What are the 6 components of the chain of infection?

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.

Why are individuals more vulnerable to infection?

Often, when people age, there is immunosenescence, which means that the immune system doesn’t function as well or as vigorously. The combination of increased comorbid conditions and the decrease in activity of the immune system can make people more prone to infections.

What percent of patients get hospital acquired infections?

Between 5 and 10 percent of all patients contract at least one hospital-acquired infection—also known as a healthcare-associated infection or nosocomial infection—during their stay in an acute care hospital.

Which is the easiest and most important way to prevent infections from spreading?

The most important way to reduce the spread of infections is hand washing – always wash regularly with soap and water. Also important is to get a vaccine for those infections and viruses that have one, when available. See the OSH Answers Hand Washing – Reducing the Risk of Common Infections for more details.

What makes a person a susceptible host?

Factors that increase the susceptibility of a host to the development of a communicable disease are called risk factors. Some risk factors arise from outside the individual – for example, poor personal hygiene, or poor control of reservoirs of infection in the environment.

What are the four ways diseases can spread?

Infectious diseases can spread in a variety of ways: through the air, from direct or indirect contact with another person, soiled objects, skin or mucous membrane, saliva, urine, blood and body secretions, through sexual contact, and through contaminated food and water.

What is the most common method of infection transmission?

Contact transmission is the most common form of transmitting diseases and virus. There are two types of contact transmission: direct and indirect. Direct contact transmission occurs when there is physical contact between an infected person and a susceptible person.

What are the 4 factors that make a person more susceptible to infection?

Life style risk factors such as aging, poor nutrition, infection and exposure to toxicants can also increase susceptibility to illnesses. These life style factors can therefore be considered to cause acquired susceptibility for increased risk for environmental disease.

What factors increase the risk of infection?

Having other medical conditions such as diabetes, chronic obstructive pulmonary disease (COPD), autoimmune disease, among others. If you have other medical conditions, ask your doctor if they put you at increased risk for infection. Other factors, such as poor nutrition, stress, or lack of sleep.

What is the most important risk factor for developing surgical site infections?

A number of risk factors are known to increase the risk for SSIs, including obesity, advanced age, diabetes mellitus, malnutrition, prolonged preoperative stay, infection at a remote site, duration of surgery, surgery technique, presence of drains, inappropriate use of antimicrobial prophylaxis, perioperative …

What is the single most important factor in preventing infection?

Simply put, yes. Hand washing is the single most effective way to prevent the spread of infections. You can spread certain “germs” (a general term for microbes like viruses and bacteria) casually by touching another person.

What diseases are carried in body fluids?

Examples of diseases spread through blood or other body fluids:hepatitis B – blood, saliva, semen and vaginal fluids.hepatitis C – blood.human immunodeficiency virus (HIV) infection – blood, semen and vaginal fluids, breastmilk.cytomegalovirus (CMV) infection – saliva, semen and vaginal fluids, urine, etc.More items…

What are the four main routes for infection to enter the body?

The transmission of microorganisms can be divided into the following five main routes: direct contact, fomites, aerosol (airborne), oral (ingestion), and vectorborne. Some microorganisms can be transmitted by more than one route.

What infections can you catch in hospital?

What is the biggest risk factor for hospital acquired pneumonia?

Risk factors for hospital-acquired pneumonia (HAP) include mechanical ventilation for > 48 h, residence in an ICU, duration of ICU or hospital stay, severity of underlying illness, and presence of comorbidities. Pseudomonas aeruginosa, Staphylococcus aureus, and Enterobacter are the most common causes of HAP.

Who is prone to infections?

pregnant women; infants, and young children particularly under age 2; people of any age with certain chronic health conditions (including asthma or lung disease, heart disease, diabetes, kidney disease or some neurological conditions); people with severely compromised immune systems.

What medication causes weak immune system?

Immunosuppressant drugs are used to treat autoimmune diseases. With an autoimmune disease, the immune system attacks the body’s own tissue. Because immunosuppressant drugs weaken the immune system, they suppress this reaction.

What is the most effective way of preventing cross infection?

And some companies send employees home if they show symptoms of the flu. These measures can significantly reduce the chance of cross infection. Also, washing your hands frequently and thoroughly, and practicing good hygiene, greatly reduces the risk of cross infection.
