In the results of an intentional infection test for COVID-19 announced by Dr. Christopher Chu’s team at Imperial College London (ICL) in the UK, some infected people released the virus for 12 days.
According to CNN broadcast on the 31st of last month (local time), Dr. Christopher Chu’s team at Imperial College London (ICL), UK, recruited healthy volunteers aged 18 to 30 and conducted a study on the intentional infection of COVID-19 in March last year. The results were published in Nature Medicine.
The research team selected healthy individuals without any risk factors for COVID-19, such as overweight or obesity, kidney and liver dysfunction, heart disease, and lung and blood problems, among volunteers, and conducted the experiment following providing sufficient information regarding the study.
Using a long, thin tube, a small drop of liquid containing the original Corona 19 virus was injected into the nostrils, and infection and symptoms were observed in a negative pressure room 24 hours a day for 2 weeks.
As a result, it was confirmed that 18 people, regarding half of the participants, were infected with COVID-19. Two patients were asymptomatic, and all 16 patients with symptoms were mild, such as stuffy nose, sneezing, and sore throat.
In this study, it was also found that even a single drop of liquid as small as 10 μm can cause COVID-19. In addition, it has been shown that the incubation period is short, and it begins to release the virus two days following infection and releases it for regarding six and a half days. Some infected people release the virus for 12 days.
In addition, it was found that the amount of virus emitted following infection was large even before symptoms appeared, and it was found that asymptomatic infected people also released a large amount of virus.
Dr. Chu said, “This experiment was very successful, and as the next study, we plan to conduct an intentional infection test to see how the vaccinees react when they are infected with the delta mutation.”
Although the study was conducted with various safety measures, it was controversial in that it intentionally injects viruses or pathogens into humans.
