Arbovirus data

<strong>Important notes for interpretation</strong> <strong>Factors influencing exposure</strong>: High mosquito numbers do not always lead to an increase in human arbovirus cases. Other factors, such as weather, human behaviour, and the use of protective measures, can affect the risk of exposure to mosquito-borne viruses. <strong>Trapping locations</strong>: Locations on maps reflect the mid-point of sites within a broader location, not exact mosquito trap sites (as some trapping sites are located on private properties). <strong>Seasonal variation</strong>: Some locations may consistently experience higher mosquito numbers throughout a season while others may have lower numbers and others may have sudden increases in mosquito numbers at points during the season. There may also be variability in mosquito numbers between seasons. <strong>Positive test results</strong>: For mosquito traps, a detection represents the presence of virus in at least one mosquito in a sample of trapped mosquitoes. For sentinel chickens, a positive test result means that one or more chickens in a flock have tested positive for antibodies directed against a particular virus for the first time, suggesting a newly acquired infection. Infection in chickens gives an indication that there is enough virus to transmit to humans.
