Every week, new information appears on how to transmit and manifest the new coronavirus. The list below contains the most common ways of contracting the new Covid-19.
From the beginning of the pandemic until now, a few things have remained unchanged regarding the new coronavirus. We still know that the most common mode of transmission is respiratory drops. Contact with infected hands is also dangerous, as are clouds of viral particles or aerosols in closed, poorly ventilated areas. If you have become ill with SARS-CoV-2 and are not sure where you got the disease from, you have probably neglected one of the above.
As a reference, in the real world, from the moment you go out and start interacting with various people, it is important to remember that the virus can survive even 9 hours on the skin, compared to the flu that lasts 1.5 hours. If you use an alcohol disinfectant, it would be ideal to rub your hands for 15 seconds to neutralize the virus. On the phone screen, if you haven’t made a habit of disinfecting it, it lasts up to 28 days, according to AFP.
How the new coronavirus is transmitted outdoors and indoors
The first way to transmit the coronavirus identified is through saliva droplets expelled by an infected person while coughing or sneezing, but also when singing or talking. To protect yourself in such situations, it would be good to stay a meter, a meter and a half from the interlocutor.
In such situations it is relevant for two interacting people to wear a mask. The good part is that these drops are relatively heavy and do not remain suspended in the air.
Regarding the hosting of the virus on various surfaces, a lot of information has appeared in the online environment. The virus can also attach to a surface contaminated with drops, such as hands, wipes, glasses, faucets, doorknobs, lift buttons, railings, and more. The risk of contamination occurs if the face is touched after coming into contact with them.
However, “this does not mean that this amount of virus could infect anyone,” said Trevor Drew, director of the Australian Center for Disease Prevention at ABC. The main message remains that “infected people are much more contagious than surfaces.” “However, it may explain why, even when there are no more contagious people, it happens that (the epidemic) returns, even if the country is considered free of viruses,” the researcher added.
The last way to transmit the new coronavirus is through aerosols. In closed, poorly ventilated spaces, aerosols, clouds of microscopic drops of viral particles that are released only by breathing, can travel longer distances and can land directly on other people’s faces in a perimeter of about two meters. It is estimated that these invisible clouds remain suspended in the air for minutes or even hours, depending on the ventilation.
“There is nothing new under the sun when it comes to recommendations. There are three modes of transmission: drops, aerosols and manual, without knowing the relative share of each. Therefore, we must continue all the blocking gestures and open the windows “, Professor Arnaud Fontanet, epidemiologist at the Pasteur Institute, summed up for AFP, after the recent publication of the findings of the Japanese and Australian researches.
