In the last month, between 8 December and 8 January, at the Clinical Research Institute High medical 16,030 molecules were performed, of which 2,526 (15.7%) were positive. The symptoms were as follows: out of 16,030 subjects 12,503 (78%) asymptomatic, 2,885 (18%) paucisymptomatic (low-grade fever, angina), symptomatic 642 (4%) fever greater than 38 ° or other more evident symptoms. The symptomatology of the positives was the following: asymptomatic 1,692 (67%), paucisymptomatic 707 (28%), symptomatic: 127 (5%) fever greater than 38 ° or other evident symptoms but without the need for hospitalization. The vaccinated were 2071 (82%), 1 or 2 files; 1739 (84%); booster 332 (16%). The unvaccinated were 455 (18%)
As for the more severe symptoms (samples taken at home) temperature higher than 38 ° or other evident symptoms but without any need for hospitalization at the time of collection, i unvaccinated were 32 out of 455 (7%) while and vaccinates 95 are 2,071 (4.5%). The difference was only moderately significant from a statistical point of view (Chi-Square Test, p=0.03).
The data of the study
“The data of the large sample collected in one month of swabs in the Altamedica Research Center show that the pandemic is fading, in large numbers, increasingly towards an asymptomatic, paucisymptomatic or symptomatic flu but without the need for hospitalization, if normally assisted at home – explains Prof Claudio Giorlandino, scientific director of the Altamedica Research Clinical Institute – These forms, enormously more represented than the severe forms that require hospitalization in intensive care, almost equally affect vaccinated and unvaccinated ”.
“The variant B.1.1.529, called Omicron, presenting many mutations of the Spike protein, demonstrates a significant escape compared to the vaccines used aimed at inducing immunity on a protein S extremely mutated over time – adds Giorlandino – It should be emphasized that the number of positive subjects follows the number of swabs performed. Italy is in first place in the execution of swabs, largely useless or even harmful such as immunochromatographic antigenic agents (the soaps) which provide a huge number of false negatives freeing contagious asymptomatic subjects (called superspreaders) “.
“Of great importance it is the fact that the Omicron variant, which according to the latest ISS data on 7,000 subjects examined (surveillance 23 October / 6 December 2021) seemed to affect only 0.1%, instead is now close to 30% and is rapidly increasing weekly equal to passu to the weakening of the aggressiveness of the virus “, says the expert.
