Ottawa Public Health using drones to help reduce the risk of West Nile virus

Reducing risk of West Nile virus in Ottawa CTV's Peter Szperling has more on how Ottawa Public Health is using drones to help reduce the risk of West Nile virus.

Like a mosquito, it makes a buzzing noise and flies, but unlike the nuisance insect, it's fighting against the spread of West Nile virus.

A drone capable of carrying up to 25 kilograms of larvicide, targeting mosquitos at the beginning of their life cycle, is one of the new tools being used by Ottawa Public Health.

"The products that we use for treatment are safe for the environment. They are safe for humans and pets," says Alison Samuel with Ottawa Public Health.

"Only if you are a mosquito larvae or a mosquito would you be affected by these products."

The drone is being used in specifically targeted areas where mosquitos congregate, such as storm water management ponds.

So far this year, there has been one confirmed human case in Ottawa, according to the health agency.

While many who acquire the virus may go without symptoms, about 20 to 30 percent of people who do will possibly develop a rash and flu-like symptoms.

Samuel adds that about one per cent of people could have more severe symptoms, including the elderly and those with a weakened immune system.

HOW DO YOU PROTECT YOURSELF?

Not all mosquito bites have the West Nile virus, but there are several ways to lower the risk of transmission.

According to OPH, you can reduce your chance of infection from vector borne illness by doing the following:

Ottawa Public Health is taking steps to prevent exposure to the virus by testing mosquitos for the virus using a trap.

"Once they are trapped, we bring them to our laboratory and we can evaluate if the virus is present in the mosquito," said Richard Trudel, Scientific Advisor with GDG Environment demonstrates.

The health agency is also targeting areas where there is standing water, such as ditches and catch basins as part of its West Nile prevention program.
