“Only certain countries in the world have the mosquito required to carry this virus. Some types of Aedes mosquito can spread the Zika virus, particularly Aedes Aegypti but also possibly Aedes Albopictus. Australia is home to the Aedes Aegypti mosquito that can carry the virus, this mosquito is currently found in parts of Northern, Central and Southwest Queensland. Aedes Albopictus is found in the Torres Strait Islands” (Department of Health, 2018). This means that the Zika virus can be transmitted to Australia however, the only cases found in Australia are from people who received the virus overseas and brought it back with
Review Introduction Dengue fever, which is also known as breakbone fever, is one of the most rapidly spreading mosquito-borne viral disease in the world which is caused by four dengue virus (DENV-1-4) . The disease is transmitted through the biting of Aedes aegypti, the primary vector of dengue fever . The symptoms of this disease range from mild fever to severe problems like the failure of circulatory system and eventually can lead to death. History of dengue Chinese medical encyclopedia from the Jin Dynasty (265–420 AD) had recorded the first case of dengue fever which was associated with “water poison” by flying insects . Dengue has emerged as an extremely serious public health problem in the Western Pacific Region as more than 100 million dengue cases were reported in Malaysia, Vietnam, Philippines and Cambodia which these four countries have the highest number of dengue cases and deaths between
Introduction Bluetongue is an infectious, non-contagious viral disease of ruminants and camelids transmit¬ted by Culicoides biting midges. It is caused by the bluetongue virus (BTV) and is placed in the epizooties list of diseases international. The manifestations of bluetongue range from an in apparent to a fatal outcome depending on the serotype and strain of the virus and the species, breed and age of the infected animal; older ani¬mals are generally more susceptible. Clinical signs are usually detected in fine-wool breeds of sheep and the white-tailed deer and include fever, facial oedema, haemorrhages into, and ulceration on, the oral mucosa and coronitis. Bluetongue typi¬cally occurs when susceptible animal species are introduced into areas with circulating virulent BTV strains, or when virulent BTV strains extend their range to previously
Malaria Overview- Malaria is an existence debilitating blood disease created by parasites transmitted to people through the nibble of the Anopheles mosquito. Once an infected mosquito nibbles a human and transmits the parasites, those parasites duplicate in the host's liver before contaminating and obliterating red platelets. The disorder can be controlled and treated if analysed right off the bat. Lamentably, this is impractical in a few zones of the world ailing in therapeutic offices, where jungle fever flare-ups can happen. Causes- Malaria fever is brought on by the nibbles from the female Anopheles mosquito, which then contaminates the body with the parasite Plasmodium.
It forces the new gene to become dominant in the following generations overpowering the old gene almost completely. Thanks to this twist, 99.5% of all the engineered mosquitos’ offspring will carry the anti-malaria edit. If we were to release enough engineered mosquitoes into the wild to mate with normal mosquitoes, the malaria blocking gene would spread extremely
The Zika virus was first observed in monkeys and is spread by mosquitoes in humid climate areas such as Uganda and Tanzania. Zika virus is very similar to the virus that causes dengue. To prevent yourself from this virus is to avoid visiting tropical areas. Should you have to visit a tropical country then, I strongly advise you to wear long sleeves and long trousers to avoid being bitten by insects, which is the main infection route. If you have been bitten by an insect while travelling seek medical attention.
Both are transmitted by the Aedes aegypte mosquito. They are both affecting millions of people worldwide and the Wolbachia has been discovered as one of the ways to fight against them. Scientists have been infecting the mosquitoes’ transmitters of the virus with the bacteria and it turns out that after the infection their lifespan is shortened, and since they need to be adults to transmit the sickness they don’t live enough to able to do that and the virus can’t be reproduced as well because they can’t carry it. But insects are not the only arthropods that are infected by Wolbachia. Nematodes is another example that has been studied by scientists that are also looking for answers and to know more about this relationship.
Malaria can be transmitted through the female Anopheles mosquito, however, any other mosquito or insect cannot transmit it. Once the mosquito bites an infected person, the person’s blood is extracted which consists of microscopic Malaria parasites. Around a week later, when the mosquito is ready for its next meal, it bites another person (who is not infected) and the Malaria parasites fuse with the mosquito’s saliva and are injected into the person that is being bitten. The female Anopheles mosquito is not the only thing that can transmit Malaria. The Malaria parasite is present in the red blood cells of the infected person, therefore Malaria can be transmitted via organ transplants (or donations), blood transfusions (or donations of contaminated blood) or using the same needles/syringes with contaminated blood.
The West Nile Virus is a disease caused by mosquitoes during mosquito season. This virus can infect humans, birds, mosquitoes, horses and some other types of mammals. In the summer of 2002, there was a huge West Nile Virus epidemic in Africa and kept spreading around the world. When having this deadly virus you can 't really tell when you have it because there 's no symptoms. Also you can have the virus and have very mild symptoms.
