Diseases Mosquitoes Can Carry and Transmit

Diseases Mosquitoes Can Carry and Transmit

Diseases like malaria and dengue fever are worrying enough before realizing that you can be infected with these diseases after just one bite from a tiny flying insect common to nearly every part of the world. Many mosquito-borne illnesses are confined to certain regions of the world and are rarely spread outside of that designated space due to a mosquito’s limited range. Take a look below to educate yourself on the different types of diseases you can potentially contract from mosquitoes and learn what you can do to prevent this from happening.

What Do I Need to Know About Mosquitoes?

These tiny flying insects are a problem nearly everywhere on earth. There are over 3,000 species worldwide and 176 species present in the United States. Of those 176 mosquito species, there are two that humans are most likely to come into contact with, the Aedes aegypti (Asian tiger mosquito) and Culex pipiens (common house mosquito). These two mosquito species target humans and animals most frequently and pose the biggest threat when it comes to transmitting viruses.

Asian Tiger Mosquito

With a habitat that ranges from North America to Asia and Australia and everywhere in between, perhaps there is no other mosquito so widespread as the Asian Tiger Mosquito. Known for carrying and transmitting diseases as chikungunya, zika, dengue fever, malaria, and yellow fever, this mosquito’s bite can have deadly consequences.

Common House Mosquito

Found on nearly every continent, this mosquito is a nuisance for millions, if not billions, of people. While capable of spreading many diseases to a variety of mammals and birds, the common house mosquito is most notable for transmitting West Nile Virus and Eastern Equine Encephalitis to humans.

It’s the Ladies You Have to Worry About

Fun fact: male mosquitoes do not bite. It’s the female mosquitoes that should have you worried. While you can’t go around checking the gender of each mosquito that lands on you, it’s an important bit of information to know. Mosquitoes don’t bite to ingest the blood for food; they actually need it to complete their reproductive cycle.

In fact, mosquitoes can live quite well without ever sucking blood, if a sugary substitute, like nectar, is nearby. However, the relatively small amount of amino acids present in nectar isn’t enough for females to produce and lay eggs. For that, blood is needed.

The Most Common Diseases Spread by Mosquitoes

Some are more well known than others, but each poses a serious threat to humans, especially left untreated. Here’s what you need to know about each disease, where you’re most likely to contract them, symptoms, and treatment options.

Malaria

Malaria is a disease caused by a parasite that is spread to humans through the bite of an infected mosquito. Symptoms, such as fever, headaches, and chills, typically begin to appear 10-15 days after a bite. While children are more at risk, anyone can contract this disease and populations of sub-Saharan African countries account for more than 93% of worldwide cases. Each year, several hundred million cases are typically reported worldwide with over 400,000 deaths, most of which occur in Africa due to a lack of medical access.

If left untreated this disease can be fatal, but it is 100% treatable and curable if caught in time. Malarial tablets should be taken as a preventative measure if you are planning on visiting a country known to have cases of this disease. Treatments after the fact are also available with extremely high levels of success.

West Nile Virus

Found in Africa, Europe, the Middle East, West Asia, and North America, the West Nile Virus can cause a severe or fatal neurological disease in humans as well as other animals and birds. The disease first gained notoriety by infecting and killing large numbers of birds across the globe. Human infections are caused by bites from infected mosquitoes where the virus can enter the bloodstream.

An infection does not necessarily mean you will become ill, as 80% of those infected show no symptoms. The remaining 20% of those infected will present with symptoms such as a fever, headache, fatigue, aches, nausea or vomiting, swollen lymph nodes, and occasionally a rash. These symptoms will appear between 3-14 days after a mosquito bite. Luckily, scientists have developed several tests to quickly and effectively diagnose the disease. While there is a vaccine available for infected horses, no vaccine exists for humans. All treatment is aimed at easing symptoms and supporting the body’s natural defenses.

Zika

First identified in Ugandan monkeys in 1947, this disease gained recent scientific interest with outbreaks in South America. Found in Africa, North and South America, Asia, and the Pacific, this disease has traveled far and wide but prefers tropical and subtropical climates. Symptoms are generally mild and present after 3-14 days with fever, a rash, conjunctivitis, muscle or joint pain, fatigue, and headaches.

While the symptoms are mild in adults, there are new indications that may have far worse effects on unborn babies. If a woman contracts Zika during pregnancy, it can trigger conditions such as microencephaly, fetal loss, and preterm birth. Treatment of mild cases involves alleviating pain or nausea of the symptoms. For pregnancy-related cases, it’s essential to contact a physician to determine treatment.

Yellow Fever

Named for the jaundiced appearance of some patients, yellow fever is a viral hemorrhagic disease transmitted by mosquitoes. Found in tropical areas of the world including Africa, and Central and South America, this disease is both widespread and can be highly dangerous, especially in areas with dense mosquito populations.

Symptoms include fever, headache, jaundice, muscle pain, nausea or vomiting, and fatigue. A small percentage of cases develop severe, life-threatening symptoms. Luckily, this disease can be prevented through a highly effective vaccine that provides up to 99% protection against yellow fever without ever needing a booster. Currently, there is no cure for the disease once a person has it, but survival rates increase greatly when the infected person(s) are hospitalized.

Chikungunya

This disease gets its name from the stooped appearance of some of its victims. The disease is mostly confined to Africa, Asia, and the Indian subcontinent, however, outbreaks elsewhere have been known to occur. Severe joint pain is the main symptom of this mosquito-borne illness, although muscle pain, headaches, fatigue, nausea, and a rash are also common.

Most of those infected recover, but recovery times vary from several days to over a year. The debilitating pain does subside but can leave behind residual joint pain. Chikungunya is often confused with dengue fever, leaving some untreated. To date, there is no cure for the disease. All treatments focus on relieving symptoms.

Eastern Equine Encephalitis

While extremely rare, EEE is extremely dangerous and is often fatal. Spread by the bite of a mosquito, this disease causes inflammation of the brain in humans, other mammals, birds, reptiles, and amphibians. In mild cases, the infected person may never have any symptoms or even know they were infected.

In severe cases, brain swelling, seizures, fever, vomiting, disorientation, or comas are possible symptoms. While there is no cure, two-thirds of those infected recover. Treatment is largely focused on making the symptoms less painful and severe.

Dengue

Found in tropical and sub-tropical climates worldwide, this viral disease infects 100-400 million people each year. While cases have been recorded in many different areas, the virus is most common in urban or semi-urban areas. Regular dengue causes mild symptoms that resemble those caused by the flu. On occasion, this virus will develop into severe dengue, which can be potentially fatal.

There is currently no cure for dengue, only treatment that focuses on relieving symptoms. Access to proper medical care reduces the fatality rate of severe dengue to 1%, making recovery rates much better. Medical professionals highly encourage community measures to help keep mosquito populations low.

How to Prevent Catching Mosquito-Borne Diseases

Mosquitos Prevented from Entering a House By a Screen

Preventing diseases takes careful preparation and thought. Use the following tips to minimize your chances of coming into contact with mosquitoes and learn about ways you can keep their populations low to lessen your chances of getting bitten.

  • Use Mosquito Traps Indoors and OutDynaTrap offers a wide variety of highly effective mosquito traps to keep you protected inside and outside. These poison-free insect traps attract and securely hold insects until you’re ready to dispose of them, ensuring you’re less likely to be bitten no matter where you are on your property.
  • Wear Proper Clothing — While it’s tempting to go outside in short-sleeved shirts and shorts in the summer, you are much more likely to be bitten. Opt for lightweight long-sleeved shirts and long pants so less skin is showing for mosquitoes to target.
  • Dispose of Waste — Any debris or objects in your yard that can hold even the tiniest amount of water should be stored or thrown out. Mosquitoes lay their eggs in water, so it’s important to limit the areas they can use to prevent their populations from growing.
  • Landscape Your Property — Are there areas of your yard that hold water for several days after raining or watering? Landscape these to prevent mosquitoes from using them to lay their eggs.
  • Avoid Peak Mosquito Times — Avoid going outside unprotected at dusk when mosquitoes are most active. If you do go outside during this time, avoid areas near water, wear protective clothing, and take precautions by using mosquito traps.
  • Repair Screens — To prevent mosquitoes from entering your home, replace or repair any screens, especially on doors and windows. If left with holes, mosquitoes will have an easy entrance into your home where they can remain active all day and night.
  • Take Precautions When Traveling — Research your destination before arriving to determine which diseases are most common and if you need to get a vaccine or preventative medicines before you travel. Make sure you bring appropriate clothing to minimize your chances of getting bitten.
  • Consult a Doctor About Symptoms — If any symptoms arise, be sure to consult a doctor immediately. The sooner a disease is caught, the higher your chances are of a full, painless recovery.
