- - - - mosquito to human : transmitted when a female added aegypti mosquito bites a human
        
        the mosquito usually bite a lot at once which explains why there is always a cluster of cases at one region
      - human to mosquito : a mosquito becomes infected with the dengue virus when it bites a human with the dengue virus infection. the mosquito gets infected with dengue forever
    - - the signs and symptoms show 4-10 days after being infected and lasts fro around 2-7 days: fever
    - - anthropogenic
        
        climate chnage
        
        increasing temperature lead to lengthen and intensify number of transmissions
        
        mosquitoes breed well in high and humid tempratures.with increasedttmpratures, this increases the rate of biological development of the mosquito which allows them to be able to breed earlier, leading to increase number of transmissions due to multiplying mosquitoes
        
        according to MSS, Singapore's temperature is said to increase at a rate of two times faster than in the world, with an increase of 0.25 degrees Celsius per decade
        
        benefits the dengue virus directly. when a mosquito is infected by biting a human, it needs around 7 days to be infective and this is called the incubation period.
        
        however, with increased temperature, the virus take a shorter amount time to increase and multiple which shortens the incubation period and it can transmit the disease to more people in a shorter period of time
        
        urbanisation
        
        refers to more people moving to the cities to live - increases the amount of people being affected when a mosquito bites because there are more people clustered in one area - the reason why some areas in singapore are have more cases is because these areas have warmer microclimate, and these buildings are older so they have crevices from wear and tear which increases the number of pools of waters in which the mosquitoes can breed in, female mosquitoes give birth to 100 eggs at a time and they can give birth up to three times in their life and also western regions of Singapore have a lot of green forests which are dominated by another Aedes mosquito type, which does not spread dengue
        
        human mobility
        
        with globalisaiotn, increase number of People can travel around the world
        
        more people who visit these countries with dengue will bring the disease to other countries, spreading it to new regions
        
        mosquitoes usually can be found on aircraft or ships being stowedaway

    - - denge is a mosquito borne disease that is caused by the dengue virus.
        
        there are 4 serotypes of the virus, denv-1,-2,-3,-4
        
        spread by Aedes aegypti mosquito
- - - - 60.7 million of children in the world wo are of primary schooling age are not going to school rn
- - - - singapore has the 3rd highest life expectancy
