This time last year was the first major outbreak of the CCP virus in the world, when Japanese scientists initially revealed the principle of airborne transmission of the virus, known as aerogel transmission, through experiments that led to a better understanding of the importance of maintaining social distance, wearing masks and reducing group gatherings.
A year has passed, and as the CCP virus continues to mutate strongly, the epidemic has spread to almost every country in the world. More than 140 million people have been confirmed infected worldwide, including more than 3.01 million deaths. The overall global epidemic is still uncontrollable and the role of various vaccines has proven to be very limited. Dr. Yan Limeng came to the U.S. last year and immediately pointed out that an effective vaccine would not be available unless the CCP handed over the genetic map of the virus gain modification. Therefore, since the world has not yet found an effective way to control the epidemic (e.g., exterminate CCP), a full understanding of how the CCP virus is transmitted and changing social behavior to reduce the risk of infection is not a bad way to respond.
A recent study published in The Lancet, which was reviewed and approved by experts, suggests that the CCP virus is primarily airborne. According to the report, it is well known that humans congregate in environments with limited space and poor ventilation, such as concerts, cruise ships, slaughterhouses, nursing homes and correctional facilities, where they are most likely to be infected, and less well known is that remote transmission of the CCP virus is also a cause of outbreaks. Such cases of remote infection by transmitters from different rooms in isolated hotels have been confirmed. It was previously believed that it was difficult to transmit the aerogel containing the virus if the infected person did not cough or sneeze, which has now been shown to be false.
The researchers collected 13 air samples for scientific experiments in cars, bedrooms, hospitals, and other environments where people infected with CCP virus have stayed, and found that airborne CCP virus can remain infectious for up to 3 hours, with a half-life of 1-1 hours. This means that there is a risk of infection when exposed to this air with the virus within 3 hours. The researchers say that there are differences between the test and the reality, from sample collection to experimental analysis, but they do not prevent the introduction of formal conclusions. The researchers believe that there are several factors that can explain why some people are infected and others are not in the same transmission space, such as geometric variation in the amount of virus excreted and different environmental conditions (especially ventilation). as differences in individual factors.
The researchers point out that ventilation of the indoor space is very important, as circulating air can effectively dilute the aerogel content; although the hospital is crowded, aerogel transmission is effectively controlled with adequate protection and the transmission rate is not high. Experts from the United States, United Kingdom and Canada have called on the public health community of governments to act as soon as possible to raise awareness that airborne transmission of the virus is the main reason for the proliferation of the epidemic, and to develop standards to effectively reduce airborne transmission, which is urgent!
