Airborne SARS-COV-2, ventilation is the solution (E)
"Till recently scientists believed that the SARS-COV-2 virus that causes the Covid-19 disease travels and transmits mostly through droplets and cannot travel far. Recent evidence, however, suggests that the virus could travel up to 10 meters riding on aerosols. This evidence was first collected in India by scientists of the Council of Scientific and Industrial Research (CSIR). Due to the diligent work by Indian scientists, there is increased discussion that indoor transmission of the Covid-19 infection can be reduced if ventilation especially air circulation is improved. Merely opening windows and doors can cut the risk of transmission. This has major implications on how air-conditioned buildings are ventilated. Masks remain the most important tool to control the infection. Newer solutions like ultra-violet light disinfection of air offer some promise. New buildings also need to be designed incorporating the up to date ventilation codes as suggested by the CSIR- Central Building Research Institute, Roorkee. Dr Shekhar C Mande, Director General, Council of Scientific and Industrial Research (CSIR), New Delhi asserts better airflow can cut down the risk of most airborne infections, not just Covid-19. "
