Northern Beaches Council has advised residents to take extra precautions against mosquitos after Ross River Virus was detected in mosquitos trapped at Narrabeen Lagoon.

Council partners with NSW Health to trap mosquitoes at key locations on the Beaches, to monitor the numbers and types of mosquitoes present and determine if they are carrying viral infections. Traps are set at Warriewood Wetlands and Deep Creek near the Narrabeen Lagoon trail.

Higher than average rainfall due to La Niña has created the perfect conditions for mosquitos to multiply and have meant numbers are up on previous years.

Ross River Virus is spread by the bite of infected female mosquitoes. Many people who are infected will not develop symptoms. Others will have flu-like symptoms that include fever, chills, headache, joint pain or muscular aches. Sometimes a rash occurs on the body, arms or legs.

Symptoms usually develop about 7-10 days after being bitten by an infected mosquito.

There is currently no vaccine against Ross River virus. You can protect yourself and your family from getting bitten by taking the following steps:

• Always wear long, loose-fitting clothing to minimise skin exposure
• Choose and apply a repellent that contains either Diethyl Toluamide (DEET), Picaridin or oil of lemon eucalyptus (OLE)
• Be aware of peak mosquito times at dawn and dusk
• Keep your yard free of standing water like containers, birdbaths, kids toys, and pot plant trays where the mosquitos can breed.
