The deadly disease like Dengue gives bad impact on health of public and cause by the bite of Aedes mosquitoes, breeds in stagnant and clean accumulated water. Dengue leads to fever first which is painful, debilitating mosquito borne disease caused by any one of four viruses. These viruses caused West Nile infection and yellow fever which is so harmful for the public health and commonly causes death of infected person. Dengue fever is caused by the bite of an Aedes mosquito infected with a dengue virus (Abdelrazec and et. al., 2016).The mosquito gets infected when it bites a person with dengue virus in their blood. It can't be spread directly from one person to another person. After the infection the symptoms dissolved in blood of human and cause severe headache, fatigue, Nausea vomiting, severe joint and muscle pain. Sometimes, symptoms are some and by mistake treated as the flu or another viral infection, which may results badly. So that is why it is essential to get check up or must conduct the blood test at near by clinic or hospital as it is essential to take diagnosis within seven days after the occurrence of symptoms like because there is no vaccines available for the treatment of dengue. According to the recent report of WHO, as of 06 November 2018, the number of cases have been reported since the beginning of this year in Australia are 630 cases of dengue. Moreover, the report of WHO shows the fewer case have been reported to date in 2018 of last five years. There is the graphical representation of the data regarding the cases of dengue reported in Australia since last five years (2013-18). besides this, another report of WHO declares that around four hundred (400) million people gets infected by the dengue each year, with around 96 million resulting illness.

In above table, there are several countries which are affected by the disease of dengues mostly along with the numbers of the cases reported in these countries , involves Cambodia has the highest number of cases reported of that are 8046 cases, in China 1497 cases, in Malaysia 1597 cases, in Singapore 2321 cases and in Australia the number of reported cases are very low in comparison of other countries and that are only 630 cases were reported in Australia since 2013-18.

Most of the people infected have few or no symptoms, about one or four people infected by dengue virus. According to disclosed data of World Health Organisation that around hundred million people get sick. There are some regions in which high risks of dengue is prevailing namely, South east Asia, the western pacific, the eastern Mediterranean, the Americas, the Caribbean and in many regions of South Africa (Gubler and Paredes-Esquivel and et. al., 2016). As there are no special vaccines are available for the treatment of dengue so it is essential to take treatment within few days of occurrence of symptoms. Some problem occurs due to the occurrence of symptoms of dengue, within starting few days. Some problems are .

  • Fever after the infection.
  • Eye pain(mainly behind eyes)
  • Nausea and vomiting
  • rash
  • muscle joint or bone pain.
  • Unusual bleeding(from nose or gums bleed, small red spots under the skin, or unusual bruising).
  • Drowsiness or irritability in starting days, faced by the infected individual.
  • Difficulty in breathing, the dengue also affects the respiratory system.
  • High sensitivity of stomach.

Moreover, It is a prevalent disease which run throughout tropics and subtropics. This kind of fever is caused by virus, where there is no specific treatment. The prevention of dengue fever is caused by mosquitoes which carrying virus. Their effects came on persons like red splotches on skin, black coloured stool and weakened immunity. In this, it is not directly effects from one person to another. Their is a need of Aedes mosquito for transferring of viruses. Rapid increasing of temperature creates rashes in all over body including face. The virus opt in a body during daylight hours or particularly in morning or at late noon (World Health Organization, 2017). This kind of diseases are more prone in some tropical and sub- tropical areas. Period of incubation, symptoms shown after bite of mosquito can be implement in between three to fifteen days. Most of the physicians first try to complete blood test with the use of metabolic panel (Saadatian-Elahi, and et. al., 2016).

Some measures in order to protect the public from the hazardous diseases like dengue.

  • By applying mosquito repellent, ideally one containing DEET(Schneider, 2016).
  • Prevent mosquito breeding inside and outside of home.
  • Avoid visiting the areas prone to mosquitoes.
  • Do not use an inspect repellent for infants under two months of age(Wilder-Smith and Gubler, 2015).
  • Wear long sleeves and long pants to cover your arms and legs.
  • Use mosquito net while sleeping.

In order to prevent dengue or for the treatment of dengue some suggestions provided by the World Health Organisation such as, by taking acetaminophen or paracetamol to reduce the fever and relief from joint pain. But don't take ibuprofen and aspirin, Dengue virus symptoms are founded in blood within the starting days after infection, if mosquito bites an individual it can spread the virus to other individual also by bites. Hence, it is essential to prevent others from getting sick, then protects the individual or individuals from mosquito bites within the first week of illness


From the above study it has been concluded that the hazardous disease like dengue gives bad impact on public health and the main problem is that the deadly diseases can results in heavy loss of human life, as due to particular vaccines are available fo0r the treatment of dengue hence, it is essential for every one to use the preventive measures in order to make safe the loved ones and society from the these types of harmful diseases. Regarding prevention from these diseases several organisations like World Health Organisation Centre and other institutions working for public health issued several suggestions in order to prevent these diseases.
