Citizen science in public health: Social Media insights into bedbug infestations, control methods and psychosocial effects in Lusaka, Zambia.
Article in Digital health. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Bedbugs are blood-feeding parasites that infest human dwellings, causing discomfort and distress. Individuals affected by such infestations often feel too ashamed to seek help publicly. Social media including Facebook provides a space where people freely share their experiences as it offers some level of anonymity, making it a platform for real-time, community-driven insights. This reflects the concept of informal citizen science, where individuals voluntarily share lived experiences. Objective: This study investigated bedbug infestations in Lusaka using publicly available social media (Facebook) data. Methods: A qualitative case study design was employed using inductive thematic analysis of 1566 publicly available Facebook comments and replies posted between January 2021 and May 2025. Posts discussing bedbugs in Lusaka were purposefully selected using keyword searches. The selected data for thematic analysis came from 3120 comments and replies. Data were analysed using NVivo 12.3, supported by generative AI while quantitative data was generated in excel. Results: Most participants identified public transport, low-cost lodges, social visits, schools, and poor hygiene as common sources of infestation, with long-distance buses cited most frequently. Chemical insecticides were the most used control method but were widely viewed as ineffective, leading to the adoption of hot water, paraffin, and home chemical remedies among others. Many expressed frustrations over recurring infestations and the adaptability of bedbugs, prompting calls for government intervention. Psychological impacts were evident, with reports of sleep loss, anxiety, and physical discomfort. Social stigma was also prominent, with infestations often linked to poor hygiene, causing embarrassment, strained relationships, and social withdrawal. Conclusion: Facebook served as a rich source of informal citizen science, offering real-time, community-level insights into bedbug infestation patterns, lived experiences, and coping strategies. In contexts with limited formal data, Facebook-based citizen science can inform responsive, community-centred interventions for public health and surveillance.
