Mosquito and West Nile Virus

Top 5 eastern states for West Nile Virus activity


Mosquitoes are a notorious pest and are considered the deadliest creatures on the planet. Although there are larger and more fierce creatures in the world, they do not carry the disease threats mosquitoes do. One of those diseases is the West Nile Virus.

The thing about West Nile Virus is that it is a disease usually carried by birds. However, mosquitoes who get a blood meal from birds can become infected. They then transfer the virus to humans through their saliva. This is how mosquitoes spread a variety of diseases to humans across the world.

Which states and their corresponding cities have the most reported cases of West Nile Virus? Ehrlich Pest Control, the experts in mosquito removal and prevention, take a look at the top 5 east coast states with West Nile activity using 2018 data from the Centers for Disease Control and Prevention.

If you have too many mosquitoes around your home, then you need to contact the local experts who can get rid of mosquitoes and prevent them from returning. Reach out to your local Ehrlich Pest Control office today.

5. Virginia

State of Virginia

The state of Virginia has a humid subtropical climate, which is the perfect place for mosquitoes to breed and thrive. Virginia is interesting because it can have extremes of weather from harsh, wintry weather to very hot, humid summers. There can also be very wet storms, even hurricanes, in Virginia, which create a lot of standing water. These can create breeding grounds for mosquitoes, which is the perfect recipe for West Nile to thrive.

4. Massachusetts

State of Massachusetts - top east coast states for West Nile Virus activity

Located right on the Atlantic Ocean, the state of Massachusetts is the most populous state in the New England region. The state’s most populous city is Boston and its population density makes for a feast for insects like mosquitoes. Massachusetts has a humid continental climate. This means residents don’t have to worry about mosquitoes during the colder winter months, but the climate in the late spring and summer make it a haven for mosquitoes.

3. Ohio

Ohio is located along the shores of Lake Erie, the least “healthy” of the Great Lakes. The biggest city in the state is Columbus in terms of population, but the humid continental climate means cold winters and hot, humid, summers and late spring. The most reports of West Nile virus come from the area of Cleveland, which is located on the banks of Lake Erie and the Cuyahoga River. Mosquitoes thrive in areas where there is a lot of standing water, such as the area of Cleveland and other cities on the lake coast across the state of Ohio.

2. Pennsylvania

Pennsylvania is another state with a humid continental climate. Cold winters followed by very wet, warm springs and then hot summers make the state of Pennsylvania the perfect place for mosquitoes. The city of Philadelphia had the most reported cases of West Nile in 2018. Philadelphia is located on the Delaware and Schuylkill River, as well as a number of smaller lakes. This in conjunction with the humid subtropical climate of hot, muggy summers makes the perfect recipe for mosquitoes. Easy access to food, in terms of human meals, means the virus can easily spread.

1. New York and New Jersey

The highest concentration areas of West Nile Virus in the eastern portion of the country comes from the state of New York but, in particular, the large metropolitan area of New York City. The entire New York City metro area is the most populated in the country. Its location near bodies of water creates the perfect circumstances for mosquitoes to breed. The New York metro area continues into New Jersey, where the highest reports of West Nile come from the areas just across the river from New York City.

What is the West Nile Virus?

West Nile is an RNA virus in the family known as Flaviviridae. This is the same family of viruses that other mosquito diseases originate from including Zika, yellow fever and dengue. The virus is found primarily in birds, but can transfer from birds to people via the saliva of a mosquito.

Most of the time people who are bitten show absolutely no signs of the accompanying West Nile Fever. This is the case with over 80% of those who get the virus. There are some who experience very mild symptoms such as a headache, fever, rash or vomiting. Less than 1% of the population runs the risk of the more severe form of the virus which can turn into encephalitis or meningitis. These are mainly those with weakened immune systems or those over the age of 60.
