Worst Places in the World for Mosquitoes

With approximately 3,500 known species of mosquitoes and hundreds bred at one time, there are not many places in the world you can escape their presence.  Besides being a general nuisance and causing itchy bites, mosquitoes are dangerous vectors of disease harmful to both humans and livestock.

Mosquitoes are widespread and prefer to live in warm, humid tropical regions. They have spread across the world mainly by humans where they inhabit objects such as water-filled containers like tires or cut flowers and are transported by sea, vehicles, trains or aircraft. Mosquitoes have no respect for international borders, and a mosquito-borne disease can be spread quickly from human to human, causing significant outbreaks.

Each year, viruses transmitted by mosquitoes kill more than a million people, and over a billion are infected causing brain damage, blindness, serious illness, and debilitating pain.  Some of the main and well-known diseases included Dengue Fever, Yellow Fever, Malaria, and the West Nile Virus.

So, Where Are the Worst Places in the World for the Mosquito?

It is believed Brazil, Indonesia, Malaysia, and Thailand have the highest numbers of mosquito species.  Australia, Indonesia, the Philippines, and Brazil are recorded to have the highest number of endemic species.  However, it is the whole of Africa, South America and Asia where most of the mosquito-borne diseases occur.

In Africa, mosquitoes are widespread and difficult to control, particularly in rural areas, villages with poor drainage or highly polluted zones. Today, 90% of all malaria deaths in the world occur in Africa, south of the Sahara.  Malaria is primarily caused by the Plasmodium Falciparum parasite, which is found in high numbers within this region. So if you are thinking of heading off on a safari anytime soon, you will need to get vaccinated and pack a lot of mosquito repellent!

The mosquito-borne tropical disease, Dengue Fever affects the whole of the Americas, Asia, and Africa and is the most rapidly spreading virus by this vector.  Between 50-100 million people contract the virus every year and the numbers are growing.   The virus is not usually fatal, but it is the leading cause of death for children in Latin America and Asia.

If you are planning a hike in the jungle or an exploration of the cities in Africa and South America, you are at risk of contracting the yellow fever virus. Currently, it is considered endemic in 30 African and 13 Central and South American countries.  It is estimated that around 200,000 people each year are infected and 30,000 of those people die from the virus.

The West Nile Virus was first identified in East Africa, but it has since spread widely across the world. The virus is considered to be an endemic pathogen in Australia, Africa, Asia, the Middle East, Europe, and the United States.  In 2012 the virus infiltrated Texas and a record 286 people died as a result.

Mosquitoes have diverse habitats that allow them to colonize different kinds of environments. They thrive in fresh or polluted water, so remote areas where there is poor drainage are a haven for mosquitoes. Generally, they are widespread throughout the tropics and temperate regions, so a pretty large portion of the world.

Keen to Get Away from Mosquitoes?

There are not many places in the world mosquitoes don’t populate.  Antarctica is mosquito free, and new research suggests there are no mosquitoes in Iceland, New Caledonia, the Central Pacific Islands and Seychelles in the Indian Ocean.  Not much choice if you want to escape the worst cities for mosquitos and their itchy bites.

Mosquitoes don’t need much to survive; they travel quickly and are increasingly becoming resistant to commonly used insecticides. Although not all mosquitoes are blood eaters or carry a virus, across the world mosquitoes are viewed as the deadliest of the creatures on earth that carry and cause disease.
