Climate Factors and Dengue Fever in Jakarta 2011–2015

Abstract

Dengue fever is a public concern because of its outbreak with a high mortality rate.Aedes aegypti as a vector of dengue fever is very sensitive to its environment, especially to climate variability. The aim of the study was to examine the correlation between climate factors (temperature, rainfall, humidity, and solar radiation) and dengue fever cases in Jakarta 2011-2015, since Jakarta is the capital city of Indonesia.It was a quantitative study with an ecological study design. A correlation test was used to determine the correlation between the independent and dependent variables.The study was carried out in Jakarta using secondary data from the Health DistrictOffice of Jakarta for monthly data on dengue fever cases and the Soekarno-Hatta Meteorological Station for daily converted to monthly climate data from January 2011 to December 2015. The instruments used to measure independent variables were a thermometer for temperature, tipping for rainfall index, hygrometer for humidity, and Campbell-stokes for solar radiation. The results showed a significant correlation between the climate variables studied -these were temperature (p-value<0.05, r=-0,293), rainfall (p-value<0.05, r=0,327), humidity (p-value<0.05, r=0,586), and solar radiation (p-value<0.05, r=-0,408) -and dengue fever cases in Jakarta 2011-2015. It was concluded that four independent variables had an influence of the increase in the number of cases. There were two climate variables that had a positive correlation with dengue fever cases, namely humidity and rainfall, while temperature and solar radiation had negative correlations. The highest correlation value was that of humidity with a strong correlation category. The remaining factors, namely temperature, rainfall, and solar radiation, were in the medium correlation category.

Spatiotemporal high-resolution prediction and mapping: methodology and application to dengue disease

“…Solar radiation has a negative impact (− 0.0001), which is consistent with Ekasari et al ( 2018 ), Jaya and Folmer ( 2021a ) and Martínez-Bello et al ( 2017b ). An increase of 1 kJ m −2 day −1 of solar radiation decreases the relative dengue risk by .…”

“…As shown by Rasjid et al ( 2019 ), strong solar radiation negatively influences the breeding and spread of Aedes-spp mosquitoes. A longer spell of solar radiation implies a shortened spell of dawn and dusk, during which the Aedes-spp mosquito preys on animals and humans, particularly 20 to 30 min after sunset (Ekasari et al 2018 ; Jaya and Folmer 2021a ).…”

Association of climate factors with dengue incidence in Bangladesh, Dhaka City: A count regression approach

“…The study found that minimum temperatures showed a strong correlation with dengue incidence from January to March, but closer to the beginning of the dengue season, from April to June, there was a negative correlation. Ekasari, in their study between 2011 and 2015, found the highest number of dengue incidences in April 2014 and the lowest in October 2012, which associates with the wet and dry seasons of the country [ 24 ]. Finally, the surge in the Aedes population is connected with an increase in temperature, relative humidity, and precipitation during the monsoon season, which is followed by an increase in the prevalence of dengue [ 25 ].…”
