Mosquitoes are not like dirty syringes, spreading viruses in droplets of blood from person to person. When a mosquito bites, she injects saliva to assist blood-sucking.
Unfortunately, mixed in with that spit can be a virus.
For the saliva to become infected, the mosquito must first bite a person or animal infected with a virus. As the mosquito becomes infected, the virus spreads throughout the body of the mosquito; from the legs to the head.
Inside the head are the mosquito’s salivary glands. When they become infected, they can pass on the virus to the next unsuspecting host.
From acquiring to passing on the virus, the process can take anywhere from a few days to a couple of weeks.
Working out which mosquitoes spread which viruses are critical to developing strategic responses to outbreaks of disease.
They’re some of the common diseases spread all over the world by mosquito bites:
Malaria is the most well known mosquito-transmitted disease. It’s caused by a small parasite that lives inside the mosquito and is spread from one person to another when the mosquito attacks. It’s spread mainly by a specific kind of mosquito (the Anopheles mosquito) which can be found in particular regions of the world. The most common signs and symptoms of malaria are fever, headaches, nausea or vomiting, and muscle and joint pain. People residing in or even visiting, locations, where the Anopheles mosquito is available, can reduce the danger of malaria by taking drugs regularly and using steps to prevent being bitten.
Occurring extensively in Australia, the Ross River disease is spread from pets or animals to people by several types of mosquitoes. Although some people attacked with this virus don’t have any, or just minor, signs and symptoms, others may have a fever, joint pain and swelling, and an allergy. There’s no particular treatment method but medications may become to help reduce the signs.
The actual Barmah Forest virus is also common in Australia and leads to a similar sickness to Ross River virus disease but the signs and symptoms generally last for a smaller period. The virus is distributed from pets or animals to people by mosquitoes. Once again, there’s no particular treatment method for this disease, but medications may become to aid manage the signs and symptoms.
Murray Valley encephalitis is a quite uncommon disease involving swelling of the human brain tissue. The illness is due to infection with a virus that’s distributed by the bite of afflicted mosquitoes. The mosquito responsible is located throughout Australia and breeds in surface area pools of water. Drinking water birds, like herons, are a normal reservoir of the computer virus. Many people afflicted with the Murray Valley encephalitis virus don’t create signs and symptoms, but other people may have a high fever, severe headaches, neck tightness, irritability, seizures (or fits), and sleepiness. Fast healthcare suggestions should be needed if you have these signs and symptoms.
The mosquito liable for transmitting the dengue virus can be found in most warm regions of the world, like North Queensland, Sydney. The mosquitoes breed in pots that hold water and bite in the daytime, not mostly at night or afternoon like other kinds of mosquitoes. People afflicted with the virus may have zero indicators, but some others may experience high fever, severe headaches, muscles, and joint pain, rash and severe weakness. In rare situations, dengue fever may be serious and even fatal. You should get quick medical assistance if you believe you’ve dengue fever.
