“…In countries of the tropical and subtropical climate zones there are no clear seasonal variations in the incidence of scabies, as confirmed by data from Brazil, Gambia, Malawi and Taiwan [31,32,33,34]. This phenomenon may result from the fact that in the countries where seasonal changes were observed the climate shows clear division into seasons, unlike in the countries of tropical and subtropical climate zones, where during the year there is a positive heat balance with a slowly changing temperature gradient.…”

Introduction. Scabies is a contagious parasitic disease, a skin infestation caused by Scaroptes scabieri, tiny mites that burrow under the skin. Outbreaks of scabies can be difficult to control and require the implementation of appropriate control programme. Objective. The purpose of the study was to analyze the epidemiology of scabies in northeast Poland, considering socioeconomic and selected climatic factors. Materials and method. The analysis was based on data reports (n=26,362) obtained from the Polish National Health Fund (NFZ) for the period 2007-2014. Monthly climate data were collected from the Institute of Meteorology and Water Management/National Research Institute (IMGW-PIB) in Warsaw, including data on temperature and relative humidity. Additionally, the influence of socioeconomic factors on the prevalence of scabies was analyzed. Data on population size, medical staff, and unemployment rate were obtained from the Central Statistical Office (GUS) in Warsaw, and analyzed using SPSS Statistics 24.0 programme. Results. The age group of 10-19 years showed the highest infestation rates. Seasonality of scabies was demonstrated. The highest numbers of cases were reported during the autumn and winter months. There was a significant negative correlation (rho =-0.499; p<0.001) between air temperature and the incidence of scabies, and a positive correlation (r = 0.532; p<0.001) between relative humidity and the number of cases reported. A rise in the unemployment rate also caused an increase in the scabies incidence rate (r = 0.294; p<0.001). Conclusions. The results suggest that an improvement of socioeconomic conditions may contribute to a reduction in the number of scabies infections. The possibility should be considered of monitoring the parameters, such as air temperature and humidity, particularly when scabies outbreaks occur.

“…The current study agreed with study of Maizels et al (2005) that showed a significant increase in the serum level of total IgE in patients infected with helminthes parasite infections and allergic diseases in compared to control group. The results of study showed a significant increase in the serum level of MCP-1 in male and female patients infected with Sarcoptes scabiei parasite compared to control group, also in total patients with S. scabiei compared to the total control group, this increase may be due to interaction between the human immune response and S. The results of study showed a significant increase in the serum level of IL-17 in male and female patients infected with Sarcoptes scabiei parasite compared to control group, also in total patients with S. scabiei compared to the total control group, this increase may be due to hypersensitivity reactions in patients infested with scabies caused by the secretion of different materials by S. scabiei in the host skin (McCarthy et al, 2004;Hengge et al, 2006;Liu et al, 2016; Aljanaby and Medhat 2017). During 4 weeks from infestation of scabies the immunity developed and appears of first symptom (Walton et al, 2008).…”

The current study is trying to identify some effects of scabies on some vital indicators such as (ECP, IgE, MCP-1 and IL-17). The results showed that levels of ECP has significant increase (P<0.05 (9569.3 ±256.10 pg /ml), (9872.9± 260.50) respectively in comparison with the control group (7665.2 ± 385.72 pg /ml), (7834.1± 251.43 pg /ml) respectively, The result proved that there was the significant increase (P (9721.1 ±181.15 pg /ml), (7749.7± 226.75) respectively in concentration of (ECP) in patients with S. scabiei and total healthy individuals. The levels of IgE had significant increase (P (284.8 ±34.05 IU / ml), (249.85± 13.682 IU /ml) respectively in comparison with the control group (119.5 ± 11.24 IU /ml), (108.77± 8.3 IU /ml) respectively. The result indicate that there was significant increase (P (267.134 ±18. 334 IU /ml), (114.13± 6.94 IU /ml) respectively in concentration of (IgE) in total patients infected with S. scabiei and total control group. The levels of MCP-1 has significant increase (P (271.76 ±29. 88 pg /ml), (246.983± 27.57 pg /ml) respectively in comparison with the control group (153. 27 ± 21.071pg/ml), (154.67± 22.973 pg /ml) respectively, Also it revealed the significant increase (P (259.29±20. 22 pg /ml), (153. 97± 15.21 pg /ml) respectively in concentration of (MCP-1) in S. scabiei patients and total healthy individuals. IL-17 had significant increase (P (16.318 ±0. 71 pg /ml), (16.847± 0.58 pg /ml) respectively in comparison with the control group (5. 6009 ±0. 45 pg/ml), (5.2023± 0. 35 pg /ml) respectively. The current study shows that there was significant increase (P (16.583±0. 45pg /ml), (16.4016± 0.28 pg / ml) respectively in concentration of (IL-17) in total patients infected with S. scabiei and total healthy individuals. The levels of IL-2 had significant increase (P (21.14 ±0. 8081 pg /ml), (21.800± 1.0644 pg / ml) respectively in comparison with total healthy individuals (7. 447 ±0. 2422 pg/ml), (7.7235± 0. 1716 pg /ml) respectively, Also it revealed the significant increase (P (20.972±0. 6626pg /ml), (7.5853± 0.1480 pg /ml) respectively in concentration of (IL-2) in total patients infected with S. scabiei and total control group. Conclusions: the results indicate that infection of scabies influences on the human immunity represented by the ECP, IgE MCP-1 and IL-17 in patients infected with scabies and may be used as good biomarkers in detection of scabies.

“…We can explain the result of this study, is may be due to contact between married men and women in same family lead to transfer this mite during sexually contact from husbands to wives. Climate is one of the most important factors that play an important role in scabies incidence worldwide [24]. Iraq is a tropical country characterized by high temperature between 30°C to 40°C throughout the year.…”

The aim of the current study was to epidemiological detection of patients infected with scabies caused by Sarcoptes scabiei during the period from March 2017 to February 2018 in Iraq, Al-Najaf Governorate.A total of 1112 patients were infected with scabies, 602 (54.1%) were men and 501 (45.9%) were female and 419 patients (37.7%) were lived in urban areas and 693 patients (62.3%) were lived in rural areas. Age group 31-40 y old was the most prevalent group (379 patients, 34%) infected with scabies. February 2018 was the highest month in infection (187 patients, 16.8%) and May 2017 was the lowest month in infection (25 patients, 2.2%). In conclusions: In Iraq, there are high numbers of individuals infected with scabies without any health care especially in rural areas. Scabies is more prevalent in cold and warmth seasons in males as well as females among age group 30-40 y old. Therefore, scabies is still an important health problem in Iraq as a neglected disease.
