Extend the validity of the Green pass to 72 hours in view of October 15, when green certification will become mandatory in the workplace. To ask the Regions and the leader of the Lega Matteo Salvini. From Matteo Bassetti to Massimo Andreoni, what do the experts think?
This request “risks making this tool useless,” Matteo Bassetti, director of the Infectious Diseases Clinic of the San Martino Polyclinic in Genoa, told Adnkronos Health. “Maybe it will be decided that a tampon once a week is fine – he added – As usual we did the Italian Green pass, while it was done in the French way: you get it if you get vaccinated, if you have had the disease or if you have problems So it really doesn’t make any sense, continuing will just be a disaster because we don’t know how to do 10-12 million tampons a week.
Extending the validity of the swab to 72 hours to obtain the Green pass “is a measure not based on scientific evidence and not prudent. The period is too long. The swab is a punctual measure of negativity. So prolong this excessively. period of time exposes you to risk “. This is the opinion of Walter Ricciardi, advisor to the Minister of Health Roberto Speranza and professor of Hygiene at the Catholic University of Rome. “The fact that the swab itself gives a series of false negatives is associated with the fact that, as the time window increases, the possibility of getting infected increases. So it is better to be cautious”, explains Ricciardi to Adnkronos Salute. Minister Speranza’s advisor stresses that “it is necessary to remain within the scope of scientific evidence. We have understood well that every time we deviate from scientific evidence we have encountered problems. All countries that have not made decisions based on data science has compromised both health and the economy. So it’s good to stick to what we know. “
“I don’t think we can think of extending the duration of the validity of the antigen tests for the Green pass to 72 hours, it is not an acceptable safety margin for a test that already has a lower sensitivity than the Pcr buffer”. Massimo Andreoni, head of Infectious Diseases at the Tor Vergata Polyclinic in Rome and scientific director of the Italian Society of Infectious and Tropical Diseases (Simit), is a drastic no. “Thinking of moving to 72 hours means running the risk of missing some asymptomatic positive and we cannot afford it – underlines Adnkronos Salute Andreoni – Personally I would not feel like considering this hypothesis for antigenic texts”. On the possibility of an extension to the deadline of October 15 proposed by the Regions, the infectious disease specialist points out “that there was time to organize and the fact that today it is said that they are not ready leaves me perplexed, and then – he concludes – there is an operational machine capable of performing hundreds of thousands of tests “.
