WHO warns Corona virus can be transmitted through the air

Corona virus can live for three days on several surfaces of objects such as plastic and iron, said the latest research. Experts say the risk of consumers infected with the corona virus from touching objects is still low. But experts warn about how long the virus can survive in the air and it could have an important effect on medical officials.Recent research published yesterday in the New England Medical Journal also says the corona virus can be destroyed in one day if it is in a cardboard box. That at least reduces people’s concern that the spread of the virus can still occur when they are quiet or working from home.

When the virus is splashed smaller than 5 micrometers – called an aerosol it can last for 30 minutes, researchers say, before finally landing on the surface of the object and then it can last for several hours. The discovery of aerosols is contrary to information from the World Health Organization (WHO) which says the virus cannot be transmitted from the air.

Plastic and iron

Therefore WHO is warning medical staff about the corona virus which can be transmitted from the air.”When you do the procedure using aerosols as in medical activities, you have that possibility, meaning the virus can stay in the air a little longer,” said Dr. Maria Van Kerkhove, head of the WHO Unit for Developing Diseases and Zoonoses.”It is important for medical staff to take precautions when they treat patients,” he said.Reporting from the New York Times page, Wednesday (3/18), the corona virus can survive longer on the surface of plastic and iron, can be up to 72 hours. But the amount of this virus dropped dramatically when it was more than 72 hours. Likewise on the surface of copper, this virus can survive four hours. In a corona virus box can last for 24 hours it means the package sent with cardboard packaging can be low risk of exposure to the virus – unless the person who sent the package sneeze or cough about the package or his hands have been contaminated with the virus.

Clean the package with disinfectant

The risk of contracting various objects is low, experts say, unless the person holding the object is sick.”All items in supermarkets and restaurant food bags can theoretically infect people,” said Dr Lindsay Marr, who is not a member of the research team but an expert in aerosol virus transmission at Virginia Tech Blacksburg.”We can go crazy discussing ‘what if’ because everyone has the potential to become a source of transmission so we have to focus on the biggest risks.”

If people care about that risk then they can clean the package with a disinfectant cloth and wash their hands, he said.It is still unclear why cardboard as a place where the virus can not last longer than plastic and iron, but there is a possibility can be explained by the quality of absorption of cardboard material compared to the other two materials.

Maintain a distance

Viruses that can survive in aerosols (liquid spray or gas) are also important influences for health workers.For several weeks experts thought the corona virus could not be transmitted through the air. But it turns out this virus can fly in the air and survive for some time, about half an hour.This virus cannot survive in the air at a level that can transmit people who are physically far away from infected people. But health workers must treat patients at close range and can be infected with aerosols.”All of these treatments can trigger transmission from aerosols and sparks.”

Study in Singapore

Medical personnel can also be contaminated with splashes and larger liquids that stick to their protective clothing when handling patients. They can also make the virus splash in the air when removing protective clothing and they can be exposed, said Dr. Marr.The results of this study are quite frightening. And other research published on March 4 also suggests the virus can move through the air. Dr Marr said that based on physics aerosols can be sprayed from a height of 1.8 meters and will fall to the ground after 34 minutes. This finding does not have to make people panic, because the virus can break down quickly in the air.

“Sounds scary, but the possibility of you getting it is very small unless you are close enough to someone who is infected.”Dr Marr gives a picture of someone who smokes or sighs in cold weather. The closer and faster people breathe the air of cigarette smoke or breathing, the more easily they can be infected, but for people who are quite far away, for example, about a few meters, the less likely the virus in the air can be dangerous.Dr Munster said, in general, this new corona virus did not seem to be able to survive longer than its previous close relatives such as SARS and MERS which also caused epidemics. That indicates there are other reasons, such as transmission from people who have no symptoms but can cause a pandemic.
