Openability of windows and presence of wire mesh in residences in a New Delhi neighbourhood as a factor of dilution ventilation required for prevention of airborne diseases and vector borne diseases
Raja Singh, Anil Dewan
Abstract
Spread of airborne diseases can be prevented by dilution ventilation, which is possible by increasing fresh air intake. A recommended way to bring in outside fresh air requires operable windows. These windows must have wire-mesh to prevent the entry of insects, flies, rodents and stray animals. A visual examination of 265 house plots was made in a residential area of New Delhi. Out of the 40 built post 2016, 12 had new Poly-Vinyl Chloride-based window/door frames, none of which had a wire mesh. Operability and wire-mesh are important for fresh air intake for dilution ventilation and preventing vector-borne diseases.
