Antimicrobial Efficacy Antimicrobial efficacy is the rate in which microbes, such as harmful bacteria, are destroyed by antimicrobial agents. Products with kill log rates are typically illustrated on a logarithmic scale from 90% to 99.99999%, with each level separated by multiples of ten. When compared by this scale, users cannot see the whole picture of …
Bacterial endospores exist solely to help low G and C Gram-positive organisms, such as Bacillus, Clostridium, and Staphylococcus species, survive through the most extreme environmental conditions (Ahmad et al, 1999; Cornell University, 2019). Designed with a uniquely formidable cellular structure, bacterial endospores arise during the absence of key nutrients in their environment and play a significant role in protecting …
Disproving the myths on coronavirus Coronavirus, also known as COVID-19 is a new virus which causes respiratory illness. This virus is highly contagious and spreads through droplets of saliva, from person to person. To prevent the spread of infection, one should maintain good hygiene such as regularly washing your hands. Droplets from coughing and sneezing …
Introduction to Aseptic Technique To minimise the risk of infection through the presence of pathogenic microorganisms to patients during clinical procedures, it is critical for healthcare professionals in operating suites to practice aseptic technique (Australasian College for Infection Prevention and Control 2017). As part of the National Safety and Quality Health Service (NSQHS) standard developed …
Standard precautions are the work practices required to achieve a basic level of infection prevention and control. The use of standard precautions aims to minimise, and where possible, eliminate the risk of transmission of infection, particularly those caused by blood-borne viruses. Standard precautions apply to all patients regardless of their diagnosis or presumed infection status. …
Transmission-based precautions (TBPs) are used in addition to Standard Precautions when they alone may be insufficient to prevent the transmission of infections (Health Victoria, 2020). TBPs are used for patients known or suspected to be infected or colonised with epidemiologically important or highly transmissible pathogens that can transmit or cause infection (CDC, 2016). The type …
Understanding how the infection is spread is essential to our efforts to prevent and contain its spread, especially when there is no definitive treatment available. Modes of Transmission There are three modes of transmission: contact, droplet, airborne. Contact Transmission occurs when there is physical contact between an infected person/contaminated object and another person.This can happen …

What is the virus? COVID-19 SARS-CoV-2 is a new coronavirus that emerged in late 2019 and causes the respiratory illness called COVID-19. Many people who contract COVID-19 have mild symptoms while others can become severely ill. While COVID-19 is of concern, it is important to remember that most people displaying symptoms such as fever, cough, …
Healthcare-associated infections (HAIs) continue to trouble the healthcare industry. The Centres for Disease Control and Prevention (CDC) estimates that on any given day, about 1 in 31 hospital patients has at least one healthcare-associated infection (CDC, 2020), while the incidence of HAIs in Australia may be closer to 165,000 per year (Mitchel et al., 2017). …
A sneeze, or sternutation, is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa membrane (Encyclopedia Britannica, 2015). A sneeze expels air forcibly from the mouth and nose in an explosive, spasmodic involuntary action which allows for mucus to escape through …
