In May, the Interim Australian Centre for Disease Control issued a Media release advising that a human case of avian influenza (H5N1) has been detected in Australia (Victoria), this is the first human case ever recorded in Australia. A child acquired the infection while overseas and became unwell on returning to Australia earlier this year. Importantly, the case in Victoria is not the same as the strains that have recently been found in dairy cattle in the USA. It is also not the same strain that has been detected at a poultry farm in Victoria. Australia’s interim Centre for Disease Control (CDC) is monitoring the risks to the Australian public

In early January 2024, a media release was issued for people who had been in the Sydney CBD to be on alert for symptoms of Legionnaires disease as a number of people had developed the disease after spending time in the area.
ACIPC CONFERENCE
Respiratory viruses cause illnesses that affect the nose, throat and breathing passages including the lungs. These viruses commonly result in mild cold or flu like symptoms in most people, except in those with risk factors, the elderly and the very young.
Infectiousness. Most patients are usually most infectious in the first few days that they have symptoms. However, sometimes people are infectious a few days before their symptoms start. While they continue to have a fever or generally feel unwell, you are still infectious. Some people, particularly those who are immunosuppressed, can remain infectious after they have recovered from their illness.

Recommendations
Clinicians should be aware of compatible clinical presentations in travellers returning from an endemic area or affected countries. Information on recent travel history, contacts and immunisation should be elicited.
Clinicians should consider the possibility of monkeypox as well as alternative diagnoses such as measles, varicella zoster, Herpes Simplex and Varicella Zoster Virus infections, and syphilis. Notify any suspect cases to the Department of Health / Public Health Unit.
Timely contact tracing and surveillance measures are essential to prevent secondary cases. Vaccination may be offered to close contacts within 4 days of exposure.
HCWs caring for suspected or confirmed patients should implement both standard contact and airborne precautions.
As we are entering a post lockdown COVID era, with surgery and admissions returning to normal – it is a good reminder to refocus on re-emergence of healthcare acquired infections and prevention of same especially Influenza and other Respiratory infections.
All Patients are potentially at risk of acquiring, and transmitting, infectious conditions to other patients and healthcare workers. Patients should be assessed on, and during admission, to ensure that their bed allocation is both appropriate and timely. Patient placement is an important element of transmission-based precautions, along with the use of dedicated equipment, the use of appropriate PPE, and effective environmental cleaning.
Patient placement is a two-step process that is informed by a risk assessment (Step 1) followed by prioritisation of the seriousness of the infection and any competing patient needs (Step 2). Collaboration with the IPC service should be sought as soon as possible.
Step 1: Risk Assessment
The placement of patients in any clinical area should be considered, and risk assessed according to a number of factors, including, but not limited to:
Step 2: Prioritisation
The prioritisation of single room isolation, or other arrangements when a single room is not available, is not just dependent on the mode of transmission and infectivity of the pathogen, but also on the seriousness of the infection to other individuals.
Single rooms are preferred for all patients requiring isolation due to infectious conditions, and are always indicated for patients requiring airborne precautions (ideally with negative pressure ventilation). Designated bathroom facilities should be available, the door must be kept closed and appropriate signage displayed outside the room. Consideration of competing needs must also be taken into account, such as patients requiring end-of-life care; those who are immunosuppressed; patients with a higher need for privacy and dignity; or those requiring reduction of harm afforded by a single room.
The Commission has developed a Guide to support nurses, doctors, bed managers, patient flow managers and after-hours managers in the appropriate bed allocation.
Standardised infection control signage complements good patient placement by increasing the awareness of healthcare workers, patients and visitors to the necessary precautions required.
What is Japanese Encephalitis: Japanese encephalitis (JE) is a rare but serious disease caused by the Japanese encephalitis virus (JEV). It is spread to humans by infected mosquitoes.
Symptoms: Less than 1% of people infected with JEV will experience symptoms. Some infected people experience an illness with fever and headache. People with a severe infection may experience neck stiffness, disorientation, tremors, coma, and seizures. If you have any of these symptoms, seek medical treatment. Among those who develop severe infection, some will go on to experience permanent neurological complications or possibly death. Symptoms, if they are to occur, usually develop 5 to 15 days after being bitten by infected mosquitoes.
Transmission: JE is spread by the bite of infected Culex species mosquitoes which are commonly found in NSW. Culex mosquitoes can become infected with JEV from biting infected animals. The virus is spread when mosquitoes bite an infected animal, and the mosquito then bites a human. Infected pigs and some waterbirds are the animals more likely to infect mosquitoes. Humans are not able to pass JEV to other humans. Humans cannot get infected with JEV by touching an infected animal or eating animal products including pork or poultry products.
Who is at Risk? JEV has recently been identified in commercial piggeries in locations in NSW, Queensland, Victoria and South Australia. Local infection risks are likely highest among:
JEV is endemic in much of Asia and parts of the Pacific. For most travellers in these regions, the risk of being infected with JEV is very low. People at the greatest risk of becoming infected are those who are staying more than a month in rural areas in countries where the disease is endemic or in some of the Torres Strait Islands.
Prevention: AVOID MOSQUITO BITES
The mosquitoes that transmit JEV are most active at dawn and dusk and into the evening. Take extra care during peak mosquito biting hours, avoid the outdoors if possible or take preventive actions.
Personal protection measures
Treatment: There is no specific treatment available for JEV. The best way to avoid infection is to avoid being bitten by mosquitoes.
Vaccination: A safe and effective vaccine for JEV is available for people aged 2 months and older. Vaccination against JEV is currently only recommended for those at highest risk of infection.
Refer to State Health Alerts for further information.
Latest ATAGI / Govt. recommendations 24/1/22
Past Infection:
People with a past SARS-CoV-2 infection. Past infection is not a contraindication to vaccination. People with SARS-CoV-2 infection can be vaccinated as soon as they have recovered from their acute illness or can temporarily defer vaccination for up to 4 months after onset of the SARS-CoV-2 infection. ATAGI has decreased the time allowable for deferral of vaccination after prior SARS-CoV-2 infection from 6 months to 4 months, due to the increased risk of re-infection with the Omicron variant, particularly for those who had a Delta variant infection in 2021.
Timing of administration of other vaccines
COVID-19 vaccines can be co-administered (that is, given on the same day) with an influenza vaccine. Studies demonstrate the safety and immunogenicity of co-administration of COVID-19 and influenza vaccines.
COVID-19 vaccines can also be co-administered with other vaccines if required.
This includes routine childhood and adolescent vaccines. The benefits of ensuring timely vaccination and maintaining high vaccine uptake outweigh any potential risks associated with immunogenicity, local adverse reactions or fever. There is limited evidence on the safety and effectiveness of co-administering COVID-19 vaccines at the same time as other vaccines. Providers need to balance the opportunistic need for co-administration with giving the vaccines on separate visits. There is the potential for an increase in mild to moderate adverse events when more than one vaccine is given at the same time.
Booster dose recommendations
A single COVID-19 vaccine booster dose is recommended for people aged ≥16 years who completed their primary course 3 or more months ago.
Pfizer or Moderna COVID-19 vaccines are the preferred vaccines for this booster dose, regardless of which vaccine was used for the primary course. Although not preferred, AstraZeneca can also be used as a booster dose for:
There is a growing body of evidence supporting the safety and effectiveness of Pfizer and Moderna as booster vaccines. Data on the use of AstraZeneca as a booster dose are more limited. (See Vaccine information – clinical guidance)
The recommended interval between completing the primary COVID-19 vaccine course (the second dose for most vaccine brands) and the booster dose is 3 months.
Recommendations regarding COVID -19 Boosters have been released 28/10/21 by the Australian Technical Advisory group on Immunisation (ATAGI). ATAGI advises that, the highest priority groups to receive booster doses are those with risk factors for severe COVID-19 and/or those at increased occupational risk, notably:
To facilitate implementation of the COVID-19 vaccine booster program, ATAGI supports the use of a single booster dose for those who completed their primary COVID-19 vaccine course ≥6 months ago; initially to include, the groups above who were prioritised in the rollout of the vaccine program from early 2021.

There are currently programs in each state that are advocating / reviewing the requirement for fit testing:
Fit-testing measures the effectiveness of the seal between the respirator and the wearer’s face. It is required for all tight-fitting respirators, including:
• half-face disposable
• half-face reusable
• full-face reusable
• tight-fitting powered air purifying respirators (PAPR).
There are two methods of fit-testing that meet AS/ NZS 1715:2009 Selection, use and maintenance of respiratory protective equipment:
• Qualitative – a pass/fail test that relies on the wearer’s ability to taste or smell a test agent. This type of test can only be used on half-face respirators.
• Quantitative – uses specialised equipment to measure how much air leaks into the respirator. This type of test can be used on half-face respirators, full-face respirators and PAPR. Quantitative fit-testing results are more objective than qualitative testing because some workers have difficulty with their ability to taste or smell. This can result in a potential for a false pass to the qualitative fit-test and worker health not being adequately protected. For further information refer to www.standards.org.au and search AS/NZS 1715 and / or state direction / recommendations.

Upper Respiratory Infections: Common cold, Sinusitis Pharyngitis, Epiglottitis and laryngotracheitis: Most are of viral etiology. Epiglottitis and laryngotracheitis are exceptions with severe cases likely caused by Haemophilus influenzae type b. Bacterial pharyngitis is often caused by Streptococcus pyogenes.
Pathogenesis: Organisms gain entry to the respiratory tract by inhalation of droplets and invade the mucosa. Epithelial destruction may ensue, along with redness, edema, hemorrhage and sometimes an exudate.
Clinical Manifestations: Initial symptoms of a cold are runny, stuffy nose and sneezing, usually without fever. Other upper respiratory infections may have fever. Children with epiglottitis may have difficulty in breathing, muffled speech, drooling and stridor. Children with serious laryngotracheitis (croup) may also have tachypnea, stridor and cyanosis.
Microbiologic Diagnosis: Common colds can usually be recognised clinically. Bacterial and viral cultures of throat swab specimens are used for pharyngitis, epiglottitis and laryngotracheitis. Blood cultures are also obtained in cases of epiglottitis.
Prevention and Treatment: Viral infections are treated symptomatically. Streptococcal pharyngitis and epiglottitis caused by H influenzae are treated with antibacterials.
Lower Respiratory Infections: Bronchitis, Bronchiolitis and Pneumonia: Causative agents are viral or bacterial. Viruses cause most cases of bronchitis and bronchiolitis. In community-acquired pneumonias, the most common bacterial agent is Streptococcus pneumoniae. Atypical pneumonias can be caused by Mycoplasma pneumoniae, Chlamydia spp, Legionella, Coxiella burnetti and viruses. Nosocomial pneumonias and pneumonias in immunosuppressed patients have etiology with gram-negative organisms and staphylococci as predominant organisms.
Pathogenesis: Organisms enter the distal airway by inhalation, aspiration or by hematogenous seeding. The pathogen multiplies in or on the epithelium, causing inflammation, increased mucus secretion, and impaired mucociliary function; other lung functions may also be affected. In severe bronchiolitis, inflammation and necrosis of the epithelium may block small airways leading to airway obstruction.
Clinical Manifestations: Symptoms include cough, fever, chest pain, tachypnea and sputum production. Patients with pneumonia may also exhibit non-respiratory symptoms such as confusion, headache, myalgia, abdominal pain, nausea, vomiting and diarrhea.
Microbiologic Diagnosis: Sputum specimens are cultured for bacteria, fungi and viruses. Culture of nasal washings is usually sufficient in infants with bronchiolitis. Fluorescent staining technic can be used for legionellosis. Blood cultures and/or serologic methods are used for viruses, rickettsiae, fungi and many bacteria. Detection of nucleotide fragments specific for the microbial antigen in question by DNA probe or polymerase chain reaction can offer a rapid diagnosis.
Prevention and Treatment: Symptomatic treatment is used for most viral infections. Bacterial pneumonias are treated with antibacterials. A vaccine against 23 serotypes of Streptococcus pneumoniae is recommended for individuals at high risk
