The severe epidemiological picture that prevails in Shanghai with the onslaught of coronavirus and the suffocating restrictive measures it has led to, the National Public Health Organization (NPHO) is attempting to unravel. According to the body responsible for Greece, the unprecedented scene that has been set up in the Chinese pol does not hide any alarming scientific data, such as a new mutation of the coronavirus, but only the insistence on adopting the "zero dispersion" strategy[/B] that was followed in China from the very beginning.
"Based on the data published by China, there is no evidence of a new variant of the virus, or any other given that the pandemic has changed characteristics," underlines the EHRC in a statement.
"The unprecedented images of the severe restrictive measures in Shanghai, China have alarmed the international community. Restrictive measures are in place in Shanghai including suspension of professional and social activities and isolation of people diagnosed positive for the SARS-CoV-2 coronavirus," the agency says.
The "zero dispersal" strategy
As a reminder, after the outbreak during the first pandemic period (January-February 2020), China had a near-zero number of cases until early March this year.
"This was a consequence of the 'zero dispersal' or zero-Covid strategy, which involved applying strict restrictive measures in case of detection of a small number of cases of SARS-CoV-2. The 'zero-dispersion' strategy was successful until recently but not after February 2022 when a dispersion of the Omicron variant and in particular the Omicron 2 subgroup (BA.2), which has high infectivity and immune escape characteristics," explain the Greek experts of the Agency.
"Due to the high infectivity of the Omicron variant and the lower effectiveness of the vaccines used in China, this strategy is less effective and requires the implementation of very strict measures," says EODY, concluding that "in conclusion, the existing data from China do not indicate the existence of a new variant of the virus or any other factor that raises concern regarding the course of the pandemic."
