The females of most species of mosquito only need to bite twice in their lifetime in order to lay over three hundred strong eggs. (actforlibraries.org)
There are about 3,500 species of mosquito around the world, but not all can cause serious illnesses. (accenttheparty.com)
Bites11
Unfortunately, this is also the minimum number of bites needed for female mosquitoes to transmit disease from one person to another. (actforlibraries.org)
As tempting as it might be, avoid scratching mosquito bites. (wonderopolis.org)
Can one be 'allergic' to mosquito bites? (ecarf.org)
For most people, mosquito bites are a harmless nuisance. (ecarf.org)
That's because whenever a mosquito bites, it releases some saliva , which contains proteins that prevent clotting, dilate the blood vessels, and make it easier for the mosquito suck in the blood. (ecarf.org)
Repellent2
We all know that citronella is a powerful mosquito repellent and featured in most mass produced bug sprays. (dvorakexpeditions.com)
In addition, public health authorities advise the public to use mosquito repellent which, when applied to skin and clothing, will turn the pests away before they were able to bite. (accenttheparty.com)
Bite is due2
The familiar itching of a mosquito bite is due to the reaction of the body's immune system against one or more parts of this compound. (actforlibraries.org)
In most cases, severe swelling after a mosquito bite is due to inflammation rather than an allergy. (ecarf.org)
Saliva6
Mosquito saliva contains a substance - called an anti-coagulant - that keeps your blood flowing so she can quickly get her fill of your blood. (wonderopolis.org)
It detects the presence of the mosquito saliva and tells your body to produce a substance called histamine to fight it. (wonderopolis.org)
For this to be a true allergy , the immune system would need to develop antibodies (immunoglobulin E) against the proteins in the mosquito saliva, which are harmless in themselves. (ecarf.org)
Although there are no conclusive studies on the prevalence of allergies to mosquito saliva, we do know that their significance has been overshadowed by bee and wasp venom allergies. (ecarf.org)
Up until now, only a few allergens in mosquito saliva have been identified and made available for test preparations. (ecarf.org)
Environmental toxins or high levels of protein in the saliva of the mosquito are often blamed. (ecarf.org)
Transmit2
In the United States, some mosquitoes carry and transmit a virus called West Nile Virus . (wonderopolis.org)
In other areas of the world, particularly Africa, mosquitoes can carry germs that transmit potentially-deadly diseases, like malaria . (wonderopolis.org)
Eggs3
However, a female mosquito will lay many more eggs and the resulting young will be much stronger if she has fed on blood during the week of their early development, right after mating with the male. (actforlibraries.org)
Blood is richer by far than nectar in the protein and nutrients the eggs need, to the point where a single bite can balance out more than a week of feeding on nectar alone. (actforlibraries.org)
She needs this blood meal to develop new eggs. (ecarf.org)
Body's2
Once close enough to living prey, the female mosquito can directly detect the infrared radiation of the body's heat. (actforlibraries.org)
While you might not immediately realize when you've been "bitten" by a mosquito , your body's immune system is fully aware of what's going on. (wonderopolis.org)
Diseases9
Common mosquito-transmitted diseases are several different forms of encephalitis, yellow fever, and especially malaria, which is endemic in most tropical and subtropical parts of the world. (actforlibraries.org)
Most such diseases are specific to a single mosquito species and host species, although West Nile virus can infect most warm-blooded creatures. (actforlibraries.org)
Fortunately the vast majority of blood-borne diseases, such as AIDS, cannot be transmitted from one person to another via mosquito bite, because the pathogens which carry them are destroyed in the mosquito's digestive system. (actforlibraries.org)
According to one study, under the worst-case scenario where the average global temperature has increased by 5 degrees Celsius, up to 1 billion people could become exposed to diseases caused by mosquitoes by 2080. (accenttheparty.com)
The study found that over 200 million and 150 million from Western and Eastern Europe respectively will be vulnerable to mosquito-borne diseases for the first time by 2080. (accenttheparty.com)
In contrast, the warming may cause a decline of mosquito-borne diseases in South Asia and sub-Saharan Africa, but only because these regions will be too hot for mosquitoes to survive. (accenttheparty.com)
If the warming is maintained to below 2 degrees Celsius, which is the goal of the Paris Accord, more places will be exposed to mosquito-borne diseases for the first time, but the number is halved. (accenttheparty.com)
Houses in countries where mosquito-borne diseases are endemic also have screens on windows and doors. (accenttheparty.com)
In an effort to completely eradicate the populations of Aedes aegypti , Oxitec, with the financial backing from the Bill and Melinda Gates Foundation, released over a hundred thousand genetically modified mosquitoes in Florida with the hopes that it will stop the spread of dengue, Chikungunya, Zika, and other diseases.

Proboscis3
The male mosquito doesn't even have a proboscis, that part of the mosquito which sticks into your skin to extract the blood. (actforlibraries.org)
With her proboscis underneath your skin, a female mosquito searches for a blood vessel. (wonderopolis.org)
The female mosquito lands, pierces the victim's skin with her proboscis, and sucks out the blood. (ecarf.org)
Vessels2
When the histamine reaches the area of skin where the mosquito "bit" you, it causes blood vessels in the area to swell. (wonderopolis.org)
When the blood vessels swell, they also cause nerves in the area to become irritated. (wonderopolis.org)
Female4
In fact, almost the entire diet of male and female mosquitoes alike consists of nectar, a fact which many plants take advantage of in order to cross-pollinate. (actforlibraries.org)
Thus the female mosquito has evolved a hunting strategy for use during her reproductive period only, thereby optimizing the risk of haemophagic parasitism against the reproductive benefit. (actforlibraries.org)
Every year, up to 400 million people around the world are infected with dengue, a viral infection spread through the bite of a mosquito. (accenttheparty.com)
People2
For unknown reasons, some people produce more octenol than others, and are thus more attractive to mosquitoes. (actforlibraries.org)
Not only were there other people like me who are shunned by mosquitos, but also the one thing we all had in common was not hot sauce, onion or garlic consumption. (realchangenews.org)
