Integrated approaches to mapping skin Neglected Tropical Diseases (NTDs) may be cost-effective way to guide decisions on resource mobilization. Pilot studies have been carried out, but large-scale data covering multiple countries endemic for skin NTDs are lacking. Within the LAMP4YAWS project, we collected integrated data on the burden of multiple skin NTDs. From March 2021 to March 2023, integrated case searches for yaws alongside other skin conditions were performed in endemic health districts of yaws in Cameroon, Côte d'Ivoire, and Ghana. Integrated activities included training, social mobilization and active case detection. Initial screening involved a brief clinical examination of participants to determine if any skin conditions were suspected. Cases of skin NTDs were then referred to a health facility for appropriate management. Overall 61,080 individuals screened, 11,387 (18. 6%) had skin lesions. The majority of individuals (>90%) examined were children aged 15 years old and under. The proportion of serologically confirmed yaws cases was 8. 6% (18/210) in Cameroon, 6. 8% (84/1232) in Côte d'Ivoire, and 26. 8% (440/1643) in Ghana. Other skin conditions based on clinical examination included: scabies, Buruli ulcer, leprosy, lymphatic filariasis (lymphoedema and hydrocele), tungiasis, and fungal infections. The most common conditions were scabies and superficial fungal infections. In Cameroon, scabies and superficial fungal infections accounted for 5. 1% (214/4204) and 88. 7% (3730/4204) respectively, 25. 2% (1285/5095) and 50. 4% (2567/5095) in Côte d'Ivoire. In Ghana, 20% (419/2090) of individuals had scabies but superficial fungal infections were not routinely recorded and were reported in only 1. 3% (28/2090). Other skin NTDs were less common across all three countries. This study confirms that integrated screening allows simultaneous detection of multiple skin NTDs, maximising use of scarce resources. Many Neglected Tropical Diseases (NTDs) predominantly affect the skin and are referred to as skin NTDs. The World Health Organization (WHO) has developed a number of strategies for the control, eradication and elimination of skin NTDs and recognizes the importance of integrated approaches to mapping skin NTDs. We conducted a study adopting integrated screening for multiple skin NTDs and other skin conditions in Cameroon, Côte d'Ivoire, and Ghana. This ran alongside a study focused on diagnostic tests for one specific skin NTD-yaws. The results showed that integrated screening is a feasible and cost-effective way to detect multiple skin NTDs in a single intervention. Of more than 60,000 individuals screened almost one in five had a skin lesion. Cases of yaws confirmed by blood tests were detected more frequently in Ghana compared to Côte d'Ivoire and Cameroon. The most common skin conditions were scabies and superficial fungal infections. Other skin NTDs such as Buruli ulcer, leprosy, lymphatic filariasis and tungiasis were less common. Integrated screening allowed detection of skin conditions and co-endemicity of skin NTDs and the data can guide decisions on resource mobilization to manage skin NTDs. |
