Mosquitoes likely to remain a health hazard this winter

In January 1991 Ross River Fever became a notifiable disease in New South Wales and in that first year the Northern NSW local health district recorded 11 cases.

Up to the end of April in 2020 Northern NSW has recorded 156 cases. Only the Hunter New England local heath district is recording a higher figure at 183 cases.

By contrast Barmah Forest Virus, another notifiable disease, has only been recorded 25 times so far this year.

However, both are mosquito borne infections that are worth doing our best to avoid.

NSW Health advises:

To protect against mosquitoes and reduce the risk of diseases they transmit:

• Cover-up with a loose-fitting long sleeved shirt and long pants when outside
•  Apply mosquito repellent to exposed skin
•  Take special care during peak mosquito biting hours, especially around dawn and dusk
•  Remove potential mosquito breeding sites from around the home and screen windows and doors
•  Take extra precautions when travelling or camping in areas with a higher risk of mosquito-borne diseases.
• For more detailed information on reducing the risk of mosquito bites at home and while travelling see the Mosquitoes are a Health Hazard fact sheet. This also includes more information on mosquito repellents.

As the Australian Bureau of Meteorology is predicting a 70% chance of wetter than average weather from July to September & warmer than average temperatures for coastal New South Wales in June to August this year, it is possible that infected mosquitoes will still be aound this winter so being aware of the mosquito load in your garden is advisable..

At the end of April Stratford Virus was detected in mosquitoes trapped in Yamba at the mouth of the Clarence River. This virus is not notifiable in New South Wales and infection usually presents as a mild fever with associated joint pain and lethagy.
