathogenicity.

Breaking the chain (or novus actus interveniens, literally new intervening act) refers in English law to the idea that causal connections are deemed to finish.

"Universal precautions are mandated for home health agencies but the type of pathogens that exist today require standard precautions that protect staff and patients against more threats of infection than universal precautions," says Barbara B.
