“…This indicates that the Permethrin 1% treatment effectively eradicates Pediculosis capitis (Maryanti & Lestari, 2020). Further, this also indicates that the residents adhered to our instruction to repeat the treatment on days 7 and 14, maintain their hygiene, keep their hair clean, and cease towel and hair combs sharing behaviour (Castelletti & Barbarossa, 2020;Ganesan, H., & Damayanti, P. A. A, 2017;Gharsan et al, 2016;Maryanti & Lestari, 2020).…”

Children living in orphanages are generally vulnerable to close-contact transmission diseases, including head lice infestation. The clinical manifestation of head lice infestation was relatively mild, such as itchy scalp, and hence it is often overlooked as a community health issue. Education plays an essential role in preventing re-infection and eradicating head lice infestation. The treatment options include chemical treatment using pediculicides and physical management by shaving the head and manually removing the parasite. This community service activity aimed to eradicate head lice from Yayasan Griya Asih Orphanage. A series of three activities were conducted at Yayasan Griya Asih Orphanage in Central Jakarta. Each activity was done around one month apart to evaluate the effectiveness of treatment. Firstyear medical students were recruited to participate in these activities to familiarize them with real-world community health problems. Student volunteers helped applied pulse doses of Permethrin 1% shampoo and provided health education activity. Fiftyfive Yayasan Griya Asih Orphanage residents joined this activity from mid-October until December 2022. Residents were instructed not to share their personal items to prevent re-infection. Health education activities were done using one-to-many followed by a one-on-one format. In conclusion, head lice infestation screening is essential in crowded environments, and permethrin 1% pulsed dose followed by personalized health education activities and pest control effectively broke the disease transmission chain and eradicated the head lice infestation.

“…Infected and non-infected populations interact in three ways: 1) by horizontal transmission (when a non-infected individual becomes infected (Ebert 2013), 2) by clearing (when an infected individual becomes non-infected), and 3) competition between individuals of the two populations. Implementing the interactions in the structured model results in high-dimensional systems with limited analytical tractability (Castelletti and Barbarossa 2020; Tian et al 2018). To avoid these difficulties, we assume continuous-time population dynamics with the Malthusian growth rates derived from the structured model.…”

The coevolution of hosts and symbionts based on virulence and mode of transmission is a complex and diverse biological phenomenon. We introduce a conceptual model to study the stable coexistence of an obligate symbiont (mutualist or parasite) with mixed-mode transmission and its host. The existence of evolutionarily and ecologically stable coexistence is analyzed in the framework of coevolutionary dynamics. Using an age-structured Leslie model for the host, we demonstrate how the obligate symbiont can modify the host's life history parameters (survival and fecundity) and the long-term growth rate of the infected lineage. The evolutionary success of the symbionts is given by the long-term growth rate of the infected population (multi-level selection). When the symbiont is vertically transmitted, we find that the host and its symbiont can maximize the long-term growth rate of the infected lineage. Moreover, we provide conditions for the ecological and evolutionary stability of the resident host-symbiont pair in the coevolutionary model, which does not allow invasion by any rare mutants (each mutant dies out by ecological selection). We observed that ecological competition, clearing of infection, and density-dependent interactions could play a role in determining the criteria for evolutionary stability.

“… 8 , 10 Usually, a minute amount of saliva from the louse with anticoagulant and vasodilatory properties is inoculated into the scalp with each blood meal, thereby facilitating the sucking of the host’s blood. 2 , 11 , 12 Without blood meals, head lice can normally survive for up to 55 hours away from the human host, 13 , 14 although they may live for up to 4 days in favourable conditions. 1 Lice eggs, on the other hand, can survive for up to 10 days off the human body.…”

Background Pediculosis capitis is a common human parasitic infestation in childhood. This article aims to provide a narrative updated review on the management of pediculosis capitis. Methods A PubMed search was performed with Clinical Queries using the key terms “pediculosis capitis” OR “head lice” OR “head louse”. The search strategy included clinical trials, meta-analyses, randomized controlled trials, observational studies and reviews published within the past 10 years. The search was restricted to articles published in English literature. The information retrieved from the search was used in the compilation of the present article. Results Topical permethrin and pyrethrin formulated with piperonyl butoxide are the pediculicides of choice in areas where resistance to these products is low. When resistance to these products is suspected based on local levels of resistance or when treatment with these products fails despite their correct use, and reinfestation does not seem to be responsible, other topical treatment options include malathion, benzyl alcohol, dimethicone, spinosad and ivermectin. Wet combing should be considered for children younger than 2 years. Oral ivermectin and trimethoprim/sulfamethoxazole should be reserved for patients who do not respond to appropriate topical pediculicides. Conclusion Many topical pediculicides are effective for the treatment of pediculosis capitis. The use of some of these pediculicides is limited for safety reasons, especially in children younger than 2 years. Resistance to pediculicides, especially those with a neurotoxic mode of action, is another concern which may limit the use of some of these pediculicides. New products should be evaluated for effectiveness and safety. Wet combing is time-consuming and should not be used as the sole intervention in the general population.
