Top 5 Most Dangerous Diseases Spread by Mosquitoes – Mosquis Facts
Most Dangerous Diseases Spread by Mosquitoes – As the last tint of sunlight fade into the dark, the blood-sucking vampires straighten their imaginary collars and set out in search of their prey. And then, they find you. The mere smell of your savoury blood makes them go weak on their knees. They come close and start gauging you from head to toe. Even the most personal spaces are not so personal for them. With their compound eyes, they scan every bit of your body, part by part, inch by inch.
Once satisfied, they come closer to your ears and hum a sleepy music from the evil book of Lethal Hypnosis and then they gradually inject their six-needled proboscis deep inside your skin, savouring every drop of your blood. These nocturnal vampires are called mosquitoes.
These teeny-tiny monsters can give you an extremely hard time if you are not aware of their presence for these otherwise harmless wingy-thing are known to be the carriers of some of the most deadly diseases and epidemics in the world.
Have a look at the menace that these tiny death-bearers can bring!
Most Dangerous Diseases Spread by Mosquitoes
1) Dengue Fever (Diseases Spread by Mosquitoes)
Also known as Breakbone Fever and Dandy Fever, Dengue is one of the most widespread mosquito-borne disease. Mostly caused by the monsters of Aedes genus (Geek alert!), female Aedes Aegypti is the main culprit of this fearsome disease. Another vector for this disease is Aedes Albopictus, the Asian tiger mosquito (though the number 1 mastermind remains Madam Aegypti!). Aedes is a Greek word meaning unpleasant or odious (Well, the havoc that these Aedes women wreak, can you blame the Greeks!)
And not every dark monster hunts at night. This one, for instance, feeds in broad day light. Its favourite hunting time is early in the morning and during twilight (Another reason for staying indoors and avoiding those long morning and evening walks! Feast for the Lazy Bums!)
Widely found in Southeast Asia, sub-Saharan Africa, south and Central America, Madam Aedes Aegypti carries the dengue virus from an already infected person to a healthy person. Symptoms include severe pains in the joints and muscles, headache and high temperature. If this persists, it develops into deadly complication called Severe Dengue.
According to WHO, over 50-100 million cases of dengue are registered worldwide per year and the number of people living in dengue endemic countries is a whooping 3 billion! This puts almost half of the global population under risk. With an early diagnosis and proper treatment mortality rate goes down below 1% (Phew! Such a relief!) but the entire process of treatment to recuperation to complete recovery remains extremely discomforting.
We do have a vaccine for this but there are several restrictions on that. More on this some other time!
2) Zika Virus Disease
More deadly in children than in adults, Zika virus is another disease carried by the Aedes Aegypti and Aedes Albopictus mosquitoes. A curse for the under-developed Africa, it is also widespread in south and central America and Southeast Asia.
Babies affected by Zika monster develop a condition called Microcephaly wherein the size of the skull is extremely reduced. During the first trimester of pregnancy, this disease is transmitted from the expected mother to the baby.
While not many adults are infected by Zika, the ones that do get, rarely develop symptoms like joint pain, conjunctivitis, fever, rash etc. These usually subside after a few days and often have no chronic consequences.
Heard of Abyzou in the folklores? Well, Zika can well be one of her minions!
3) Yellow Fever (Diseases Spread by Mosquitoes)
The Uncrowned Empress of Mosqui Kingdom, Aedes Aegypti, is behind this. With its sidekicks, fever and jaundice, this disease can make you look like a dried up lemon!
Endemic to African tropical areas, Central and South America, this can very well take a form of an epidemic!
Although, WHO estimates that 50 % of victims stand a high risk of death, we do have an extremely effective vaccine now that builds up the immunity for this disease in mere 10 days! There are some countries like Uganda and Sierra Leone, that list Yellow Fever Vaccination as one of the key requirements if you want to enter their borders. Once taken, you are immuned for life! (Great deal, huh!)
4) West Nile Fever (Diseases Spread by Mosquitoes)
Caused by West Nile Virus and carried by the infamous Aedes Albopictus or Asian Tiger mosquito, West Nile Fever has few or no symptoms. However, around 20% patients do develop rash, nausea and fever. In extreme rare cases, a patient may develop encephalitis or meningitis along with neck stiffness and seizures. If the nervous system is affected, the chances of death stand at 10%.
This can be dangerous for the elderly. A low immune system is a hot-bed of all diseases, and this one is not an exception. It is native to Africa and Asia but cases have been found is US, Italy, Greece and France as well.
Usually it takes weeks to months to recuperate completely. There is no vaccine or drugs till date. (Bad News!)
5) Malaria (Diseases Spread by Mosquitoes)
Among 400 different species of Anopheles mosquitoes, there are around 30 madams Anopheles who are known to be the vectors of Malaria. These nocturnal creatures prefer hunting between dusk to dawn.
Although it can be prevented and is a curable disease, the estimated count of deaths by Malaria was 405000 out of 228 million cases in 2018 (Who said that? Well, WHO said that.)
Children under the age group of 5 are most susceptible to this disease which WHO called “life-threatening”. The early symptoms, including fever, chills and headache, usually takes 10-15 days to appear in a non-immune infected person. Other symptoms in children include anaemia, respiratory and metabolic discomfort etc. In adults, multiple organ failure can well be a symptom. (The kidneys and/or the liver can fail and the spleen can just rupture!) If left untreated within 24 hours, it can develop into severe complication that might lead to death.
Malaria can go up to your brain and can cause brain inflammation and damage which is accompanied by seizures and coma. (Nightmarish!)
And it can reoccur even after being fully cured! Same goes for Dengue btw. We do have medicines for Malaria but no 100% sure-shot vaccine.
The world seems like a dark place to live in after reading this, isn’t it? A teeny tiny mosquito doesn’t only suck out blood out. It has the potential to suck everything we have ever earned in life…it can suck the life itself out of us! And we, the most brilliant of all creatures on earth with such a powerful mind are still unable to come up with a sure-shot panacea for these diseases.
The cases per year are surely decreasing. Google categorizes these disease to be “extremely rare”. But under-developed countries like Africa and the developing countries of Asian Continent still stand at a high risk zone. Team Top99list prays for a speedy discovery and easy accessibility of the Cure.
To lighten up the mood post this grave topic, lets our eyes widen while reading some of these amazing facts about Mosquis!
- There are about 3000 different species of mosquitoes in the world.
- They are as old as the dinosaurs! (400 million years! Definitely more resilient than Dinos!)
- These babies can remember your smell. (Huge fans, huh! ;))
- Mosquis need water to breed. But they do have their own weird preferences. Aedes Aegypti prefers clean standing water for breeding. (Yeah, empress got OCD.) Anopheles likes it dirty! She lays eggs in polluted water.
- They live for around 10 to 56 days. (And creates all the menace in these few days. Such creativity!)
- Mosquis don’t have teeth. They have a sharp needle like thing called proboscis to suck and feed on us. Unfortunately, proboscis is not ‘a’ needle-like thing to be precise. It is a complex system of 6 sophisticated needles called stylets that pierces through the skin.
- Mosquis are considered to be the deadliest animals in terms of human death. (More than snakes and sharks!)
- Only Madam Mosquis bite. But not because they are bad. They are just moms! A female needs human blood protein for laying and developing her eggs. (Mommy becomes a hunter for their kids, people! She isn’t a bad person.)
- What do they eat? Males are saintly people surviving just on nectars and other plant-based food. (Vegan Saint!). Females, too, feed on that. Just that they need blood for their babies.
- They have six long slender legs (Beauty!) and a small simple brain that is enough for sight, movement, taste, smell and sensing heat. (Okay. Beauty without a ‘Brainy’ Brain).
