There are five ways to avoid indoor infections - collected

Good ventilation is needed to prevent coronavirus infection indoors. In many lands the cold season is approaching, when people prefer to keep doors and windows closed to keep their homes warm. But it is very important to have a good ventilation system.

In the last few months, scientists have been urging people to wash their hands and maintain social distance to prevent coronavirus. Now scientists, as well as engineers, say it's time to think about the air we breathe. People are starting to travel again in most places, especially after the lockdown has eased. Office courts, school colleges, shops and restaurants are slowly starting to open.

One.

If you enter a room and think that the air there is stale, stale, then assume that the air in that room does not circulate. If you do not breathe outside in a house, your risk of getting coronavirus infection will increase.

Recent studies have shown that there is a risk of 'airborne infections' from the virus in closed rooms. Even if the tiniest particles of the virus remain in the air. Even before the epidemic, government guidelines on workplace ventilation in Britain said it was mandatory to have a workplace system that provided 10 liters of clean air per worker per second. It is now very important to comply with the epidemic situation.

So, if a house seems closed, there seems to be a lack of open air, get out of that house, says the expert engineer. Highwell Davis. "Suppose someone is infected in the building where you are, and if you inhale a lot of clean air from outside, the elements that have spread the virus into the air will weaken a lot by mixing with the air," he said. Breathing in that air will reduce the risk of infecting others. '

Two.

Air conditioning is now available everywhere from offices to shops. People welcome it on hot days. But look at what kind of air conditioning device is being used. The most commonly used is the split model air conditioner mounted on the wall or roof. Such an air conditioner draws air out of the house, cools it, and releases the air back into the room. That is, such an air conditioner replenishes the air.

There is no reason to worry if the air conditioning device is used for a short time in the room. However, since there is a risk of long-term cuts, it is best to look at what type of equipment is being used.

A study conducted on a restaurant in China has blamed such air-conditioning devices for spreading the virus. Their study found that the man who came to the restaurant had the virus in his body, he was infected, but he did not know because even then his symptoms did not appear. Scientists believe he released the virus into the air with his breath as he spoke, and a wall-mounted air-conditioning device pulled the virus and spread the infected air throughout the restaurant room. As a result, nine more people who went to eat at the restaurant were infected.

According to the study. Davis again says it is very important to have clean outside air circulation in the room. If there was a lot of outside air circulation in the house, very few people would be infected there - maybe no one would be infected.

Three.

In many modern buildings the windows are permanently closed, there is no system to open the windows. So how will the outside air enter in those cases? In that case you have to rely on the ventilation system through which the polluted or trapped air of the house will be brought out and that air will go through the pipe and go to an outside air circulation unit. Usually this unit is on the roof of such a building.

This unit draws clean air from the outside and mixes it with the stale air inside and then sends that mixed air back into the house. Against the backdrop of the risk of being infected with coronavirus from indoor air, experts recommend that there be adequate indoor fresh air.

Kath Knox, a professor at the University of Leeds in England and a member of the British Government's Scientific Advisory Council on Emergency Issues, said it was best to keep the outside air at 100 per cent. The more clean air comes from outside, the more inside your building
