Mosquito-Borne Illness: Eastern Equine Encephalitis

As one of the deadliest animals in the world, mosquitoes transmit a number of harmful, and often fatal, diseases. The most well known of these diseases include malaria, Zika virus, and West Nile virus.

In our last Mosquito-borne Illness Spotlight, we focused on malaria, a mosquito-borne illness that causes hundreds of thousands of deaths per year. In addition to these illnesses, mosquitoes are also responsible for transmitting a disease known as Eastern Equine Encephalitis. 

Eastern Equine Encephalitis (EEE) is one of the lesser-known diseases spread by mosquitoes. However, it can be quite serious, often leading to devastating effects. At Mosquito Authority, we make it a priority to educate our customers on not only how to practice mosquito control but also the negative and potentially harmful effects mosquitoes can have.

Here is some basic information about Eastern Equine Encephalitis and steps to prevent mosquito bites in and around your home:

Where does Eastern Equine Encephalitis most often occur?

Mosquitoes can be found all over the world, although only certain species are responsible for EEE. According to the Centers for Disease Control and Prevention (CDC), most cases of EEE in the United States occurred in Massachusetts, Michigan, Florida, Georgia, New York, and North Carolina from 2010-2019. 

What is Eastern Equine Encephalitis?

Eastern Equine Encephalitis is transmitted by mosquitoes of the Aedes, Coquillettidia, and Culex species. Although it is extremely rare, EEE can have very serious symptoms. Symptoms of EEE can range from fever and joint pain to encephalitis (swelling of the brain) and meningitis (swelling of the membranes that surround the brain and spinal cord). According to the CDC, about a third of EEE cases are fatal, while many survivors end up with mild to severe brain damage. 

How is Eastern Equine Encephalitis transmitted?

EEE is transmitted to humans or animals through the bite of an infected mosquito. Similar to malaria, EEE cannot be directly transmitted from person to person. According to the CDC, “Transmission [of EEE] to humans requires mosquito species capable of creating a “bridge” between infected birds and uninfected mammals such as some Aedes, Coquillettidia, and Culex species…”

What precautions can be taken to help prevent mosquito bites around the home?

Taking the proper precautions when it comes to mosquito-proofing your yard and home is critical to mosquito control. Here are some ways you can help lower the risk of getting bitten by mosquitoes in your own outdoor space:

  • To reduce your children’s risk of mosquito bites, dress them in clothing that covers their arms and legs.
  • Always apply sunscreen before applying mosquito repellent.
  • Always be sure to use an EPA-registered mosquito repellent and read the label and instructions thoroughly.
  • Empty any items in your yard that can hold water such as flower pots, tire swings, birdbaths, and children’s toys.
  • Keep patio or outside doors closed when possible to keep mosquitoes outside.
  • Hire a professional mosquito control company

Mosquitoes are not only a nuisance, but they are also vectors for dangerous diseases. While DIY mosquito control is important, the best way to reduce your risk of mosquito bites and mosquito-borne illness at home is to hire a professional mosquito control company. At Mosquito Authority, our priority is ensuring your safety from mosquitoes and the diseases they carry.

Mosquito-Borne Illness: Malaria

It is no secret that mosquitoes are one of the most bothersome pests on the planet. In addition to invading your outdoor space and ruining your summer fun, mosquitoes are also the deadliest creatures in the world. According to the American Mosquito Control Association, over 1 million people die worldwide from mosquito bites every year. These insects are vectors for a number of diseases such as dengue, Zika, West Nile virus, Yellow fever, and malaria. 

In our last mosquito-borne illness spotlight, we discussed Zika virus. This week we are introducing you to probably the most well-known and deadly mosquito-borne illness in the world– malaria. 

As mosquito control professionals, we want our customers to have all the facts when it comes to these pests and their potential health risks. Here are some commonly-asked questions about malaria and information on how to prevent mosquito bites around your home:

Where are mosquitoes found?

Most people become infected with malaria from the bite of an Anopheles mosquito. Members of this species typically inhabit tropical and subtropical areas of the world, according to the Centers for Disease Control and Prevention. This is why malaria outbreaks are common in places such as Africa, Asia, and South America.

What is malaria?

Malaria is caused by a parasite that infects Anopheles mosquitoes. According to the CDC, there are four types of malaria parasites that infect humans: Plasmodium falciparum, P. vivax, P. ovale, and P. malariae. Symptoms of malaria typically include high fever, chills, and other flu-like symptoms.  

How is malaria transmitted?

Anopheles mosquitoes become infected with malaria by taking a blood meal from a previously-infected person. When an infected mosquito takes its next blood meal, the parasites within its saliva are injected into the host. Malaria is not contagious; a person must be bitten by an infected mosquito to contract the disease.

What precautions can be taken to help prevent mosquito bites?

Part of thorough mosquito control is knowing how you can prevent mosquito bites from occurring in your outdoor space. Here are some tips on how you can reduce your risk of being bitten by mosquitoes around your home and outdoor area:

  • Get rid of standing water in your yard. This includes changing the water in birdbaths and emptying items such as trash can lids, tire swings, and toys of water that has collected.
  •  Try to reduce your outdoor activity during the hours of dusk and dawn, which is when mosquitoes are most active.
  • Wear insect repellent containing DEET, picaridin, or oil of lemon eucalyptus when spending time outside.
  • Use EPA-registered insect repellent products.
  • Keep windows and doors closed to avoid letting mosquitoes in your home.
  • Hire a local mosquito control company.

Mosquitoes are much more than annoying insects. In many areas of the world, they transmit serious and often deadly diseases like malaria.

Mosquito-Borne Illness: West Nile Virus

Mosquitoes are known for being a highly bothersome pest, invading your backyard and preventing you from enjoying the outdoors. But did you know they are also the deadliest insect in the world? By transmitting diseases such as malaria and dengue fever, mosquitoes cause hundreds of thousands of deaths worldwide every year. One of those diseases carried and transmitted by mosquitoes is West Nile virus. 

As a mosquito control company, our main goal is to protect you and your family from mosquito-borne illnesses so you can feel free to enjoy the outdoors with peace of mind. Here are some commonly-asked questions about mosquitoes and West Nile virus along with some helpful information from the National Pest Management Alliance (NPMA):

Why are mosquitoes considered a dangerous pest?

Although most Americans think of mosquitoes as just a nuisance, they are much more than that. Mosquitoes are notorious for spreading several potentially deadly diseases to humans and animals, including West Nile Virus, malaria, dengue fever, and equine encephalitis. According to the NPMA, more than 700,000 children die each year from malaria in Africa.

Should the average American be concerned about contracting West Nile virus?

West Nile virus has continued to spread throughout the United States since 1999. According to the Centers for Disease Control and Prevention, West Nile virus is the leading cause of mosquito-borne illness in the United States. Most people infected with West Nile virus do not experience serious symptoms, while others can die from the disease. In order to reduce your chance of being bitten by an infected mosquito, wear long pants and long-sleeved shirts while outside when appropriate.

Are mosquitoes more prevalent during a specific season?

Yes, mosquitoes are most prevalent during the summer months. However, depending on the region and temperature, mosquitoes can also be active during the fall. Mosquitoes typically remain active until temperatures drop below 60 degrees.

Does the weather have an impact on the spread of West Nile virus?

Since mosquitoes thrive in high temperatures, they are more active in the warmer months. According to the NPMA, extreme heat and drought conditions might play a part in the spread of this virus. When the weather warms up, mosquito larva grows more quickly and the breeding cycle speeds up.

What are the symptoms of West Nile virus?

Symptoms of West Nile virus are typically mild and usually mimic those of the flu. However, some severe cases can lead to a potentially fatal infection causing fever, body aches, weakness, confusion, and sometimes coma.

How can I prevent West Nile Virus?

There are several precautions you can take in order to protect yourself and your family from mosquitoes and mosquito-borne illnesses like West Nile virus. Here are some tips from the NPMA:

  • Eliminate mosquito breeding sites around your yard and home by getting rid of all standing water. Common items that tend to collect standing water include grill covers, trash cans, birdbaths, tire swings, and more.
  • Screen windows, doors, and other openings in your house with mesh.
  • Minimize outdoor activity during dusk and dawn, which is when mosquitoes are most active.
  • Use insect repellent containing DEET, picaridin, or oil of lemon-eucalyptus on exposed skin.
  • Contact a local mosquito control company
