“…The results were consistent with those of previous studies 6 . Studies have also reported that house dust mites were the most common aeroallergen in many Asian countries 7,13 . Another study also reported a high prevalence of 90% in Taiwan for house dust mite allergies.…”

Background: The proportion of the population with allergic diseases has increased rapidly in recent decades. Studies on the prevalence of allergens contribute to the treatment and prevention of allergic diseases. Although many studies have been published on the prevalence of allergens in China, there are limited studies on the geographic distribution of allergens. Objective: The aim of this study was to explore the prevalence patterns of sensitization to allergens among patients with allergic diseases in all the seven geographic regions of mainland China. Methods: A large epidemiological study was conducted on the prevalence patterns of serum allergen-specific IgE (sIgE) sensitization to the four most common food allergens and five aeroallergens among 44156 patients with allergic symptoms from 2015 to 2018. The data were analyzed using the chi-square test, and descriptive statistics, forest plots and geographic heatmaps. Results: First, house dust mites were the allergen with the highest prevalence of sensitization in all seven regions, with the highest in South China (40.79%) and the lowest prevalence in Northeast China (11.21%). The prevalence of allergens varied in different regions and seasons. Second, the prevalence of sensitization was significantly higher among male than female subjects. Third, except for egg whites and milk, which had the highest positive rates in children, sensitization to other allergens tended to be the highest in teenagers and young adults. Conclusions: Our findings could help clinical staff apply effective treatment to unique patient groups and direct researchers to conduct deeper studies on the epidemiology of allergic diseases.

“…Although the United States and China have similar longitudes and latitudes, which means that they may have similar climates, the populations of these regions have different genetic makeups. Therefore, genetic predisposition may also explain the difference in the prevalence of house dust mites 13 .…”

Epidemiological studies have shown a rise in the prevalence of allergic diseases in India during the last two decades. However, recent evidence from the Global Asthma Network study has observed a decrease in allergic rhinitis, asthma and atopic dermatitis in children. Still, with a population over 1.3 billion, there is a huge burden of allergic rhinitis, asthma and atopic dermatitis, and this is compounded by an unmet demand for trained allergy specialists and poor health service framework. There is wide variation in the prevalence of allergic diseases between different geographical locations in India, and the reasons are unclear at present. This may at least in part be attributable to considerable heterogeneity in aero-biology, weather, air pollution levels, cultural and religious factors, diet, socioeconomic strata and literacy. At present, factors enhancing risks and those protecting from development of atopy and allergic diseases have not been well delineated, although there is some evidence for the influence of genetic factors alongside cultural and environmental variables such as diet, exposure to tobacco smoke and air pollution and residence in urban areas. This narrative review provides an overview of data from India regarding epidemiology, risk factors and genetics and highlights gaps in evidence as well as areas for future research.

“…House dust mite (HDM) is one of the most important and first suspected allergen in the house dust that has great medical importance (Colloff, 2009). HDM's are the microscopic creatures that are found in those habitats which are more closely associated with a man like a bed, bed linens, sofas, clothing, curtains, window sills, floors and carpets and they feed upon dead skin scales shed by human beings (Dey et al, 2014(Dey et al, , 2016(Dey et al, , 2018(Dey et al, , and 2019. Numerous abiotic factors such as temperature, relative humidity and rainfall play determinant role in maintaining the population of mites.…”

Role of Abiotic Factors on House Dust Mite Population: Control and Allergen Avoidance - A Review Article

House dust mites (HDM’s) are an important source of indoor allergens in the house dust and cause various kinds of allergies. They are strongly influenced by abiotic factors such as temperature, relative humidity and seasonal variations. HDM’s are present in houses all over the year but their number varies in different seasons and habitats. The moderate environmental temperature, high relative humidity and adequate food sources are the key factors for their proliferation. The season has a great effect on the mite population. In the rainy season, moderate temperature and high relative humidity are the favorable conditions for the growth of mites, and the population of mites reaches a peak level. Whereas, high temperature and low relative humidity during summer season significantly reduce the mite population level and in the winter season, fall in temperature will drastically reduce the mite number because mites perish due to chilling. Relative humidity of a particular place plays an important role in the growth of mites. By controlling the relative humidity of a particular place, the HDM allergens can be reduced in that place. The prevalence of these mites and their allergen content vary within the locations in the home. Mattresses, carpets, sofas are the main reservoir of HDM’s, as the dust and shed skin scales accumulate in these places and provide abundant nutrition to dust mites. To reduce the allergen content from houses, frequent cleaning and vacuuming of mattresses and pillows, the use of encasement should be advised for allergic subjects.
