Dengue prevention efforts are limited to the control strategies of its vector and the management of breeding sites. New alternatives for dengue vector control that are sustainable and more environmentally friendly are needed to complement the government's current efforts. Research on Wolbachia-infected Aedes aegypti Linnaeus mosquitoes as an alternative biocontrol strategy has been performed in Yogyakarta City. However, one of the concerns of the community members and stakeholders about this technology is the safety aspect regarding the transmission of Wolbachia to other species and the possibility that humans will contract Wolbachia. This study aimed to address these concerns, namely to find out whether horizontal transmission of Wolbachia occurred from A. aegypti that were released to other species and whether residents living in the released areas were infected with Wolbachia. The research was conducted in Dusun Nogotirto and Dusun Kronggahan (Sleman Regency), as well as in Dusun Jomblangan and Dusun Singosaren (Bantul Regency), Yogyakarta Special Province. Wolbachia qPCR screening using the target gene WD0513 was performed on 922 Culex quinquefasciatus Say and 331 Aedes albopictus (Skuse). ELISA test was carried out on 190 pairs of plasma samples, namely the sample before the Wolbachia frequency was established (still <80%) and the sample after it was established (>80%). The results showed no evidence of Wolbachia transfer from Wolbachia-infected A. aegypti to other mosquito species coexisting in the same habitat or to humans. This study corroborates the safety evidence of Wolbachia-infected A. aegypti technology as an alternative to control dengue virus transmission

An efficacy study on wMel Wolbachia-infected Aedes aegypti technology conducted by the World Mosquito Program (WMP) Yogyakarta showed the reducing of dengue incidence in Yogyakarta City. Following this successful result, the intervention was scaled up into two neighbouring districts: Sleman and Bantul. This paper describes our experience in mass production for providing release material for a larger area to reach the deployment target, which includes insectary requirements, mass production protocols, and diagnostic screening. This review may serve as a reference guidance for national mass production for wMel Wolbachia-infected Ae. aegypti.

Purpose: Retinoblastoma is the most common primary intraocular tumour in children. Its prognosis varies depending on the stage of diagnosis. However, in developing countries such as Indonesia, retinoblastoma still has a poor prognosis as most patients present at advanced stages. This research aims to explore the factors influencing the delay in patients with retinoblastoma reaching referral health facilities from the perspective of their families. Methods: A qualitative study using a phenomenological approach was conducted to gather family perspectives through in-depth interviews via WhatsApp calls. Each interview lasted 20-25 minutes and included families of retinoblastoma patients who had visited the eye clinic at Sardjito General Hospital at a late hour. “Late” was defined as tumour spread beyond the eyeball (intraorbital, spread to the optic nerve, or intracranial spread) or involvement of more than one eye. Audio was transcribed verbatim using a mobile phone voice recorder, and open coding was performed using Open Code 4.02 software to identify meaning units, codes, and categories. Triangulation and peer debriefing were used to ensure validity and trustworthiness. Results: Several categories emerged, including reasons for seeking help, trust in medical professionals, family compassion, and challenges in health facilities. Challenges in health facilities, particularly diagnostic capabilities, communication, and education about eye tumours, along with negative emotions like denial from families, contributed to delays in seeking treatment for retinoblastoma patients. Conclusion: Family compassion plays a positive role in encouraging families to seek medical help. However, challenges in health facilities, particularly in diagnosis, communication, and education about eye tumors, as well as family denial, contribute to the delays in retinoblastoma patients reaching referral health facilities.
