GoI issue Advisory to “Stop the transmission”, obey COVID norms can prevent from the spread of SARS-CoV-2 virus
The Scientific Adviser of the Government of India has issued hassle-free guidelines to “Stop the transmission, crush the pandemic by wearing the mask, maintaining distance, sanitation and ventilation to prevent the spread of SARS-CoV-2 virus”. As the pandemic rages in India, we need to once again remember that simple tools and practices can reduce the spread of the SARS-CoV-2 virus, an official said.
The advisory highlighted the important role well-ventilated space play in diluting this viral load of infection air in the poorly ventilated house, office, etc. Ventilation can decrease the risk of transmission from one infected person to another.
Ventilation is a community defense that protects all of us at home or at work. Introducing outdoor air in offices, homes and larger public spaces is advised. Measure to improve ventilation in these spaces must be taken up on urgent priority in urban priority in urban and rural areas alike, recommendations for hutments, homes, offices and large centralized buildings are given. Simple strategic placement of fans, open windows and doors, even slightly open windows can introduce outdoor air and improve the air quality inside. Introducing cross ventilation and exhaust fans will be beneficial in curtailing the spread of the disease.
In a building with a central air-management system and roof, ventilation are recommended. Frequent cleaning and replacement of filters are highly recommended.
Saliva and nasal discharged in the form of droplets and aerosols, by an infected person while exhaling, talking, speaking, singing, laughing, coughing or sneezing etc, is the primary mode of virus transmission. An infected person who shows no symptoms also transmits the virus. People without symptoms can spread the virus. People should continue wearing a mask, wear double masks or N95 masks.
The SARS-COVID-2 virus infects a human host where it can multiply, in the absence of the host it cannot survive and stopping the transmission of the virus from a person to another person will decrease the infection rate of the disease to a level where it can eventually die. This can be achieved only with the support and cooperation of individuals, communities, local bodies and authorities. Use of mask, ventilation, distancing and sanitation, the battle against the virus can be won.
