Surveillance of Dengue Fever and Domestic Aedes Aegypti Breeding Sites in Jeddah, Saudi Arabia.

Dengue fever remains a public health problem. Environmental factors influence the mosquito Aedes aegypti’s growth, especially if there are many containers in the neighborhood. The community of Nanggungan Village have a habit of storing water in containers, therefore, they risk to become breeding sites for mosquitoes. This study aims to identify the Maya Index status of Aedes aegypti between Tegalrejo and Krajan Kidul Village. The research was observational with a cross-sectional design. Total samples were 200 homes, which 100 homes from Tegalrejo and 100 homes from Krajan Kidul Village, taken by simple random sampling. The measurement of variables employed observation sheet and analyzed in a descriptive approach. The number of containers observed in the Tegalrejo Village was 394 units, and Karajan Kidul Village was 391 units. Maya Index statuses in Tegalrejo (92%) and Krajan Kidul Village (88%) were low. Maya Index status in Krajan Kidul (13%) was higher than Tegalrejo Village (8%). House Index (HI) in the Tegalrejo (18.0%) was lower than Krajan Kidul Village (25.0%), Container Index in Tegalrejo (5.30%) was lower than in Krajan Kidul Village (8.95%), Breteau Index in Tegalrejo (21.0%) was lower than in Krajan Kidul Village (35.0%), Density Figure in Tegalrejo and Krajan Kidul Village indicated a scale of 3 and 4. Based on the MI’s status, Tegalrejo and Krajan Kidul Village were included as a low-risk category of mosquito breeding sites. Based on the density number of larvae, two villages have a moderate risk of Dengue Fever transmission. The community should implement the Mosquitoes Breeding Sites Eradication Program (PSN 3M Plus) and minimize the presence of the containers.

Objectives: The elimination of key breeding sites of dengue vector is applied worldwide to control the vector density under the critical epidemic threshold. This study aimed to identify key breeding sites of Aedes mosquitos and associated factors in Huaylau village, Pakse city, Champasack province in Laos in 2019. Methods: This was a cross-sectional study, combining of immature stage survey of Aedes mosquitoes in all water and discarded containers and the community’s knowledge and practices on the prevention of dengue fever in all 240 households in Huaylau village. Multivariate logistic regression was applied to identify factors associated with the absence of Aedes larvae and pupae in the village. Statistical significance was set at a p-value less than 0.05. Results: Among the 720 water and discarded containers surveyed, the study found 654 Aedes larvae and pupae; of which 94.6% were immature Aedes aegypti. Key breeding sites of Aedes aegypti included water jars (34.2%), plastic drums (30.7%), tanks < 500 litter (14.7%), and discarded containers (12.6%), while that of all Aedes albopictus was discarded containers. The community’s better practices on the prevention of dengue fever contributed to the increased odds of the absence of Aedes larvae ad pupae by 1.612 (95%CI: 1.218-2.134, p<0.01), and the cleanliness of the house were associated with the increased odds of 4.072 of the absent Aedes larvae and pupae in the participated households (95%CI: 1.589-10.434, p<0.01). Conclusions: Aedes aegypti mosquitoes in the Huaylau village laid their eggs in various breeding sites, including water containers and discarded containers while discarded containers were the only key breeding site of Aedes albopictus. Better practices on dengue prevention and better hygiene conditions of the houses contributed to the absence of Aedes larvae and pupae. Special attention should be paid to the clearance of all discarded containers and education of the community people to cover water containers in the village.

Near Future

Since 1994, dengue fever (DF) transmission rates have increased significantly in Saudi Arabia (KSA). Climatic, geographic, and demographic conditions make KSA especially suitable for DF’s spread. Still, there are insufficient strategies for controlling the Aedes species that transmit DF virus (DENV). To develop effective management strategies, it is necessary to identify Aedes species and the ecological habitat of larvae in Makkah Al-Mokarramah, KSA. We conducted a longitudinal survey of Aedes mosquitoes in 14 localities from January 2015 to December 2015. World Health Organization (WHO) inspection kits for larvae were used to detect and sample larvae, along with pictorial keys. A total of 42,981 potential Aedes larval breeding sites were surveyed. A total of 5403 (12.6%) sites had at least one water source positive for Aedes aegypti (Linnaeus) mosquitoes. Among the total of 15,133 water sources surveyed within the sampled sites, 1815 (12.0%) were positive for Aedes aegypti. Aedes aegypti was the only Aedes species identified in the course of the survey. The presence of such a large immature population may indicate an imminent outbreak of DF in the near future unless proper implementation of control and elimination of Aedes aegypti are undertaken. Additionally, the adaptation of Aedes aegypti to the arid climate of Makkah needs further investigation.

Mosquitoes can act as vectors for many disease-causing viruses and parasites through carrying these organisms from person to person. The objective of this study was to evaluate the susceptibility of Aedes aegypti larvae to some insecticides in Jeddah Governorate. Mosquito larvae were collected from all the available breeding sites in Jeddah municipalities using standard larval collection kits. The diagnostic doses (LC50 and LC90) were calculated from the mortality and concentration data. The larvicides Pirimiphos methyl, Fenitrothion, Bifenthrin and Cypermethrin were tested against the larvae of Ae. aegypti mosquito. The results showed positive correlation between the concentrations under investigation and mortality% of the treated larvae. Cypermethrin gave strong effect against Ae. aegypti larvae (LD50 0.0015 ml/L) followed by Pirimiphos methyl (LD50 0.0020 ml/L), Bifenthrin (LD50 0.039 ml/L), and at last rank Fenitrothion (0.041 ml/L). The same trend was obtained in LD90s. Ae. aegypti in Jeddah was susceptible to Bifenthrin, Cypermethrin, Pirimiphos methyl and Fenitrothion. Further studies should be run to conduct an intensive and appropriate vector control program in Jeddah Governorate.
