“Based on our study, we recommend that furniture in hospitals and offices, made of impermeable material, such as glass, stainless steel, or laminated wood, be covered with a porous material, such as cloth, to reduce the risk of infection upon touch,” said study author Sanghamitro Chatterjee from IIT Bombay.
It also suggests that the seats in public places like in shopping malls, restaurants and railway stations and airport waiting should be covered with cloth for reducing the spread of infection.
It was also found that 99.9 per cent of the droplet’s liquid content on both impermeable and porous surfaces evaporated within the first few minutes. The thin residual film remains on the exposed solid parts, where the virus can still survive.
The evaporation of the remaining thin film is much faster in the case of porous surfaces as compared to impermeable surfaces.
This makes cardboard boxes used for deliveries a safer option as they would inhibit virus survival. And people should clean surfaces like plastic and steel more often.
