ABSTRACT
Introduction. Dengue Hemorrhagic Fever (DHF) is still a public health problem even in the era of the COVID-19 pandemic in 2020, including in Indonesia. This study aimed to analyze the incidence of DHF based on the integration of climatic factors, including rainfall, humidity, air temperature, and duration of sunlight and their distribution. Materials and Methods. This was an ecological time series study with secondary data from the Surabaya City Health Office covering the incidence of DHF and larva-free rate and climate data on rainfall, humidity, air temperature, and duration of sunlight obtained from the Meteorology and Geophysics Agency (BMKG). Silver station in Surabaya, the distribution of dengue incidence during 2018-2020. Results and Discussion. The results showed that humidity was correlated with the larvae-free rate. Meanwhile, the larva-free rate did not correlate with the number of DHF cases. DHF control is estimated due to the correlation of climatic factors and the incidence of DHF, control of vectors and disease agents, control of transmission media, and exposure to the community. Conclusions. The integration of DHF control can be used for early precautions in the era of the COVID-19 pandemic by control-ling DHF early in the period from January to June in Surabaya. It is concluded that humidity can affect the dengue outbreak and it can be used as an early warning system and travel warning regarding the relative risk of DHF outbreak.Copyright © the Author(s), 2023.
ABSTRACT
The first positive case of coronavirus disease 2019 (COVID-19) in Indonesia was announced in March 2020. Since then, the positive cases have continued to increase. This condition prompted the government to adopt the Large-Scale Social Restriction (LSSR)/Pembatasan Sosial Berskala Besar (PSBB). Some areas included in endemic regions for dengue face two problems: overcoming COVID-19 and Dengue Hemorrhagic Fever (DHF) simultaneously. Five economic growth center cities/districts in East Java Province (Gresik, Bangkalan, Surabaya, Sidoarjo, and Lamongan) were affected by the COVID-19 pandemic and dengue fever. This was a quantitative research with a comparative design study using the Wilcoxon test to compare the cases of DHF pre-COVID-19 and during the COVID-19 pandemic. The Wilcoxon test result showed no significant difference with a p-value of 0.319 (p-value>0.05). It can be concluded that DHF still becomes a problem in five cities/districts in East Java Province even though LSRR was applied. Extra attention is needed to overcome DHF. One of the efforts to prevent and control DHF during the COVID-19 pandemic is to build community independence through the one house one health cadres' movement.
