New Study: Coronavirus FOUND in Air Samples up to 4 meters(13ft) From Patients.

Ayon sa mga isinagawang pag-aaral ng mga dalubhasa, ang coronavirus o covid-19 ay matagal na mabubuhay sa mga bagay na madapuan nito, tulad ng karton, steel, plastic at marami pang iba.

Nakakabahala dahil sa mabilisang pagtransmit nito sa mga tao, nalaman din na pwede palang mag stay sa hangin ng 30 minutes to 3 hours ang virus, at ngayon sa bagong pag-aaral nakita na ang virus sa isang hospital mula sa ward ng pasyente ay kakalat hanggang 13 feet o 4 meters.

Kaya araw-araw ay marami na ring naitalang mga frontliners at kadalasan mga doctor at nurses na infected na rin sa virus.

A new study examining air samples from hospital wards with COVID-19 patients has found the virus can travel up to 13 feet (four meters) — twice the distance current guidelines say people should leave between themselves in public.

The preliminary results of the investigation by Chinese researchers were published Friday in Emerging Infectious Diseases, a journal of the US Centers for Disease Control and Prevention (CDC).

They add to a growing debate on how the disease is transmitted, with the scientists themselves cautioning that the small quantities of virus they found at this distance are not necessarily infectious.

The researchers, led by a team at the Academy of Military Medical Sciences in Beijing, tested surface and air samples from an intensive care unit and a general COVID-19 ward at Huoshenshan Hospital in Wuhan. They housed a total of 24 patients between February 19 and March 2.

They found that the virus was most heavily concentrated on the floors of the wards, “perhaps because of gravity and airflow causing most virus droplets to float to the ground.”

High levels were also found on frequently touched surfaces like computer mice, trashcans, bed rails and doorknobs.

“Furthermore, half of the samples from the soles of the ICU medical staff shoes tested positive,” the team wrote. “Therefore, the soles of medical staff shoes might function as carriers.”

The team also looked at so-called aerosol transmission — when the droplets of the virus are so fine they become suspended and remain airborne for several hours, unlike cough or sneeze droplets that fall to the ground within seconds.

They found that virus-laden aerosols were mainly concentrated near and downstream from patients at up to 13 feet — though smaller quantities were found upstream, up to eight feet.

Encouragingly, no members of the hospital staff were infected, “indicating that appropriate precautions could effectively prevent infection,” the authors wrote.
