Talking to PV suckhoedoisong.vn about this issue, Associate Professor, Dr. Tran Minh Dien - Deputy Director of the National Children's Hospital said that if only one person uses an aerosol, it is fine; but if two people share it, they will get infected.
According to experts, COVID-19 can be spread through aerosols - a method of treatment, not "dust" as the press translates and not through "air" as the public understands.
On the other hand, if the aerosol in the sick room has a sick person within a distance of 2m, the disease will be transmitted because the virus from the patient's respiratory tract will be released through the aerosol. Therefore, it will be transmitted to people around.
"Therefore, it is necessary to limit aerosol use, unless prescribed by a doctor. When using aerosol, technical procedures for infection control must be followed.
Furthermore, the virus will still exist in the aerosol, machine and surface of objects around the patient, with the risk of infection due to surface contact. Medical staff performing this procedure on patients are also at risk of infection if they do not strictly follow the technical process of infection control," said Associate Professor Dien.

Associate Professor, Dr. Nguyen Thi Dieu Thuy - Head of the Department of Pediatrics, Hanoi Medical University also said that aerosol is transmitted through the air in the form of small mist particles. These small mist particles from the nebulizer can fly in the air, and people nearby who inhale high concentrations will be at risk of infection.
According to Dr. Truong Huu Khanh - Department of Infectious Diseases - Neurology, Children's Hospital 1, "aerosol", the new source of transmission that Shanghai scientists warned about, in this context should be translated as "aerosol", not "dust" which is incorrect and there is no way it can fly around in the air because aerosol is only used in medical facilities!
Therefore, the people who need to pay attention to this new discovery are hospitals and medical facilities when using aerosol to treat patients.

Previously, speaking at a press conference in Shanghai (China) on February 8, Mr. Zeng Qun - Deputy Director of the Shanghai Municipal Civil Affairs Bureau, said that medical and epidemic prevention experts have determined that COVID-19 can be transmitted through aerosols, according to Xinhua News Agency.
Some information says that aerosol is "dust gas" but according to experts, aerosol is a treatment method, the Vietnamese name is "aerosol".
Nebulization is a method of using a machine to diffuse medicine in the form of mist, affecting the upper or lower respiratory tract mucosal system. This is a local treatment method for diseases of the respiratory tract mucosa such as laryngitis, rhinopharyngitis, tracheobronchitis, sinusitis, etc. When inhaling, the medicine in the form of mist created by the machine will be pushed to adhere to the cilia on the respiratory tract mucosa. Thanks to that, the medicine will directly affect the infected areas.
So COVID-19 can be spread through aerosols - a method of treatment, not "dust" as the press translates and not through "air" as the public understands.
