New research shows that New Coronavirus’s ability to contact and spread is equally important

Novel Coronavirus is unlikely to spread through a surface and droplets are still the primary means of transmission, so measures such as wearing a mask and maintaining social isolation are still necessary, according to CDC.
But a new study from University College London took samples of viral DNA from tests placed on the handrails of hospital beds in isolation rooms.
They found that within 10 hours, viral DNA covered 41% of the sampled area of the ward.

This study shows how easily pathogens can move between surfaces, thus highlighting the importance of personal hygiene and protective gear during the novel Coronavirus pandemic.

After all, when a carrier is talking, it is likely to produce smaller droplets.
If you cough or sneeze, the droplets will get bigger and bigger.

The virus can then spread on a variety of surfaces, a major reason health authorities are urging people to wash their hands more often and avoid touching public objects.

44 sites were sampled daily and the proportion of positive tests in the total/different areas was determined.

Although the risk of contact transmission is not as high as droplets, the risk remains.
If a novel Coronavirus accidentally touches the eye, nose or mouth after touching the virus surface, it is still possible to be infected by avirus.

Previous studies have shown that the virus can live for hours or days in the air and on certain surfaces.
Now the new study shows that viral DNA can spread widely in hospital wards.

Full sampling within 10 hours showed that almost half of the virus’S DNA remained in hospital beds, even for five days.
Fortunately, the virus selected for study is not the live virus strain from novel Coronavirus.

The CDC released its guidelines on May 11

The team copied a portion of DNA from a plant-infected virus that does not infect humans and immersed it in a solution of 0.1ml, the same concentration as SAV-COV-2.

After 10 hours of smearingthe “tested object” on the bed bars of the isolation room, viral DNA has been found on doorknobs, waiting-room deputies, and even toys and books in children’s play areas.
The researchers detected viral DNA in 41 percent of the sample area, then 52 percent within three days, and then 41 percent on the fifth day.

In addition to the emphasis on good personal hygiene, said study senior author Lena Ciric, Ph.D., “While one sample is frequently touched by staff, patients, and visitors in one location, novel Coronavirus patients will also spread the virus to more places through coughing, sneezing, touching surfaces and more.”
