Scabies In Resource-Poor Communities In Nasarawa State, Nigeria: Epidemiology, Clinical Features And Factors Associated With Infestation

Epidemiology and clinical features of scabies remain largely unknown in Nigeria's rural communities. To fill this gap, we performed a cross-sectional study in three rural communities in north central Nigeria. A total of 500 individuals were included and examined for scabies infestation; a questionnaire was applied to collect socio-demographic and behavioral data. Scabies was diagnosed in 325 (65.0%) participants. Excoriations (68.6%), vesicles (61.8%), and papules (58.8%) were common skin lesions. Itching was the most common symptom (77.5%); 64% complained of sleep disturbances. Lymphadenopathy was identified in 48.3%. Lesions were most commonly encountered on the abdomen (35.5%), inguinal area (19.1%), and interdigital spaces (14.2%). Poverty-related variables, such as illiteracy (OR: 7.15; 95% CI: 3.71-13.95), low household income (7.25; 1.19-88.59), absence of a solid floor inside house (12.17; 2.83-52.34), and overcrowding (1.98; 1.08-2.81) were significantly associated with infestation. Individual behavior, such as sharing of beds/pillows (2.11; 1.42-3.14) and sharing of clothes (2.51; 1.57-3.99), was also highly significantly associated with scabies. Regular bathing habits (0.37; 0.24-0.56) and regular use of bathing soap (0.36; 0.21-0.53) were protective factors. Scabies is extremely common in the communities under study and is associated with considerable morbidity. The disease is intrinsically linked with extreme poverty.
