Improved ventilation inside homes and work spaces reduces Covid-19 transmission

According to the new guidelines issued by the Center for the transmission of Corona virus, very important information has been released about the spread of the virus from the air. There is a risk of the virus spreading from the air to other people through the nasal passages.

Places with adequate ventilation and open air are given special importance in the guideline. It has instructed hospitals and other medical centers to take care of air circulation. Also open the vaccination process.

WHO has also said that the role of ventilation is very important for gaining control over the corona. ‘Under the current circumstances, the corona virus is mainly spread among people who come in close contact with each other typically 1 meter or less.

The guidelines also mention that hospitals and health centers must ensure that vaccinations are carried out in well-ventilated and directional air-flow controlled areas.

In closed un-ventilated indoor spaces, droplets and aerosols become quickly concentrated and greatly increase the risk of transmission to people in the area," the guidelines prepared by the principal scientific adviser to the government states.

"Just as smells can be diluted by ventilation, the dangerous concentration of the virus can be reduced by ensuring that outdoor air flows in," it further says.

Avoid placing fans in a way that could potentially cause contaminated air to flow directly to someone else. Installing an exhaust fan is important. Keep exhaust fans running if the windows and doors are shut.

Add an exhaust fan OR turn a pedestal fan into an exhaust fan by turning it to face outdoors, to create the ideal air flow for maximum protection from indoor infection.

It is advised that jaali/air outlets with exhaust fans are installed by gram panchayats in homes where there is no cross-ventilation.

Running ACs while keeping windows and doors shut, traps infected air inside the room, and increases risk of transmission from an infected carrier to others.

Ensure cross flow of air in public transport vehicles and keep windows open in buses and trains where possible, likewise, introduce exhaust systems to improve airflow in air-conditioned buses and trains
