A study in Wuhan, China, identified genetic material of the new coronavirus in air-borne suspensions, or aerosols, in medical facilities and public spaces. The finding strengthens the value of extensive sterilization of infection hotspots, excellent ventilation, and avoidance of crowding.
To date, researchers have developed 3 methods which extreme intense breathing syndrome coronavirus 2 ( SARS– CoV-2)– the virus that triggers coronavirus illness 19 (COVID-19)– can be transmitted:
- inhalation of liquid droplets from the coughing or sneezing of a person with the infection
- close contact with an individual who has the infection
- contact with surface areas that contain the infection
According to a current study in China, aerosols might use a fourth transmission path for the virus.
Aerosols are airborne particles that determine around 1 micrometer (one-thousandth of a millimeter) in size at most. Because they are much smaller than droplets, they stay suspended in the air for longer and can travel farther.
In their study, the researchers detected genetic product, RNA, of the infection in aerosols tested from 2 hospitals and different public places in the city of Wuhan, where the outbreak started.
Since of the relevance of their findings to the ongoing public health emergency, the scientists posted a full, unedited preprint of their study paper on the server bioRxiv on March 10,2020 An unedited abstract of the paper was likewise recently released in the journal Nature
The researchers utilized air purification gadgets called aerosol traps to collect a total of 35 samples from 31 locations between February 17 and March 2, 2020.
The variety of samples was relatively low because access to medical facilities became firmly limited at the peak of the outbreak.
In addition, the scientists highlight that their study did not develop whether the virus-laden aerosols were capable of contaminating individuals.
In restricted areas, nevertheless, aerosols are understood to transmit other pathogens, consisting of those that cause tuberculosis, measles, and chickenpox
Aerosol transmission might also have contributed in the spread of the coronavirus that triggered a break out of the respiratory infection SARS in Hong Kong in 2003.
The senior author of the present study was Dr. Ke Lan, of Wuhan University’s Modern Virology Proving ground, and the team likewise included public health specialists from Shanghai and Hong Kong.
They gathered aerosol samples from 2 healthcare facilities where COVID-19 patients were being treated.
