Visitors during peak influenza transmission
Host (population)
Risk factor: Age
The total population and the numbers in each age group allows us to calculate the proportion of people of each. Age group in the population, and therefore determine if the population has a high-risk age structure. Two high-risk groups for influenza are children under the age of 5, and people aged 65. And over (REFERENCE). Children under 5 are at both increased risk for transmitting influenza. Increased risk of severe complications and hospitalisations (REFERENCE). People over 65 are at increased risk of severe complications and hospitalisations, due to waning immunity that occurs in older people (REFERENCE).
Suggested control measures are to ensure that people in these age. Groups receive free influenza vaccines as the highest priority (REFERENCE). Children who are symptomatic (LIST SYMPTOMS AND REFERENCE) should be excluded from school/daycare until these have resolved for at least 24 hours (REFERENCE). Residential care facilities may implement restrictions on visitors during peak influenza transmission, to avoid outbreak among residents (REFERENCE).
Risk factor: Aboriginality
The number of Aboriginal residents….

Introduction
This document contains surveillance case definitions for all nationally notifiable infectious diseases as endorsed by the Communicable Diseases Network Australia (CDNA), as well as for eleven infectious diseases or related conditions that are notifiable in Western Australia but not nationally. These latter diseases or conditions include: acute rheumatic fever/rheumatic heart disease, acute post-streptococcal glomerulonephritis (APSGN), amoebic meningoencephalitis, chancroid, carbapenem- resistant Enterobacteriaceae (CRE), melioidosis, Hendra virus infection, methicillin- resistant staphylococcus aureus (MRSA) infection, typhus/rickettsial infection, Vibrio parahaemolyticus infection, vancomycin-resistant enterococci (VRE) and Yersinia infection.
The national case definitions are reviewed or developed for various reasons, for example, to reflect new diagnostic tests or to recognise emerging infections. The most
current version of the national notifiable disease case definitions can be found at:
Several of the nationally notifiable diseases include WA-specific explanatory notes to facilitate case classification (eg. Barmah Forest virus infection, chlamydial infection,
gonococcal infection, legionellosis and Ross River virus infection).APA
