West Nile Virus, What to Expect

Media from up and down the east coast and Midwest are reporting the presence of West Nile in mosquitoes and humans. As a result of last year’s record numbers, many municipalities raised their testing and mosquito misting budgets to help combat the mosquito-borne disease, but what can we expect in the coming weeks?

Mosquitoes are out in full force right now. Many areas of the country had periods of heavy rainfall followed by hot weather, the perfect combination for mosquitoes. States like Georgia are reporting a higher number of mosquitoes this year as compared to last year.

West Nile Virus is transmitted through the bite of an infected mosquito, but the victim may not display symptoms for a few weeks after the bite. Typically August is the worst month for West Nile Virus reports. Many of victims probably got the virus in July or even earlier. As more and more cities and towns, from Louisiana to Wisconsin to Massachusetts, report their first human West Nile case of 2013, the numbers are expected to rise in the coming weeks.

Eighty percent of people with West Nile virus will never display symptoms, known as a subclinical case. When symptoms do show, they are flulike, including fever, headaches, aches, nausea, etc. We are often asked what the difference between West Nile Virus and West Nile Fever. West Nile Fever is when patients start to display symptoms. There is currently no vaccine or medications to specifically treat or protect against West Nile, instead, the symptoms themselves are treated.

It is believed that mosquitoes get the West Nile Virus from infected birds that they bite and then pass it along to other animals they get blood meals from. While mammals and reptiles are known to carry the disease, not all have reactions like humans.

The best way to protect against West Nile is to protect against mosquito bites and in a year that the population in many areas is on the rise, that can be difficult. There are things you can do on and off your property to decrease the chance for mosquitoes to bite you.

The first thing to do on your property is to get rid of any standing water. Mosquitoes can lay up to 300 eggs in as little water as a bottle cap, so imagine what they can do in a kiddie pool! Keep kids toys and dog dishes flipped over when they aren’t being used and pay attention to water that is pooling in different areas (like piles of leaves or tarps that aren’t pulled tightly). Getting rid of all the water can be extremely difficult, so consider having professional mosquito control. Mosquito Squad treats its clients’ properties every two to three weeks (depending on package and product) and rids the yard of 85 to 90% of mosquitoes.

Even if you have your yard treated, there will be times when you are off your property and you need to be protected then too. Try to stay inside when mosquitoes are known to be their most active (dawn and dusk). Wearing loose pants and long sleeved shirts make it more difficult for mosquitoes to bite you and you can use a topical mosquito repellent if you need to cover exposed skin.
