A mosquito-borne virus has been detected at the Narrabeen Lagoon prompting the NSW Ministry of Health to issue an advisory for locals enjoying their outdoor activities within this Northern Beaches site to protect themselves against the Barmah Forest virus. 

Nature enthusiasts visiting the Narrabeen Lagoon are encouraged to cover up properly and wear light-coloured clothes. They must also use an effective insect repellent and re-apply this every few hours if they have exposed skin. The effectiveness of mosquito repellants usually wears off with perspiration. 



Narrabeen Lagoon is an ideal site for bushwalking, jogging, cycling, fishing and kayaking. There is also a small protected beach by the lake’s entrance, where families enjoy swimming or a picnic.

If the locals are bringing their babies and children for outdoor walks or play, their exposed skin must be protected as well. According to the health officials, repellants are safe for babies above three months but parents are advised to read the labels carefully for the products they use.

The Barmah Forest virus, named after a northern Victorian region where it was first detected in 1974, can cause joint pain and usually develop after seven to 10 days of exposure. Most people recover from the disease. 

“These infections can cause symptoms including tiredness, rash, fever, and sore and swollen joints,” Dr Michael Staff, Director, Northern Sydney Local Health District Public Health Unit said

“The symptoms usually resolve after several days, but some people may experience these symptoms for weeks or even months.”



Mr Staff also said that mosquitoes are more active during the “early and late parts of the day” so he recommends extra protection for locals going to the lagoon at these times. 

“Preventing infection with these viruses depends on avoiding mosquito bites, especially as the mosquitoes have become active after recent rain, warm days and high tides,” Mr Staff added.
