Mosquito numbers on the rise.

Ideal conditions for heartworm to spread.

Extraordinary numbers of mosquitoes resulting in a record Ross River Virus (RRV) season in NSW and VIC. What is the implication for our pets and heartworm management?

As you may have heard, several reports from NSW and VIC authorities warn about the unusually high number of mosquitoes giving way to an exceptional outbreak of the mosquito borne infectious disease Ross River Fever. There are a number of mosquito species that play a role in the transmission of Ross River virus. Some of these species are the same vectors that carry heartworm larvae. Heavy rainfall and flooding in several states during spring created the perfect environment for mosquito populations to multiply.

Favourable conditions have affected all species of mosquitoes, including those carrying Dirofilaria immitis. The increased number of mosquitoes and the presence of a reservoir such as foxes in suburban areas and untreated dogs may create ideal conditions for heartworm infection to spread. It is very important to stay vigilant. Unfortunately, the impact of this alarming increase in the mosquito population will only be detected 6-7 months after the risk period due to the long pre patent period ofD. immitis.

The risk for heartworm infection may be higher than usual. It is vital that owners remain vigilant during this time.

• Australian Heartworm Advisory Panel (AHAP) recommends year round heartworm prophylaxis for all canines throughout Australia.
• ProHeart® SR-12 remains the heartworm prevention of choice as it combines long term efficacy with the best in class active ingredient-moxidectin.
• The AHAP recommends testing of all dogs that are overdue or given monthly prophylaxis, where doses have been potentially missed. This testing is important due to the extraordinary numbers of mosquitoes of late and the resultant increased risk of heartworm transmission. 

It is extremely important that your dog is up-to-date with heartworm prevention. If you are unsure or to make an appointment please contact the Hospital on the below numbers or sent us an email if it's outside our business hours and we will check your pets history and get back to you.
