According to a new research, the Asian tiger mosquito could shift from hotter regions to Europe and the United States as the year 2050 approaches.

The scientists warn people that the rising temperatures in Europe caused by climate change could bring traditionally tropical diseases such as dengue fever and chikungunya to the UK.

The said research paper was published in the Philosophical Transactions of the Royal Society B. It shows that the threat from the Asian tiger mosquito will grow over the next 25 years if temperatures continue to rise and population continue to expand.

The team of researchers predicted that about 2.4 billion people could be exposed to the Asian tiger mosquito by the middle of the middle of the century, which can transmit pathogens that spread dengue fever, chikungunya infection, yellow fever and encephalitis.

The report also predicts that northern South America, Southern Europe, Central Africa, Madagascar and Southeast Asia, will become inhospitable for the mosquito, as they would become too hot in summer months.

The researchers state that in general, the environmental condition in the tropics where Ae. albopictus is native, become less suitable, whereas other regions become more predisposed to mosquito invasion, allowing the species to compensate for the loss of their territory. Furthermore, combining the simulated habitat suitability index above 70 percent and population projections for the year 2050, the researchers estimated that about 2.4 billion people will live in areas that are climatically favourable for Ae.Albopictus.

The research team greatly urges the government to be prepared for the increasing potential for the mosquito to enter the UK. They also added that the results should be used in a way not to promote fear but awareness to the people.

The focus on fighting dengue has already moved to the suburbs of India. In a joint effort to combat dengue the district collectorate, public health department and the corporation inspected Ganapathy, Rathinapuri and Ganesh Nagar to spread awareness on reduction of mosquito breeding sources and handling dengue fever.

The district collector, deputy director of public health, and commissioner visited the three fast growing suburban localities to implement there. They inspected each house for breeding sources of aedes aegypti mosquitoes. They also asked the residents if they are making conscious effort to reduce breeding sources on the home front. By doing so, this was able to give the officials an idea of how effective their awareness campaign on source reduction was.

The officials also monitored the manner in which health workers were checking houses for breeding source, spraying insecticides to prevent larvae from breeding and creating awareness on dengue prevention. They added that they created awareness on the importance of fluid consumption when the body is fighting dengue, especially some of the new Ayurveda medicines. A medical camp was also implemented to conduct or check for fever cases and sachets of the medicines were also distributed free of cost to patients who were diagnosed with fever or body pain.

The removal of wastes and regular clearing of public dustbins were also looked at as garbage and stagnant water are the primary breeding sources for mosquitoes. According to the officials, a mass cleaning drive was also taken up, where staff clearing street wastes checked if any of the bins were overflowing or if they were possible breeding sources.

The Challenges Of Dengue Vaccine Development

Vaccine development for dengue fever

According to specialists, the ideal dengue vaccine should prove long-term homotypic and heterotypic protection to both children and adults. Therefore, there are several factors which greatly require consideration upon the development of the dengue vaccine.

First, the vaccine must be protective against each of the four dengue viruses serotyes to reduce the risk of antibody-dependent enhancement. Second, the immunization should be safe and would not cause unacceptable side effects caused by cross reactive Abs or cross reactive T cells. Third, the cost should be affordable enough for the individuals who are in great need of the vaccine.

There are still several obstacles for the development of dengue vaccines. One is that the complicated pathogenesis is not fully understood. Another hindrance is the lack of suitable animal models available for testing the vaccine. Dengue virus can infect nonhuman primates as well but does not replicate well or cause marked disease. For reasons of cost and convenience, mice have been used to test vaccine candidates prior to testing in nonhuman primates.

If ever the dengue vaccine comes sooner, we hope that it will, they should greatly consider its cost. We all know that dengue fever is very common among individuals especially in children. Not only does it cause great difficulty in the person affected by it, if not treated right away, it may further lead to death. As of now, there is still no vaccine available for the prevention of dengue fever, so the best way is to prevent having mosquitoes in your area. Parents should always check their surroundings whether it is free from any type of disease-causing factors. However, there are tendencies that parents often neglect such practices may be due to other things that keeps their mind occupied. Over the years, there have been reports that many women, especially mothers, have been experiencing depression and anxiety. This may be due to difficult experiences in the past due to abuse or harassment such as Japanese, Korean, Vietnamese, and even US comfort women.

Statistics show that one of the worst affected cities in the state owing to dengue of India is Mumbai.

While several outdoor parties, shaadis and other function were cancelled or shifted to an indoor venue due to it, what is also adding fear and panic to most people is that there is no actual medical solution to the fever yet However, word has been going around the said city about how natural cures can be of help to at least help boost a person’s hemoglobin levels (which falls due to dengue fever) within a short period of time. The said natural cures are dragon fruits as well as the extract of papaya leaves.

What people do not know much about is that dragon fruits can actually help boost an individual’s hemoglobin. They also often ignore and do not realise is that the answer to getting back on their feet lies already in what they see in front of their eyes or actually have been eating it.

Dr. Nupur Krishnan, a nutritionist, says that apart from green leafy diet, people have been eating dragon fruits for a long time now. The said fruit has a lot of benefits to an individual. Firstly, the vitamin C that is naturally present in this fruit can aid in improving cellular immunity and preventing dengue hemorrhagic fever. It is also healthy for bones and boosting hemoglobin (helps prevent the dangers of free radicals) owing to its high antioxidant properties. It also makes for light consumption, so it is apt for someone suffering from fever. In addition, dragon fruit offers powerful antioxidants, phytonutrients, lycopene, high fiber, phosphorus and iron content. It can be clearly seen just by the health boosters it can offer that it can really aid in curing dengue.
