“…As for the indoor environment, now more than ever it is important to address the presence of aeroallergens in homes, as these too are linked to respiratory health. 74 Clinical familiarity with spatiotemporal patterns of aeroallergens and pollutants is therefore advised.…”

The 2020 coronavirus pandemic is developing at different paces throughout the world. Some areas, like the Caribbean Basin, have yet to see the virus strike at full force. When it does, there is reasonable evidence to suggest the consequent COVID-19 outbreaks will overwhelm healthcare systems and economies. This is particularly concerning in the Caribbean as pandemics can have disproportionately higher mortality impacts on lower and middle-income countries. Preliminary observations from our team and others suggest that temperature and climatological factors could influence the spread of this novel coronavirus, making spatiotemporal predictions of its infectiousness possible. This review studies geographic and timebased distribution of known respiratory viruses in the Caribbean Basin in an attempt to foresee how the pandemic will develop in this region. This review is meant to aid in planning short-and long-term interventions to manage outbreaks at the international, national, and subnational levels in the region. K E Y W O R D S coronavirus, pandemic, seasonal incidence Not all seasonal respiratory viruses experience the same spatiotemporal patterns. Nevertheless, assuming seasonality, the only way of predicting SARS-CoV-2 behavior in a given region is to extrapolate data from known pathogens.

“…This frequency of mites was found to be compatible with the rate of 18.6% in general in Turkey [16]. The frequency of house dust mites has been found at the rate of 16.9-90% in studies worldwide [19,20]. House dust mites are the most important allergen that triggers many allergic reactions such as asthma, eczema, and perennial allergic rhinitis.…”

Introduction:The house dust mite is a major cause of allergic disease. The standard diagnostic techniques consist of determination of the immunoglobulin E (IgE) level in blood and the application of a skin prick test. The skin prick test results are not always reliable because only 2 common species are determined by the test. Thus, the prevalence of mite allergy in a population requires microscopic analysis of collected samples. Aim: This cross-sectional study was conducted to investigate whether skin prick test results are compatible or not with the presence of mites in a house. Material and methods: A total of 84 allergic patients were included in the study. A questionnaire was applied to detect allergic risk factors. The skin prick test was performed to ascertain if the allergy occurs due to Dermatophagoides pteronyssinus and D. farinae. Patients were requested to take dust samples from their homes to determine the sensitivity of the prick test. Results: In our study, we have shown that D. pteronyssinus and D. Farinae are the common (32.5%), but not the only species, in dust samples. The frequency of mites was found to be 21.4% in dust samples taken from the homes of these patients, and 17.5% of the house dust mite allergen could not be identified without microscopic examination. In this study, we have clearly shown that humidity and feeding animals increase the dust mite development risk by 1.74 and 1.82 times, respectively. Conclusions: Dermatologists should request dust samples from patients with allergic problems for detailed examination such as microscopy or ELISA.

“…Allergen levels were detected using a two‐site monoclonal antibody‐based enzyme‐linked immunosorbent assay with a Der f 1 and Der p 1 ELISA 2.0 kit (INDOOR, Biotechnologies, Ltd, Manchester UK). Next, the sample extracts (100 µL) were added in triplicate into each plate, and a 10‐point curve was made using sequential twofold dilutions of a known standard in PBS‐T with 1% BSA (Vesper et al 2016 ) . Finally, the samples were read with an optical density plate reader at a wavelength of 450 nm.…”

Dust in the home environment is thought to be a potential trigger for increasing allergic diseases, such as allergic rash, rhinitis, asthma, and other conditions, associated with dust mites. To verify the status of dust mite prevalence in indoor surroundings, we collected 189 dust samples from the air conditioner filters (n = 75) and floors (n = 114) of households, schools, and hotels in the Anhui area, China. All samples were measured for dust mite breeding rate and breeding density under light microscopy and analyzed for dust mite species Dermatophagoides farinae 1 (Der f 1) and Dermatophagoides pteronyssinus 1 (Der p 1) allergen using enzyme-linked immunosorbent assay (ELISA). The dust mite breeding rates were 34.67% (26/75) and 20.18% (23/114), respectively, in the dust samples from the floor and air conditioning filters. The breeding density was the highest in households (10/g), followed by schools (9/g) and hotels (4/g). ELISA indicated that the allergen threshold (2.0 µg/g dust) of Der f 1 was exceeded in only two samples and Der p 1 in one sample. Additionally, a questionnaire was used to investigate the health knowledge on allergic diseases involved in indoor facilities, finding that most allergy sufferers were aware that indoor dust might be responsible for their conditions. The findings suggest that regular maintenance of indoor hygiene and cleaning of air-conditioning filters should reduce the risks of exposure to indoor allergens.
