Sensitivity of airborne transmission of enveloped viruses to seasonal variation in indoor relative humidity
نویسندگان
چکیده
In temperate climates, the peak in infection rates of enveloped viruses during winter is likely heightened by seasonal variation relative humidity within indoor spaces. While these trends are established influenza and human coronaviruses, mechanisms driving this seasonality remain poorly understood. Relative impacts evaporation rate equilibrium size airborne particles, which turn may impact particle removal virion viability. However, importance two processes not known. Here we use Quadrature-based model Respiratory Aerosol Droplets to explore whether driven differences or inactivation rates. Through a large ensemble simulations, found that dry conditions typical lead slower than humid summer; ventilated spaces, reduction increases concentration active virions, but effect was important exposure only when susceptible person farther 2 m downwind infectious person. On other hand, on settling velocity did significantly affect travel distance virus-laden suggesting more transmission via removal.

The use of aerosolized bacteriophages as surrogates for hazardous viruses might simplify and accelerate the discovery of links between viral components and their persistence in the airborne state under diverse environmental conditions. In this study, four structurally distinct lytic phages, MS2 (single-stranded RNA [ssRNA]), ϕ6 (double-stranded RNA [dsRNA]), ϕX174 (single-stranded DNA [ssDNA]),...
متن کاملIndirect health effects of relative humidity in indoor environments.
A review of the health effects of relative humidity in indoor environments suggests that relative humidity can affect the incidence of respiratory infections and allergies. Experimental studies on airborne-transmitted infectious bacteria and viruses have shown that the survival or infectivity of these organisms is minimized by exposure to relative humidities between 40 and 70%. Nine epidemiolog...

PURPOSE We previously demonstrated seasonal variation in sensitization to aeroallergens in a small group of patients with exercise-induced asthma. This study was performed to confirm the relationship in a much larger population. METHODS The charts of 1,891 patients who received allergy skin prick tests were reviewed retrospectively. The test results from subjects aged ≤60 years were compared ...
